ExtraHop REST API Guide

Introduction to the ExtraHop REST API

The ExtraHop REST API enables you to automate administration and configuration tasks on your ExtraHop system. You can send requests to the ExtraHop API through a Representational State Transfer (REST) interface, which is accessed through resource URIs and standard HTTP methods.

When a REST API request is sent over HTTPS to an ExtraHop system, that request is authenticated and then authorized through an API key. After authentication, the request is submitted to the ExtraHop system and the operation completes.

Each ExtraHop system provides access to the built-in ExtraHop REST API Explorer, which enables you to view all of the available system resources, methods, properties, and parameters. The REST API Explorer also enables you to send API calls directly to your ExtraHop system.

Note:

This guide is intended for an audience that has a basic familiarity with software development and the ExtraHop system.

ExtraHop API requirements

Before you can begin writing scripts for the ExtraHop REST API or performing operations through the REST API Explorer, you must meet the following requirements:

Your ExtraHop system must be configured to allow API key generation for the type of user you are (remote or local).
You must generate a valid API key.
You must have a user account on the ExtraHop system with appropriate privileges set for the type of tasks you want to perform.

Access and authenticate to the ExtraHop REST API

Setup users and users with system and access administration privileges control whether users can generate API keys. For example, you can prevent remote users from generating keys or you can disable API key generation entirely. When this functionality is enabled, API keys are generated by users and can be viewed only by the user who generated the key.

Note:

Administrators set up user accounts and assign privileges, but then users generate their own API keys. Users can delete API keys for their own account, and users with system and access administration privileges can delete API keys for any user. For more information, see Users and user groups.

After you generate an API key, you must append the key to your request headers. The following example shows a request that retrieves metadata about the firmware running on the ExtraHop system:

curl -i -X GET --header "Accept: application/json" \
--header "Authorization: ExtraHop apikey=2bc07e55971d4c9a88d0bb4d29ecbb29" \
"https://<hostname-or-IP-of-your-ExtraHop-system>/api/v1/extrahop"

Privilege levels

User privilege levels determine which ExtraHop system and administration tasks the user can perform through the ExtraHop REST API.

You can view the privilege levels for users through the granted_roles and effective_roles properties. The granted_roles property shows you which privilege levels are explicitly granted to the user. The effective_roles property shows you all privilege levels for a user, including those received outside of the granted role, such as through a user group.

The granted_roles and effective_roles properties are returned by the following operations:

GET /users
GET /users/{username}

The granted_roles and effective_roles properties support the following privilege levels. Note that the type of tasks for each ExtraHop system vary by the available resources listed in the REST API Explorer and depend on the modules enabled on the system and user module access privileges.

Privilege level	Actions allowed
"system": "full"	Enable or disable API key generation for the ExtraHop system. Generate an API key. View the last four digits and description for any API key on the system.

This is an add-on privilege that can be granted to a user with one of the following privilege levels: "write": "full" "write": "limited" "write": "personal" "write": null "metrics": "full" "metrics": "restricted"

Manage API key access

Users with system and access administration privileges can configure whether users can generate API keys for the ExtraHop system. You can allow only local users to generate keys, or you can also disable API key generation entirely.

Users must generate an API key before they can perform operations through the ExtraHop REST API. Keys can be viewed only by the user who generated the key or system administrators with unlimited privileges. After a user generates an API key, they must append the key to their request headers.

Log in to the Administration settings on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
In the Access Settings section, click API Access.
In the Manage API Access section, select one of the following options:
- Allow all users to generate an API key: Local and remote users can generate API keys.
- Only local users can generate an API key: Remote users cannot generate API keys.
- No users can generate an API key: No API keys can be generated by any user.
Click Save Settings.

Generate an API key

You must generate an API key before you can perform operations through the ExtraHop REST API. Keys can be viewed only by the user who generated the key or by users with system and access administration privileges. After you generate an API key, add the key to your request headers or the ExtraHop REST API Explorer.

Before you begin

Make sure the ExtraHop system is configured to allow API key generation.

In the Access Settings section, click API Access.
In the Generate an API Key section, type a description for the new key, and then click Generate.
Scroll down to the API Keys section, and copy the API key that matches your description.

You can paste the key into the REST API Explorer or append the key to a request header.

Cross-origin resource sharing (CORS) allows you to access the ExtraHop REST API across domain-boundaries and from specified web pages without requiring the request to travel through a proxy server.

You can configure one or more allowed origins or you can allow access to the ExtraHop REST API from any origin. Only users with system and access administration privileges can view and edit CORS settings.

In the Access Settings section, click API Access.
In the CORS Settings section, specify one of the following access configurations.
- To add a specific URL, type an origin URL in the text box, and then click the plus (+) icon or press ENTER.
  The URL must include a scheme, such as HTTP or HTTPS, and the exact domain name. You cannot append a path; however, you can provide a port number.
- To allow access from any URL, select the Allow API requests from any Origin checkbox.
  Note: Allowing REST API access from any origin is less secure than providing a list of explicit origins.
Click Save Settings and then click Done.

Set up an SSL certificate

Before making requests to an ExtraHop system with a self-signed certificate, you must set up an SSL certificate for each user who will access the ExtraHop system from a particular computer.

In each of the following examples, replace {HOST} with the hostname of your ExtraHop system.

Note:

The SSL certificate applies only to the user performing the command. Each user must run the command with their login credentials to set up the SSL certificate.

Set up SSL through Windows PowerShell

Invoke-WebRequest "http://{HOST}/public.cer" -OutFile ($env:USERPROFILE +
"\ex.cer"); Import-Certificate ($env:USERPROFILE + "\ex.cer")
-CertStoreLocation Cert:\CurrentUser\Root

Set up SSL through OS X

curl -O http://{HOST}/public.cer; security add-trusted-cert -r trustRoot -k
~/Library/Keychains/login.keychain public.cer

Learn about the REST API Explorer

The REST API Explorer is a web-based tool that enables you to view detailed information about the ExtraHop REST API resources, methods, parameters, properties, and error codes. Code samples are available in Python, cURL, and Ruby for each resource. You also can perform operations directly through the tool.

Open the REST API Explorer

You can open the REST API Explorer from the Administration settings or through the following URL:

https://<extrahop-hostname-or-ip-address>/api/v1/explore/

Log in to the Administration settings on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
From the Access Setting section, click API Access.
On the API Access page, click REST API Explorer.
The REST API Explorer opens in your browser.

View operation information

From the REST API Explorer, you can click any operation to view configuration information for the resource.

The following table provides information about the sections available for resources in the REST API Explorer. Section availability varies by HTTP method. Not all methods have all of the sections listed in the table.

Section

Description

Body Parameters

Provides all of the fields for the request body and supported values for each field.

Parameters

Provides information about the available query parameters.

Responses

Provides information about the possible status codes for the resource. If you click Send Request, this section also includes the response from the server and the cURL, Python, and Ruby syntax required to send the specified request.

Tip:	Click Model to view descriptions of the fields returned in a response.

Identify objects on the ExtraHop system

Objects on the ExtraHop system can be identified by any unique value, such as the IP address, MAC address, name, or system ID. However, to perform API operations on a specific object, you must locate the object ID. You can easily locate the object ID through the following methods in the REST API Explorer.

The object ID is provided in the headers returned from a POST request. For example, if you send a POST request to create a page, the response headers display a location URL.
The following request returned the location for the newly created tag as /api/v1/tags/1 and the ID for the tag as 1.
```
{
 "date": "Tue, 09 Nov 2021 18:21:00 GMT ",
 "via": "1.1 localhost",
 "server": "Apache",
 "content-type": "text/plain; charset=utf-8",
 "location": "/api/v1/tags/1",
 "cache-control": "private, max-age=0",
 "connection": "Keep-Alive",
 "keep-alive": "timeout=90, max=100",
 "content-length": "0"
}
```

The object ID is provided for all objects returned from a GET request. For example, if you perform a GET request on all devices, the response body contains information for each device, including the ID.

The following response body displays an entry for a single device, with an ID of 10212:

{
 "mod_time": 1448474346504,
 "node_id": null,
 "id": 10212,
 "extrahop_id": "test0001",
 "description": null,
 "user_mod_time": 1448474253809,
 "discover_time": 1448474250000,
 "vlanid": 0,
 "parent_id": 9352,
 "macaddr": "00:05:G3:FF:FC:28",
 "vendor": "Cisco",
 "is_l3": true,
 "ipaddr4": "10.10.10.5",
 "ipaddr6": null,
 "device_class": "node",
 "default_name": "Cisco5",
 "custom_name": null,
 "cdp_name": "",
 "dhcp_name": "",
 "netbios_name": "",
 "dns_name": "",
 "custom_type": "",
 "analysis_level": 1
},

The object ID is provided in the URL for most objects. For example, in the ExtraHop system, click on Assets, and then Devices. Select any device and view the URL. In the following example, the URL for the device page shows Oid=10180.
```
https://10.10.10.205/extrahop/#/Devices?details=true&device
Oid=10180&from=6&interval_type=HR&until=0&view=l2stats
```
To perform specific requests for that device, add 10180 to the id field in the REST API Explorer or to the body parameter in your request.

The URL for dashboards displays a short_code, which appears after /Dashboard. When you add the short_code to the REST API Explorer or to your request, you must prepend a tilde to the short code.

In the following example, kmC9Y is the short_code. To perform requests for this dashboard, add ~kmC9Y as the value for the short_code field.
```
https://10.10.10.205/extrahop/#/Dashboard/kmC9Y/?from=6&interval_
type=HR&until=0
```
You can also find the short_code and dashboard ID in the Dashboard Properties for any dashboard, which can be accessed from the command menu . Some API operations, such as DELETE, require the dashboard ID.

ExtraHop API resources

You can perform operations on the following resources through the ExtraHop REST API. You also can view more detailed information about these resources, such as available HTTP methods, query parameters, and object properties in the REST API Explorer.

Activity Map

An activity map is a dynamic visual representation of the L4-L7 protocol activity between devices in your network. Create a 2D or 3D layout of device connections in real-time to learn about the traffic flow and relationships between devices.

Here are some important considerations about activity maps:

You can only create activity maps for devices in Standard Analysis and Advanced Analysis. Discovery Mode devices are not included in activity maps. For more information, see Analysis levels.
If you create an activity map for a device, activity group, or device group with no protocol activity in the selected time interval, the map appears without any data. Change the time interval or your origin selection and try again.
You can create an activity map in a console to view device connections across all of your sensors.

To learn about configuring and navigating activity maps, see Activity maps.

The following table displays all of the operations you can perform on this resource:

Operation	Description
GET /activitymaps	Retrieve all activity maps.
POST /activitymaps	Create a new activity map.
POST /activitymaps/query	Perform a network topology query, which returns activity map data in flat file content.
DELETE /activitymaps/{id}	Delete a specific activity map.
GET /activitymaps/{id}	Retrieve a specific activity map.
PATCH /activitymaps/{id}	Update a specific activity map.
POST /activitymaps/{id}/query	Perform a topology query for a specific activity map, which returns activity map data in flat file content.
GET /activitymaps/{id}/sharing	Retrieve the users and their sharing permissions for a specific activity map.
PATCH /activitymaps/{id}/sharing	Update the users and their sharing permissions for a specific activity map.
PUT /activitymaps/{id}/sharing	Replace the users and their sharing permissions for a specific activity map.

Analysis Priority

The ExtraHop system analyzes and classifies traffic for every device it discovers. Your license reserves capacity for the ExtraHop system to collect metrics for high value devices. This capacity is associated with two analysis levels: Advanced Analysis and Standard Analysis.

You can specify which devices receive Advanced Analysis and Standard Analysis levels by configuring analysis priority rules. Analysis priorities help inform the ExtraHop system about which devices are important in your environment. A third analysis level, Discovery Mode, is available for devices that are not in Advanced or Standard Analysis.

Note:

By default, each sensor manages its own analysis priorities. If the sensor is connected to a console, you can centrally manage these shared system settings from the console.

The following table displays all of the operations you can perform on this resource:

Operation	Description
GET /analysispriority/config/{sensor_id}	Retrieve the analysis priority rules for a specific sensor.

Supported time units

For most parameters, the default unit for time measurement is milliseconds. However, the following parameters return or accept alternative time units such as minutes and hours:

Device
- active_from
- active_until
Device group
- active_from
- active_until
Metrics
- from
- until
Record Log
- from
- until
- context_ttl

The following table displays supported time units:

Time unit	Unit suffix
Year	`y`
Month	`M`
Week	`w`
Day	`d`
Hour	`h`
Minute	`m`
Second	`s`
Millisecond	`ms`

To specify a time unit other than milliseconds for a parameter, append the unit suffix to the value. For example, to request devices active in the last 30 minutes, specify the following parameter value:

GET /api/v1/devices?active_from=-30m

The following example specifies a search for HTTP records created between 1 and 2 hours ago:

{
    "from": "-2h",
    "until": "-1h",
    "types": ["~http"]
}

Device group

Device groups can be either static or dynamic.

A static device group is user-defined; you create a device group and then manually identify and assign each device to that group. A dynamic device group is defined and automatically managed by a set of configured rules.

For example, you can create a device group and then set a rule to classify all devices within a certain IP address range to be added to that group automatically. For more information, see Device Groups.

The following table displays all of the operations you can perform on this resource:

Operand values for device groups

The POST /devicegroups operation enables you to create device groups according to criteria specified in filter objects. Each object should contain a unique value for the operand field that is valid for the specified field value.

`activity`

To select devices by metric activity, specify the field value as activity and the operand value as a metric_category. You can find metric_category values in the REST API Parameters section of the Metric Catalog.

The following example selects devices with metric activity classified for a DHCP client, such as the number of DHCP requests sent.

{
    "filter":  {
        "field": "activity",
        "operand": "dhcp_client",
        "operator": "="
    }
}

Tip:	Programmatically retrieve a list of all metric activity for a device through the `GET /devices/{id}/activity` operation. The `stat_name` value matches the `metric_category` value in the `metric_catalog`, after the final dot.

In the following example response, the stat_name value is extrahop.device.dhcp_client. Remove the text before the final dot to identify the metric_catalog value of dhcp_client.

{
    "id": 198606,
    "from_time": 1581537120000,
    "until_time": 1581542520000,

{
    "filter":  {
        "field": "discover_time",
        "operand": {
            "from": "1566392400000",
            "until": "1566399600000"
        },

      {
        "field": "macaddr",
        "operand": "C1:1C:N2:0Q:PJ:10",
        "operator": "="
      },
      {
        "field": "macaddr",
        "operand": "C1:1C:N2:0Q:PJ:11",

{
  "filter": {
    "field": "software",
    "operand": "windows_10",
    "operator": "="
  }
}

Tip:

Programmatically retrieve a list of all software IDs associated with a device through the GET /devices/{id}/software operation.

In the following example response, the id value for the software is windows_10.

[
  {
    "software_type": "OS",

Search with regular expressions (regex)

For certain field values, the string can be in regex syntax. Specify the operand value as an object that has a value parameter with the regex syntax you want to match and an is_regex parameter that is set to true. The following example selects devices with DNS names that end with com.

{
    "filter":  {
        "field": "dns_name",
        "operand": {
            "value": ".*?com",
            "is_regex": true
        },
        "operator": "="
    }
}

An operand field with regex syntax is valid for the following field values:

cdp_name
custom_name
dns_name
dhcp_name
model
name
netbios_name
software
tag
vendor

Specify multiple criteria

You can specify multiple criteria with the rules field. The following example returns results for devices with an IP address of 192.168.12.0 or 192.168.12.1.

{
  "filter": {
    "operator": "or",
    "rules": [

Operand values for detection property tuning rules

The POST /detections/rules/hiding operation enables you to create tuning rules that filter detections based on detection properties. You can specify filtering criteria for detection properties in objects. Each object should contain a unique value for the operand field that is valid for the specified property value.

Tip:

You can retrieve valid property values through the GET /detections/formats operation. See the keys of the properties object in the response. In the following example, the property value is s3_bucket:

    "properties": {
      "s3_bucket": {
        "is_optional": true,
        "status": "active",
        "is_tunable": true,
        "data_type": "string"
      }
    }

The is_tunable field indicates whether you can create a tuning rule based on the property.

`registered_domain_name`

To hide rules by a registered domain name, specify the property value as registered_domain_name and the operand value as a domain name.

The following example rule hides DNS Tunnel detections for example.com.

{
    "detection_type": "dns_tunnel",
    "expiration": null,
    "offender": "Any",
    "victim": "Any",
    "properties": [
        {
            "operand": "example.com",
            "operator": "=",
            "property": "registered_domain_name"
        }
    ]
}

`uris`

To hide rules by a URI, specify the property value as uris and the operand value as a URI.

The following example rule hides SQL Injection (SQLi) Attack detections for http://example.com/test.

{
    "detection_type": "sqli_attack",
    "expiration": null,
    "offender": "Any",
    "victim": "Any",
    "properties": [
        {
            "operand": "http://example.com/test",
            "operator": "=",
            "property": "uris"
        }
      ]
}

`top_level_domain`

To hide rules by a top-level domain name, specify the property value as top_level_domain and the operand value as a top-level domain name.

The following example rule hides Suspicious Top-level Domain detections for the org top-level domain.

{
    "detection_type": "suspicious_tld",
    "expiration": null,
    "offender": "Any",
    "victim": "Any",
    "properties": [
        {
            "operand": "org",
            "operator": "=",
            "property": "top_level_domain"
        }
    ]
}

Search with regular expressions (regex)

For certain property values, the string can be in regex syntax. Specify the operand value as an object that has a value parameter with the regex syntax you want to match and an is_regex parameter that is set to true. The following rule filters DNS Tunnel detections with domain names that end with example.com.

{
    "detection_type": "dns_tunnel",
    "expiration": null,
    "offender": "Any",
    "victim": "Any",
    "properties": [
        {
            "operand": {
                "value": ".*?example.com",
                "is_regex": true
            },
            "operator": "=",
            "property": "registered_domain_name"
        }
    ]
}

Disable case sensitivity

By default, searches for string property values are case-sensitive. However, you can disable case sensitivity by specifying the operand value as an object that has a case_sensitive parameter that is set to false.

The following rule hides Hacking Tool Domain Access detections with the ArchStrike hacking tool.

{
    "detection_type": "hacking_tools",
    "expiration": null,
    "offender": "Any",
    "victim": "Any",
    "properties": [
        {
            "operand": {
                "value": "archstrike",
                "case_sensitive": false
            },
            "operator": "=",
            "property": "hacking_tool"
        }
    ]
}

Metrics

Metrics information is collected about every object identified by the ExtraHop system.

Note that metrics are retrieved through the POST method, which creates a query to collect the requested information through the API. For more information, see Extract metrics through the REST API.

The following table displays all of the operations you can perform on this resource:

Operation	Description
POST /metrics	Perform a metric query.
GET /metrics/next/{xid}	If a previous metric query requested activity group metrics from a console, the GET /metrics/next/{xid} operation retrieves metrics for the activity group on a connected sensor. Each time a request is sent to GET /metrics/next/{xid}, the operation returns metrics from a different sensor. After all metrics have been retrieved, the operation returns null.
POST /metrics/total	Perform a metric query for total values.
POST /metrics/totalbyobject	Perform a metric query for total values that are grouped by object.

For example, if you want to see all HTTP responses that occurred on the network in the last 30 minutes, enter the following request schema into the POST /metrics operation:

{
  "cycle": "auto",
  "from": -1800000,
  "metric_category": "http",
  "metric_specs": [
    {
      "name": "rsp"
    }
  ],
  "object_ids": [
    0
  ],
  "object_type": "application",
  "until": 0
}

The response body returns a list of HTTP responses and the time of each event, similar to the following output:

{   
  "stats": [     
    {       
      "oid": 0,
      "time": 1494539640000,
      "duration": 30000,
      "values": [
        354
      ]
    },
    {

Packet capture

You can retrieve and delete packets stored on the ExtraHop system.

Note:

For ExtraHop Reveal(x), this resource is not supported and has been replaced by the Packet Search resource.

You must write a trigger to identify the information you want to generate. For example, you can write a trigger to collect all of the packets going to a particular device that is generating a high volume of errors. Then, you can download or delete that information. For more information, see Packets.

The following table displays all of the operations you can perform on this resource:

Packet Search

You can search for and download packets stored on the ExtraHop system. The downloaded packets can then be analyzed through a third-party tool, such as Wireshark.

Note:

This resource can only retrieve packets from packetstores. To retrieve packets from a packet sensor, see the Packet Capture resource.

For more information about Packets, see Packets.

The following table displays all of the operations you can perform on this resource:

Operation	Description
GET /packets/search	Search for packets by specifying parameters in a URL.
POST /packets/search	Search for packets by specifying parameters in a JSON string.

Operation details

`GET /packets/search`

Specify the following parameters.

output: String

(Optional) The output format. * `pcap` - A PCAP file that contains packets. * `keylog_txt` - A keylog text file that contains secrets for decryption. * `pcapng` - A PCAPNG file that can contain both packets and secrets for decryption. * `zip` - A ZIP file that contains both a PCAP and keylog text file.

The following values are valid:

pcap
keylog_txt
pcapng
zip

include_secrets: Boolean

(Optional) Specifies whether to include secrets in the PCAPNG file. This option is valid only if `output` is set to `pcapng`.

limit_bytes: String

(Optional) The approximate maximum number of bytes to return. After the ExtraHop system finds packets that match the size specified in the search criteria, the system stops searching for additional packets. However, because the system analyzes multiple packets at a time, the total size of the packets returned might be larger than the specified size. The default unit is bytes, but you can specify other units with a unit suffix. The default value is "100MB".

limit_search_duration: String

(Optional) The approximate maximum amount of time to perform the packet search. After the specified amount of time has passed, the ExtraHop system stops searching for additional packets. However, the system will extend past the specified time to finish analyzing packets that were being searched before the time expired, and the system analyzes multiple packets at a time. Therefore, the search might last longer than the specified time. The default unit is milliseconds, but other units can be specified with a unit suffix. See the REST API Guide for supported time units and suffixes. The default value is "5m".

always_return_body: Boolean

(Optional) If you set this parameter to true, and the search does not match any packets, the system returns an empty packet capture file and an HTTP status of 200. If you set this parameter to false, and the search does not match any packets, the system returns no packet capture file and an HTTP status of 204.

from: String

The beginning timestamp of the time range the search will include, expressed in milliseconds since the epoch. A negative value specifies that the search will begin with packets captured at a time in the past. For example, specify -10m to begin the search with packets captured 10 minutes before the time of the request. Negative values can be specified with a time unit other than milliseconds, such as seconds or hours. See the REST API Guide for supported time units and suffixes.

until: String

(Optional) The ending timestamp of the time range the search will include, expressed in milliseconds since the epoch. A 0 value specifies that the search will end with packets captured at the time of the search. A negative value specifies that the search will end with packets captured at a time in the past. For example, specify -5m to end the search with packets captured 5 minutes before the time of the request. Negative values can be specified with a time unit other than milliseconds, such as seconds or hours. See the REST API Guide for supported time units and suffixes.

Filter packets with Berkeley Packet Filter syntax

Search for packets with the Berkeley Packet Filter (BPF) syntax alone, or in combination with the built-in filters.

Berkeley Packet Filters are a raw interface to data link layers and are a powerful tool for intrusion detection analysis. The BPF syntax enables users to write filters that quickly drill down on specific packets to see the essential information.

The ExtraHop system constructs a synthetic packet header from the packet index data and then runs the BPF syntax queries against the packet header to ensure that queries are much faster than scanning the full packet payload. Note that ExtraHop supports only a subset of the BPF syntax. See Supported BPF syntax.

The BPF syntax consists of one or more primitives preceded by one or more qualifiers. Primitives usually consist of an ID (name or number) preceded by one or more qualifiers. There are three different kinds of qualifiers:

type: Qualifiers that indicate what type the ID name or number refers to. For example, host, net, port, and portrange. If there is no qualifier, host is assumed.
dir: Qualifiers that specify a particular transfer direction to and or from an ID. Possible directions are src, dst, src and dst, and src or dst. For example, dst net 128.3.
proto: Qualifiers that restrict the match to the particular protocol. Possible protocols are ether, ip, ip6, tcp, and udp.

Add a filter with BPF syntax

Log in to the ExtraHop system through https://<extrahop-hostname-or-IP-address>.
From the top menu, click Packets.
In the trifield filter section, select BPF, and then type your filter syntax. For example, type src portrange 80-443 and net 10.10.
Click Download PCAP to save the packet capture with your filtered results.

Supported BPF syntax

The ExtraHop system supports the following subset of the BPF syntax for filtering packets.

Note:

ExtraHop only supports numeric IP address searches. Hostnames are not allowed.
Indexing into headers, […], is only supported for tcpflags and ip_offset. For example, tcp[tcpflags] & (tcp-syn|tcp-fin) != 0
ExtraHop supports both numeric and hexadecimal values for VLAN ID, EtherType, and IP Protocol fields. Prefix hexadecimal values with 0x, such as 0x11.

Primitive	Examples	Description
`[src\|dst] host <host ip>`	`host 203.0.113.50` `dst host 198.51.100.200`	Matches a host as the IP source, destination, or either. These host expressions can be specified in conjunction with other protocols like ip, arp, rarp or ip6.
`ether [src\|dst] host <MAC>`	`ether host 00:00:5E:00:53:00` `ether dst host 00:00:5E:00:53:00`	Matches a host as the Ethernet source, destination, or either.
`vlan <ID>`	`vlan 100`	Matches a VLAN. Valid ID numbers are `0-4095`. VLAN priority bits are zero. If the original packet had more than one VLAN tag, the synthetic packet the BPF matches against will only have the innermost VLAN tag.
`[src\|dst] portrange <p1>-<p2>` or `[tcp\|udp] [src\|dst] portrange <p1>-<p2>`	`src portrange 80-88` `tcp dst portrange 1501-1549`	Matches packets to or from a port in the given range. Protocols can be applied to a port range to filter specific packets within the range.
`[ip\|ip6][src\|dst] proto <protocol>`	`proto 1` `src 10.4.9.40 and proto ICMP` `ip6 and src fe80::aebc:32ff:fe84:70b7 and proto 47` `ip and src 10.4.9.40 and proto 0x0006`	Matches IPv4 or IPv6 protocols other than TCP and UDP. The protocol can be a number or name.
`[ip\|ip6][tcp\|udp] [src\|dst] port <port>`	`udp and src port 2005` `ip6 and tcp and src port 80`	Matches IPv4 or IPv6 packets on a specific port.
`[src\|dst] net <network>`	`dst net 192.168.1.0` `src net 10` `net 192.168.1.0/24`	Matches packets to or from a source or destination or either, that reside in a network. An IPv4 network number can be specified as one of the following values: Dotted quad (x.x.x.x) Dotted triple (x.x.x) Dotted pair (x.x) Single number (x)
`[ip\|ip6] tcp tcpflags & (tcp-[ack\|fin\|syn\|rst\|push\|urg\|)`	`tcp[tcpflags] & (tcp-ack) !=0` `tcp[13] & 16 !=0` `ip6 and (ip6[40+13] & (tcp-syn) != 0)`	Matches all packets with the specified TCP flag
Fragmented IPv4 packets (ip_offset != 0)	`ip[6:2] & 0x3fff != 0x0000`	Matches all packets with fragments.

The value that the query attempts to match. The query compares the value of the operand to the contents of the field parameter and applies the compare method specified by the operator parameter. You can explicitly specify the operand data type as described in the REST API Guide.

rules: Array of Objects

The list of one or more filter objects within a single filter object. Filter objects can be embedded recursively. Only "and", "or", and "not" operators are allowed for this parameter.

context_ttl: Number

The amount of time to keep the search context active. The specified value is interpreted as a duration into the future. The default unit is milliseconds, but other units can be specified with a unit suffix. See the REST API Guide for supported time units and suffixes. If a non-null value is specified, the response includes a cursor ID that is accepted by POST /records/cursor/. This parameter is not supported for third-party recordstores.

Specify the body parameter in the following JSON format.

{
    "context_ttl": 0,
    "filter": {
        "field": "string",
        "operator": "string",
        "operand": "string",
        "rules": []
    },
    "from": 0,
    "limit": 0,
    "offset": 0,
    "sort": {
        "field": "string",
        "direction": "string"
    },
    "types": [],
    "until": 0
}

`POST /records/cursor`

Specify the following parameters.

body: Object

The cursor ID that specifies the next page of results in the query.

cursor: String: The unique identifier of the cursor that specifies the next page of results in the query.

Specify the body parameter in the following JSON format.

{
    "cursor": "string"
}

context_ttl: Number

(Optional) The amount of time to keep the search context active, expressed in milliseconds.

`GET /records/cursor/{cursor}`

Specify the following parameters.

cursor: String: The cursor ID.
context_ttl: Number: (Optional) The amount of time to keep the search context active, expressed in milliseconds.

If the request is successful, the ExtraHop system returns an object in the following format.

{
    "cursor": "string",
    "from": 0,
    "records": {},
    "total": 0,
    "until": 0,
    "warnings": {}
}

Operand values in record queries

The operand field in the POST /records/search method specifies the value that a record query attempts to match. You can specify either the value only or both the data type and the value. If you specify only the value, the query will refer to the record format associated with the field parameter to determine the data type of the value.

For example, if you want to search for an IP address, you can specify an IP address data type, and then provide the actual address as the value.

The following example explicitly specifies the data type and value of the operand:

{
    "from": -1000,
    "filter": {
        "field" : "senderAddr",
        "operator": "=",
        "operand" : { "type" : "ipaddr4", "value": "1.2.3.4" }
    }
}

The following example specifies only the value of the operand:

{
    "from": -1000,
    "filter": {
        "field" : "senderAddr",
        "operator": "=",
        "operand" : "1.2.3.4"
    }
}

You can explicitly specify the following data types in the operand field:

application
boolean
device
Note: You must specify the discovery ID of the device in the value field. You can find the discovery ID of a device through the GET /devices method.
device_filter
device_group
flowinterface
flownetwork
ipaddr4
ipaddr6
number
network_locality
object
string

The operand field supports CIDR notation when filtering by IP addresses; the operator field must be set to "=" or "!=".

You can specify multiple filters by including the rules option, as shown in the following example:

{
  "filter": {
    "operator": "and",
    "rules": [
      {
        "field": "method",
        "operand": "SMB2_READ",
        "operator": "="
      },
      {
        "field": "reqL2Bytes",
        "operand": "100",
        "operator": ">"
      }
    ]
  },
  "types": [
    "~cifs"
  ],
    "from": "-30m"
}

Query records with a device group filter

To filter records by device group in the REST API, you must send a POST request to the /records/search endpoint with a record query filter that meets the following criteria:

The field must specify devices, such as client, server, sender, or receiver.
The operator must be either in or not_in.
The operandtype must be device_group.
The operandvalue must be a string representation of the numerical device group ID. You can retrieve device group IDs by running the GET /devicegroup operation and viewing the contents of the id field in the response.

For example, the following query searches for records in which the client device was a member of a device group with an ID of 200:

{
    "from": "-30m",
    "filter": {
        "field": "client",
        "operator": "in",
        "operand": {
            "type": "device_group",
            "value": "200"
        }
    }
}

You can also filter records by device group criteria without creating a device group by specifying the operand type as device_filter. For example, the following query searches for records in which the client device is running Windows 10:

{
    "from": "-30m",
    "filter": {
        "field": "client",
        "operator": "in",
        "operand": {
            "type": "device_filter",
            "value": {
                "field": "software",
                "operand": "windows_10",
                "operator": "="
            }
        }
    }
}

Note:

Operand values with type device_filter for record search are formatted the same as device search filters. For more information, see Operand values for device groups.

Query records with a network locality filter

To filter records by device group in the REST API, you must send a POST request to the /records/search endpoint with a record query filter that meets the following criteria:

The field must be a record field that specifies an IP address such as clientAddr, serverAddr, senderAddr, or receiverAddr.
The operator must be either in or not_in.
The operand type must be network_locality.
The operand value must be a string representation of a numerical network locality ID. You can view locality IDs with the GET /networklocalities operation.

For example, the following query searches for records where the client device is in a network locality with an ID of 123:

{
    "from": "-30m",
    "filter": {
        "field": "clientAddr",
        "operand": {
            "type": "network_locality",
            "value": "123"
        },
        "operator": "in"
    }
}

Supported time units

For most parameters, the default unit for time measurement is milliseconds. However, the following parameters return or accept alternative time units such as minutes and hours:

Device
- active_from
- active_until
Device group
- active_from
- active_until
Metrics
- from
- until
Record Log
- from
- until
- context_ttl

The following table displays supported time units:

Time unit	Unit suffix
Year	`y`
Month	`M`
Week	`w`
Day	`d`
Hour	`h`
Minute	`m`
Second	`s`
Millisecond	`ms`

GET /api/v1/devices?active_from=-30m

The following example specifies a search for HTTP records created between 1 and 2 hours ago:

{
    "from": "-2h",
    "until": "-1h",
    "types": ["~http"]
}

Report

A report is a PDF file of a dashboard that you can schedule for email delivery to one or more recipients. You can specify how often the report email is delivered and the time interval for dashboard data included in the PDF file.

Important:

You can only schedule reports from an ECA VM.

Here are some important considerations about dashboard reports:

You can only create a report for dashboards that you own or have been shared with you. Your ability to create a report is determined by your user privileges. Contact your ExtraHop administrator for help.
Each report can only link to one dashboard.
If you created a report for a dashboard that was later deleted or became inaccessible to you, the scheduled email will continue to be sent to recipients. However, the email will not include the PDF file and will instead notify recipients that the dashboard is unavailable to the report owner.

The following table displays all of the operations you can perform on this resource:

Operation	Description
GET /reports	Retrieve all reports.
POST /reports	Create a report.
DELETE /reports/{id}	Delete a specific report.
GET /reports/{id}	Retrieve a specific report.

Threat Collection

The Threat Collection resource enables you to upload free and commercial offered by the security community to your Reveal(x) system.

You must upload threat collections individually to your Command appliance or Reveal(x) 360, and to all connected sensors.
Custom threat collections must be formatted in Structured Threat Information eXpression (STIX) as TAR.GZ files. Reveal(x) currently supports STIX version 1.0 - 1.2.
You can directly upload threat collections to Reveal(x) 360 systems for self-managed sensors. Contact ExtraHop Support to upload a threat collection to ExtraHop-managed sensors.
The maximum number of observables that a threat collection can contain depends on your platform and license. Contact your ExtraHop representative for more information.

Note:

This topic applies only to ExtraHop Reveal(x) Premium and Ultra.

Upgrade ExtraHop firmware through the REST API

You can automate upgrades to the firmware on your ExtraHop appliances through the ExtraHop REST API. This guide provides instructions to upgrade through the REST API Explorer, a cURL command, and a Python script.

Note:

If your appliance is connected to ExtraHop Cloud Services, you can simplify the upgrade process by viewing available firmware versions and downloading firmware directly to the system from ExtraHop Cloud Services. For more information, see Upgrade ExtraHop firmware through the REST API with ExtraHop Cloud Services.

While the firmware upgrade process is similar across all ExtraHop appliances, some appliances have additional considerations or steps that you must address before you install the firmware in your environment. If you need assistance with your upgrade, contact ExtraHop Support.

All appliances must meet the following requirements:

The firmware version must be compatible with your appliance model.
The firmware version on your appliance must be supported by the upgrade version.
Command appliances must be running firmware that is greater than or equal to their connected appliances.
Discover appliances must be running firmware that is greater than or equal to connected Explore and Trace appliances.

If your deployment only includes a sensor, proceed to the API Explorer, cURL or Python upgrade instructions.

If your deployment includes additional appliance types, you must address the following dependencies before proceeding with the upgrade instructions.

If your deployment includes...	Pre-upgrade tasks	Upgrade order
Command appliances	Reserve a maintenance window of an hour for Command appliances managing 50,000 devices or more.	Command appliance Discover appliances All Explore appliances (manager nodes, then data nodes) Trace appliances
Explore appliances	See Upgrading ExtraHop recordstores.
Trace appliances	None

Upgrade ExtraHop firmware through the REST API Explorer

Important:

The REST API Explorer is not available on Reveal(x) 360.

Download firmware and upgrade the appliance

Click POST /extrahop/firmware/download/url.
Click Try it out.
In the body field, specify the following fields:
firmware_url: The URL that the firmware .tar file can be downloaded from.

upgrade: Indicates whether to upgrade the appliance after the firmware download completes. Set this field to true.
The body field should look similar to the following example text:
```
{
  "upgrade": true,
  "firmware_url": "https://example.extrahop.com/eda/8.7.1.tar"
}
```
Click Send Request.
In the Response headers, note the value after the last forward slash in the location header. You will need this value to monitor the progress of the upgrade job. For example, the job ID in the following example is ebbdbc9e-7113-448c-ab9b-cc0ec2307702
```
/api/v1/jobs/ebbdbc9e-7113-448c-ab9b-cc0ec2307702
```

Monitor the progress of the upgrade job

Click Jobs.
Click GET /jobs/{id}.
In the id field, type the value you copied from the location header in the previous task.
Click Send Request.
In the Response body, view information about the job.
The status field is DONE when the job is complete.

Upgrade ExtraHop firmware with cURL

You can upgrade the firmware on an appliance through the cURL command.

Before you begin

The cURL tool must be installed on your machine.
The system firmware .tar file must be downloaded on your machine.

Open a terminal application.
Download firmware and upgrade the appliance.
Run the following command, where YOUR_KEY is the API key for your user account, HOSTNAME is the hostname of your ExtraHop appliance, and FIRMWARE_URL is the URL that the firmware .tar file can be downloaded from:
```
curl -v -X POST https://HOSTNAME/api/v1/extrahop/firmware/download/url -H "Authorization: ExtraHop apikey=YOUR_KEY" -H "Content-Type: application/json" -d "{ \"upgrade\": true, \"firmware_url\": \"FIRMWARE_URL\"}"
```
In the command output, note the job ID in the Location header. For example, the job ID in the following example is ebbdbc9e-7113-448c-ab9b-cc0ec2307702:
```
< Location: /api/v1/jobs/ebbdbc9e-7113-448c-ab9b-cc0ec2307702
```
Monitor the progress of the upgrade job.
Run the following command, where YOUR_KEY is the API key for your user account HOSTNAME is the hostname of your appliance, and JOB_ID is the ID you recorded in the previous step:
```
curl -v -X GET https://HOSTNAME/api/v1/jobs/JOB_ID -H "Authorization: ExtraHop apikey=API_KEY"
```
The command displays an object that contains information about the upgrade job. The upgrade is complete when the status field is DONE. If the upgrade is not complete, wait a few minutes and run the command again.

Retrieve and run the example Python script

The ExtraHop GitHub repository contains an example Python script that upgrades multiple appliances by reading URLs, API keys, and firmware file paths from a CSV file.

Important:

The example python script authenticates to the sensor or console through an API key, which is not compatible with the Reveal(x) 360 REST API. To run this script with Reveal(x) 360, you must modify the script to authenticate with API tokens. See the py_rx360_auth.py script in the ExtraHop GitHub repository for an example of how to authenticate with API tokens.

Note:

The script does not automatically disable record ingest for ExtraHop recordstores. You must manually disable record ingest before running the script for an ExtraHop recordstores.

Go to the ExtraHop code-examples GitHub repository and download the contents of the upgrade_system directory to your local machine.
In a text editor, open the systems.csv file and replace the example values with the hostnames and API keys of your appliances.

Run the upgrade_system_url.py script.

The following arguments are optional:

--max-threads {int}: Specifies the maximum number of concurrent threads. The default value is 2.
--wait {float}: Specifies the number of minutes to wait before checking the progress of an upgrade job. The default value is 0.5.

For example, the following command upgrades a maximum of 3 appliances at a time:

python3 upgrade_system_url.py --max-threads 3

Note:

If the script returns an error message that the SSL certificate verification failed, make sure that a trusted certificate has been added to your sensor or console. Alternatively, you can add the verify=False option to bypass certificate verification. However, this method is not secure and not recommended. The following code sends an HTTP GET request without certificate verification:

requests.get(url, headers=headers, verify=False)

Upgrading ExtraHop recordstores

Pre-upgrade tasks

Before upgrading an ExtraHop recordstore, you must halt record ingest. You can halt record ingest for all of the nodes in a cluster from a single node.

Note:

The message Could not determine ingest status on some nodes and Error might appear on the Cluster Data Management page in the Administration settings of the upgraded nodes until all nodes in the cluster are upgraded. These errors are expected and can be ignored.

Open a terminal application.

Run the following command, where YOUR_KEY is the API for your user account, and HOSTNAME is the hostname of your ExtraHop recordstore:

curl -X PATCH "https://HOST/api/v1/extrahop/cluster" -H "accept: application/json" -H "Authorization: ExtraHop apikey=YOUR_KEY" -H "Content-Type: application/json" -d "{ \"ingest_enabled\": false}"

Post-upgrade tasks

After you have upgraded all of the nodes in the recordstore cluster, enable record ingest.

Open a terminal application.

Run the following command, where YOUR_KEY is the API for your user account, and HOSTNAME is the hostname of your ExtraHop recordstore:

curl -X PATCH "https://HOST/api/v1/extrahop/cluster" -H "accept: application/json" -H "Authorization: ExtraHop apikey=YOUR_KEY" -H "Content-Type: application/json" -d "{ \"ingest_enabled\": true}"

Change a dashboard owner through the REST API

Dashboards are owned by the logged in user that created them. If a user is no longer with your company, you might need to change the owner of the dashboard to maintain that dashboard.

To transfer ownership of a dashboard, you need the dashboard ID and the username of the dashboard owner. You can only view the username of the owner of a dashboard through the REST API.

Before you begin

You must log in to the sensor or console with an account that has system and access administration privileges to generate an API key.
You must have a valid API key to make changes through the REST API and complete the procedures below. (See Generate an API key.)
Familiarize yourself with the ExtraHop REST API Guide to learn how to navigate the ExtraHop REST API Explorer.

Retrieve the dashboard IDs

In a browser, navigate to the REST API Explorer.
The URL is the hostname or IP address of your sensor or console, followed by /api/v1/explore/. For example, if your hostname is seattle-eda, the URL is https://seattle-eda/api/v1/explore/.
Click Enter API Key and then paste or type your API key into the API Key field.
Click Authorize and then click Close.
Click Dashboard to display dashboard operations.
Click GET /dashboards.
Click Try it out and then click Send Request to send the request to your sensor or console.
Search for the dashboards by the dashboard name or by the user account listed in the "owner" field. If your list of dashboards is long, you can press control-F and search the response body.
For our example, we want to change the "LDAP Server Health" dashboard created by the user account for "marksmith":
```
{
    "id": 1876,
    "comment": null,
    "mod_time": 1507576983922,
    "author": "Mark Smith",
    "name": "LDAP Server Health",
    "owner": "marksmith",
    "built-in": false,
    "short_code": "MpXgk",
    "rights": [
      "transfer",
      "view",
      "edit",
      "share",
      "delete"
    ]
}
```
Note the number in the "id" field for each dashboard you want to modify.

Change the dashboard owner

Scroll down the page of Dashboard operations to the /dashboards/{id} section.
Click PATCH /dashboards/{id}.
Click Try it out.
The JSON schema is automatically added to the body parameter text box.
In the body text box, in the "owner" field, replace string with the username of the new owner.
In the id field, type the number you previously noted for the dashboard.
For our example, this value is 1876. (You can only modify one dashboard at a time through the REST API Explorer.)

In the following figure, we added the JSON "string" for the "owner" parameter to the body parameter text box, changed "string" to "paulanderson", and typed "1876" in the id field.
Click Send Request to send the request to your sensor or console.
Under Server response, the Code column displays 204 if the operation is successful. You can click GET /dashboards again to verify that the "owner" field has changed. Note that you can only change the dashboard owner. You cannot change the dashboard name or author fields through the REST API.
The dashboard is now available under My Dashboards in the ExtraHop system for the new user. As the new owner, you can now log in to your ExtraHop system and change other dashboard properties, such as the dashboard name or author.

Tip:	After you click Send Request, the REST API Explorer provides scripts for the operation in Curl, Python 2.7, or Ruby.

Python script example

The ExtraHop GitHub repository contains an example Python script that searches for all dashboards owned by a user account on a sensor or console and then changes the owner for all of those dashboards to another user account.

Important:

Go to the ExtraHop code-examples GitHub repository and download the change_dashboard_owner/change_dashboard_owner.py file to your local machine.
In a text editor, open the change_dashboard_owner.py file and replace the following configuration variables with information from your environment:

HOST: The IP address or hostname of the sensor or console.

API_KEY: The API key.

CURRENT: The username of the current dashboard owner.

NEW: The username of the new dashboard owner.

Run the following command:

python3 change_dashboard_owner.py

Note:

requests.get(url, headers=headers, verify=False)

Extract the device list through the REST API

The ExtraHop REST API enables you to extract the list of devices discovered by the sensor or console. By extracting the list with a REST API script, you can export the list in a format that can be read by third-party applications, such as a configuration management database (CMDB). In this topic, we show methods for extracting a list through both the cURL command and a Python script.

Before you begin

For sensors and ECA VMs, you must have a valid API key to make changes through the REST API and complete the procedures below. (See Generate an API key.)
For Reveal(x) 360, you must have valid REST API credentials to make changes through the REST API and complete the procedures below. (See Create REST API credentials.)

Retrieve the device list with the cURL command

The device list includes all device metadata, such as MAC addresses and device IDs. However, you can filter the list of devices with a JSON parser to extract the specific information you want to export. In this example, the device list is retrieved and then filtered with the jq parser to only extract the display name of each device.

Note:

The following procedure is not compatible with the Reveal(x) 360 REST API. To retrieve the device list from Reveal(x) 360, see Retrieve the device list from Reveal(x) 360 with the cURL command.

Before you begin

The cURL tool must be installed on your machine.
The jq parser must be installed on your machine. For more information, see https://stedolan.github.io/jq/.

Open a terminal application and run the following command, where YOUR_KEY is the API for your user account, HOSTNAME is the hostname of your sensor or console, and MAX_DEVICES is a number large enough to be more than the total number of devices discovered by your system:

curl -s -X GET --header "Accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY"  "https://HOSTNAME/api/v1/devices?active_from=1&active_until=0&limit=MAX_DEVICES" | jq -r '.[] | .display_name'

Note:

If the command returns no results, make sure that a trusted certificate has been added to your ExtraHop system. Alternatively, you can add the --insecure option to retrieve the device list from an ExtraHop system without a trusted certificate; however, this method is not secure and not recommended.

Tip:

You can append the select(.analysis == "LEVEL") option to filter results by analysis level. For example, the following command limits the results to include only devices that are selected for advanced analysis:

curl -s -X GET --header "Accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY"  "https://HOSTNAME/api/v1/devices?active_from=1&active_until=0&limit=10000000000"  | jq -r '.[] | select(.analysis == "advanced") | .display_name'

Tip:

You can append the select(.critical == BOOLEAN) option to filter results by the critical field. For example, the following command limits the results to include only devices that are identified as critical by the ExtraHop system:

curl -s -X GET --header "Accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY"  "https://HOSTNAME/api/v1/devices?active_from=1&active_until=0&limit=10000000000"  | jq -r '.[] | select(.critical == true) | .display_name'

Tip:

You can append the select(.cloud_instance_name != null) option to filter results by the cloud instance name field. For example, the following command limits the results to include only devices with a cloud instance name:

curl -s -X GET --header "Accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY"  "https://HOSTNAME/api/v1/devices?active_from=1&active_until=0&limit=10000000000"  | jq -r '.[] | select(.cloud_instance_name != null) | .cloud_instance_name'

Retrieve the device list from Reveal(x) 360 with the cURL command

Note:

The following procedure is only compatible with the Reveal(x) 360 REST API. To retrieve the device list from sensors and ECA VMs, see Retrieve the device list with the cURL command.

Before you begin

The cURL tool must be installed on your machine.
The jq parser must be installed on your machine. For more information, see https://stedolan.github.io/jq/.

Open a terminal application and run the following command, where REVEAL_X_360_REST_API is the hostname of the Reveal(x) 360 API. This hostname is displayed in Reveal(x) 360 on the API Access page under API Endpoint. The hostname does not include the /oauth/token:
```
HOST="https://REVEAL_X_360_REST_API"
```
Run the following command, where YOUR_ID is the ID of the REST API credentials:
```
ID="YOUR_ID"
```
Run the following command, where YOUR_SECRET is the secret of the REST API credentials:
```
SECRET="YOUR_SECRET"
```

Run the following command:

AUTH=$(printf "$ID:$SECRET" | base64 --wrap=0)

Run the following command:

ACCESS_TOKEN=$(curl -s \
    -H "Authorization: Basic ${AUTH}" \
    -H "Content-Type: application/x-www-form-urlencoded" \
    --request POST \
     ${HOST}/oauth2/token \
    -d "grant_type=client_credentials" \
    | jq -r '.access_token')

Run the following command, where MAX_DEVICES is a number large enough to be more than the total number of devices discovered by your system:

curl -s -X GET -H "Authorization: Bearer ${ACCESS_TOKEN}"  "$HOST/api/v1/devices?active_from=1&active_until=0&limit=MAX_DEVICES" | jq -r '.[] | .display_name'

Tip:

curl -s -X GET -H "Authorization: Bearer ${ACCESS_TOKEN}"  "$HOST/api/v1/devices?active_from=1&active_until=0&limit=10000000000" | jq -r '.[] | select(.analysis == "advanced") | .display_name'

Tip:

curl -s -X GET -H "Authorization: Bearer ${ACCESS_TOKEN}"  "$HOST/api/v1/devices?active_from=1&active_until=0&limit=10000000000"  | jq -r '.[] | select(.critical == true) | .display_name'

Tip:

curl -s -X GET -H "Authorization: Bearer ${ACCESS_TOKEN}"  "$HOST/api/v1/devices?active_from=1&active_until=0&limit=10000000000"  | jq -r '.[] | select(.cloud_instance_name != null) | .cloud_instance_name'

Retrieve and run the example Python script

The ExtraHop GitHub repository contains an example Python script that extracts the device list, including all device metadata, and writes the list to a CSV file in the same directory as the script.

Go to the ExtraHop code-examples GitHub repository and download the extract_device_list/extract_device_list.py file to your local machine.
In a text editor, open the extract_device_list.py file and replace the configuration variables with information from your environment.
- For sensors and ECA VMs, specify the following configuration variables:
  
  HOST: The IP address or hostname of the sensor or ECA VM.
  
  API_KEY: The API key.
  
  CSV_FILE: The file that contains the list of device groups.
  
  FILENAME: The file that output will be written to

Run the following command:

python3 extract_device_list.py

Note:

requests.get(url, headers=headers, verify=False)

Create a trusted SSL certificate through the REST API

By default, sensors and consoles include a self-signed SSL certificate. However, you can improve the security and performance of your system by adding a trusted certificate signed by a certificate authority (CA). You can create the certificate signing request to send to your CA through the ExtraHop REST API. After you receive the signed certificate, you can also add it to your sensor or console through the REST API.

Before you begin

You must log in to the sensor or console with an account that has system and access administration privileges to generate an API key.
You must have a valid API key to make changes through the REST API and complete the procedures below. (See Generate an API key.)
Familiarize yourself with the ExtraHop REST API Guide to learn how to navigate the ExtraHop REST API Explorer.

Note:

You can also perform the procedures in this topic through the Administration settings. For more information, see the following topics:

Create an SSL certificate signing request

To create a signed SSL certificate, you must send a certificate signing request to a trusted CA.

Important:

The REST API Explorer is not available on Reveal(x) 360.

In a browser, navigate to the REST API Explorer.
The URL is the hostname or IP address of your sensor or console, followed by /api/v1/explore/. For example, if your hostname is seattle-eda, the URL is https://seattle-eda/api/v1/explore/.
Click Enter API Key and then paste or type your API key into the API Key field.
Click Authorize and then click Close.
Click ExtraHop and then click POST/extrahop/sslcert/signingrequest.
Click Try it out.
The JSON schema is automatically added to the SSL Certificate Signing Request Parameters parameter text box.

In the SSL Certificate Signing Request Parameters parameter text box, specify the certificate signing request fields.

In the common_name field, replace string with the fully qualified domain name of your sensor or console.

In the subject_alternative_names field, add one or more alternative domain names or IP addresses for your sensor or console.

Note:

The subject_alternative_names field is required. If your system has only one domain name, duplicate the value from the common_name field. You must include at least one subject alternative name with the type set to dns, but additional alternative names can have the type set to ip or dns.

(Optional): In the email_address field, replace string with the email address of the certificate owner.
(Optional): In the organization_name field, replace string with the registered legal name of your organization.
(Optional): In the country_code field, replace string with the 2-character ISO country code of the country that your organization is located in.
(Optional): In the state_or_province_name field, replace string with the name of the state or that your organization is located in.
(Optional): In the locality_name field, replace string with the name of the city that your organization is located in.
(Optional): In the organizational_unit_name field, replace string with the name of your department within your organization.

The Value section should look similar to the following example:

{
  "subject": {
    "common_name": "example.com",
    "email_address": "admin@example.com",
    "organization_name": "Example",
    "country_code": "US"
  },
  "subject_alternative_names": [
    {
      "name": "www.example.com",
      "type": "dns"
    }
  ]
}

Click Send Request to create the signing request.
In the Server response section, the Response body displays the signing request in the pem field.

Next steps

Send the signing request to your CA to create your signed SSL certificate.

Important:

The signing request contains escape sequences that represent line breaks (\n). Replace each instance of \n with a line break before sending the request to your CA. You can modify the PEM request manually in a text editor or automatically through a JSON parsing utility, as shown in the following example command:

echo '<json_output>' | python -c 'import sys, json; print json.load(sys.stdin)["pem"]'

Replace the <json_output> variable with the entire JSON string returned in the Response Body section.

Add a trusted SSL certificate to your sensor or console

You can add an SSL certificate signed by a trusted CA to your sensor or console through the REST API Explorer.

In a browser, navigate to the REST API Explorer.
The URL is the hostname or IP address of your sensor or console, followed by /api/v1/explore/. For example, if your hostname is seattle-eda, the URL is https://seattle-eda/api/v1/explore/.
Click Enter API Key and then paste or type your API key into the API Key field.
Click Authorize and then click Close.
Click ExtraHop and then click PUT/extrahop/sslcert.
Click Try it out.

In the Certificate and Key field, paste the SSL certificate.

The certificate should look similar to the following text:

Note:

If you want the certificate to be signed with your own private key, you can include your key after the SSL certificate, separated by a line break. However, we recommend that you do not specify your own key; by default, the sensor or console will sign the certificate with the private key on the system.

Click Send Request to add the certificate.

Create custom devices through the REST API

You can create custom devices through the REST API that track network traffic across multiple IP addresses and ports. For example, you might want to add a custom device for each branch office. If you create the devices through a script, you can read the list of devices from a CSV file. In this topic, we will demonstrate methods for both the REST API and the ExtraHop REST API Explorer.

Before you begin

You must log in to the sensor with an account that has system and access administration privileges to generate an API key.
You must have a valid API key to make changes through the REST API and complete the procedures below. (See Generate an API key.)
Familiarize yourself with the ExtraHop REST API Guide to learn how to navigate the ExtraHop REST API Explorer.

Create a custom device through the REST API Explorer

You can create a custom device and associate the custom device with a list of IP addresses or CIDR blocks through the POST /customdevices operation.

Important:

The REST API Explorer is not available on Reveal(x) 360.

In a browser, navigate to the REST API Explorer.
The URL is the hostname or IP address of your sensor, followed by /api/v1/explore/. For example, if your hostname is seattle-eda, the URL is https://seattle-eda/api/v1/explore/.
Click Custom Device, and then click POST /customdevices.
In the body field, specify properties for the custom device that you want to create.
For example, the following body matches the custom device to the CIDR blocks 192.168.0.0/26, 192.168.0.64/27, 192.168.0.96/30, and 192.168.0.100/32:
```
{
  "description": "The location of our office in Washington",
  "name": "Seattle",
  "criteria": [
    {
      "ipaddr": "192.168.0.0/26"
    },
    {
      "ipaddr": "192.168.0.64/27"
    },
    {
      "ipaddr": "192.168.0.96/30"
    },
    {
      "ipaddr": "192.168.0.100/32"
    }
  ]
}
```

Retrieve and run the example Python script

The ExtraHop GitHub repository contains an example Python script that creates custom devices by reading criteria from a CSV file.

Go to the ExtraHop code-examples GitHub repository and download the create_custom_devices/create_custom_devices.py file to your local machine.

Create a CSV file with rows that contain the following columns in the specified order:

Name

Description

IP address or CIDR block

Tip:	The create_custom_devices directory contains an example CSV file named device_list.csv.

The script does not accept a header row in the CSV file. There is no limit to the number of columns in the table; each column after the first four specifies an additional IP address for the device. The first four columns are required for each row.

In a text editor, open the create_custom_devices.py file and replace the following configuration variables with information from your environment:

HOST: The IP address or hostname of the sensor.

APIKEY: The API key.

CSV_FILE: The path of the CSV file relative to the location of the script file.

Run the following command:

python3 create_custom_devices.py

Note:

requests.get(url, headers=headers, verify=False)

Create and assign a device tag through the REST API

Create, retrieve, and delete an object through the REST API

This example shows how you can create and successfully retrieve information about a device tag. Then, after the device tags are deleted, the example shows how an attempt to retrieve information subsequently fails.

The following example shows how to create a device tag called my_test_tag.

curl -i -X POST --header "Content-Type: application/json" \
--header "Accept: application/json" \
--header "Authorization: ExtraHop apikey={API KEY}" \
-d "{
\"name\": \"my_test_tag\"
}" "https://{HOST}/api/v1/tags"

A 201 status returns upon success with the following response headers, which display that the tag was created, and provides the device tag location and ID of /api/v1/tags/1.

{
 "date": "Wed, 18 Nov 2015 20:24:13 GMT",
 "via": "1.1 localhost",
 "server": "Apache",
 "content-type": "text/plain; charset=utf-8",
 "location": "/api/v1/tags/1",
 "cache-control": "private, max-age=0",
 "connection": "Keep-Alive",
 "keep-alive": "timeout=45, max=88",
 "content-length": "0"
}

Next, the ID (1) is added to the following GET request, which returns a 200 status upon success and the JSON representation of the retrieved tag:

curl -i -X GET --header "Accept: application/json" \
--header "Authorization: ExtraHop apikey={API KEY}" \
"https://{HOST}/api/v1/tags/1"
{
 "mod_time": 1447878253953,
 "id": 1,
 "name": "my_test_tag"
}

Next, the following example shows a DELETE request to remove the device tag from the system, which returns a 204 status upon success:

curl -i -X DELETE --header "Accept: application/json" \
--header "Authorization: ExtraHop apikey={API KEY}" \
"https://{HOST}/api/v1/tags/1"

Finally, when another GET request is sent for that deleted device tag, the operation fails, and a 404 status is returned upon failure, indicating that the tag is no longer available.

curl -i -X GET --header "Accept: application/json" \
--header "Authorization: ExtraHop apikey={API KEY}" \
"https://{HOST}/api/v1/tags/1"

Query the record log

The following request body queries the record log to retrieve 100 HTTP records where the method is GET and the status code is 404.

{
  "filter": {
    "operator": "and",
    "rules": [
        {
            "field": "method",  
            "operand": "GET",
            "operator": "="
        },
        { 
            "field": "statusCode",
            "operand": "404",
            "operator": "="
        }
   ]
 },
 "from": -900000,
 "limit": 100,
 "types": [ 
   "~http" 
 ]
}
