Migrate tuning rules

1. Retrieve the tuning rule metadata from the source system.
   1. 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/.
   2. Click Enter API Key and then paste or type your API key into the API Key field.
   3. Click Authorize and then click Close.
   4. Click Detections.
   5. Click GET ​/detections​/rules​/hiding.
   6. Click Try it out.
   7. Click Send Request.
   8. In the Response body field, copy the JSON object that represents the tuning rule you want to copy.
2. Recreate the tuning rule on the target system.
   1. In a browser, navigate to the REST API Explorer.
   2. Click Enter API Key and then paste or type your API key into the API Key field.
   3. Click Authorize and then click Close.
   4. Click Detections.
   5. Click POST ​/detections​/rules​/hiding.
   6. Click Try it out.
   7. In the body text box, paste the JSON object you copied from the source sensor or console.

      The entry should look similar to the following text:

      {
          "id": 1,
          "enabled": false,
          "detection_type": "cifs_round_trip_time",
          "offender": {
            "object_type": "device",
            "object_id": 123
          },
          "victim": {
            "object_type": "device",
            "object_id": 321
          },
          "author": "example_user",
          "create_time": 1615588932838,
          "expiration": 1615675096000,
          "detections_hidden": 0
      }

      Copy

      Note:

      If the description or properties field is set to null null, you must remove those fields from the JSON before sending the request.

   8. Click Send Request.
3. (Optional): Disable the tuning rule on the target system.

   If the tuning rule was disabled on the source system, indicated by the enabled field set to false, set the enabled field to false on the target system.

   1. In a browser, navigate to the REST API Explorer.
   2. Click Enter API Key and then paste or type your API key into the API Key field.
   3. Click Authorize and then click Close.
   4. Click Detections.
   5. Click PATCH ​/detections​/rules​/hiding.
   6. Click Try it out.
   7. In the body text box, paste the following JSON:

      {
          "enabled": false
      }

      Copy
   8. Click Send Request.

The ExtraHop GitHub repository contains an example Python script that migrates all tuning rules on an ECA VM to Reveal(x) 360.

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

   SOURCE_HOST: The hostname of the ECA VM you are migrating tuning rules from

   SOURCE_API_KEY: The API KEY on the ECA VM you are migrating tuning rules from

   TARGET_HOST: The hostname of the Reveal(x) 360 API you are migrating tuning rules to. This hostname is displayed in the Reveal(x) 360 API Access page under API Endpoint. The hostname does not include the /oauth/token.

   TARGET_ID: The ID of the REST API credentials for Reveal(x) 360

   TARGET_SECRET: The secret of the REST API credentials for Reveal(x) 360

3. Run the following command:

   python3 migrate_detection_hiding.py

   Copy

   If tuning rules specify participant devices or device groups by an ID, the script tries to find the IDs of equivalent participants on Reveal(x) 360 by searching for device IP addresses and device group names.

   If the script cannot find the IDs for equivalent participants on Reveal(x) 360, the script prompts you to migrate the other rules that equivalent participants were found for. To continue, type y and press ENTER.

   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) Copy
