After you deploy the ExtraHop Trace appliance, log into the Admin UI and configure the following settings. Refer to the section of the ExtraHop Trace Admin UI Guide specified in each action below, except where noted.
- Maintain system security after the evaluation period. Change the default password. For more information, see the Change Password section.
- Time is critical in the Trace appliance, particularly when doing event correlation with time-based metrics and logs. Verify that the NTP settings are correct for your infrastructure, test settings, and sync NTP. For more information, see the System Time section.
- Time Zone
- The correct time zone is critical to run scheduled reports at the correct time. Ensure the Trace appliance has the correct time zone. For more information, see the System Time section.
- Remote Authentication
- Set up remote authentication. The Trace appliance integrates with RADIUS, TACACS, and LDAP for remote integration. For more information, see the Remote Authentication section.
- Firmware Update
- Trace appliance firmware is updated often with enhancements and resolved defects. Verify that you have the current firmware. For more information, see the Firmware section.
- Audit Logging
- The Trace appliance can send events to a remote syslog collector. Configure the Trace appliance to send audit logs. For more information, see the Audit Log section.
- The Trace appliance can email alerts and system-health notifications. Set up and test notifications. For more information, see the Email Server and Sender section.
- System Notifications
- The Trace appliance can send email notifications if disk errors are detected. Add email addresses to receive disk notifications. For more information, see the Notifications section.
- Each physical Trace appliance has an iDRAC port, similar to iLO or KVM over Ethernet. Connect and configure the iDRAC port. For more information, see Configuring the iDRAC Remote Access Console.
- SSL Certificate
- Each Trace appliance ships with a self-signed certificate. If you have a PKI deployment, generate your own certificate and upload it to each Trace appliance. For more information, see the SSL Certificate section.
- DNS A Record
- It is easier to access an Trace appliance by hostname than by IP address. Create an A record in your DNS root ("eta.yourdomain.local") for each Trace appliance in your deployment. Refer to your DNS administration manual.
