Manage TDR Incidents

An Incident is a group of indicators related to activity on a specific host. ThreatSync analytics identifies an incident when several indicators with a high threat score are reported for the same host. An incident can contain indicators reported by a Host Sensor, a Firebox, or both.

From the Incidents page, you can see which hosts have the highest severity indicators, and can quickly take action on all the indicators for each host. An incident provides an aggregate view of the indicators on a host.

On the Incidents page in the TDR web UI, you can expand an incident to:

  • See all indicators for that host
  • See which indicators contribute to the incident score (identified by )
  • See the timeline of when each indicator was reported
  • Execute an action to manage threats in an indicator

ThreatSync analytics uses a proprietary set of algorithms to determine a score for each incident based on the scores of the indicators on that host. Only the indicators with critical or high threat scores contribute to the incident score. Indicators with a low threat score are not included in the calculation of incident score. In the incident list for each indicator, identifies that an indicator contributes to the final ThreatSync score for the incident. For more information, see About TDR Threat Scores.

You can also configure policies to automatically complete actions to manage a threat. For more information, see Configure TDR Policies.
