The Tanium Connect module must be configured to forward Tanium IOC Detect events to identified destinations. (Cat II impact)

Discussion

Indicators of Compromise (IOC) is an artifact that is observed on the network or system that indicates computer intrusion. The Tanium IOC Detect module detects, manages, and analyzes systems against IOCs real-time. The module also responds to those detections. By forwarding events the IOC Detect module, using Tanium Connect with a syslog or SIEM connection, captures the necessary forensic evidence supporting a compromise is retained.
