The Tanium enterprise audit log reduction option must be configured to provide alerts based off Tanium audit data.


Overview

Finding ID Version Rule ID IA Controls Severity

Description
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).
