The Tanium operating system (TanOS) must provide an immediate real-time alert to the SA and ISSO, at a minimum, of all audit failure events requiring real-time alerts.

An XCCDF Rule

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).
