The Tanium application must provide an immediate real-time alert to the system administrator and information system security officer, at a minimum, of all audit failure events requiring real-time alerts.


Overview

Finding ID Version Rule ID IA Controls Severity
V-253794 TANS-00-001320 SV-253794r850195_rule Medium
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).
