Overview

Finding ID Version Rule ID IA Controls Severity
V-22599 GEN000000-SOL00110 SV-27004r1_rule ECLP-1 Medium
Description
Audit_user is a sensitive file that, if compromised, would allow a malicious user to select auditing parameters to ignore their sessions. This would allow malicious operations the auditing subsystem would not detect for that user. It could also result in long-term system compromise possibly leading to the compromise of other systems and networks.
