Title

The AIX audit configuration files must be group-owned by audit. (Cat II impact)

Discussion

Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent the auditing of critical events. Misconfigured audits may degrade the system's performance by overwhelming the audit log. Misconfigured audits may also make it more difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

Check Content

Check that all the audit configuration files under /etc/security/audit/* have group ownership. # ls -l /etc/security/audit/* -rw-r----- 1 root audit 37 Oct 10 2016 /etc/security/audit/bincmds -rw-r----- 1 root audit 2838 Sep 05 16:33 /etc/security/audit/config -rw-r----- 1 root audit 26793 Oct 10 2016 /etc/security/audit/events -rw-r----- 1 root audit 340 Oct 10 2016 /etc/security/audit/objects -rw-r----- 1 root audit 54 Oct 10 2016 /etc/security/audit/streamcmds If any file's group ownership is not "audit", this is a finding.

Fix Text

Set the group of the audit configuration files to "audit". # chgrp audit /etc/security/audit/*
