Descripción

The /var/adm/sa directory holds the performance data produced by the sar utility. The /var/adm/sa directory contains the report files produced by the sar utility. This directory must be secured from unauthorized access. Audit: compares `ls -ld` mode (this mode or more restrictive), owner and group with the CIS values; ACLs are not evaluated.
