Description
The audit service must be configured to create log folders with the correct permissions to prevent normal users from reading audit logs. Audit logs contain sensitive data about the system and about users. If log folders are set to only be readable and writable by root or administrative users with sudo, the risk is mitigated.

Check Text ( C-68045r1_chk )
To check the permissions of the audit log folder, run the following command: /usr/bin/sudo ls -lde $(/usr/bin/sudo /usr/bin/grep '^dir' /etc/security/audit_control | awk -F: '{print $2}') The results should show the permissions (first column) to be "700" or less permissive, if not, this is a finding.

Fix Text (F-73595r1_fix)
For any log folder that returns an incorrect permission value, run the following command: /usr/bin/sudo chmod 700 [audit log folder]
