Discussion

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

Check Content

To check the ownership of the audit log files, run the following command:

/usr/bin/sudo ls -le $(/usr/bin/sudo /usr/bin/grep '^dir' /etc/security/audit_control | awk -F: '{print $2}') | grep -v current

The results should show the owner (third column) to be "root". 

If they do not, this is a finding.
