Fix Recommendation

Configure the audit tools on the Ubuntu operating system to be protected from unauthorized access by setting the file owner as root using the following command:

$ sudo chown root [audit_tool]

Replace "[audit_tool]" with each audit tool not owned by root.

Check Contents

Verify the Ubuntu operating system configures the audit tools to be owned by root to prevent any unauthorized access.

Check the ownership by running the following command:

$ stat -c "%n %U" /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/audispd /sbin/augenrules

/sbin/auditctl root
/sbin/aureport root
/sbin/ausearch root
/sbin/autrace root
/sbin/auditd root
/sbin/audispd root
/sbin/augenrules root

If any of the audit tools are not owned by root, this is a finding.
