Fix Recommendation

To set the audit flags to the recommended setting, run the following command to add the flags "fm", "-fr", and "-fw" all at once:

/usr/bin/sudo /usr/bin/sed -i.bak '/^flags/ s/$/,fm,-fr,-fw/' /etc/security/audit_control; /usr/bin/sudo /usr/sbin/audit -s

A text editor may also be used to implement the required updates to the "/etc/security/audit_control" file.

Check Contents

To view the currently configured flags for the audit daemon, run the following command:

/usr/bin/sudo /usr/bin/grep ^flags /etc/security/audit_control

Enforcement actions are logged by way of the "fm" flag, which audits permission changes, and "-fr" and "-fw", which denote failed attempts to read or write to a file.

If "fm", "-fr", and "-fw" are not listed in the result of the check, this is a finding.
