Fix Recommendation

To ensure the appropriate flags are enabled for auditing, run the following command:

/usr/bin/sudo sed -i.bak '/^flags/ s/$/,lo/' /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

Attempts to log in as another user are logged by way of the "lo" flag.

If "lo" is not listed in the result of the check, this is a finding.
