Fix Recommendation

Configure the auditd service to notify the administrators in the event of a SUSE operating system audit processing failure.

Configure an alias value for the postmaster with the following command:

> sudo sh -c 'echo "postmaster: root" >> /etc/aliases'

Configure an alias for root that forwards to a monitored email address with the following command:

> sudo sh -c 'echo "root: box@server.mil" >> /etc/aliases'

The following command must be run to implement changes to the /etc/aliases file:

> sudo newaliases

Check Contents

Verify the administrators are notified in the event of a SUSE operating system audit processing failure by checking that "/etc/aliases" has a defined value for root.

> grep -i "^postmaster:" /etc/aliases

postmaster: root

If the above command does not return a value of "root", or the output is commented out, this is a finding

Verify the alias for root forwards to a monitored e-mail account:

> grep -i "^root:" /etc/aliases
root: person@server.mil

If the alias for root does not forward to a monitored e-mail account, or the output is commented out, this is a finding.
