Fix Recommendation

Configure OL 9 to have mail aliases notify the ISSO and SA (at a minimum) in the event of an audit processing failure.

Edit the aliases map file (by default /etc/aliases) used by Postfix and configure a root alias (using the user ISSO as an example):

root: ISSO

Update the aliases database with the command:

$ sudo newaliases

Check Contents

Verify that OL 9 is configured to notify the appropriate interactive users in the event of an audit processing failure.

Find the alias maps that are being used with the following command:

$ postconf alias_maps
alias_maps = hash:/etc/aliases

Query the Postfix alias maps for an alias for the root user with the following command:

$ postmap -q root hash:/etc/aliases
isso

If an alias is not set, this is a finding.
