Fix Recommendation

Configure RHEL 10 to have mail aliases notify the ISSO and SA (at a minimum) 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 following command:

$ sudo newaliases

Check Contents

Verify RHEL 10 is configured to notify the appropriate interactive users of an audit processing failure.

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

$ postconf alias_maps
alias_maps = lmdb:/etc/aliases

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

$ postmap -q root lmdb:/etc/aliases
ISSO

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