Check Contents

1. Verify Nutanix OS is set to notify the SA and ISSO in the event of an audit processing failure using the following command.

$ sudo grep action_mail_acct /etc/audit/auditd.conf
action_mail_acct = root

If "action_mail_acct" is not set to "root" or the keyword is missing, this is a finding.

2. Verify Nutanix OS is set to notify administrators in the event of an auditing processing failure using the following command.

$ sudo grep -i "postmaster:\s*root$" /etc/aliases
postmaster: root

If the command does not return a line, or is commented out, this is a finding.
