Fix Recommendation

Configure the files in directory "/etc/audit/rules.d/" and the "/etc/audit/auditd.conf" file to have a mode of "0640" with the following commands:

$ sudo chmod 0640 /etc/audit/rules.d/audit.rules
$ sudo chmod 0640 /etc/audit/rules.d/[customrulesfile].rules
$ sudo chmod 0640 /etc/audit/auditd.conf

Check Contents

Verify that the files in directory "/etc/audit/rules.d/" and "/etc/audit/auditd.conf" file have a mode of "0640" or less permissive by using the following commands:

$ sudo ls -l /etc/audit/rules.d

-rw-r----- 1 root root 1280 Feb 16 17:09 audit.rules

$ sudo ls -l /etc/audit/auditd.conf

-rw-r----- 1 root root 621 Sep 22 17:19 auditd.conf

If the files in the "/etc/audit/rules.d/" directory or the "/etc/audit/auditd.conf" file have a mode more permissive than "0640", this is a finding.
