Fix Recommendation

Configure the audit tools on Ubuntu OS to be protected from unauthorized access by setting the correct permissive mode using the following command:

$ sudo chmod 755 <audit_tool_name>

Replace "<audit_tool_name>" with the audit tool that does not have the correct permissions.

Check Contents

Verify Ubuntu OS configures the audit tools to have a file permission of "755" or less to prevent unauthorized access by using the following command:

$ stat -c "%n %a" /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/audispd* /sbin/augenrules
/sbin/auditctl 755
/sbin/aureport 755
/sbin/ausearch 755
/sbin/autrace 755
/sbin/auditd 755
/sbin/audispd-zos-remote 755
/sbin/augenrules 755

If any of the audit tools have a mode more permissive than "0755", this is a finding.
