Discussion

If audit information were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity of audit information, the operating system must protect audit information from unauthorized deletion. This requirement can be achieved through multiple methods, which will depend upon system architecture and design. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit information system activity.

Verify that the audit log directory has a mode of "0750" or less permissive. 
 
Determine where the audit logs are stored with the following command: 
 
$ sudo grep -iw ^log_file /etc/audit/auditd.conf 
log_file = /var/log/audit/audit.log 
 
Using the path of the directory containing the audit logs, determine if the directory has a mode of "0750" or less by using the following command: 
 
$ sudo stat -c "%n %a" /var/log/audit /var/log/audit/* 
/var/log/audit 750 
/var/log/audit/audit.log 600 
 
If the audit log directory has a mode more permissive than "0750", this is a finding.
