Discussion

Protecting audit information also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on audit information. Operating systems providing tools to interface with audit information will leverage user permissions and roles identifying the user accessing the tools and the corresponding rights the user enjoys to make access decisions regarding the access to audit tools. Audit tools include, but are not limited to, vendor-provided and open source audit tools needed to successfully view and manipulate audit information system activity and records. Audit tools include custom queries and report generators.

Verify Ubuntu OS configures the audit tools to be owned by "root" to prevent any unauthorized access with the following command:  
  
     $ stat -c "%n %U" /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/audispd* /sbin/augenrules 
     /sbin/auditctl root 
     /sbin/aureport root 
     /sbin/ausearch root 
     /sbin/autrace root 
     /sbin/auditd root 
     /sbin/audispd-zos-remote root 
     /sbin/augenrules root 
 
If any of the audit tools are not owned by "root", this is a finding.
