Nutanix OS must configure the audit log files to be owned by root.

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 access to /etc/audit/auditd.conf directory access permissions are set for only authorized users using the following command.

$ sudo ls -al /home/log/audit/audit.log -rw-------. 1 root root 1630962 Oct 12 02:08 /home/log/audit/audit.log

If the audit log is not owned by "root", this is a finding.

Nutanix OS VMs are configured by default to have ownership and permission levels set correctly to meet this requirement. If these are found to be out of compliance, some corruption has taken place and a rebuild of the OS is required.
