Description
To ensure operating systems have a sufficient storage capacity in which to write the audit logs, operating systems must be able to allocate audit record storage capacity. The task of allocating audit record storage capacity is usually performed during initial installation of the operating system.

Check Text (C-279566r1192425_chk)

Verify Nutanix OS preconfigures storage for one week's worth of audit records when audit records are not immediately sent to a central audit record facility using the following command. $ sudo cat /boot/grub/grub.conf | grep audit_backlog_limit audit_backlog_limit=8192 If the "audit_backlog_limit" entry does not equal "8192", is missing, or the line is commented out, this is a finding.
