Discussion

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 Content

Confirm Nutanix AOS preconfigures storage for one week's worth of audit records, when audit records are not immediately sent to a central audit record facility.

$ 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.

Fix Text

As root, modify the /boot/grub/grub.conf file to include the following line:

audit_backlog_limit=8192
