Information
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.
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
Allocate enough storage capacity for at least one week's worth of audit records when audit records are not immediately sent to a central audit record storage facility.
If audit records are stored on a partition made specifically for audit records, use the "parted" program to resize the partition with sufficient space to contain one week's worth of audit records.
If audit records are not stored on a partition made specifically for audit records, a new partition with sufficient amount of space will need be to be created.
Set the auditd server to point to the mount point where the audit records must be located:
$ sudo sed -i -E 's@^(log_files*=s*).*@1 <audit_partition_mountpoint>/audit.log@' /etc/audit/auditd.conf
where <audit_partition_mountpoint> is the aforementioned mount point.
