6.3.2.5 Ensure the operating system allocates audit record storage capacity

Information

The operating system must allocate audit record storage capacity to store at least one week of audit records, when audit records are not immediately sent to a central audit record storage facility.

To ensure the operating system has a sufficient storage capacity in which to write the audit logs, the operating system needs to 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 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, resize the partition with sufficient space to contain one week of audit records.

If audit records are not stored on a partition made specifically for audit records, a new partition with sufficient space will need be to be created.
