Title
The Cisco router must be configured to allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.
Control
Verify that the Cisco router is configured with a logging buffer size. The configuration should look like the example below: logging buffered xxxxxxxx informational If a logging buffer size is not configured, this is a finding. If the Cisco router is not configured to allocate audit record storage capacity in accordance with organization-defined audit record storage requirements, this is a finding.
Discussion
In order to ensure network devices have a sufficient storage capacity in which to write the audit logs, they need to be able to allocate audit record storage capacity. The task of allocating audit record storage capacity is usually performed during initial device setup if it is modifiable. The value for the organization-defined audit record storage requirement will depend on the amount of storage available on the network device, the anticipated volume of logs, the frequency of transfer from the network device to centralized log servers, and other factors.
