CISR-ND-000097
(in versions v1 r5 through v1 r4)
Title
The Cisco IOS XE router must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements. (Cat II impact)
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.
Check Content
Verify that the Cisco IOS XE router is configured with a logging buffer size. The configuration should look like the example below: logging buffered 4096 If a logging buffer size is not configured, this is a finding.
Fix Text
Add the following command to configure a buffer size (The range is 4096 to 2147483647 in bytes). logging buffered 4096
