CISC-RT-000410 - The Cisco out-of-band management (OOBM) gateway router must be configured to forward only authorized management traffic to the Network Operations Center (NOC).
Information
The OOBM network is an IP network used exclusively for the transport of OAM&P data from the network being managed to the OSS components located at the NOC. Its design provides connectivity to each managed network device, enabling network management traffic to flow between the managed network elements and the NOC. This allows the use of paths separate from those used by the managed network.NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
This requirement is not applicable for the DODIN Backbone.Configure ACLs to permit only authorized management traffic into IPsec tunnels or the OOBM interface used for forwarding management data as shown in the examples below:
OOBM Link:
