The Cisco out-of-band management (OOBM) gateway router must be configured to transport management traffic to the Network Operations Center (NOC) via dedicated circuit, MPLS/VPN service, or IPsec tunnel.

Description
Using dedicated paths, the OOBM backbone connects the OOBM gateway routers located at the edge of the managed network and at the NOC. Dedicated links can be deployed using provisioned circuits or MPLS Layer 2 and Layer 3 VPN services or implementing a secured path with gateway-to-gateway IPsec tunnels. The tunnel mode ensures that the management traffic will be logically separated from any other traffic traversing the same path.

Who does this work

15 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

This requirement is not applicable for the DODIN Backbone. Review the network topology diagram to determine connectivity between the managed network and the NOC. Review the OOBM gateway router configuration to validate the path and interface that the management traffic traverses. If an IPsec tunnel is used to transport the management traffic between the NOC and the managed network, review the configuration following the steps below. Step 1: Note the crypto map applied to the external interface. interface interface GigabitEthernet0/2 description link to DISN ip address x.1.24.4 255.255.255.0 crypto map IPSEC_MGMT_MAP Step 2: Review the ISAKMP policy for Phase 1 negotiations and Phase 2 policy for data encryption. crypto isakmp policy 10 authentication pre-share hash sha256 crypto isakmp key xxxxxx address x.1.12.1 ! ! crypto IPsec transform-set TRANS_SET ah-sha256-hmac esp-aes Step 3: Review the crypto map that was bound to the external interface and note the ACL defined that identifies the interesting traffic for the IPsec tunnel. crypto map IPSEC_MGMT_MAP 10 ipsec-isakmp set peer x.1.12.1 set transform-set TRANS_SET match address MGMT_TRAFFIC_ACL Step 4: Review the ACL defined in the crypto map and verify that the destination is the management network. ip access-list extended MGMT_TRAFFIC_ACL permit ip 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 Note: The management network is this example is 10.22.2.0/24 If management traffic is not transported between the managed network and the NOC via dedicated circuit, MPLS/VPN service, or IPsec tunnel, this is a finding.

Fix Text (F-17819r991837_fix)

This requirement is not applicable for the DODIN Backbone. Ensure that a dedicated circuit, MPLS/VPN service, or IPsec tunnel is deployed to transport management traffic between the managed network and the NOC. If an IPsec tunnel is to be used, the steps below can be used as a guideline. Step 1: Configure the ACL for the management network as the destination. This ACL will be defined in the crypto as the interesting traffic to be forwarded into the IPsec tunnel. R4(config)#ip access-list extended MGMT_TRAFFIC_ACL R4(config-ext-nacl)#permit ip 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 R4(config-ext-nacl)#exit Step 2: Create an ISAKMP policy for Phase 1 negotiations. R4(config)#crypto isakmp policy 10 R4(config-isakmp)#hash sha256 R4(config-isakmp)#authentication pre-share R4(config-isakmp)#exit Step 3: Specify the pre-shared key and the remote peer address. R4(config)#crypto isakmp key 0 xxxxxx address x.1.12.1 Note: Digital certificates can be utilized as an alternative. Step 4: Create the IPSec transform set for the data encryption R4(config)#crypto ipsec transform-set TRANS_SET ah-sha256-hmac esp-aes R4(cfg-crypto-trans)#mode tunnel R4(cfg-crypto-trans)#exit Step 5: Create the crypto map.
