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 profile referenced for the IPsec tunnel to the NOC. interface tunnel-ipsec 30 profile IPSEC_NOC_PROFILE tunnel source GigabitEthernet0/0/0/2 tunnel destination x.1.22.2 Step 2: Note the crypto ACL that was specified in the IPsec profile. crypto isakmp keyring ISAKMP_KEYRING pre-shared-key address x.1.22.2 255.255.255.255 key encrypted 150A13141C32 ! crypto isakmp policy 10 hash sha256 encryption aes 256 authentication pre-share ! crypto ipsec transform-set IPSEC_TRANS esp-aes 256 esp-sha256-hmac mode tunnel ! crypto ipsec profile IPSEC_NOC_PROFILE set pfs group16 match address MGMT_TRAFFIC_ACL Step 3: Review the ACL defined in the crypto map and verify that the destination is the management network. ! ipv4 access-list MGMT_TRAFFIC_ACL 10 permit ipv4 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-17998r991933_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. RP/0/0/CPU0:R3(config)#Ipv4 access-list MGMT_TRAFFIC_ACL RP/0/0/CPU0:R3(config-ipv4-acl)#permit ip 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 Step 2: Create an ISAKMP policy for Phase 1 negotiations. RP/0/0/CPU0:R3(config)#crypto isakmp policy 10 RP/0/0/CPU0:R3(config-isakmp-policy)#authentication pre-share RP/0/0/CPU0:R3(config-isakmp-policy)#hash sha256 RP/0/0/CPU0:R3(config-isakmp-policy)#encryption aes 256 RP/0/0/CPU0:R3(config-isakmp-policy)#exit Step 3: Configure the keyring to be used for ISAKMP to authenticate the remote side during IKE negotiation. RP/0/0/CPU0:R3(config)#crypto isakmp keyring ISAKMP_KEYRING RP/0/0/CPU0:R3(config-crypto-keyring)#pre-shared-key address 255.255.255.255 key xxxxx RP/0/0/CPU0:R3(config-crypto-keyring)#exit Step 4: Configure the IPsec transform set. RP/0/0/CPU0:R3(config)#crypto ipsec transform-set IPSEC_TRANS esp-aes 256 esp-sha256-hmac RP/0/0/CPU0:R3(config-transform-set IPSEC_TRANS)#mode tunnel Step 5: Configure the IPsec profile. RP/0/0/CPU0:R3(config)#crypto ipsec profile IPSEC_NOC_PROFILE RP/0/0/CPU0:R3(config- IPSEC_NOC_PROFILE)#set pfs group 16 RP/0/0/CPU0:R3(config- IPSEC_NOC_PROFILE)#match MGMT_TRAFFIC_ACL transform-set IPSEC_TRANS RP/0/0/CPU0:R3(config- IPSEC_NOC_PROFILE)#exit Step 6: Configure the IPsec virtual interface. RP/0/0/CPU0:R3(config)#interface tunnel-ipsec 22 RP/0/0/CPU0:R3(config-if)#profile IPSEC_NOC_PROFILE RP/0/0/CPU0:R3(config-if)#tunnel source GigabitEthernet0/0/0/2 RP/0/0/CPU0:R3(config-if)#tunnel destination x.1.22.2 RP/0/0/CPU0:R3(config-if)#end
