The RUCKUS ICX out-of-band management (OOBM) gateway router must be configured to block any traffic destined to itself that is not sourced from the OOBM network or the Network Operations Center (NOC).

Description
If the gateway router is not a dedicated device for the OOBM network, several safeguards must be implemented for containment of management and production traffic boundaries. It is imperative that hosts from the managed network are not able to access the OOBM gateway router.

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.

Check Text (C-273615r1111064_chk)

This requirement is not applicable for the DODIN Backbone. Verify traffic destined to itself is only sourced by the OOBM or the NOC. In the example below, the OOBM backbone network is 10.11.1.0/24, the NOC address spaces is 10.12.1.0/24, and the OOBM LAN address space at remote site connecting to the managed network is 10.13.1.0/24. 1. Note the inbound ACL applied to the OOBM interfaces. interface ethernet 1/2/1 port-name OOBM-to-NOC ip address 10.11.1.8 255.255.255.0 ip access-group TRAFFIC_FROM_NOC in logging enable ! interface ethernet 1/2/2 port-name OOBM_LAN_ACCESS_SWITCH ip address 10.13.1.1 255.255.255.0 ip access-group TRAFFIC_TO_NOC in logging enable 2. Review the inbound ACL bound to any OOB interface connecting to the OOBM backbone and verify traffic destined to itself is only from the OOBM or NOC address space. ip access-list extended TRAFFIC_FROM_NOC sequence 10 permit ip 10.11.1.0 0.0.0.255 host 10.11.1.8 sequence 20 permit ip 10.12.1.0 0.0.0.255 host 10.11.1.8 sequence 30 permit ip 10.11.1.0 0.0.0.255 host 10.13.1.1 sequence 40 permit ip 10.12.1.0 0.0.0.255 host 10.13.1.1 sequence 50 deny ip any host 10.11.1.8 log sequence 60 deny ip any host 10.13.1.1 log sequence 70 permit ip 10.11.1.0 0.0.0.255 10.13.1.0 0.0.0.255 sequence 80 permit ip 10.12.1.0 0.0.0.255 10.13.1.0 0.0.0.255 sequence 90 deny ip any any log ! 3. Review the inbound ACL bound to any OOBM LAN interfaces and verify traffic destined to itself is from the OOBM LAN address space. ip access-list extended TRAFFIC_TO_NOC sequence 10 permit ip 10.13.1.0 0.0.0.255 host 10.13.1.1 sequence 20 permit ip 10.13.1.0 0.0.0.255 host 10.11.1.8 sequence 30 deny ip any host 10.13.1.1 log sequence 40 deny ip any host 10.11.1.8 log sequence 50 permit ip 10.13.1.0 0.0.0.255 10.11.1.0 0.0.0.255 sequence 60 permit ip 10.13.1.0 0.0.0.255 10.12.1.0 0.0.0.255 sequence 70 deny ip any any log ! If the router does not block any traffic destined to itself that is not sourced from the OOBM network or the NOC, this is a finding.

This requirement is not applicable for the DODIN Backbone. Configure traffic from the managed network to not be able to access the OOBM gateway router using either receive path or interface ingress ACLs. 1. Configure the ACL to only allow traffic to the route processor from the OOBM backbone and the NOC. ICX(config)#ip access ext TRAFFIC_FROM_NOC ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#permit ip 10.11.1.0/24 host 10.11.1.8 ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#permit ip 10.12.1.0/24 host 10.11.1.8 ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#permit ip 10.11.1.0/24 host 10.13.1.1 ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#permit ip 10.12.1.0/24 host 10.13.1.1 ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#deny ip any host 10.11.1.8 log ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#deny ip any host 10.13.1.1 log ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#permit ip 10.11.1.0/24 10.13.1.0/24 ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#permit ip 10.12.1.0/24 10.13.1.0/24 ICX(config-ext-ipacl-TRAFFIC_FROM_NOC)#deny ip any any log 2. Configure the ACL to only allow traffic to the route processor from the OOBM LAN. ICX(config)#ip access ext TRAFFIC_TO_NOC ICX(config-ext-ipacl-TRAFFIC_TO_NOC)#permit ip 10.13.1.0/24 host 10.13.1.1 ICX(config-ext-ipacl-TRAFFIC_TO_NOC)#permit ip 10.13.1.0/24 host 10.11.1.8 ICX(config-ext-ipacl-TRAFFIC_TO_NOC)#deny ip any host 10.13.1.1 log ICX(config-ext-ipacl-TRAFFIC_TO_NOC)#deny ip any host 10.11.1.8 log ICX(config-ext-ipacl-TRAFFIC_TO_NOC)#permit ip 10.13.1.0/24 10.11.1.0/24 ICX(config-ext-ipacl-TRAFFIC_TO_NOC)#permit ip 10.13.1.0/24 10.12.1.0/24 ICX(config-ext-ipacl-TRAFFIC_TO_NOC)#deny ip any any log 3.
