The out-of-band management (OOBM) Arista gateway router must be configured to forward only authorized management traffic to the Network Operations Center (NOC).

Description
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.

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-256023r991786_chk)

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 that the management traffic traverses. Step 1: To verify only management traffic is forwarded through the OOBM interface or IPsec tunnel, execute the command "sh ip access-list". ip access-list OOBM_to_MGMT 10 permit tcp 10.10.10.0/24 host 10.20.10.1 eq ssh telnet 20 permit ip 10.10.10.0/24 192.168.10.0/24 30 permit udp 10.20.20.0/24 any eq bootps snmp Step 2: To verify the ACL is applied outbound on the OOBM interface, execute the command "sh run int Eth YY". interface ethernet 1 description OOBM to MGMT link ip access-group OOBM_to_MGMT out If traffic other than authorized management traffic is permitted through the OOBM interface or IPsec tunnel, this is a finding.

Fix Text (F-59642r882410_fix)

This requirement is not applicable for the DODIN backbone. Configure filters based on port, source IP address, and destination IP address to permit only authorized management traffic into IPsec tunnels or the OOBM interface used for forwarding management data. Step 1: To configure an ACL to allow only management traffic to be forwarded through the OOBM interface or IPsec tunnel, execute the command "sh ip access-list". ip access-list OOBM_to_MGMT 10 permit tcp 10.10.10.0/24 host 10.20.10.1 eq ssh 20 permit ip 10.10.10.0/24 192.168.10.0/24 30 permit udp 10.20.20.0/24 any eq bootps snmp Step 2: To apply the ACL outbound on the OOBM interface, execute the command "sh run int Eth YY". interface ethernet 1 description OOBM to MGMT link ip access-group OOBM_to_MGMT out
