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:

R4(config)#ip access-list extended MGMT_TRAFFIC_ACL
R4(config-ext-nacl)#permit tcp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq tacacs
R4(config-ext-nacl)#permit tcp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq 22
R4(config-ext-nacl)#permit udp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq snmp
R4(config-ext-nacl)#permit udp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq snmp-trap
R4(config-ext-nacl)#permit udp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq syslog
R4(config-ext-nacl)#permit icmp 10.1.34.0 0.0.0.255 10.22.22.0 0.0.0.255 echo
R4(config-ext-nacl)#permit icmp 10.1.34.0 0.0.0.255 10.22.22.0 0.0.0.255 echo-reply
R4(config-ext-nacl)#deny ip any any log-input
R4(config-ext-nacl)#exit

IPsec Tunnel:

R4(config)#ip access-list extended MGMT_TRAFFIC_ACL
R4(config-ext-nacl)#permit tcp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq tacacs
R4(config-ext-nacl)#permit tcp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq 22
R4(config-ext-nacl)#permit udp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq snmp
R4(config-ext-nacl)#permit udp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq snmp-trap
R4(config-ext-nacl)#permit udp 10.1.34.0 0.0.0.255 10.22.2.0 0.0.0.255 eq syslog
R4(config-ext-nacl)#permit icmp 10.1.34.0 0.0.0.255 22.22.22.0 0.0.0.255
R4(config-ext-nacl)#exit
