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

An XCCDF Rule

Description

<VulnDiscussion>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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

This requirement is not applicable for the DoDIN Backbone.

Configure filters 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
[edit firewall family inet]set filter MGMT_TRAFFIC term ALLOW_SNMP from protocol udp port [snmp snmptrap]
set filter MGMT_TRAFFIC term ALLOW_SNMP then accept
set filter MGMT_TRAFFIC term ALLOW_TACACS from protocol tcp port tacacs
set filter MGMT_TRAFFIC term ALLOW_TACACS then accept
set filter MGMT_TRAFFIC term ALLOW_NETFLOW from protocol udp port [2055 9995 9996]
set filter MGMT_TRAFFIC term ALLOW_NETFLOW then accept
set filter MGMT_TRAFFIC term DENY_OTHER then syslog discard

[edit interfaces ge-1/1/0  unit 0 family inet]
set filter output MGMT_TRAFFIC

IPsec Tunnel
