Title

The RUCKUS ICX router must implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions. (Cat II impact)

Discussion

Separating critical system components and functions from other noncritical system components and functions through separate subnetworks may be necessary to reduce susceptibility to a catastrophic or debilitating breach or compromise that results in system failure. For example, physically separating the command and control function from the in-flight entertainment function through separate subnetworks in a commercial aircraft provides an increased level of assurance in the trustworthiness of critical system functions.

Check Content

Verify the router is configured to implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions. If the router is not configured to implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions, this is a finding.

Fix Text

Configure the router to implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions. Configure VLANs separate organization-defined traffic: device# configure terminal device(config)# vlan 235 name mgmt-vlan device(config-vlan-235)# tag ethernet 1/x/x device(config-vlan-235)# interface ve 235 device(config-vif-235)# ip addr x.x.x.x/x device(config-vif-235)# vlan 200 name ops-vlan device(config-vlan-200)# tag ethernet 1/x/x device(config-vlan-200)# interface ve 200 device(config-vif-200)# ip addr x.x.x.x/x device(config-vif-200)# vlan 210 name user-vlan device(config-vlan-210)# tag ethernet 1/x/x device(config-vlan-210)# interface ve 210 device(config-vif-210)# ip addr x.x.x.x/x device(config-vif-210)#end device# write memory
