Check: CISC-L2-000070
Cisco IOS XE Switch L2S STIG:
CISC-L2-000070
(in versions v2 r2 through v1 r0.1)
Title
The Cisco switch must be configured to provide the capability for authorized users to remotely view, in real time, all content related to an established user session from a component separate from the Cisco switch. (Cat II impact)
Discussion
Without the capability to remotely view/hear all content related to a user session, investigations into suspicious user activity would be hampered. Real-time monitoring allows authorized personnel to take action before additional damage is done. The ability to observe user sessions as they are happening allows for interceding in ongoing events that after-the-fact review of captured content would not allow.
Check Content
Verify that the switch is capable of capturing ingress and egress packets from any designated switch port for the purpose of remotely monitoring a specific user session. The example configuration below will capture packets from interface GigabitEthernet0/3 and replicate the packets to interface GigabitEthernet0/2. monitor session 1 source interface Gi0/3 monitor session 1 destination interface Gi0/2 If the switch is not capable of capturing ingress and egress packets from a designated switch port for the purpose of remotely monitoring a specific user session, this is a finding.
Fix Text
Enable the feature or configure the switch so that it is capable of capturing ingress and egress packets from any designated switch port for the purpose of monitoring a specific user session. The example configuration below will capture packets from interface GigabitEthernet0/3 and replicate the packets to GigabitEthernet0/2. SW1(config)#monitor session 1 source int g0/3 SW1(config)#monitor session 1 destination int g0/2
