Check: CISC-L2-000060
Cisco NX OS Switch L2S STIG:
CISC-L2-000060
(in versions v2 r3 through v1 r0.1)
Title
The Cisco switch must be configured for authorized users to select a user session to capture. (Cat II impact)
Discussion
Without the capability to select a user session to capture/record or view/hear, investigations into suspicious or harmful events would be hampered by the volume of information captured. The volume of information captured may also adversely impact the operation for the network. Session audits may include port mirroring, tracking websites visited, and recording information and/or file transfers.
Check Content
Verify that the switch 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 Ethernet1/66 and replicate the packets to interface Ethernet1/68. monitor session 1 source interface Ethernet1/66 both destination interface Ethernet1/68 If the switch is not capable of capturing ingress and egress packets from a designated switch port, 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 Ethernet1/66 and replicate the packets to Ethernet1/68. SW1(config)# monitor session 1 SW1(config-monitor)# source interface ethernet 1/66 SW1(config-monitor)# destination interface ethernet 1/68 SW1(config-monitor)# end
