The network device must ensure all encrypted traffic is visible to network monitoring tools.

Description
Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) devices should be deployed at strategic locations within the network. At a minimum, they should be deployed within the DMZ and behind the network device. It is important to not only monitor traffic entering the enclave but also leaving. Placing an IDS behind the network device will provide a clear analysis of what type of traffic and potential attacks are passing through the network device. Monitoring outbound traffic enables the network operator to detect an attack towards another network with the local enclave as the base. Regardless of direction, all encrypted traffic must be decrypted prior to reaching the network device so all traffic can be monitored. This control applies to monitoring by intrusion detection systems and is not applicable to network device management.
