The network device must analyze outbound communications traffic at selected interior points within the network as deemed necessary to discover anomalies.

Description
Sensors must be deployed at strategic locations within the network. At a minimum, they must 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 a sensor 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. Monitoring outbound traffic can also detect abnormal traffic or mischievous activities by internal personnel. This control applies to monitoring by intrusion detection systems and is not applicable to network device management.
