The network device must monitor inbound and outbound communications for unusual or unauthorized activities or conditions.

Finding ID	Version	Rule ID	IA Controls	Severity

Description
Intrusion Detection Systems (IDSs) or Intrusion Prevention Systems (IPSs) must be deployed at strategic locations within the network. At a minimum, they should be deployed within the DMZ and behind 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. Without monitoring of both outbound and inbound traffic for anomalies, critical indicators of attacks may be missed until it is too late. This control applies to monitoring by intrusion detection systems and is not applicable to network device management.
