Finding ID	Version	Rule ID	IA Controls	Severity

Description
IDS or IPS must be deployed at strategic locations within the network. At a minimum, they should be deployed within the DMZ and behind the firewall. 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 the firewall function.
