The network element must interconnect and configure individual intrusion detection tools into a system-wide intrusion detection system using common protocols.

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. It is important to not only monitor traffic entering the enclave but also leaving. Placing a sensor behind the firewall will provide a clear analysis of what type of traffic and potential attacks are passing through the device. Monitoring outbound traffic enables the network operator to detect an attack towards another network with the local enclave as the base. This control applies to monitoring by intrusion detection systems and is not applicable to the firewall function.
