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

Description
IDPS sensors 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 firewall. Monitoring outbound traffic enables the network operator to detect an attack towards another network with the local enclave as the base. This is a network architecture design requirement. The network architecture should be designed such that all ingress traffic passes the sensor decrypted and is inspected by the firewall and Network IDPS. This is not an IDPS function.
