The network element must prevent non-privileged users from circumventing intrusion detection and prevention capabilities.

Description
Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) devices should 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 an IDS 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. When a compromise or potential compromise or breach has been discovered by the intrusion detection system, it is critical the appropriate personnel are notified via an alert mechanism. The intrusion detection device must be configured to ensure non-privileged users are not able to circumvent the detection or alerting mechanisms. This requirement is applicable to network devices such as IDS/IPS and firewalls and is not applicable to the routing function.
