Discussion

If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users. Installation of IPS detection and prevention components (i.e., sensors) at key boundaries in the architecture mitigates the risk of DoS attacks. These attacks can be detected by matching observed communications traffic with patterns of known attacks. Detection components that use anomaly-based attack detection can detect attacks when signatures for the attack do not exist or are not installed. These attacks include zero-day attacks, new attacks for which vendors have not yet developed signatures. This requirement applies to the communications traffic functionality of the IPS as it pertains to handling communications traffic, rather than to the IPS device itself.

If the device being reviewed is an IDS, this is not applicable.

Verify the IPS protect against or limits the effects of known and unknown types of DoS attacks by employing, also known as anomaly-based detection.

If the device does not protect against or limit the effects of known and unknown types of DoS attacks by employing anomaly-based detection, this is a finding.
