In addition to standards compliance, Protocol Anomaly Detection determines whether data within the protocol adheres to expected usage. Even if a communication stream complies with a protocol standard, the way in which the protocol is being used may be inconsistent with what is expected. Perimeter devices that perform protocol anomaly detection contain in-depth knowledge of protocol standards and expected usage and are able to detect traffic that does not comply with those guidelines.
