Which two application layer preprocessors are used by Firepower Next Generation Intrusion PreventionSystem?

Explanation

Application layer protocols can represent the same data in a variety of ways. The Firepower System provides

application layer protocol decoders that normalize specific types of packet data into formats that the intrusion

rules engine can analyze. Normalizing application-layer protocol encodings allows the rules engine to effectively

apply the same content-related rules to packets whose data is represented differently and obtain meaningful

results.
