All encrypted traffic must be decrypted prior to passing through content inspection and filtering mechanisms.

Description
Allowing traffic to bypass the security checkpoints, such as firewalls and intrusion detection systems, puts the network infrastructure and critical data at risk. Malicious traffic could enter the network undetected and attack a key IDPS or the server farm. Hence, it is imperative all encrypted traffic entering the network is decrypted prior to the content checking devices. Encryption and decryption of traffic for filtering is not a function of IDPS. This is a network architecture best practice and does not require a configuration setting in the IDPS components.
