Abstract
A computer-implemented method and a computer system are provided for selecting active or passive decryption mode when observing network traffic between a downstream client and an upstream server. The method includes selecting a decryption mode in an initial stage of setting up a secure session based on a determination of a most probable decryption mode based on decryption modes used for similar and/or past secure sessions, wherein the initial stage is when the client initiates a transport layer connection before the transport layer connection or the secure session is established. The method further includes validating the selected decryption mode at least once during the secure session based on whether the selected decryption mode is actually and/or is probably supported based on security algorithms supported by the client and/or server, and switching the decryption mode based on a result of validating the selected decryption mode.
