Your company has a policy that all traffic over public internet should be Post Quantum Cryptography (PQC) ready. Or that for B2B communication Mutual-TLS (mTLS) is mandatory. How do you validate that the policy is correctly implemented?
And check for performance improvements: wat is the ratio of resumed TLS sessions, is the TLS handshake unnecessarily large, is ‘Hello Request’ or is ‘Early Data’ used?
In this session we will cover the methods of analyzing using Wireshark. Even if decryption is not allowed or hard to do.
