In spite of the fact that SSL/TLS is omnipresent in todays Internet commerce, it is highly vulnerable to man-in-the-middle (MITM) attacks. In this talk, we explain why this is the case and what possibilities one has at hand to protect SSL/TLS-secured Internet commerce against MITM attacks. In particular, we introduce, discuss, and put into perspective a technology called SSL/TLS session-aware (TLS-SA) user authentication that basically links a user authentication to a particular SSL/TLS session to reveal the existence of an MITM. The technology does not protect against malware taking control after user authentication (a so-called man-in-the-browser attack). So TLS-SA does not stop the general trend towards transaction authentication in addition to user authentication for applications with high security requirements, such as Internet banking.
