This exercise applies Module 5's concepts to a working demo login flow: adding TOTP-based multi-factor authentication, hardening session cookies with the correct security attributes, and regenerating the session token on login to defend against fixation. By the end, the demo app's authentication flow will reflect the same baseline hardening a real production login system is expected to have.

💪 Think of it like fitness: injuries follow a predictable chain — poor warm-up, then form breakdown, then compensation, then the actual tear — and a good physio catalogs where each patient's chain can be interrupted early, rather than only treating the tear afterward. MITRE ATT&CK is the sports-medicine literature of intrusions: a public catalog of every observed breakdown pattern, organized by the stage it serves — how attackers get in, how they escalate, how they extract. Coaches worldwide describe an athlete's risk in that shared vocabulary. This reveals ATT&CK's real value: intrusions become a sequence you can interrupt at stage two, not a disaster you discover at stage five.
