TLS 1.3, standardized in 2018, is a substantial security and performance redesign over TLS 1.2, removing an entire category of legacy cryptographic options that had accumulated known weaknesses over two decades, and cutting the handshake to a single round trip. Yet even a server correctly configured for TLS 1.3 can still be misconfigured in ways that quietly undermine its protection — supporting older protocol versions for compatibility, choosing weak cipher suites, or misconfiguring certificate validation are common findings even on modern deployments.

💪 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.
