Security

Security isn't a feature you add at the end — it's a set of constraints that shapes how you design, build, and operate systems from the start. A secure system limits what can go wrong, contains the blast radius when something does, and gives you the visibility to detect and respond quickly.

This section covers the operational security practices that sit on top of the foundational concepts in cryptography, authentication-authorization, and networking. Those paradigms explain the what; the articles here explain the how — applied to real infrastructure with real tradeoffs.
