The sequel to Security from Zero (real-life-guide.md). That guide took you
from "what is a byte" to threat-modeling a system, running a PKI, hardening a
host, and breaking and fixing a web app. This one assumes all of that and goes
where real security-engineering work actually lives: the cloud control plane,
Kubernetes, distributed authorization, advanced web and API
exploitation, data-protection and privacy engineering, detection
engineering at scale, and running a security program.
If you have not finished the first guide, stop and do that. This guide will reference its chapters by number (written as G1 Ch 12) and will not re-explain AEAD, TLS handshakes, OAuth flows, STRIDE, or the OWASP Top 10.
