The path so far (2 books)
Why read this first: Authentication, sessions, and cookies all sit on top of HTTP. Grasping HTTP's behavior from first principles first lets you understand structurally where in the protocol the vulnerabilities in Tokumaru's book actually arise.
Why read this first: After grasping the overall picture of vulnerability defense, descend to the cryptographic foundation that much of it relies on. Understanding the logic of hashing, signatures, and public-key crypto lets you treat TLS and token verification as principles rather than magic.
