Introduction
There's a moment in every security review where you stop looking at the code and start asking a much older question: can I trust this? Trust who someone claims to be, and trust what a piece of software or data claims to be. That's really the throughline connecting OWASP's A07 and A08 categories.
A07: Authentication Failures asks whether an application can reliably verify who a user is — not just at login, but for as long as that user's session exists.
A08: Software and Data Integrity Failures asks a different but related question: can the application trust the software and data it receives before it acts on them?
