A few years ago, moving away from the Implicit OAuth flow to the Auth code with PKCE shield was enough to protect our kingdoms. But as attackers have sharpened their blades, our defenses must evolve beyond the basics. This quest begins with the foundations of secure coding: implementing methodologies to thwart XSS incursions, such as a robust Content Security Policy (CSP) with Angular's built-in CSP nonce. From there, we’ll layer our protection with modern OAuth armaments designed to harden our identity flows and fortify the castle's architecture against token theft. Join this session to learn how to build a truly hardened fortress for the modern age.
