Even in these modern times, we still trade credentials for authentication or session tokens. In typical applications, session tokens received on the client side are stored in either the browser's local storage or as cookies. As an attacker, I want to steal a user's auth token, hijack their session and then take over their account. The browser and a naive user are good attack vectors. We’ll run through how to architect your website to take advantage of various browser-based protections that reduce the impact of common attacks, such as cross-site scripting and privilege escalation.
