What is OAuth in Cybersecurity?
OAuth is an open authorization framework that lets third-party applications request limited access to a user's resources without exposing their credentials. OAuth 2.0 uses access tokens, scopes, and grant types to define what an application can do on the user's behalf. It handles authorization, not authentication.
Why OAuth Matters for Your Cybersecurity Career
OAuth misconfigurations are a frequent source of web application vulnerabilities. Penetration testers look for open redirect flaws in OAuth flows, token leakage, and insufficient scope restrictions. Security engineers implement OAuth securely in APIs. Understanding the difference between OAuth and OpenID Connect is a common interview topic.
