OIDC: OpenID Connect in Cybersecurity
OIDC stands for OpenID Connect. OpenID Connect is an identity layer built on top of OAuth 2.0 that lets clients verify user identity and obtain basic profile information. OIDC uses JSON Web Tokens for identity assertions.
How OIDC Is Used in Cybersecurity
Security engineers implement OIDC flows for web and mobile application authentication. Penetration testers test for token leakage, redirect URI manipulation, and improper scope validation. OIDC has become the preferred protocol for modern SSO because of its simplicity compared to SAML.
