SSO: Single Sign-On in Cybersecurity
SSO stands for Single Sign-On. Single sign-on lets users authenticate once and access multiple applications without re-entering credentials. SSO relies on a central identity provider that issues tokens or assertions to connected services.
How SSO Is Used in Cybersecurity
Security engineers integrate SSO across SaaS and on-premises applications to reduce password sprawl. Penetration testers probe SSO configurations for token replay and session fixation flaws. Architects choose between SAML and OIDC based on application requirements.
