What is Single Sign-On in Cybersecurity?
Single sign-on lets users authenticate once and gain access to multiple applications without re-entering credentials. SSO relies on a central identity provider that issues tokens or assertions to connected service providers. It reduces password fatigue and shrinks the attack surface created by weak or reused passwords.
Why Single Sign-On Matters for Your Cybersecurity Career
SSO is a baseline expectation in enterprise environments. Security engineers integrate SSO across SaaS and on-premises apps. Penetration testers probe SSO configurations for token-replay and session-fixation flaws. Understanding SSO protocols like SAML and OIDC is a practical requirement for most cybersecurity roles.
