What is SAML in Cybersecurity?
Two syllables, like the name 'Sam' plus 'el'.
SAML (Security Assertion Markup Language) is an XML-based standard for exchanging authentication and authorization data between an identity provider and a service provider. It enables browser-based single sign-on by passing signed assertions. SAML 2.0 is the dominant version used in enterprise SSO deployments.
Why SAML Matters for Your Cybersecurity Career
SAML misconfigurations like signature-wrapping attacks and assertion replay are common penetration test findings. Security engineers configure SAML integrations for enterprise apps. Knowing how SAML assertions flow between IdP and SP is critical for troubleshooting SSO failures and detecting authentication anomalies.
