SAML (Security Assertion Markup Language) is an open standard for exchanging authentication and authorization data between parties, particularly in the context of single sign-on (SSO). It is based on XML and is widely used to enable secure web-based authentication and authorization across different domains. The correct full form isSecurity Assertion Markup Language, where "Assertion" refers to statements about a subject (e.g., identity, attributes), "Markup" indicates the XML-based structure, and "Language" denotes the defined syntax.
Option A ("Security Assertion Markup Language"): This is the correct and official full form of SAML as defined by OASIS (Organization for the Advancement of Structured Information Standards).
Option B ("Security Authorization Markup Language"): Incorrect, as "Authorization" is not part of the acronym; SAML focuses on both authentication and authorization assertions.
Option C ("Security Assertion Management Language"): Incorrect, as "Management" is not part of the acronym; SAML is about markup, not management.
Option D ("Secure Authentication Markup Language"): Incorrect, as "Secure" is not part of the acronym, and SAML covers more than just authentication.
The correct answer is A, aligning with the CAP syllabus under "Authentication and Authorization" and "Single Sign-On (SSO) Standards."References: SecOps Group CAP Documents - "SAML Overview," "Authentication Protocols," and "OWASP Identity Management" sections.
