What is the full form of SAML?
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 is Security 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.'
