Description: SAML (Security Assertion Markup Language) is an open standard designed to facilitate the exchange of authentication and authorization data between different parties, especially in multi-domain environments. This language allows users to access multiple online applications and services using a single identity, simplifying credential management and enhancing user experience. SAML uses assertions, which are statements about the user’s identity and attributes, to transmit security information between an identity provider (IdP) and a service provider (SP). This approach not only enhances security by reducing the need for multiple passwords but also enables organizations to implement single sign-on (SSO) solutions, resulting in greater operational efficiency. SAML is widely used in enterprise and educational environments, where the integration of multiple applications and services is common. Its ability to interoperate across different platforms and technologies makes it an essential tool in modern security architecture.
History: SAML was developed by OASIS (Organization for the Advancement of Structured Information Standards), with its first version, SAML 1.0, published in November 2002. Since then, it has evolved through several versions, with SAML 2.0 being the most widely used, released in March 2005. This evolution has enhanced interoperability and security in the exchange of authentication and authorization data between different systems.
Uses: SAML is primarily used in enterprise and educational environments to implement single sign-on (SSO) solutions, allowing users to access multiple applications with a single authentication. It is also applied in identity federation, where different organizations can securely share identity information.
Examples: A practical example of SAML is its use in various platforms, where users can log into multiple applications using their credentials just once. Another example is the use of SAML in systems that allow users to access services through a single authentication.
