definition of terms

SAML (Security Assertion Markup Language) is an open standard for the secure transfer of authentication and authorization data between an identity provider (IdP) and a service provider (SP). The protocol is based on XML and is primarily used in corporate and government environments for single sign-on (SSO).

What is SAML?

SAML (Security Assertion Markup Language) enables users to log in once centrally and then access various services without having to authenticate themselves again. Centralized login takes place at the identity provider, which issues a digital identity confirmation—the SAML assertion. This is accepted by the service provider to grant access.

How does SAML work?

SAML (Security Assertion Markup Language) enables secure login across different applications—typically as part of single sign-on (SSO). Two central systems communicate with each other:

• Identity provider (IdP): verifies the user's identity, e.g., through a username, password, or multi-factor authentication.
• Service provider (SP): provides the requested application or website and relies on the IdP for authentication.

Advantages:

• Single sign-on (SSO): Single login for multiple applications.
• Secure data exchange: Digital signatures prevent manipulation.
• Centralized authentication: Reduces user administration and password management.
• Compatibility: Standardized and widely used in corporate and government environments.

Conclusion

SAML is a central component of modern identity and access management (IAM) systems. The protocol enables secure, standardized authentication across different applications and reduces the effort required by both users and IT.

Companies benefit from uniform single sign-on, reduced password usage, and increased security through centralized authentication policies such as multi-factor authentication and zero trust.

SAML ensures seamless access, consistent security, and a better user experience, especially in complex, hybrid IT environments.
