Explanation of terms

SAML (Security Assertion Markup Language) is an open standard for the secure transmission 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 the corporate and government environment for single sign-on (SSO).

What is SAML?

SAML (Security Assertion Markup Language) makes it possible for users to log in once centrally and then access various services without having to authenticate themselves again. The central login takes place at the so-called identity provider, which issues a digital identity confirmation - the SAML assertion. This is accepted by the service provider in order 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). This involves two central systems communicating with each other:

  • Identity provider (IdP): verifies the identity of the user, e.g. by username, password or multi-factor authentication.
  • Service Provider (SP): provides the requested application or website and relies on the authentication of the IdP.

Advantages:

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

Conclusion

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

Companies benefit from uniform single sign-on, reduced password usage and higher security thanks to central authentication guidelines such as multi-factor authentication and zero trust.

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