The primary function of Security Assertion Markup Language (SAML) is to provide an open standard for authentication and authorization. SAML is an XML-based framework that enables single sign-on (SSO) for users across different domains without requiring them to log in multiple times. It allows the transfer of authentication and authorization data between an identity provider (IDP) and a service provider (SP), enabling secure sharing of user identities and attributes.

By leveraging this standard, organizations can streamline access to various services and applications, allowing users to access resources seamlessly without repeated credential submissions. This not only enhances user experience but also strengthens security by centralizing authentication processes and implementing consistent access controls.

In contrast, the other choices focus on different aspects of IT and cybersecurity. Creating a secure network for internal communications primarily pertains to network security measures, while managing directory services relates to resource management and access control within an organization. Overseeing data encryption in web browsers deals with protecting data in transit rather than the authentication and authorization process that SAML addresses.
