The end users of a SaaS application use multiple services from the same application. A unique login ID and password are required for each user to access each service. Which of the following access…

RBAC (Role-Based Access Control) is an authorization method that assigns permissions based on user roles, not a method to simplify the initial authentication process across multiple services.

SAML (Security Assertion Markup Language) is an XML-based standard for exchanging authentication and authorization data between an identity provider and a service provider. Implementing SAML allows users to authenticate once with an identity provider and then gain access to multiple services (service providers) without re-entering credentials, which is the core principle of Single Sign-On (SSO). SAML facilitates the federation of identity, simplifying access across multiple services.

SSO (Single Sign-On) is the desired outcome of simplifying access, but SAML is a specific protocol or method used to achieve that outcome.

MFA (Multi-Factor Authentication) enhances security by requiring multiple verification factors but does not simplify the process of accessing multiple services with different credentials.
