To meet application security requirements, which two authentication methods must applications support?

In the context of meeting application security requirements, supporting Security Assertion Markup Language (SAML) and OAuth 2.0 is integral to ensuring a robust authentication framework.

SAML is a widely adopted standard for federated authentication, which allows users to authenticate once and gain access to multiple applications without needing to log in separately to each one. It primarily operates in a Single Sign-On (SSO) environment, facilitating secure exchanges of authentication and authorization data between an identity provider and a service provider. This is crucial in enterprise settings where user experience and security are paramount.

OAuth 2.0, on the other hand, is an authorization framework that enables third-party applications to obtain limited access to user accounts on HTTP services, without sharing passwords. It supports various types of application architectures, including web applications, native applications, and service-to-service interactions, making it versatile in modern application development. Its support for delegated access is particularly relevant in cloud environments and scenarios where applications interact with APIs securely.

Both SAML and OAuth 2.0 address the need for modern applications to securely manage identities and permissions, aligning well with the requirements imposed by current cybersecurity practices. The other methods, while potentially useful in certain contexts, either do not focus on the broader application
