Which identity management system method is primarily focused on web applications rather than traditional networks?

The focus of OAuth is on enabling secure authorization for web applications rather than the traditional network protocols used for authentication and access control. OAuth provides a way for applications to access user data without requiring users to disclose their login credentials. This is particularly significant in scenarios where web applications need to access resources on behalf of a user, such as allowing a third-party app to access a user’s data from another service like a social media platform.

OAuth operates under a principle of delegating access, enabling users to give limited access rights to applications, thereby enhancing security while simplifying the user experience by eliminating the need to share passwords with third-party applications. This method is especially beneficial for APIs and microservices within web environments, making it the go-to solution for securing modern web applications.

In contrast, methods such as TACACS+, RADIUS, and Kerberos are more traditionally associated with local network access control and authentication. These protocols are used primarily for network-level security and don’t typically focus on the specific requirements and nuances of web-based applications, making them less suitable for web-based identity management scenarios.
