What does SSO stand for in the context of network authentication?

Single Sign-On (SSO) is a user authentication process that allows a user to access multiple applications with one set of login credentials. This method enhances security and improves user experience by reducing the number of times a user needs to log in throughout their session across various systems or applications.

With SSO, once a user has authenticated their identity with one application, they gain access to other applications without needing to re-enter their credentials. This is particularly beneficial in enterprise environments, where users interact with numerous services throughout the day. Additionally, SSO can simplify password management for IT departments, reduce the risk of password fatigue, and streamline access controls.

Given the context of network authentication, the concept of Single Sign-On plays a vital role in promoting efficiency and security within IT systems, establishing it as the correct answer in this scenario.
