What is the purpose of a session lock?

A session lock serves the critical function of temporarily restricting access to a user’s session when they step away from their device. This is particularly important in environments that prioritize security, as it prevents unauthorized users from easily accessing sensitive information that may be visible on the screen or retrievable from the session.

By locking the session, the system ensures that the user’s ongoing work and data remain secure while allowing the legitimate user to quickly resume their session upon return. Security protocols often recommend session locks as a best practice to protect data integrity and confidentiality in both personal and professional settings.

In contrast, other options do not accurately represent the purpose of a session lock. Continuous user authentication is not intended to permanently log users out or to establish a new session. While enhancing bandwidth for remote access addresses a different aspect of network performance, it is not related to session security and control. Therefore, the primary function of a session lock is to safeguard ongoing sessions from unauthorized access when users are momentarily unavailable, making it clear why this answer is the most appropriate.
