Which of the following should be configured to protect workstations from unauthorized access when users step away?

Configuring a screen saver to activate after a certain period of inactivity is an effective way to protect workstations from unauthorized access when users step away. When engaged, the screen saver obscures the desktop and other visible information on the screen, thereby providing a visual barrier against prying eyes. Moreover, many operating systems allow the screen saver to be password-protected, requiring the user to re-enter their credentials (such as a password) in order to regain access. This adds an additional layer of security by ensuring that only authorized individuals can unlock the workstation after it has been inactive for a set duration.

In contrast, while a lock icon may indicate a secure state or be present in a system interface, it does not actively prevent access unless the workstation is locked feature is used. Taskbar auto-hide functionality merely minimizes the taskbar to maximize screen space and does not contribute to security measures against unauthorized access. Desktop wallpaper only serves as a visual preference and does not prevent access to the system when the user is away. Thus, implementing a screen saver, especially with password protection, is a proactive step in safeguarding sensitive information during periods of inactivity.
