What password practice should a technician implement to secure a private PC in a public workspace?

Requiring authentication on wake-up is a crucial practice for securing a private PC in a public workspace. This means that when the computer goes into sleep or hibernation mode, it will need a password or some form of authentication to be re-accessed. This effectively prevents unauthorized access to the system when the owner is away from their desk, which is particularly important in a public environment where others can easily approach the unattended device.

Implementing this measure significantly enhances security by ensuring that sensitive data remains protected, even in situations where the device is temporarily left unattended. Without this requirement, anyone could simply wake the computer and access potentially sensitive information. This practice is a standard recommendation for security in both personal and professional environments.

While the other options might improve security in different contexts, they do not specifically address the immediate risk of unauthorized access when a computer is left unattended in a public area.
