Malik, an office manager at a local bank branch, aims to protect customer information from unauthorized access when the deskside employees are not present at their desks. Which security concept would Malik use to address this issue?

A clean desk policy is designed to prevent confidential information and documents from being left on desks after hours, and it mandates that employees store such files in a more secure or less exposed location. Conversely, background checks, continuing education, and job rotation do not protect confidential information that is left on desks from exposure.
