A technician is setting up a new workstation for a receptionist. The desk is located in the main lobby, and the monitor will be visible to visitors. The receptionist will be handling sensitive customer data. Which of the following security controls should the technician implement to BEST mitigate the risk of shoulder surfing?
The correct answer is to apply a privacy screen filter. A privacy filter is a physical security control that narrows the viewing angle of a monitor, making it difficult for anyone not sitting directly in front of the screen to see its contents. This directly mitigates the risk of shoulder surfing in a public-facing environment. While a software firewall and complex passwords are good security practices, they do not prevent an onlooker from viewing the screen. A keylogger is a type of spyware used to capture keystrokes and is a threat, not a security control.
