Which of the following threats will the use of a privacy screen on a computer help prevent?

Impersonation involves pretending to be someone else, which a privacy screen does not prevent.

Shoulder surfing is the act of observing someone over their shoulder to glean sensitive information like passwords or financial data, and a privacy screen physically restricts the viewing angle of the display, making it difficult for anyone not directly in front of the screen to see its contents.

Whaling is a type of spear-phishing attack specifically targeting high-profile individuals, which a privacy screen does not address.

Tailgating is gaining unauthorized entry into a restricted area by following closely behind an authorized person, which is a physical security issue unrelated to screen visibility.
