Security第 44 / 100 题
A user wants to prevent unauthorized people from reading over their shoulder as they type a password in a public place. Which countermeasure is most directly relevant?
a.Enabling a firewall
b.Updating antivirus
c.Using a longer Wi-Fi key
d.Using a privacy screen filter and shielding the keyboard
解析
A privacy screen filter narrows viewing angles and shielding the keyboard defeats shoulder surfing in public. Firewalls, antivirus, and Wi-Fi keys do not stop someone physically observing the screen or keystrokes.
