CompTIA Network+ Practice Test

How can users protect themselves from evil twin attacks?

1. By using strong passwords for all accounts

2. By using HTTPS and a VPN

3. By ensuring their devices have antivirus software

4. By regularly updating device firmware

The correct answer is: By using HTTPS and a VPN

To safeguard against evil twin attacks, it is crucial to help ensure secure communications over potentially compromised networks. This is effectively achieved by using HTTPS and a VPN. HTTPS encrypts the data transmitted between a user's browser and the web server, which prevents attackers from intercepting or tampering with the information being exchanged. When users connect to a malicious access point—an evil twin—this encryption minimizes the risk of sensitive data being captured. In addition, a Virtual Private Network (VPN) provides an additional layer of security by encrypting all internet traffic from the user's device before it reaches the internet. This means that even if a user connects to an unsuspecting network controlled by an attacker, the data remains encrypted, thus protecting it from interception. While using strong passwords, having antivirus software, and regularly updating device firmware contribute to a general security posture for devices and accounts, they do not specifically address the threats posed by an evil twin attack during network sessions.
