Which of the following is NOT a method to prevent Man in The Middle attacks?

The method of using unfamiliar public WIFI is indeed not a valid approach to prevent Man in The Middle attacks. Public WIFI networks are often unsecured and can be easily exploited by attackers to intercept data. When a user connects to an unfamiliar public WIFI, they may unknowingly allow an attacker access to their sensitive information, making them more vulnerable to such attacks.

In contrast, methods like installing anti-virus software, ensuring strong usernames and passwords, and being cautious of phishing emails all contribute significantly to security. Anti-virus software can help detect and block malicious activity that might be used in Man in The Middle attacks. Strong usernames and passwords create a barrier that makes it harder for attackers to gain unauthorized access to accounts. Furthermore, being cautious of phishing emails prevents users from unintentionally providing sensitive information that might be intercepted during a Man in The Middle attack.

Together, these methods build a robust defense against various cyber threats, while connecting to unfamiliar public WIFI typically undermines security measures.
