Which method can be used to counteract phishing attacks?

Implementing strong multi-factor authentication (MFA) protocols is an effective method to counteract phishing attacks because it adds an additional layer of security beyond just a username and password. Even if a user's credentials are compromised through a phishing attack, the attacker would still need to provide a second factor of authentication, such as a code sent to the user's mobile device or a biometric verification. This greatly reduces the chances of unauthorized access, as the attacker is unlikely to possess both pieces of information required to gain entry.

In contrast, while regular software updates can enhance security by fixing vulnerabilities, they do not specifically target the issue of credential theft that occurs with phishing. Limiting internet usage during work hours may help reduce exposure to phishing attempts, but it is not a comprehensive solution. Conducting performance reviews, while important for employee assessment and motivation, does not address the direct threat posed by phishing attacks and does not enhance cybersecurity measures. Thus, MFA stands out as a robust defense mechanism specifically designed to mitigate the risks associated with phishing.
