To minimize the impact of malicious redirection of web traffic within a network, which of the following measures would MOST effectively authenticate legitimate responses?
Deploy network firewalls at key perimeter points
Implement and configure DNSSEC for servers
Increase the complexity of network passwords
Regularly update antivirus software on client machines
Implementing and configuring DNSSEC on servers targets the root cause of malicious traffic redirection by authenticating the origins of the data, ensuring that the data integrity is maintained. This specific alignment with protecting against unauthorized changes and redirection aids in counteracting the effects of malicious web traffic redirection techniques. Other options, while beneficial for overall security, do not specifically authenticate the source of web traffic data, which is crucial in mitigating this type of attack.
