To prevent DNS hijacking attacks, start by using a reputable DNS provider with strong security features like DNSSEC to validate responses. Enable two-factor authentication (2FA) on your DNS management accounts to block unauthorized access. Regularly update router firmware and use a secure password to avoid local hijacking. Configure your network to use encrypted DNS protocols, such as DNS over HTTPS (DoH) or DNS over TLS (DoT), to protect against interception. Avoid public Wi-Fi for sensitive tasks, or use a VPN to encrypt traffic. Monitor DNS traffic for unusual patterns and set up alerts for suspicious activity. Finally, educate yourself and your team about phishing attempts that could trick users into visiting fake sites, leading to DNS manipulation. Stay proactive and keep security tools updated to minimize risks.
