First, they can use Domain Name System Security Extensions (DNSSEC) to digitally sign DNS data to ensure its authenticity. Additionally, they can regularly monitor their DNS records for any unauthorized changes and implement strong authentication measures to prevent unauthorized access to DNS settings. It is also important to keep software and systems up to date with the latest security patches to prevent vulnerabilities that could be exploited for DNS hijacking. Finally, organizations can consider using a reputable and secure DNS service provider to help mitigate the risk of DNS hijacking. **
