DNS hijacking is a sort of cyberattack in which cyber thieves utilize weaknesses in the Domain Name System to redirect users to malicious websites and steal data from targeted machines. Because the DNS system is such an important part of the internet infrastructure, it poses a serious cybersecurity risk.
These can be avoided by the following precautions:-
- Examine the DNS zones in your system.
- Make sure your DNS servers are up to current.
- The BIND version is hidden.
- Transfers between zones should be limited.
- To avoid DNS poisoning attempts, disable DNS recursion.
- Use DNS servers that are separated.
- Make use of a DDOS mitigation service.
