DNS Security

DNS security, also known as Domain Name System security, is a set of measures that are taken to protect the Domain Name System (DNS) from cyber threats and to ensure the integrity and availability of DNS services.

The DNS is a critical infrastructure component that is used to translate domain names (such as www.bigfishtec.com) into IP addresses, which are used to route traffic on the Internet. As such, it is an attractive target for cyber-attackers, who may seek to exploit vulnerabilities in the DNS to gain access to sensitive information or to disrupt Internet services.

DNS security involves a variety of measures, including the use of encryption and secure protocols, such as DNS over HTTPS (DoH) and DNS over TLS (DoT), to protect DNS traffic from interception and tampering. It may also involve the use of security controls, such as firewalls, intrusion prevention systems, and access controls, to protect DNS servers and networks from attack.

DNS security is important for protecting the integrity and availability of DNS services and is an essential part of a comprehensive security strategy.
