The Domain Name System (DNS), a universal system that converts domain names into IP addresses, has a set of security extensions called DNSSEC (Domain Name System Security Extensions). A method called DNSSEC gives the DNS security and forgery protection.
In order to confirm the legitimacy and integrity of DNS data, DNSSEC makes use of public-key cryptography and digital signatures. With DNSSEC, a DNS resolver can check the authenticity and integrity of the information received from a DNS server and reject any replies that don’t adhere to the security requirements.
DNSSEC aids in defending against several security risks to the DNS, such as cache poisoning, which allows an attacker to divert DNS traffic to a false IP address, and domain hijacking, in which an attacker seizes control of a domain name by altering the DNS records related to the domain name.
For domain owners and DNS providers, DNSSEC adoption is an optional but recommended security solution. By putting DNSSEC into practice, domain owners can improve the security and dependability of their domain name system and shield their users’ data from hackers and other security risks.
