DNS Security refers to measures taken to protect the Domain Name System, which translates human-friendly domain names into IP addresses. This system is crucial for internet functionality, but it can be vulnerable to attacks, such as DNS spoofing or cache poisoning, where attackers redirect users to malicious sites. To enhance DNS Security, techniques like DNSSEC (Domain Name System Security Extensions) are implemented. DNSSEC adds digital signatures to DNS data, ensuring its authenticity and integrity. By verifying that the information received is legitimate, DNSSEC helps prevent users from being misled by fraudulent websites, thereby improving overall internet safety.
