Enhancing Cyber Defense: A Comprehensive Study of DNS Security

Abstract

As the internet continues to evolve, robust security measures are becoming increasingly vital at every stage. One crucial component, the Domain Name System (DNS), plays a pivotal role in helping users access websites. However, its lack of inherent security mechanisms makes it vulnerable to exploitation. Unsecured DNS can be manipulated, leading to threats like DNS tunneling, hijacking, and cache poisoning. To address these vulnerabilities, DNSSEC (Domain Name System Security Extension) offers a critical layer of security for a safer DNS system. Keywords: DNS, DNSSEC, Tunneling, Cache poisoning, Hijacking
