Abstract
The Domain Name System (DNS) is a distributed approach of mapping the domain name attributes with their respective IP addresses. The DNS has inadvertently been an attack target since its inception. The attack vectors have subsequently given rise to the amendments in protocols and various other techniques that defer or mitigate the risk factors of the same. In this paper, an analytical review of the vulnerabilities and threats of the DNS and its various security implications has been discussed. DNS Security Extension (DNSSEC), a public key cryptographic approach proposed by the Internet Engineering Task Force (IETF) to protect the integrity of the DNS records, has further been presented. Further, in this paper, the DNSSEC architecture, usage, and operational security flaws which subsequently might compromise the integrity of the DNS are also presented.
