A Secure-DNS Scheme Against Spoofing Attacks

Domain Name System spoofing is a cyber-attack in which information is passed into Domain Name System server which results in wrong Internet Protocol address, in turn causes communication to wrong computer system. Checking users’ actions, allocating malwares and spam, and threatening rightness and ease of use of networks, is also caused by this. The Domain Name System spoofing is a Man-in-the-middle attack which transfers incorrect information to a host. Securing data through encryption and decryption is not likely used to avoid this attack. In this paper we assume that hackers are able to get man- in-the-middle abilities and weedy hackers are able to challenge Domain Name System defense. Vulnerabilities which because spoofing is also discussed here. Domain Name System Security is designed to prevent spoofing by authenticating the users thereby providing security of the information. This method stands as a strong defense against Domain Name System Spoofing by integrating the concept of digital signature along with cryptographic techniques.
