TAILIEUCHUNG - Simplified tcp based communication approach towards domain name system for improving security
By exploiting this vulnerability the attacker can launch different types of attacks like Cache Poisoning, DNS Spoofing, Protocol corruption, Zone corruptions, Session Hijacking, etc. Although the use of UDP makes the system faster, ye, it is suggested that all DNS based communications should be TCP based rather than UDP. | ISSN:2249-5789 Alok Pandey et al , International Journal of Computer Science & Communication Networks,Vol 3(6),347-357 Simplified TCP Based Communication Approach towards Domain Name System for Improving Security Alok Pandey1 , Dr. Jatinderkumar R.

Without DNS, the only way to reach other computers on the Internet is to use the numerical network address. The use of IP address for locating and connecting to remote systems is tedious and is not very user friendly. A preferable and much relied upon service for retrieving an IP address just by referencing a FQDN is DNS. Several types of DNS based communications take place on the internet which are exploited by the cyber criminals for attacking systems. Although different mechanisms have been suggested by the research community to secure the DNS based communications yet it is still not fully secure. Since DNS does not necessarily require the establishment of a TCP connection it allows the attackers to redirect the response to the victims host by spoofing the source IP address as the victims IP address. By exploiting this vulnerability the attacker can launch different types of attacks like Cache Poisoning, DNS Spoofing, Protocol corruption, Zone corruptions, Session Hijacking, etc. Although the use of UDP makes the system faster, ye, it is suggested that all DNS based communications should be TCP based rather than UDP.
