IJIRCSTJournal International Journal of Innovative Research in Computer Science and Technology I S Volume 2 Issue 2 Computer Science & Engineering English March - April 2014 N N Y 2019 11 12 Computer Sciences Secure Network Communication Using Vulnerability Assessment Technique English Y 14 18 Preethi.S English Y Vinodhini.T English N Vulnerability assessment has become an area of interest in distributed network communication which is capable of detecting the penetrations, break-ins and other form of computer abuse. The communication between a team and Management Information Base (MIB) within an organization which is out of the scope of firewall authentication can be made possible with the help of this system. In this paper, we propose an intrusion detection mechanism which is capable of detecting heterogeneous wireless sensor network (WSN) by characterizing intrusion detection with respect to the network parameters (Destination IP). The intention of this system is to reduce susceptibility using vulnerability assessment algorithm which covers the process of identifying and ranking the vulnerabilities in a system while ensuring required information is transferred securely without any failure in the middle of transaction. The three basic ideas involved are Furtive enigma, Destination IP address and Unlock key. It mainly focuses on system security by detecting the intruders and their system can be crashed by displaying a gray screen on it by comparing the IP address with the available IP address list.
