SECURITY OPTIMIZATION OF DYNAMIC NETWORK WITH OPTIMAL DEFENSE STRATEGY AND INTRUSION DETECTION

Abstract

– Network security has become more important to personal computer users, organizations and the armed
forces. With the beginning of the internet security became a major concern and the history of security permits a better
understanding of the emergence of security technology. Acquiring the networks of large organizations is technically
challenging due to the multipart configurations and constraints. A network administrator needs to identify vulnerable
configurations, as well as tools for hardening the networks. Unauthorized intruder or attacker into a computer system or
network is one of the most serious threats to computer security. Many of them try to access the resources of an unauthorized
person to win their business. The proposed methods identifies the attack hosts with the help of two models (i) success
predictable model attain the expected chance vulnerability attacks in a network, and block the repeated IP address with the
help of intrusion detection (ii) security enhancement model implement the optimal defense strategies with a method of
secured login system by three matching pattern is used identify the intruder and hackers for wired devices and wireless
connections. This will help to secure data in large organizations
