A PROACTIVE NETWORK SURVEILLANCE FRAMEWORK

Network security paradigm should be the one that permeates the enterprise, including people, processes and technology. Security failures occur when there is presence of weak spots among any of these. An organization which can not detect and remove such weak spots is going to perish. As can be seen around, most of the organizations today apply a few or many of the existing tools and techniques like ¿rewalls, intrusion detection systems, anti-viruses, anti-spywares etc., to safe-guard the systems against hacking community. But as the number of network breaches, from outside as well from inside, are still on rise, much works needs to be done.This work analyzes trends in network security through an investigation of reactive and proactive network security strategies. Many of common practices have been studied, analyzed, compared and reported in this work. Prior to proactive security research, there existed a meager know how about the "who is our enemy?", "what tools and techniques they use to attack networks?", "what are their motives to do so?"etc. This knowledge was quite limited and primarily anecdotal. This made it di¿cult to create, test and deploy integrated security solutions, for better and e¿cient Network Security.
