Intrusion Detection Using Double Guard System

Abstract

In today's world we have many issues in internet security and privacy. We use internet in travelling, social media, banking, study etc. But we often face the problems with the privacy of the network system. To accommodate this increase in applications and data complexity, web services have introduced the multi-tiered design in which the web server runs the application front-end logic and as well as data is updated to database or file server. IDS plays a vital role in computer security technique. But it also has its own limitations. To overcome those limitations Double guard technique is introduced. We implemented double guard using IIS (internet information and service manager), with the software’s such as SQL Server, Visual Studio, .NET and programming language Java Script. This project presents Double Guard, an IDS system that describes the network behavior of user sessions across both the front-end web server and the back-end database. By handling both web and subsequent database requests, it is possible to prevent the attacks that an independent IDS couldn’t. Along with this we use Virtual Split Memory that separates code and data into different memory spaces. Finally, this system will detect intrusions in multi -tier applications and prevent it, enhancing the internet security and privacy.
