In today's world we have many issues in internet security and privacy. We use internet in travelling, E-Commerce site, social media, banking, study etc. But we often face the problems with the privacy of the network system and private data. To accommodate this increase in application and data complexity, web services have moved to a multi-tiered design wherein the web server runs the application front-end logic and data is outsourced to a database or file server. IDS play a key role in computer security technique. But it also has drawbacks of its own. To overcome those drawbacks Duel Security technique is introduced based on ecommerce application. We are implementing duel security using MD5 algorithm and hashing function, an in built web server of windows 7 ultimate, with My SQL Server. This System presents those models the network behaviour of user sessions across both the front-end web server and the back-end database. Implementing system monitoring both web and subsequent database requests. Most of the people do their transaction through web use. So there are chances of personal figures gets hacked then need to be provide more refuge for both web server and database server. For that purpose duel security system is used. The duel security system is used to identify & prevent attacks using Intrusion detection system. Duel security prevents attacks and prevents user account data from unauthorized updating from his/her account.
