Now today’s entire world have we many issues in internet security and privacy. Research survey discusses regarding privacy and security is based on the use of internet in travelling, E-Commerce site, social media, banking, study etc. Existing system also often faces the problems with the privacy of the entire network system and stored private data. To overcome these issues, increase widely used application and data complexity, so web services have design to a multi-tiered system wherein the web server runs the application front-end logic and data is retrieve to a database or file server. Intrusion detection system plays a key role in computer security technique to analysis the data on the server. This problem overcome in proposed Duel Security technique is introduced based on ecommerce application. For data security we use the message digest algorithm, an in built web server of windows platform, with database My SQL Server. In this paper proposed system monitoring both web request and database requests. Most of the people do their transaction through web based server use. 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.

Keywords; Duel security, MD algorithm, Intrusion detection, multi-tier web application, data leakage detection.
