3.  Internet services and applications have becomean inextricable part of daily life, enabling communication and the management of personal information from anywhere.  In this paper, we present Double Guard, an IDS system that models the network behavior of user sessions across both the front-end webserver and back-end database.

4.  Double Guard: Detecting intrusions in multitier web applications

5.  DoubleGuard :Detecting Intrusions in Multitier Web Appliction.  Authors-: Meixing Le,Angelos Stavrou Brent ByungHoon Kang The paper suggests the model for the use of Double Guard Detecting intrusion in Multitier web Application is very more security.

6. Limitation of Security -: Low Secure Authentication Low User Identification mechanism Low computational power Low Content Security

7.  Threat model to include our assumption & type of attacks we are aiming to protect against.  The attack are network borne & come from the web client, they can launch application layer attack to compromise the webserver they are connecting to.

11.  Privilege Escalation attack  Hijack Future session Attack  Injection Attack  Direct DB Attack

13.  More Secure Authentication  For Organization Security

14.  Hardware Required: o System : Pentium IV 2.4 GHz o Hard Disk : 40 GB o RAM : 256 MB

15.  Software Required:  O/S : Windows XP. Win 07.  Language : Asp.Net with c#,java,  Data Base : Sql Server 2005

16.  We presented an intrusion detection system that builds models of normal behavior web appliction from both front end web request and back end database queries.  DoubleGurad forms a container based IDS with multiple input stream to produce alerts.
