Need for Suggestions for Security Design for a Web Application

advertisements

i'm designing a security module for a web application using spring security . There are 3 separate wars(3 Apps)using separate login, deployed in a JBOSS Server. The requirement is , If the user is authenticated in one app then he should be able to access other applications without login . Is it possible to share the security context between the web application( different wars not in a single EAR ). We discussed about the SSO , but we are trying to achieve this with spring security and with support of the App server . Is there any way ? Please provide your valuable suggestions and inputs. If you need more information, please let me know.


The easiest way is to employ usual Spring Security authentication (e.g. form-based with username/password) and enable the remember-me feature.

As long as all three applications are deployed on the same domain (and can therefore share their cookies), the remember-me feature will work seamlessly for all of them, i.e. once user authenticates at any of the applications she will be able to access the others without need for re-authentication.

This of course doesn't address issues like single logout, but that doesn't seem to be your aim anyway.

You can set this up in a short time and don't need and third party SSO components. Although relaying on standard SSO protocols and dedicated technologies tends to be a more secure option.
