Senior Java Developer/Security Architect

Responsibilities/Description: Integrate a custom authentication and

federation solution, Understand/ customize the Struts based Tricipher

Authentication Gateway (TAG) and Develop a SAML Consumer using openSAML.

This project was about customizing the TAG which included java/j2ee based

development. The TAG provides multi factor authentication including browser

2-factor cookie, client certificate, challenge questions etc. The TAG was

customized to authenticate users against the ADAM directory instance and

send a SAML assertion to the Juniper SSL VPN for authorization. After the

Juniper authorizes the user, it sends another SAML Assertion to the SAML

consumer module of the access gate developed using Oracle Access Manager

SDK API. The access gate then creates the Single-sign on (SSO) cookie and

sends it back to the user. From then on the user can easily access multiple

applications due to the SSO cookie.
