Omar Siliceo, a professional Systems Engineer with a Master of Science degree in Electrical Engineering, started his IT career in the year 1991 as a Research Specialist, performing the roles of systems specialist, Internet and Unix systems administrator, and Internet systems consultant, when he was invited to join the Computer Center group at Vanderbilt University. In 1994, he joined the information technology team as a consultant, performing systems integration at the King Faisal Specialist Hospital and Research Centre in Saudi Arabia. After returning to the United States of America in 1997, he launched his IT consulting practice, creating partnerships with companies such as CTG and Ajilon. During the period from 1997-2004 he spent most of it (1997-2002) working with IBM in finding e-commerce solutions for customers such as Macy's, the NBA Store and Blair, and event Cybercast Infrastructure Administration for customers such as The Wimbledon Championships and The Masters Golf Tournament. It was during this period that he became exposed to early WebSphere technologies, including but not limited to WebSphere Application Server, WebSphere Commerce Suite, WebSphere Portal, and WebSphere Everyplace Suite.

In his last year with IBM, he focused on providing design, programming consultation, and problem solving to Fortune 500 software vendors and software integrators who were IBM's business partners. Between 2002 and 2004, he served as a consultant to The World Bank Group and Blue Cross Blue Shield of Florida. His role was the administration of WebSphere environments including some special projects such as the rollout of the latest version of their WebSphere environments. In 2004, he interrupted his consulting practice when he was invited to join the IT engineering team at Cummins, Inc. He served as Senior Web Technologies Engineer and later on as the Web Deployment team manager. As Senior Engineer, he architected the infrastructure environment for WebSphere 5.1, defining standards for platform creation, WAS deployment, and integration with existing enterprise technologies and services. In 2008, he resumed his consulting practice, supporting WebSphere Application Server, WebSphere Portal, and WebSphere Edge Components efforts and initiatives with Bank of America (2008), Blue Cross Blue Shield of Florida (2008 2009), and The World Bank Group, where he is currently Senior WebSphere Suite consultant.

IBM WebSphere Application Server Network Deployment is IBM's flagship J2EE application server platform. It implements the J2EE technology stack. This stack enables the WebSphere Application Server platform to execute the user's Java enterprise applications that perform business functions. There are several roles who use this platform such as architects, developers, and administrators, to mention a few. Within the administrator role, in turn, there are several functions such as installation, performance, security, and so on.

This book starts with an in-depth analysis of the global and administrative security features of WebSphere Application Server v7.0, followed by comprehensive coverage of user registries for user authentication and authorization information. Moving on you will build on the concepts introduced and get hands-on with a mini project. In the next chapter, you work with the different front-end architectures of WAS along with the Secure Socket Layer protocol, which offer transport layer security through data encryption.

You can learn user authentication and data encryption, which demonstrate how a clear text channel can be made safer, by using SSL transport to encrypt its data. This book will show you how to enable an enterprise application hosted in a WebSphere Application Server environment to interact with other applications, resources, and services available in a corporate infrastructure. Platform hardening, tuning parameters for tightening security, and troubleshooting are some of the aspects of WebSphere Application Server v7.0 security that are explored in the book. Every chapter builds strong security foundations, by demonstrating concepts and practicing them through the use of dynamic, web-based mini projects.
