Applied security techniques for J2EE programmers and developers, written by a security expert at Hewlett Packard. Explains security concepts in simple terms and relates these to standards, Java APIs, software products and day-to-day job activities of programmers. Written by a practitioner who participated in the development of a J2EE App Server and Web Services Platform at HP. Applied security measures demonstrated on Java APIs - a unique feature of the book. Dealing with security issues continues to be challenging for programmers and developers. In this book, expert practitioner Pankaj Kumar walks through both the descriptions and resolutions of those security issues that Java professionals will run into while designing, building, deploying and operating solutions that use J2EE technologies - such as Servlets, EJBs and Web Services. Unlike most books on security, Kumar covers security concepts such as authentication, authorization, confidentiality, integrity and non-repudiation in the context of security standards, Java APIs and software products implementing these technologies, while demonstrating how to use these in creating solutions. Pankaj Kumar is a software architect at the Middleware Division of Hewlett-Packard Co. He participated in the development of a J2EE App Server and Web Services Platform, and maintained the overall performance, security, standards compliance, consistency and usability of middleware products. He also represented HP in two important Java Community Process (JCP) Expert Groups developing Java Web Services standards- JAX-RPC and JSR109. He has more than 14 years of industry experience includes working as a programmer, development manager and architect in a wide variety of middleware technologies and enterprise solution projects in Java and C/C++.
