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.
