Internet) technologies evolve, security attacks are becoming more sophisticated and
frequent. Staying on top of the most up-to-date techniques and tools is one key to application
security; the other is a solid foundation in proven technologies such as data encryption,
authentication, and authorization.
The Java platform, both the basic language and library extensions, provides an excellent
foundation for writing secure applications. This tutorial
