Chapter 9 ▪ Security

When Java technology first appeared on the scene, the excitement was not about a well-crafted programming language but about the possibility of safely executing applets delivered over the Internet. Obviously, serving executable applets is only practical when the recipients can be sure the code won’t wreak havoc on their machines. Security therefore was and is a major concern of both the designers and the users of Java technology. This means that unlike other languages and systems, where security was implemented as an afterthought or as a reaction to break-ins, security mechanisms are an integral part of Java technology.

The security architecture was composed of three parts:
