Security plays an important role in distributed systems. All parts of a Jini djinn, which consists of clients, services, and lookup services, can be subjected to attack by hostile agents. You could trust everyone, but the large number of attacks that are made on all sorts of systems by both skilled and unskilled people doesn’t make this a reasonable approach. The Jini security model is based on the JDK 1.2 security system, and all components of a Jini system use the JDK 1.2 security mechanisms. This can be tricky to set up, and it is looked at in detail in this chapter.
