Chapter 10. Malicious Java Applets
Browse a web page containing a Java applet, and by default, it executes. Often, you don’t even know it’s happening. The creators of Java understood how powerful self-executing code is and included built-in security features. In the Java world, untrusted code is forced to run in a secured environment. If you trust an applet, what it can do depends on what browser you are using and what permissions you’re allowed. Chapter 10 will cover hostile Java code and browser Plug-ins.

Java , developed by Sun Microsystems (http://www.sun.com), is a programming language just like any other you might be familiar with. Although it is not C++, it was intentionally written with a similar syntax to decrease the learning curves of the many C++ programmers today. It is easier to learn than C++, has better memory management, and has been optimized for network distribution. Today, when you hear Java, it can mean the Java programming language or the whole platform of programming tools designed to support the core language.
