To increase functionality or add design embellishments, web sites often rely on scripts that execute programs within the web browser. This active content can be used to create “splash pages” or options like drop-down menus. Unfortunately, these scripts are often a way for attackers to download or execute malicious code on a user’s computer....

Assessing the security of Java applications, and particularly client-server applications, can be a tedious process of modifying the code, compiling, deploying, testing and repeat. This becomes even more difficult when the source code to the application is not available. What we require is an easy means of interacting with the internals of a Java...

The Java runtime keeps track of the sequence of Java calls that are made as a program executes. When access to a protected resource is requested, the entire call stack, by default, is evaluated to determine whether the requested access is permitted. As mentioned earlier, resources are protected by the SecurityManager. Security-sensitive code in the...

The access control architecture in the Java platform protects access to sensitive resources (for example, local files) or sensitive application code (for example, methods in a class). All access control decisions are mediated by a security manager, represented by the java.lang.SecurityManager class. A SecurityManager must be installed into the Java runtime in order to...

The Java language is designed to be type-safe and easy to use. It provides automatic memory management, garbage collection, and range-checking on arrays. This reduces the overall programming burden placed on developers, leading to fewer subtle programming errors and to safer, more robust code. In addition, the Java language defines different access modifiers that can...
