Network security using java

Network security using java

Abstract:

Java is a new programming language from Sun Microsystems. The Java language has a number of interesting properties. One property is that it is intended to be portable, even to the extent that programs can be dynamically loaded over the network and run locally. In particular, small programs called applets can be loaded and run by a user's WWW browser while the user is ``surfing'' the Web and HotJava is such a browser written in Java, and Netscape2.0 will support Java applets. While this idea is very powerful, it is also an invitation to security problems. The Java language and runtime system includes libraries, the compiler, and the bytecode interpreter attempt to address these security issues, with the result that Sun claims Java will be secure.

As computer networks and Internet grow rapidly today, understanding and analyzing the network behavior especially in local area network are becoming important tasks for many network researchers to improve the network performance and to develop a new protocol or algorithms to meet new requirements, such as Quality of Service, Network Security.
Active network technology supports the deployment and execution on the fly of new active services, without interrupting the network operation. Active networks are composed of special nodes that are able to execute active code to offer the active services. This technology introduces some security threats that must be solved using security architecture.

The Java platform was designed with a strong emphasis on security. At its core, the Java language itself is type-safe and provides automatic garbage collection, enhancing the robustness of application code. A secure class loading and verification mechanism ensures that only legitimate Java code is executed.

Java's main feature is its ability to move code over a network and run that code. Unlike other languages, Java has been designed to do this securely. Java security has evolved over time; recent releases provide fine-grained security features that enable implementation of a flexible policy decoupled from the implementation mechanism.
