Security for mailing Applications

Security plays a major role in the software world. All our confidential and important documents need to be secure. The primary object of our project is to develop a security provider for the mailing applications.

CRYTOGRAPHY is the tool which is used in our project. We are using Java platform for it’s in built security feature and usages in the network communications.

Nowadays Internet has become unsecured as there are lots of malicious programs written by some twisty people which may contain Trojan horse, virus/worms and not fully secured. Java consists of sand box security which ensures that entrusted entries are not allowed with limited access and capabilities at end users machines. The sandbox is responsible for protecting a number of resources, and it does so at a number of levels. The user’s machine has access to many things:
§ Internally, it has access to its local memory.
§ Externally, it has access to its file system and to other machines on LAN.
§ For running applets, it has access to a web server, which may be on its local net or may be on the Internet
§ Data flows through this entire model, from the user’s machines through the network and to disk.

Each of these resources need to be protected and those protection from the basis of Java’s security model. Our security provider has features which will make us to download or use only trusted and reliable applications and in this way it safeguards the system.
