INTERNET SECURITY

ABSTRACT

In this age of universal Internet world, of viruses and hackers, of electronic fraud network security has assumed increasing importance. Security is a broad topic and covers a multitude of sins. It is concerned with making sure that nosy people can’t read, or even worse secretly modify messages intended for other recipients.

The need of security arises when unscrupulous competitors, masqueraders, crackers & whackers break up into a system intentionally for their benefits or to harm someone.

In this paper, we concern with how trusted computers be connected safely to an untrustworthy network. Absolute protection of information from malicious abuse is not possible, however computer networks provide provisions such as Intrusion Detection Systems, Firewalls, Cryptography, Virtual Private Networks, Public and Private Key Algorithms, Bluetooth etc. 

So the network security is somewhat misleading, because virtually all businesses, Government and academic organizations interconnect their data processing equipment with a collection of interconnected networks.
