IP SPOOFING

Abstract

In this age of universal electronic connectivity , of viruses and hackers , of electronic eaves-dropping and electronic fraud , there is indeed no time at which security does not matter .

Security is the Science and study of protecting software (by means of n/w security mechanisms: Firewalls , Intrusion Detection Systems , System providing access control to devices and mechanisms to ameliorate denial of service and distributed denial of service attacks) against spoofing (unauthorized access) , modification , analysis or exploitation. Security remains a major hurdle to the universal acceptance of the web for many kinds of transactions .

The explosive growth in computer systems and their inter connections via networks has increased the dependence of both organizations and individuals on the information stored and communicated on these systems. This , in , turn has led to a heightened awareness of the need to protect data and resources from disclosure , to guarantee the authenticity of data and messages , and to protect systems from network based attacks.

As the disciplines of cryptography and network security have matured , there is a need to the development of practical and readily available applications to enforce network security. Every one has a different view about security and hence different security procedures have come up. But before adopting any of these it is essential to understand what actually network security is , the type of attack ,and the security procedures .

Criminals have long employed the tactic of masking their true identity, from disguises to aliases to caller-id blocking. It is not a surprise then, that criminals who conduct their nefarious activities on networks and computers employ such techniques. IP spoofing is one of the most common forms of on-line camouflage.
In this paper , we present IP – Spoofing : the attack in brief and the possible ways of securing the network against spoofing .
