Abstract

In the past few years organization have widely adopted local area network (LAN), wide area network (WAN) and internet to take advantages of advancement in technology1, 2. As a result of connecting private and internal network to the outside network, exchange of information is greatly facilitated. Individuals and organization worldwide can reach any point on the network through internet without regard to geographic boundaries or time of day3. However, along with the convenience and easy access to information, connecting private and internal network to outside untrusted networks bring new risks. Among them are the risks that valuable information will be lost, stolen, corrupted or misused by malicious people trying to gain some benefit or harm someone. Such an attack to an information system may be a passive attack or it may be an active attack. In passive attack, the principal goal of the attacker is to obtain information that is being transmitted. So passive attacker are of the nature of eavesdropping or monitoring of transmissions. In active attack, the attacker may want to modify the information or can send a false data stream to misguide the recipient of the message. It may be in the form of masquerading, when one entity pretends to be a different entity, or it may be in the form of modification messages.
