...Internet Security. Abstract Online users today are faced with multitude of problems and issues. A typical online user is vulnerable to virus, worms, bugs, Trojan horses etc.; he/she is also exposed to sniffers, spoofing their private sessions; and they are also vulnerable to phishing of financial information. Not only this but users are also constantly subjected to invasion of privacy with the multitude of spy ware available for monitoring their surfing behaviours.
