Abstract: A technique for informing an Internet site operator of potential pharming attacks includes generating pharming alerts based on mismatches between a set of expected IP addresses and IP addresses obtained from DNS servers on the Internet and filtering the generated alerts based on circumstances surrounding the generated pharming alerts. Filtering the alerts blocks less suspect pharming alerts while allowing more suspect ones to pass to the site operator, reducing the rate of false positives and better enabling the operator to focus on alerts that may present actual threats.

Abstract: An improved system and method of measuring and evaluating a distributed denial of services (DDOS) attack includes arranging for a DDoS attack by engaging a network provider offering malicious services to attack a honeypot computerized device. The honeypot includes a packet sniffer used to measure the values of parameters of the DDoS attack useful in determining the method of attack, the origin and extent of the attack, in calculating methods for early determination that a DDoS attack is occurring, and methods of countering this type of DDoS attack before it occurs.
