P.Rajapandian, Dr.K.Alagarsamy . Intrusion Detection in Dos Attacks. International Journal of Computer Applications. 15, 8 ( February 2011), 33-37. DOI=10.5120/1967-2634
Different signature or misuse based intrusion detection techniques; anomaly detection is accomplished of detecting novel attacks. However, the use of anomaly detection in practice is vulnerable by a high rate of false alarms. Pattern based techniques have been shown to make a low rate of false alarms, but are not as efficient as anomaly detection in detecting novel attacks, particularly when it comes to network probing and Denial-Of-Service (DOS) attacks. In this paper we find a new approach that merge pattern-based and anomaly-based intrusion detection, mitigating the weak point of the two approaches while increasing their strengths. Our approach begins with network protocols, and expands these state machines with information about statistics that need to be maintained to detect anomalies.
