Abstract:
Recently cyber security has emerged as an
established discipline for computer systems and
infrastructures with a focus on protection of
valuable information stored on those systems from
adversaries who want to obtain, corrupt, damage,
destroy or prohibit access to it. One of the securitythreat
which is difficult to address using traditional
network security techniques is Denial of Service
(DoS) attacks. We have seen increasing numbers of
denial of service (DoS) attacks against online
services and web applications either for extortion
reasons, or for impairing and even disabling the
competition. This paper implemented that how much
these (DoS) attacks stand on a top role above on the
other attacks. We evaluate those results on four
attack categories as found in the KDD Cup 99
intrusion detection datasets, which is widely used
as one of the publicly available data sets for
network-based anomaly detection system such as
Intrusion Detection System (IDS).
