A survey for restricting the DDOS traffic flooding and worm attacks in Internet

DoS attacks are significant issues for the Internet. With huge need on internet service provided using large application server, Denial of Service (DoS) attack is developed into a key security issue in the network service provisioning. Flooding attack is one of the major DoS attacks, floods the network traffic abnormally to disturb the internet services which is rendered to users. In addition, worm attack is an impeding feature on internet peer servers on providing services to the users. Worm attack self replicates and distribute the malware across the network by its own. However, the worm detection schemes are not able to scan and detect exponentially rising abnormal traffic patterns. It is more susceptible in providing the security to the internet peer servers. DoS flooding and worm attack resistance schemes are not easy to implement because it needs large number of cooperating and monitoring activities on the services provided to the users. So, Integrated Quantum Flow and Hidden Markov Chain Approach (IQF-HMC) is designed to restrict the DDOS traffic flooding and worm attacks in internet.
