Abstract: Denial of Service (DoS) is one of the most effective and strong attacks in cyberspace. They tend to be frequent due to which optimization is being looked at. Over time various methods have been developed and proposed to reduce this problem but with the advent of high power and high ability devices the strengths of these attacks have also increased. In such cases, it is highly imperative that a mechanism be introduced in a manner that doesn’t consume too many resources by itself and yet provides similar means of security. Flooding attacks are a hindrance to the most basic of security principles, the CIA triad. Availability of resource is highly impaired in such attacks and can be seen as a cause of distress to quite a few. This study presents a threshold based queue management system which creates a virtual upper bound on the resource allocation so that the entirety of the resources is never exhausted. Thereby, giving adequate reaction and response time to the high influx of packets. Proper recognition of malicious packets will result in proper marking of the sender, thereby helping the decision of dropping of packets. Furthermore, appropriate studies using a modular simulator have been made and the results show the efficiency of the proposed method in the aforementioned scenarios.
