and control of information security risks have emerged as a primary mean by which organizations secure information infrastructure. Key assets are identified and protected as a part of risk management strategy. In this process, commonly Denial of Service (or DoS) attacks are overlooked. DoS service is traditionally not considered as information security risk, hence the treatment of that remains low priority. But in the recent past, several such attacks had made high profile business’s web servers unavailable or un-accessible for considerable period of time, which consequently caused monitory and reputational losses. Hence now there is a substantial need to consider DoS attacks as a potential risk for information security and its assessment and treatment should be included in organization’s risk management process. This paper examines the major forms of DoS attacks that are lodged on critical network infrastructure of an organization, targeting the availability and access of its critical business and IT Services and further how the risk of such attacks can be reduced or mitigated through risk management process.
