DDoS Attacks and Impacts on Various Cloud Computing Components

Özet

Cloud computing is the subject of the era and is the current keen domain of interest of organizations due to its promising opportunities and catastrophic impacts on availability, confidentiality and integrity. On the other hand, moving to cloud computing paradigm, new security mechanisms and defense frameworks are being developed against all threats and malicious network attacks that threaten the service availability of cloud computing for continuity of public and private services. Considering the increasing usage of cloud services by government bodies poses an emerging threat to e-government and e-governance structures and continuity of public services of national and local government bodies. IoT, industry 4.0, smart cities and novel artificial intelligence (AI) applications that require devices to be connected in ever present cloud platforms, provide an increasing wide range of potential zombie armies to be used in Distributed Denial of Service (DDoS) attacks which are amongst the most critical attacks under cloud computing environment. In this survey, we discuss in detail the classification of DDoS attacks threatening the cloud computing components and make analysis and assessments on the emerging usage of cloud infrastructures that poses both advantages and risks. We assert that considering various kinds of DDoS attack tools, proactive capabilities, virtual connecting infrastructures and innovative methods which are being developed by attackers very rapidly for compromising and halting cloud systems, it is of crucial importance for cyber security strategies of both national, central and local government bodies to consider pertinent pre-emptive countermeasures periodically and revise their cyber strategies and action plans dynamically.
