The importance of the DDoS issue and the rise in the frequency, sophistication, and power of assaults have prompted the development of several prevention techniques. Each suggested preventive measure differs from the others in certain specific benefits and drawbacks. In this study, we categorise the many defences against potential DDoS assaults that have been put forth in the literature and evaluate the advantages and disadvantages of each defence. It is preferred to consider that the number of maximum continuous DoS attacks in both the S-C and the C-A channels is bounded because of the cost effect of attacks. In this project on Distributed denial of service (DoS) attacks in cyber-systems, DoS attacks exist in between the sensor and controller communications and the controller-to-actuator communications. Then, a successful security control technique is developed to counter two-channel DoS attacks, fully utilising the hardware to guarantee that control inputs are periodically captured during each time slot. A security controller that includes both the present and future control inputs is designed at the same time. The addressed CPS can be stable under 2-channel DoS attacks while maintaining control effectiveness under an appropriate security control strategy and security controller. Last but not least, simulations and tests are provided to show the viability of the suggested active security control approach.
