Cloud Computing is the revolutionary technology of the current era. It allows the end user to consume the cloud based services from anywhere and at anytime over the internet. This technology is surrounded by several attacks, threats and risks. One among the several attacks is Distributed denial-of–service (DDoS), which is often reported by cloud service providers. DDoS has severe effects from the performance degradation of the application to complete shutdown of the service. In this paper we proposed a secure defence mechanism based on machine learning for defence against DDoS attack. Our proposed approach makes use of four machine learning algorithms such as Random Forest, Decision Tree, K-Nearest-Neighbor and Support Vector Machine along with optimizing some of the crucial hyperparameters for these machine learning algorithms that can effectively increase the accuracy of our proposed system. The hyperparameter optimization is performed by Bayesian Optimization technique in our approach, which converges to the optimal set of hyperparameters rapidly in contrast with other available hyperparameter tuning techniques such as GridSearchCV and RandomSearchCV. The performance results were compared and it was observed that our proposed approach reduces the processing time, increases the classification accuracy, increases the true positive rate at the same time reduces the false positive rate.
