Implementation and Analysis of an Improved PCA technique for DDoS Detection

摘要: With ever-increasing numbers of IoT devices becoming an essential part our everyday life, the risk compromised data security has grown many folds. SDN is state-of-the-art technology in networking domain. Combined with IoT, it provides centralized control to controller enabling better management traffic and prevention certain DDoS attacks layer 3 7 OSI model. But network makes vulnerable a new type attack which targets itself, thereby bringing entire down. This paper presents improved Principal Component Analysis (PCA) technique weighted principal components counter this attack. The partitioned into different subnets PCA applied each independently. proposed method helped targeted at or switch 95.24% accuracy contrast 92.3% previous scheme.
