A network intrusion detection system in cloud computing environment using dragonfly improved invasive weed optimization integrated Shepard convolutional neural network.

In cloud computing, the resources andmemory are dynamically allocated to the user based on their needs. Security is considered as a major issue in cloud as the use of cloud is increased. Intrusion detection is considered as a significant tool to develop a reliable and secure cloud environment. Performing intrusion detection in cloud is a difficult task because of its distributed nature and extensive usage. Intrusion detection system (IDS) is widely considered to find the malicious actions in network. In cloud, most conventional IDS are vulnerable to attacks and have no capability for maintaining the balance between sensitivity and accuracy. Thus, we proposed an effective dragonfly improved invasive weed optimization-based Shepard convolutional neural network (DIIWO-based ShCNN) to detect the intruders and to mitigate the attacks in cloud paradigm and are more feasible to detect the intruderswith ShCNN. The proposed method outperforms the existingmethod with maximum accuracy of 0.960%, sensitivity of 0.967%, and specificity 0.961%, respectively. [ABSTRACT FROM AUTHOR]
