An OpenFlow-Based Approach to Cloud Architecture for Detecting Network Security Events

With the rapid development of computer technology and the rapid expansion of network scale, the security requirements of network resources have also increased. The design and optimization of the method for detecting network security events to adapt to the characteristics of the cloud environment is the basis for the effectiveness of OpenFlow, and is a key issue in the cloud architecture approach to detecting network security events. The objective of this paper is to investigate the cloud architecture approach to detecting network security events based on OpenFlow. The background of cloud security research based on OpenFlow technology and related existing research work are first introduced, then background knowledge including SDN and OpenFlow is presented, and the design of OpenFlow-based cloud architecture approach to detecting network security events is proposed, using DES encryption algorithm as well as SDN network technology to solve network security problems. The intrusion detection results are analyzed and experiments show that vNID has a high packet capture capability.
