Security analysis of software defined wireless network monitoring with sFlow and FlowVisor

Today's mobile and wireless network are growing faster in size and complex to measure the services. Security is one of the most important aspects for such complex network and needs to be monitored properly to provide early detection of security breaches and Denial of Service attack. Tools that measure such detection of network threats and monitors network services requires internal security in their own mechanism. This paper analyzes two of such monitoring and measurement tools: sFlow and FlowVisor for underlying Software Defined Wireless Networking (SDWN) environment by applying STRIDE threat model. This analytical study represents that, sFlow requires an external secure deployment environment to ensure security in data flow and data store for SDWN. FlowVisor comes with secured access control in data store wherein isolated flow slice requires mechanism that improve its security.
