SDN (Software Defined Network) separates control plane from data plane (forwarding plane) which leads programmability of network and scalability, flexibility of existed network. nevertheless, the reason that security requirements had never considered during the initial design of SDN brought various security issues. And this security issues includes vulnerabilities (such as unauthorized access, data modification and leakage) and attacks (for example, DoS (Denial of Service) and MIITM (Main-in-the-Middle attack)). In this paper, we proposed SEaaS (Security as a Service) which can provide security within SDN environment. Also, we suggest authentication mechanism between application and controller among the various services of SEaaS.
