DCS Deployment in SDN-Based Systems

Implementing DCS in a SDN-based system introduces several challenges and requires several enablers, which are discussed in this chapter. Our discussion does not answer all the questions related to the design and implementation of a practical DCS solution. Some additional challenges that are not discussed in detail are, for example, related to integrating DCS with existing cyber defence infrastructure and procedures. For example, acquiring current and reliable information on the security status of SDN components, especially in a multi-domain, federated environment, requires the implementation of effective mechanisms for the cooperation of network control systems and security operation centres (SOCs) that different organisations may manage.
