Hardening an SDN System (cont.)

• Harden the controller and the network elements (typical
  host hardening)


• Closely monitor controllers for suspicious activity


• Secure coding practices for all northbound applications
  requesting SDN resources


• Ability to validate flows in network device tables against
  controller policy


• Use Data Center Interconnect (DCI) protocols that can
  authenticate tunnel endpoints and secure tunneled
  traffic
