Your organization is planning to implement a new software-defined networking (SDN) solution to enhance network flexibility and efficiency. As a cybersecurity architect, you are tasked with specifying the security requirements for the SDN environment. The solution must comply with industry standards, ensure scalability, and maintain high availability without significantly increasing costs. Considering these constraints, what is the BEST approach to secure the SDN environment? (Choose one option)
A
Focus exclusively on encrypting network traffic within the SDN environment, disregarding the security of the SDN controller and underlying infrastructure to minimize costs.
B
Assume the SDN controller's default security settings are sufficient for all scenarios, avoiding any additional security configurations to ensure ease of deployment.
C
Implement a comprehensive security strategy that addresses the unique challenges of SDN, including securing the SDN controller, encrypting network traffic, and ensuring robust access controls, while also considering cost-effectiveness.
D
Apply the same security measures used in traditional networking environments to the SDN solution, ignoring the distinct architectural differences and potential vulnerabilities specific to SDN.
