CASP+ Definitions: Hybrid SDN
Hybrid SDN (Software-Defined Networking) refers to the use of both traditional and software-defined networking techniques in a network architecture. In a hybrid SDN environment, the control and data planes are partially decoupled, and the network can be managed using a combination of centralized controllers and traditional networking protocols.
In a hybrid SDN architecture, traditional network elements such as routers, switches, and firewalls can be managed by a centralized controller, while other network elements such as servers and storage devices are managed using traditional networking protocols. This approach allows organizations to take advantage of the benefits of SDN, such as centralized management and automation, while still maintaining their existing network infrastructure and applications.
From a cybersecurity perspective, hybrid SDN can offer benefits such as improved visibility and control over network traffic, simplified network management, and faster response times to security threats. However, it is important to ensure that proper security controls are in place to protect the SDN controller and other network components from cyber threats.
