CASP+ Definitions: Open SDN
Open SDN (Software-Defined Networking) is a networking approach that utilizes open source software to enable the dynamic management and control of network resources. In an Open SDN environment, the control plane and data plane of the network are separated, allowing for centralized management and programming of network devices through a software controller. This allows for greater flexibility and agility in the network, as well as the ability to more easily integrate with other systems and technologies.
From a cybersecurity perspective, Open SDN can improve security by enabling greater visibility and control over network traffic, as well as allowing for more fine-grained security policies to be implemented. Additionally, the use of open source software can potentially lead to more secure and transparent code, as it is subject to review and contributions from a wide community of developers. However, as with any technology, proper configuration, monitoring, and management of Open SDN systems is necessary to ensure they remain secure and resilient against attacks.
