Enabling Situational Awareness in Operational Technology Environments through Software Defined Networkin

Abstract:

Network situational awareness has long been associated with the task of aggregating system logs to determine activity and events ongoing in the network. However, this current method of obtaining situational awareness does not clearly address the mission of a facility or organisation, the key customers at stake, and the real-time statuses of the critical infrastructures. Soft-ware-definednetworking provides the capability of allowing the collection of system information of deployed network elements and enabling a global view of the network topology, with near real-time knowledge of network activities, allowing for key points of the network to be identifiedand secured appropriately.
