Adaptive cybersecurity ring for industrial wireless sensor networks

Abstract:

A system for providing cybersecurity for an industrial wireless sensor network (IWSN) including a plurality of devices in an industrial processing facility (IPF) that includes a computing device having a processor having an associated memory at one of the plurality of devices configured to implement an adaptive security ring. The adaptive security ring includes considering a plurality of current security considerations selected from a number of wireless hops for a first device of the plurality of devices to a root node in the IWSN, whether the first device is line powered or is battery powered, user' inputs for user defined criticality of the first device, and whether packet replay attacks are present for the first device by checking security headers and security statistics of packets received from other of the devices. Responsive to the current security considerations, a current cybersecurity level is automatically increased or decreased for the first device.
