Whether it is the factory floor, an autonomous vehicle on the road, a connected surgery room, or a smart energy grid powering up a city, ubiquitous connectivity has exposed these industrial applications to unprecedented cyber threats. We are architecting a connected world where the network itself has been "weaponized." The increasing use of open standards in OT infrastructure, cloud connectivity, and multi-vendor-based highly complex solutions has seized the protection of using "little-known" protocols and technologies in industrial networks. Wireless technologies are providing a fast track to connectivity, but are also easier avenues (compared to wireline) for interception, code injection, and other forms of "man-in-the-middle" attacks (WSN).
Insider attacks and human errors can also cause havoc. The Stuxnet...
