As the Internet of Things gains momentum with millions of devices connected to one another, it has become more challenging to secure these devices and services given their increasing complexity. Over the last few months, we have already witnessed attacks to critical infrastructure around the world from Triton infiltrating the control and safety systems of an oil and gas plant to NotPetya shutting down production at a pharmaceutical factory. We can no longer ‘simply’ connect our devices without building in end-to-end security because the financial toll is not the only risk but the risk to human lives and property is too great.
The Triton attack on the control and safety systems of an industrial plant brought to the forefront system vulnerabilities in critical infrastructure even when they are designed with failsafe controls. Attackers used sophisticated malware to remotely control a safety control workstation. Some controllers accidently triggered failsafe mode as the attackers tried to reprogram them.
