The advent of IoT has seen a vast inventory of infrastructure and machines embedded with advanced internet-enabled sensors and other technology. Along the way, a whole new arena of cyberthreat has emerged, and a hugely broadened attack surface.
These assets – collectively known as Operational Technology (OT), form the backbone of our societies and businesses. From power plants to road networks, industrial machinery to portable equipment, the era of connected OT creates innumerable opportunities for hackers to cause devastating disruption.
Keeping your OT network secure requires a very different approach than the equivalent for IT security. While adopting advanced technologies like AI from big-name vendors may seem like the reassuring answer, this alone is only one piece of the puzzle.
For BearingPoint, a holistic approach to OT security is essential – one that addresses each of these critical aspects:
Ensuring the OT infrastructure of your business is as secure as possible means optimizing your control of it. But how do you control a network that may include many thousands of nodes, and potential points of weakness?
Once your business has in place everything it needs to control your assets, and access to them, you can begin the process of actively protecting them. BearingPoint recommend a five-step approach to OT security that progressively increases the security level of your infrastructure, without incurring risk:
BearingPoint have worked extensively for global businesses to help them better control and protect their OT assets.
In the automotive arena, we assist our clients to reach a more secure ecosystem for vehicle off-board management and applications. This has been done by facilitating the necessary steps to comply with UN ECE R155 (cybersecurity), R156 (software updates) regulations and ISO/SAE 21434.
For one such client, we collaborated on and developed a management system for off-board platforms, prepared them for a cybersecurity audit and covered the latest software updates. We supported them in coordinating cybersecurity activities at the organisation level, with a thorough definition of processes, responsibilities and measures so that future attack surfaces would have strong coverage.
With an ever-increasing attack surface that can be targeted, mitigating threats to your OT security has never been more pressing. Securing your operational technology against attack should be seen as fundamental to business continuity.
BearingPoint advise security teams in medium-sized and large companies on how to deal with OT security threats. Most importantly, we show you how to implement a holistic approach that spans more than simply installing standard or even more sophisticated technology fixes.
