The term “industrial control systems” refers to multiple different types of systems, networks, devices, and instruments involved with the control and automation of industrial processes. Such systems play a large role in streamlining business production practices and minimizing human error. Unfortunately, these systems face numerous security threats which have the potential to wreak extensive amounts of damage if they are successful. To better secure your industrial control system, make sure to implement protective measures against these common threats to industrial control systems.
Cyberattacks
Cyberattacks are one of the biggest threats that industrial control systems face. Since the convergence of IT and OT networks, the risk of cyberattacks on industrial control systems has grown substantially. By facilitating outside communication rather than operating in an isolated area, industrial control systems are far more vulnerable. Coupling this vulnerability with the fact that hackers continue to develop new, ever-evolving methods of attack, the need to implement extensive cybersecurity measures in industrial control systems is apparent.
Human Error
While industrial control systems are designed to help mitigate human error, they aren’t immune to it. Carelessness and failure to adhere to security protocol can leave industrial control systems even more vulnerable to malicious hackers than they already are. In some cases, security breaches are the result of simply inputting the incorrect setting. As such, it’s important to implement thorough training programs on the topic of maintaining security within the system and avoiding accidental breaches.
Inside Threats
Another common threat to industrial control systemsis insiders with malicious intent. In some cases, people do not need to exploit technical vulnerabilities within an industrial control system. If they already have inside access, all they need to do is exploit a business’s trust. As such, it’s important to exercise extreme caution when granting an individual access to an industrial control system. Once an individual has been granted access, make sure to document and monitor their activity.
