System integrators’ role in the OT cybersecurity crisis
Whether it’s the shift toward remote work or the growing importance of digital business, trends that have been around for years have only been accelerated by the COVID-19 pandemic. This holds true for the digital transformation, bringing operational efficiencies at the cost of increased cyber risk to our critical infrastructure we’re only beginning to see the true effects of.
System integrators’ role in the OT cybersecurity crisis
Whether it’s the shift toward remote work or the growing importance of digital business, trends that have been around for years have only been accelerated by the COVID-19 pandemic. This holds true for the digital transformation, bringing operational efficiencies at the cost of increased cyber risk to our critical infrastructure we’re only beginning to see the true effects of.
Ignoring cyber risk is dangerous to society and your bottom line
To anyone working in cybersecurity, it is not news that just about every critical infrastructure industry is significantly behind on their path toward cybersecurity maturity. There continues to be a fundamental friction between the estimation of cyber risk and the short-term thinking of today’s quarterly budgetary decisions.
Improve legacy critical infrastructure protection
Distributed network protocol 3.0 (DNP3) is the second most-widely used serial communications protocol in industrial control systems (ICS), after Modbus. As EPRI (Electric Power Research Institute) mentioned in a 2019 technical update: “it is the most widely used utility communications protocol in North America” and is used to enable communication between components in process automation systems.
System integrators and serial communication monitoring: Why it matters
Historically, industrial control systems (ICS) could exist as a closed-loop, with an air-gapped network and a solid physical security program insulating them from the outside world. An operator could trust the integrity of their operations based on process outputs, and when processes broke down maintenance was brought in to locate and fix the issue. Not to say it was a simple time (it wasn’t), but the internet and digital transformation has changed the game at an ever-accelerating pace.
