One-Third of Industrial Networks Connected to Internet: Study

Very scary indeed.

Many industrial and critical infrastructure systems are connected to the Internet, and the operational technology (OT) networks of some organizations have already been compromised, according to a new study from industrial security firm CyberX.

What makes the CyberX study interesting is the fact that it’s not based on a survey. Instead, the company used data obtained after passively monitoring traffic from 375 OT networks over the past 18 months. The organizations whose networks have been analyzed are from a variety of sectors – including manufacturing, energy and utilities, oil and gas, and pharmaceuticals and chemicals – in the United States, Europe and the Asia-Pacific region.

Organizations have often downplayed the risks associated with the presence of vulnerable industrial control systems (ICS) on their networks, claiming that devices are isolated, or air-gapped, and cannot be accessed remotely from the Internet.

However, CyberX’s study revealed that roughly one-third of organizations had industrial networks connected to the public Web. These systems are often accessible remotely for convenience, including for remote management, performing software updates, and even web browsing and email from the OT network.

Over networking is the problem. I've worked in places where people who deal with customer accounts are on the same network as developers, and internet.
Sounds ludicrous I know, but its a fact.
Over the years networks get bloated, everyone wants internet access and the IT guys just have to try to keep it working.

Just how dumb can you be? It's almost like they want to be hacked.
