Below is the list of blog posts with the “Critical infrastructure” tag.

The default advice for any system running an unsupported operating system is simple: replace it. Upgrade to a supported platform. Move to modern hardware. Problem solved. It’s good advice in theory. As with many other things in life however, in practice it ignores everything that makes legacy infrastructure hard to deal with in the first place. For organizations running Windows XP, Server 2003, or other legacy 32-bit Windows systems, "just upgrade" is often the most expensive, disruptive, and operationally risky option on the table.

Somewhere in a hospital basement, an MRI machine hums along on Windows XP. Down the road, a CNC controller on a factory floor runs Windows Server 2003. Across town, a municipal utility manages water treatment with software that hasn’t seen an update since the second Bush administration. These aren’t edge cases. They’re everywhere — and they represent one of the most underestimated risks in enterprise security today. Still here, still running It would be reasonable to assume that operating systems from the early 2000s have no place in a modern network.

European electric power system operators supply around 2800 TWh of electricity per year and manage around 10 million kilometers of power lines - more than ten round trips to the Moon. Such electric travel is impossible without electric substations, an essential component of a power grid. Its automation becomes ultimately digitalized, so requires proper monitoring both for operational and security purposes. Let’s take a look at how a unified log collection pipeline embeds into power automation systems and helps make sure the lights stay on.

Historically, seaports have played a crucial role in a state’s development, and interruption in their services has a significant impact on economics. So, it’s no surprise commercial ports are regarded as a critical transport infrastructure. One of the most significant challenges ports face today is ongoing digital transformation. The majority of tasks carried out across a port utilize autonomous and partially automated systems, including those for managing port access, vessel berthing (bridges, locks, gates, etc.

With open war in Europe for the first time since 1945, nations across the continent have been busy shoring up their information security defenses. The European Union is stepping up to the plate, releasing a Cyber Defence Policy to, in its words, "boost EU cyber defence capabilities and strengthen coordination and cooperation between the military and civilian cyber communities." However, bolstering cyber defenses across a collection of countries, home to 450 million people and spanning four million square kilometers, is no easy feat.

In light of recent news stories about possible cyberattacks on the U.S. power grid, we are inclined to ponder over precautions we can take to prepare for such a scenario. If you are in the public utilities industry, this blog post is for you. But, if you’re not, don’t worry. We will cover some basic principles you can follow to get your organization ready before such a cyberattack occurs.
