Sure. I'm happy to do that.
In terms of the maritime domain, specifically, the primary cyber-threat I would underline is the threat to merchant vessels, in fact. They are often more vulnerable to hacking for a variety of reasons. There's a tendency to use more outdated software and more dated systems on some of those ships. They sometimes were not designed with cybersecurity in mind the way systems are designed now, certainly within the military context, but even more generally for the private sector now. This is something that is present in people's minds.
From a maritime security perspective, this obviously presents a range of challenges: financial loss for companies, potentially, depending on how systems are manipulated; loss of an ability to track a course that can result in lost goods or environmental crises of one kind or another; and the risk of manipulating a vessel's automatic identification system or electronic charts, depending on what systems they're using.
All of these things are taken very seriously by the private sector and are something they monitor now, but because of the nature of commercial shipping, there are many vessels still on the oceans that aren't fully up to date with software and hardware that would give them the robustness we would like.
With regard to threats to military vessels, there are certainly nations out there, Russia and China primarily, that have the capability to effect a range of systems. What I would say about that is that it is a known threat, something we take very seriously, and something we are conscious of when we're designing or upgrading our own systems. Keeping, as much as possible, ahead of that threat curve is very much a part of the work we feed into from the intelligence command perspective.
