That's a fairly in-depth question, but I'm happy to try to answer it.
I think there are a few elements. Certainly, the broader Internet and the broader aspect that we face in terms of technology is that it is a global supply chain, and there are a number of vulnerabilities that are in the software. There are a few things that we're pursuing.
The first one is really about building up the layers of security and the work that we're doing with various industries. In the context of the electrical infrastructure in Canada, one of the things we are looking for is to build in security, but not just in the products themselves. We're looking at it from a very similar approach to what would have been done in the safety world for the equipment as well, and now also how we can watch and monitor with them that equipment to make sure it's operating as expected? It's about building it to be as secure as possible, knowing that there's likely to be vulnerability. Then, how do you watch to make sure that it's operating as expected so that you can respond quickly? It's also about building in a response capability as well. In the industry, we call that “managed detection and response”, but it's really about knowing and understanding that nothing is invulnerable anymore. The systems are flawed no matter where they're built, and—
