A bit of some of that might touch on some classified issues, but I can certainly talk about it and hope I answer your question fully.
There are a few things. Typically, what we're talking about here is that the way the Internet routes itself is that it works on what is the cheapest route, usually meaning fastest. You can pretend to be the cheapest route and fastest, which forces the Internet to direct across it. The technique for that is called “BGP hijacking”, but I won't go into all the techy grossness of it.
That's one of the things that we've been working on in partnership with telcos. I talked about innovation before, and we do look at ways to innovate and work with our telcos to detect this type of activity, and moreover, to ask what are the defensive ways we can do things to prevent this?
It isn't something that happens a lot, but it is something that can happen and it's something that we're looking for. We're looking for ways to mitigate and defend against it, but at the same time, though, not reduce the reliability of the Internet.
It is something where you're talking about big shifts, so it is a bit of a concern. Really, you're talking about being able to mass all the data that's going from one place to another, so encryption is a great defence against that.
With our apps, right now for example we are on an encrypted Zoom channel. You can't publicly just tap into this; you have to be able to sign in, and so on. There's encryption there. When I send a message over any of the messaging apps, and so on, that's encrypted.
Our websites are all encrypted now as well for the government, and hopefully, more and more commercial sites are fully encrypted. That immediately puts a barrier to actually using that information for anything, other than getting a whole bunch of encrypted data that you can't do anything with.
Those are some of the defences.
