Thank you, sir.
From the NORAD point of view, in our lane we're still concerned about the approaches. I would put air and maritime ahead of cyber, because that's our directed mandate, and to us it's a no-fail mandate.
In terms of cyber, in doing our maritime and aerospace mandate we have to operate with cyber systems, and we have to operate in a contested cyber environment. In those terms, we have to stay ahead of the threats in trying to outpace the threats so that our systems are not vulnerable to cyberattacks.
In terms of chemical, biological, radiological, and nuclear agents, those are agents that could be transported by air or in maritime approaches towards North America. We try to gather as much intelligence as we can on these potential agents, but for us it's about the approaches by air or by sea, whereas for CJOC it's by land.
In terms of the defence of the north, we think of the north in three sectors: safety, security, and defence. Safety is mainly the realm of maritime safety, of course, and air safety, and then there is the realm of the civilian agency and the search and rescue system. For security, it's more in the law enforcement agency realm that we're there in support, given the capabilities we have. Finally, on defence, when we talk of defence from the NORAD point of view, it's aerospace defence and maritime warning.
