That's a long question. I'll try to give a short response.
There's both the technological side and the human side to this. For example, you can have the absolute greatest technological solution, but if you have someone, say, from this committee walk to a computer and plug in a USB key with a piece of malicious code, you have just compromised the entire system. Not only do we have to have this technological safeguard, and you can see this on numerous reports—the most recent one would probably be the CSIS one that came out last week; we are getting attacked daily. If you want me to get you some statistics on how malicious.... Do you want statistics? Okay.
Again, you have to understand that these are estimates, because not everything is reported, and these are coming from places like McAfee and Google—
