It is sort of interesting that in our society this days we are very quick to apply the term 'war' to places where thare are no actual wars, and loath to apply the term 'war' when we are actually fighting wars.

If you ask amateurs to act as front-line security personnel, you shouldn't be surprised when you get amateur security.

I tell people: if it's in the news, don't worry about it, because by definition, news is something that almost never happens.

Metadata equals surveillance; it's that simple.

ID can be hijacked, and cards can be faked. All of the 9/11 terrorists had fake IDs, yet they still got on the planes. If the British national ID card can't be faked, it will be the first on the planet.

History has taught us: never underestimate the amount of money, time, and effort someone will expend to thwart a security system. It's always better to assume the worst. Assume your adversaries are better than they are. Assume science and technology will soon be able to do things they cannot yet. Give yourself a margin for error. Give yourself more security than you need today. When the unexpected happens, you'll be glad you did.

People often represent the weakest link in the security chain and are chronically responsible for the failure of security systems.
