Security or Liberty? Both!,
This review is from: Beyond Fear: Thinking Sensibly About Security in an Uncertain World (Hardcover)
I first read about Bruce Schneier in an eye-opening article by Charles Mann in the September, 2002 issue of The Atlantic Monthly. It seems that you don't have to make the false choice everyone is agonizing over between security and liberty. You can have both.
Schneier's book expands on the ideas in the article. Although Schneier is a technology fan and it is his livelihood, he realizes that sometimes a live security guard can provide better security than cutting-edge (but still fallible) face-recognition scanners, for instance. He explains why national ID cards are not a good idea, and how iris-scanners can be fooled.
These are ideas for security on a large scale, for airports, nuclear and other power plants, and government websites. For security on an individual or small business scale, try Art of the Steal by Frank Abagnale. But even if you don't run a government, Beyond Fear is a fascinating read about how your government is making choices (and how they SHOULD be making choices about your security and about your rights.
