Want to Know About Security? Read This Guy

Slashdot has a post up reviewing Schneier on Security, and it sounds like he confirms a number of things I’ve been thinking for a while now. Check out the excerpt from Slashdot:

Schneier therefore feels that the only way to effectively uncover terrorist plats is via intelligence and investigations, not via large-scale processing of everyone. Intelligence is an invaluable tool against terrorism, and the beauty of it is that it works regardless of what the terrorists are plotting. The bottom line according to Schneier in the book is that too much of the United State’s counterterrorism security spending is not designed to protect us from the terrorists; but instead to protect public officials from criticism when another attack occurs.

Schneier also astutely notes that for the most part, security is not really so much of a technical issue, rather one of economics. A perfect example he gives is that of bulletproof vests. Since they are so effective, why doesn’t everyone wear them all of the time? The reason people don’t is that they do not think they are worth the cost. It is not worth the money or inconvenience, as the risk of being shot for most people is quite low. As a security consumer, people have made the calculation that not wearing a bulletproof vest is a good security trade-off. Schneier also notes that much of what is being proposed as national security is a bad security trade-off. It is not worth it and as consumers, the public is being ripped off.
