Beyond Fear

pres (Preston Tollinger) writes "I picked up Beyond Fear: Thinking Sensibly About Security In an Uncertain World basically because it was by Bruce Schneier. I am sure most Slashdot readers know Schneier's name and his work. The problem is, this book probably isn't for you (but might be perfect for someone you know)." To find out what he means by that, read on for the rest of Tollinger's review, below. Beyond Fear: Thinking Sensibly About Security In an Uncertain World author Bruce Schneier pages 256 publisher Copernicus Books rating 7 reviewer Preston Tollinger ISBN 0387026207 summary A worthwhile introduction to real-world (not just computer) security, aimed at a literate but non-technical audience. The Book Beyond Fear is described very well by its subtitle: this book helps you think sensibly about security. Don't expect the highly technical material you have seen in Schneier's previous books, but rather the more accessible material, much like you might read in his monthly newsletter. That doesn't mean the book is breezy: In Schneier's wordy but well-written manner, he describes a five-step process to analyze any particular security system or practice. The process helps you make sure you understand what you are protecting, what the tradeoffs are, and whether, in the end if it is worthwhile to implement the system.

He then goes on to apply this method to a series of security issues while covering the various types of security and their weaknesses. For the most part this not a technical evaluation of the tools used, but rather an analysis for each example of what the security goals are and how the tools and technology achieve or fail to achieve those goals. Even more importantly, he deals with the tradeoffs inherent in any security system.

Schneier applies this method not only to the global issues that have come up since 9/11, from airline security to protecting government secrets, but also to personal issues, including tradeoffs in personal home security. By doing so, he takes principles which might be hard for some to understand in the abstract and makes it clear how they apply in situations almost everyone has thought about.

By drawing parallels, for instance, between how you might select a home alarm system to how you might evaluate the use of face recognition at the airport, Schneier shows that you don't have to be a security "expert" to think logically about security. He brings to the forefront the tradeoffs that you made in these personal choices; for example, the downside of dealing with deactivating an alarm system every time you come home. Then, in turn, he shows how you must consider the problem of people being falsely identified by the face recognition system at the airport.

Given this strong framework, he then uses his method to analytically and dispassionately tear apart most of the silly and stupid security methods (note my dispassion here) that have been put in place or considered in the past few years, from airline security methods to national ID cards. With a combination of funny yet pointed anecdotes, clear statistics and the occasional Harry Potter reference, Schneier uses his talent for cogent, rational explanation to show how people can think about security in the modern world, instead of simply panicking at every ominous news report.

To Read Or Not To Read So it sounds like a good book and probably would be for some, but there was not enough new content for me to make it worth my limited reading time. Perhaps due to my general interest in security or just because waiting in line at the airport has already given me a lot of time to think, but I have already considered most of the ideas Schneier raises in Beyond Fear. I own a shredder, but not an alarm system, because I have considered the risks and costs. I dislike the idea of a National ID card because I was already afraid of what someone might do who got access to it, and already monitor my credit report. I have written my local representative that while his recent bill to remove SSNs from insurance cards is nice, it's far too late (and how about just getting people to stop using SSN's as passwords?).

If this describes you, skip the book. However you might note above I didn't say this was a waste of my money. This book is soon going to find its way into hands of friends and relations who need to think about security. It is a great introduction to a way of thinking that is critical in a post-9/11 world. It should be required reading for members of Congress before any more security laws are passed based only on the need to do something instead of rational thought.

Summary If you think consciously about security, know who Schneier is, or have ever noticed (and complained) that many airport security measures make no sense, you probably don't need this book. If you have only considered this topic in general, though, and want a book to focus your thoughts, Beyond Fear will do that. Finally, if you have friends who don't yet think this way (admit it, we all do), get this book into their hands.

  1. Best example of how to speak about Security by StaticEngine · · Score: 4, Informative

    As a computer person, I don't consider myself a great conversationalist. And I agree that I've already thought about a lot of the issues Schneier brings up in "Beyond Fear."

    However, most "normal people" relate well to anecdotes, and general examples, and this book is full of them. Instead of trying to describe how 256 bit keys are safer than 64 bit keys to non-technical friends and relatives, I've learned lots of metahphors involving door locks, car theft, and every day risk assesment that will help me to get my point across a lot more clearly.

    I think this is the point of this book. It's not technical. It's Security for the Everyman.

      You provide the perfect example of a flawed extension of an analogy. Main battle tanks are designed to protect the occupants against enemy fire, not ramming. If a vehicle with the same mass as an Abrams were designed to protect against collision with more massive objects, it would be safer even if everyone drove them.

      Security works like that. You take something that works in one environment (Abrams on the battlefield getting shot at) and put it in a different environment, one it wasn't designed for (on the highway inevitably getting rammed) and it will fail in unexpected and unpredicatable ways (who knew that periscope, so essential for driving while being shot at, could detach and fatally injure the driver when the tank hits a brick wall doing 70 mph?)

    No. We aren't all born with the knowledge of obscure technologists here.

    Bruce Schneier is well known as an expert in security and cryptography. In particular, he is possibly best known for writing the bible of cryptography: Applied Cryptography.

    For other examples of his work, see here.

    No, the bible of cryptography is "Military Crytology" by William Friedman. Unfortunately, its not available thru Amazon. You'll have to go to Ft. Meade MD to get a copy. If you dont know who William Friedman is, find out.

    Well, lo and behold here comes Fare Inspection Shitwit to check my ticket, which I didn't have, through no fault of my own. Inspector Shitwit gives me a ticket ($90 fine) for failure to have a ticket on the streetcar. Naturally I rebuked him profanely and threw the ticket in the trash. I don't have any intention of dealing with such rubbish. But now, six months later, there's a warrant for my arrest which will never be served by the SFPD and I will be unable to renew my driver's license, which is expired, until a year after the incident.

    Some free, IANAL advice -- get your silly ass to a lawyer immediately. You should have just gone to court in the first place, but at least settle this before it really ruins your life down the road. They have these things called "computers" now and this matter won't go away.

    Having personally just gotten through dealing with something very much like what you describe, I can tell you that YOU are wrong. The "warrant" may expire, but the conviction will not. Eventually you will be held accountable, and it will just get more expensive for you down the road.

    There is no statute of limitations on avoiding court-ordered penalties. You now have a court-ordered penalty by virtue of your neglect in clearing the matter (therefore the "charge" of freeloading your Muni ride stood).

    I also live in SF, so you can't claim that "laws are different where I live".
