Schneier on Security
brothke writes "There is a perception in both the
private and government sector, that security, both physical and digital, is
something you can buy. Witness the mammoth growth of airport security
products following 9/11, and the sheer number of vendors at security
conferences. With that, government officials and corporate executives
often think you can simply buy products and magically get instant security by
flipping on the switch. The reality is that security is not something
you can buy; it is something you must get." Keep reading for the rest of Ben's review.

summary
The best articles from one of security's best
Perhaps no one in the world
gets security like author Bruce Schneier does. Schneier is a
person who I am proud to have as a colleague [Schneier and I
are both employed by the same parent company, but work in different divisions,
in different parts of the country]. Schneier on Security is a
collection of the best articles that Bruce has written from June 2002 to June
2008, mainly from his
Crypto-Gram
Newsletter, his
blog,
and other newspapers and magazine. The book is divided into 12 sections,
covering nearly the entire range of security issues from terrorism, aviation,
elections, economics, psychology, the business of security and much
more.
Two of the terms Schneier uses extensively throughout the book are intelligence and economics. From an intelligence perspective, he feels that Washington has spent far too much on hardware and other trendy security devices that create a sense of security theater. The security theater gives an aura and show of security, but in reality, has little real effect.
The lack of intelligence is most manifest with airports, which are a perfect example of misguided security. Schneier notes that current trends in US airport security requires that people remove their shoes, due to a one-time incident with shoe-based explosive. Such an approach completely misses the point. Also, Schneier notes that the attempt to create a no-fly list, by feeding a limited set of characteristics into a computer, which is somehow expected to divine a person's terrorist leaning, is farcical.
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.
Another recurring theme throughout the book is how the Bush administration has little by little eroded the Constitution, all in the name of fighting terrorism. Schneier notes that the brilliant framework the founding fathers created by creating divisions of power (executive, legislative, judicial) with checks and balances violates a basic unwritten rule, that the government should be granted only limited powers, and for limited purposes. Since there is a certainty that government powers will be abused.
Schneier observes that the USA PATRIOT is a perfect example of this abuse. The Constitution was designed and carefully outlines which powers each branch may exercise. While Schneier is best-known as a cryptographer and security expert, Schneier on Security also shows him to be a defender of the Constitution. In a number of essays in the book, he shows how unchecked presidential powers is bad not only for security, but for the preservation of democracy.
In chapter 8, on the topic of the economics of security, Schneier suggests a three-step program for improving computer and network security. He notes that none of them have anything to do with technology; they all have to do with businesses, economics, and people.
In chapter 9, on the psychology of security, Schneier writes that he tells people that if something is in the news, then they do not have to worry about it. He writes that the very definition of news is something that hardly ever happens. It's when something is not in the news, when it is so common that it is no longer news, drunk drivers killing people, domestic violence, deaths from diabetes, etc., that is when you should start worrying. And much of the terrorist threats that the Department of Homeland Security is spending tens of billions of dollars on, are those news threats, such as shoe bombers and liquid explosives that present very little real threat to the people of the US.
A fundamental theme of the book is that security is a trade-off. And far too many people have made the security trade-off without thinking if it is truly worth it. In essay after essay, Schenier challenges those assertions. Since 9/11, much has been given up in the name of terrorism, and that has been personal privacy and security. Schenier asks, has it been worth it?
Schneier on Security is an exceptionally important book that is overflowing with thought-provoking articles. Schneier gets above vague adages such as the war on terror and gets to the heart of the matter. His insight details what the real threats are, and what we should really be worrying about. The irony is that what Washington does is often the exact opposite of what should be done.
Much of the security carried out in the name of 9/11 has proven to be infective in the seven years since the attack. Schneier on Security is a manifesto of what should have been done, and what should be done. The book is eye-opening from the first page to the last. It lets you know that the next time you see grandma asked to take her shoes off by a TSA agent at the airport, why she is simply a bit player in the large security theater. And why spending tens of billions on a charade like that, makes that a tragedy of epic proportions.

The price is usually money, time, emotional energy, study, and perhaps reduced functionality.
Then again, that's probably the point of the book.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
And one who breaks security is like the one who alerts the king about wearing no clothes. You WILL get punished. You WILL be dealt with.
I saw this all the time at schools, jobs and like. People dont like smart people. People who intentionally find broken ideas and mechanisms will be dealt with, not glorified and congratulated. Highlighting a security problem means they have to put in the effort to fix what you brought to their attention, or threaten you to STFU.
If you are smart about security, keep your mouth shut. There's not much you can do, except yourself be a target.
If Chuck Norris tried to break Bruce Schneier's security, what would happen?
Fascism starts when the efficiency of the government becomes more important than the rights of the people.
Everything he talks about is just dealing with the symptoms. Terrorism is a symptom of very desperate people who feel that they're being shit on by someone.
I've been thinking about terrorism lately and its causes and its implementers. most terrorism is centered on what's happening in the Middle East. Now before someone accuses me of being anti-Islamic or racist or whatever, hear me out.
Terrorism is the result of very desperate people who have lost all hope and feel powerless. The Middle East and its people have been shit on for a couple of millennia; whether by western powers, other in the Middle East (Persians and Turks), Asians. These are people who have felt shit on by the World and there's nothing they can do about it. The creation of Israel was the straw that broke the camels back - so to speak.
To make a long story short, if we gave autonomy to the Middle east (Oil supplies be damned!), meaning pull out completely. I think terrorism would stop or at the very least, decrease dramatically.
I also disagree with folks who think that if we were to leave the Middle East, others would gain control of the Oil thereby sending us into a depression or putting our military and defense in jeopardy. It won't happen.
Amen.
I recently relocated to a rather rural area and I've met a lot of... shall we call them "simple" people. They look like country bumpkins, and many rarely leave the area, but several have surprised me with their insights.
One was an older man who worked construction his whole life. He once flew out to see his son's family in another state. While waiting to board his return flight he was sitting facing the key-pad door that led to the tarmac. He heard one person type "Beep... Beep... Beep... Bip-bip-bip." Then another. He realized that the six-digit code was three different numbers, followed by three identical numbers.
So he watched. After fifteen minutes he got the code. It was something like "264000." He wrote it on his boarding pass. When we handed the pass to the attendant at the gate she asked, "Sir, do you need this number?" He responded, "No, I don't need the code to your locked door over there." And then he boarded the plane.
A few minutes later two airport police officers came on the plane and asked him if he'd mind answering a few questions. He missed his flight (though they took mercy on him and put him on a later flight) while he was read the riot act. At no point did anyone thank him, nor did it seem that they were willing to find fault with their system or people who let out their ubersecret code.
He was wrong for hearing the code. He was wrong for watching the employees type the code.
I'd rather have someone respond than be modded up.
