Beautiful Security 81

brothke writes "Books that collect chapters from numerous expert authors often fail to do more than be a collection of disjointed ideas. Simply combining expert essays does not always make for an interesting, cohesive read. Beautiful Security: Leading Security Experts Explain How They Think is an exception to that and is definitely worth a read. The book's 16 chapters provide an interesting overview to the current and future states of security, risk and privacy. Each chapter is written by an established expert in the field and each author brings their own unique insights and approach to information security." Keep reading for the rest of Ben's review.

summary An eye-opening book that will challenge you
A premise of the book is that most people don't give security much attention until their personal or business systems are attacked or breached. The book notes that criminals often succeed by exercising enormous creativity when devising their attacks. They think outside of the box which the security people built to keep them out. Those who create defenses around digital assets must similarly use creativity when designing an information security solution.

Unfortunately, far too few organizations spend enough time thinking creatively about security. More often than not, it is simply about deploying a firewall and hoping the understaffed security team can deal with the rest of the risks.

The 16 essays, arranged in no particular theme, are meant to show how fascinating information security can be. This is in defense to how security is often perceived, as an endless series of dialogue boxes and warnings, or some other block to keep a user from the web site or device they want to access. Each of the 16 essays is well-written, organized and well-argued. The following 4 chapters are particularly noteworthy.

Chapter 3 is titled Beautiful Security Metrics and details how security metrics can be effectively used, rather than simply being a vehicle for creating random statistics for management. Security metrics are a critical prerequisite for turning IT security into a science, instead of an art. With that, author Elizabeth Nichols notes that the security profession needs to change in ways that emulate the medical professional when it comes to metrics. She notes specifically that security must develop a system of vital signs and generally accepted metrics in the same way in which physicians work. The chapter also provides excellent insights on how to use metrics, in addition to high-level questions that can be used to determine how effective security is within an organization.

Chapter 6 deals with online-advertising and the myriad problems in keeping it honest. Author Benjamin Edelman observed a problem with the online supply chain world, as opposed to brick and mortar (BAM) world, in that BAM companies have long-established procurement departments with robust internal controls, and carefully trained staff who evaluate prospective vendors to confirm legitimacy. In the online world, predominantly around Google AdSense, most advertisers and advertising networks lack any comparable rigor for evaluating their vendors. That has created a significant avenue for online advertising fraud, of which the online advertising is a victim too.

Edelman writes that he has uncovered hundreds of online advertising scams defrauding hundreds of thousands of users, in addition to the merchants themselves. The chapter details many of the deceptive advertisements that he has found, and shows how often web ads that tout something for free are most often far from it.

Chapter 7 is about the PGP and the evolution of the PGP web of trust scheme. The chapter is written by PGP creator Phil Zimmerman, and current PGP CTO Jon Callas. It has been a long while since Zimmerman has written anything authoritative about PGP, so the chapter is a welcome one. Zimmerman and Callas note that while a lot has been written about PGP, much of it contains substantial inaccuracies. The chapter provides invaluable insights into PGP and the history and use of cryptography. It also gives a thorough overview of the original PGP web of trust model, and recent enhancements bring PGP's web of trust up to date.

Chapter 9 is one of the standout chapters in the book. Mark Curphrey writes about the need to get people, processes and technology to work together so that the humans involved in information security can make better decisions. In the chapter, Curphrey deals with topical issues such as cloud computing, social networks, security economics and more. Curphrey notes that when he starts giving a presentation, he does it with the following quotation from Upton Sinclair — "it's difficult to get a man to understand something when his salary depends on him not understanding it." He uses the quote to challenge listeners (and readers in this case) to question the reason why they are being presented the specific ideas, which serves as a reminder of common, subtle biases for thoughts and ideas presented as fact.

In its 250 pages, Beautiful Security is both a fascinating an enjoyable read. There are numerous security books that weigh a few pounds and use reams of paper which don't have a fraction of the real content that Beautiful Security has. With other chapters from industry luminaries such as Jim Routh, Randy Sabett, Anton Chuvakin and others, Beautiful Security is a required read.

For those that have an interest in information security or those that are frustrated by it, Beautiful Security is an eye-opening book that will challenge you, and change the way you think about information security. It is a good book for those whose who think information security is simply about deploying hardware, and an even better book for those who truly get information security.
