Product Description
<>The Definitive Guide to Quantifying, Classifying, and Measuring Enterprise IT Security Operations Security Metrics is the first comprehensive best-practice guide to defining, creating, and utilizing security metrics in the enterprise. Using sample charts, graphics, case studies, and war stories, Yankee Group Security Expert Andrew Jaquith demonstrates exactly how to establish effective metrics based on your organization’s unique requirements. You’ll discover how to quantify hard-to-measure security activities, compile and analyze all relevant data, identify strengths and weaknesses, set cost-effective priorities for improvement, and craft compelling messages for senior management. Security Metrics successfully bridges management’s quantitative viewpoint with the nuts-and-bolts approach typically taken by security professionals. It brings together expert solutions drawn from Jaquith’s extensive consulting work in the software, aerospace, and financial services industries, including new metrics presented nowhere else. You’ll learn how to: • Replace nonstop crisis response with a systematic approach to security improvement • Understand the differences between “good” and “bad” metrics • Measure coverage and control, vulnerability management, password quality, patch latency, benchmark scoring, and business-adjusted risk • Quantify the effectiveness of security acquisition, implementation, and other program activities • Organize, aggregate, and analyze your data to bring out key insights • Use visualization to understand and communicate security issues more clearly • Capture valuable data from firewalls and antivirus logs, third-party auditor reports, and other resources • Implement balanced scorecards that present compact, holistic views of organizational security effectiveness Whether you’re an engineer or consultant responsible for security and reporting to management–or an executive who needs better information for decision-making–Security Metrics is the resource you have been searching for. Andrew Jaquith, program manager for Yankee Group’s Security Solutions and Services Decision Service, advises enterprise clients on prioritizing and managing security resources. He also helps security vendors develop product, service, and go-to-market strategies for reaching enterprise customers. He co-founded @stake, Inc., a security consulting pioneer acquired by Symantec Corporation in 2004. His application security and metrics research has been featured in CIO, CSO, InformationWeek, IEEE Security and Privacy, and The Economist. Foreword

 A ground-breaking book that all security managers should read August 9, 2007

I read Security Metrics right after finishing Managing Cybersecurity Resources, a book by economists arguing that security decisions should be made using cost-benefit analysis. On the face of it, cost-benefit analysis makes perfect sense, especially given the authors' analysis. However, Security Metrics author Andy Jaquith quickly demolishes that approach (confirming the problem I had with the MCR plan). While attacking the implementation (but not the idea) of Annual Loss Expectancy for security events, Jaquith writes on p 33 "[P]ractitioners of ALE suffer from a near-complete inability to reliably estimate probabilities [of occurrence] or losses." Bingo, game over for ALE and cost-benefit analysis. It turns out the reason security managers "herd" (as mentioned in MCR) is that they have no clue what else to do; they seek safety in numbers by emulating peers and then claim that as a defense when they are breached.
Fortunately, Security Metrics offers another solution. The book gives readers three sets of information: theory, metrics, and tools (concepts, not programs). The theory chapters (1 and 2) were so concise yet insightful I was tempted to underline every sentence. (I am not kidding.) Even the Preface made me glad to be reading the book when it associated "security ROI" with "the Macarena" and called it a "needless distraction." I laughed in agreement when I saw Andy call "security enablement" the "Abominable Snowman: it is rarely spotted, but legions of people swear it exists. After all, as my friend Dan geer puts it, 'You don't usually see airlines advertising how their planes fall out of the sky less often than their competitors.'" Why is that? My answer is simple: security is assumed and expected. Advertising anything else has no effect or makes people suspicious. I knew this book would be good.
The metrics chapters probably list hundreds of metrics you can extract verbatim and apply to your own environment. To the reviewer who wanted to reprint them in an appendix: they're called chapters 3 and 4. My main concern with the metrics was the focus on input-centric measurements instead of results. I would have liked to read more metrics on measuring whether security programs are working, rather than what techniques and tools are applied up front.
The tools chapters were helpful to anyone needing a statistics refresher. The visualization sections were especially helpful. (Feel free to dismiss yet another ignorant review from WB, who thinks a "review" means writing a few paragraphs after flipping through the pages of five books a day.) Andy's examples of turning lousy graphs and charts into information visualization vehicles should be followed by all managers.
Security Metrics is strengthened by the many stories from the author's consulting experience. I sensed that his techniques work and are not the product of the thought laboratory alone. I found his "Balanced Scorecard" approach to be interesting, especially to the degree it ties real metrics to business operations.
I had a few issues with terminology, such as using the term "threats" on p 231 when "attacks" is more accurate. (The football analogy is correct, however.) I semi-agreed with the author's suggestion to abandon "risk management" in favor of metrics-based approaches, but I didn't think two pages (4-5) were really enough to make the case. On p 264, threats are not risks, but they help instantiate risks. On pp 78-7, "risk of exploit" should be "ease of exploitation."
These are minor concerns, given the overwhelming concentration of practical and implementation-worthy pieces of information in Security Metrics. You must read this book if you care to measure security progress. Now we need Dan Geer to extend beyond writing wise forewords and articles into the world of his own book!

It's difficult to imbue a book on metrics with something other than academic theories, but Jaquith offers the working security professional a tangible lifeline. Nearly all of his suggested metrics are within easy reach, thanks to a commonsense approach and a tie-in to the instrumentation you're most likely to have in your data center.
Don't be scared off by the term "metrics," either; it's an easy read, chock full of amusing stories and turns of phrase (I thought my 80-year-old father was the only one who said "'pert near"). Jaquith focuses on the practical, from What Not to Draw (a graphics primer for charts and tables) to a Balanced Scorecard Makeover that actually looks achievable from outside the C-suite.
If your boss likes metrics, and your budget request is in jeopardy, you can't do better than this guide to making your case. Now, if only we had a practical, lightweight risk analysis methodology to go along with it ...
Should be in the hands of every security professional. May 16, 2007

The goal of security metrics is to replace fear, uncertainty, and doubt (FUD) with a more formalized and meaningful system of measurement. The FUD factor is the very foundation upon which much of information security is built, and the outcome is decades of meaningless statistics and racks of snake oil products. Let's hope that Andrew Jaquith succeeds, but in doing so, he is getting in the way of many security hardware and software vendors whose revenue streams are built on FUD.
One could write a book on how FUD sells security products. One of the most memorable incidents was in 1992 when John McAfee created widespread panic about the impending Michelangelo virus. The media was all over him as he was selling solutions for the five million PCs worldwide he said would be affected. The end result is that the Michelangelo virus was a non-event. Nonetheless, it was far from the last time that FUD was used to sell security.
The allure of FUD is that companies can spend huge amounts of money fighting nebulous digital adversaries and feel good about it. They can then put all of that fancy hardware in dedicated racks in their data center, impressing the auditors with the flashing lights giving off an aroma of security and compliance.
And that is the chaos that security metrics comes to solve. Security metrics, if done right, can help transform a company from a nebulous perspective on security to an effective one based on formal security risk metrics.
Security Metrics is a fabulous book that should be in the hands of every security professional. The book demonstrates that companies must establish metrics based on their unique requirements, as opposed to simply basing their requirements on imprecise industry polls, best-practices and other ill-defined methods.
So why don't companies do that in the first place? If security metrics can provide even a quarter of the benefits that Jaquith states, companies should run to implement them. Real security metrics require an organization to open up their security hood and dig deep into the engine that runs their security infrastructure. It necessitates understanding the internal requirements, unique organizational risks, myriad strengths and weaknesses, and much more. Very few companies are willing to dedicate the time and resources for that, and would rather build their security infrastructure on thick layers of FUD. History has shown that the security appliance of the month almost always beats a formal risk and needs assessment.
Chapter 1 lays out the problem with approaches that most companies take to risk management. The main problem is that traditional risk management is far too dependant on identification and fixing, as opposed to quantification and triage based on value. Quantifying and valuing risk is much more difficult than simply identifying, since the software tools used do not have an organization context or knowledge of the specific business domain.
Chapter 2 sets out the foundation of security metrics. The goal of these metrics are to provide a framework in which organizations can quantify the likelihood of danger, estimate the extent of possible damage, understand the performance of their security organizations and weigh the costs of security safeguards against their expected effectiveness.
The time has come for security metrics since information security is one of the few management disciplines that have yet to submit itself to serious analytical scrutiny. The various chapters provide many different metrics that can be immediately used in most organizations to address that.
The author defines various criteria for what makes a good metric. One of his pet peeves is the use of the traffic light as a metaphor for compliance. Jaquith feels that traffic lights are not metrics at all, since they don't contain a unit of measure or are a numerical scale. He suggests using traffic lights colors sparingly, and only to supplement numerical data or draw attention to outliers. He astutely notes that if your data contains more precision than three simple gradations, why dilute their value by obscuring them with a traffic light.
The chapter concludes on what makes a bad metric, defined as any metric that relies too much on the judgment of a person. These metrics can't be relied on since the results can't be guaranteed to be the same from person to person. Also, security frameworks such as ISO-17799 should not be used for metrics. The book also tackles the sacred cow of risk management, namely ALE (annualized loss expectancy), and how it is significantly misused and misunderstood in the industry.
The book states that in developing metrics, there must be formal collaboration between the business units and the security staff. This collaboration serves to increase awareness and acceptance of security. In addition, it ensures that security requirements are incorporated into the lifecycle early on. This is needed as business units generally have no clue as to what the needed security requirements are.
Chapter 5 is a short course on analysis techniques and statistics. The author quotes George Colony who stated that "any idiot can tell you what something is. It is much harder to say what that thing means". With that, the book details a number of techniques for analyzing security data (average, median, time series, etc.) and how each one should be used.
Chapter 6 is about visualization and notes that most information security professionals have no real idea how to show security, both literally and figuratively. Part of the problem is that security is proliferated with esoteric terminology and concepts, and the lack of understanding risk management amongst the masses. Part of the reason for this difficulty in sharing the security message with management is that many security practitioners lack simple metaphors for communicating priorities. This is compounded by the fact that the message is often focused exclusively on technical security issues, as opposed to the underlying business issues, which is was management is concerned with. The chapter is invaluable as it weans one off the malevolent pie chart and traffic light PowerPoint presentation.
Marcus Ranum notes that people seem to want to treat computer security like its rocket science or black magic. In fact, computer security is nothing but attention to detail and good design. FUD is all about emphasizing the black magic aspect of hackers and other rogue threats. Metrics are all about the attention to detail that FUD lives to obfuscate.
Security Metrics: Replacing Fear, Uncertainty, and Doubt is one of the more important security books of the last few years. Jaquith turns much of the common security wisdom on its head, and the world will be a better place for it. Security metrics are a necessity whose time has come and this invaluable book shows how it can be done.

Security Metrics condenses a lot of useful knowledge on data analysis, visualization, and automated calculation. I've successfully applied Jaquiths's concepts over the past month with fantastic results. The results have helped me illustrate my data in more meaningful ways and also direct my research with more insight. Highly recommended!
Metrics from a practical perspective - a great guide! May 24, 2007

Mr. Jaquith's down to earth style and sense of humor make reading this book a very pleasant experience. It is an excellent first book in this field, and I predict it will become a standard. The security field needs this kind of critical insight to promote a higher level of professionalism and service. There are many great ideas in these pages that should be useful whether you're just starting a security program, overhauling an old program, or just want to try something new for your next project. The treatment of mathematics is right on the mark - defensible without being so rigorous it loses people. I'm going to be keeping this book within arm's reach for a long time.
