Announcing Scientia Securitatis: The Science of Security

After 34 years across nearly every security domain that exists — armed physical security at an overseas critical installation, combat force protection, security in a regional hospital’s psychiatric ward, payment-card industry compliance, armed maritime contracting off the East African coast, and a return to enterprise cybersecurity that has occupied the past decade — I have written the book I wish someone had written when I started.
Scientia Securitatis: The Science of Security — Theory, Frameworks, and Practice is available now.
The gap this book is intended to fill
The security profession does not lack books. Walk into any bookstore, scan any conference vendor floor, search any retailer’s security category, and you will find more material on cybersecurity, physical security, risk management, military theory, criminology, intelligence analysis, and organizational resilience than any single practitioner could read in a career. The field is overwhelmed with information.
What it lacks is integration.
Each security domain has developed its own vocabulary, its own frameworks, its own bestsellers, its own consultants. Each domain — when traced carefully to its analytical roots — is reaching for the same underlying concepts the next domain over named differently. Practitioners in physical and cybersecurity are working on the same analytical problems and rarely speak to one another. When they do, they discover that they have been duplicating each other’s work for decades.
Scientia Securitatis is an attempt to make that recognition the starting point of professional practice rather than an accident a few practitioners stumble into late in their careers.
What’s in the book
The book runs to 525 pages across 11 chapters and three appendices. It develops four original analytical frameworks:
- The Mark Heptad — a taxonomy of seven adversary motivations (financial, espionage, war/defense, facilitation, hacktivism, revenge, nuisance) that maps directly to deterrence strategy
- The IMCM Framework — Ignorance, Mistake, Complacency, Malice — for classifying human-induced vulnerabilities and matching them to specific interventions
- The DIVE Framework — Direction, Intensity, Vulnerability, Exposure — for assessing specific exposure surfaces
- The Multiplicative Security Model — the mathematical basis for defense-in-depth, with implications for how security architecture should actually combine
These original frameworks sit within a broader analytical apparatus drawn from criminology (Cohen and Felson’s Routine Activity Theory, Cornish and Clarke’s Twenty-Five Techniques of Situational Crime Prevention), cognitive science (Kahneman and Tversky on judgment under uncertainty), military theory (Sun Tzu, Clausewitz, contemporary unrestricted warfare doctrine), and systems-safety scholarship (James Reason’s Swiss Cheese Model, Charles Perrow’s normal-accident theory).
The book also examines — and critically engages — the victim-blaming reflex that dominates post-incident analysis, drawing on the foundational criminological literature on victim precipitation and contemporary case studies including Equifax, OPM, Target, and Snowflake.
A note on the Latin title
Scientia Securitatis translates as “the science of security,” and the choice was deliberate. The Latin signals that the book engages security as a serious analytical discipline whose intellectual roots long predate the cybersecurity industry’s tendency to treat its problems as historically unprecedented. The phenomena security examines are ancient; the framework for studying them rigorously has been available since at least the mid-20th century. The book argues that practitioners have, with rare exceptions, declined to use it.
Who this book is for
This book is for the practitioner who has noticed that decades of escalating security investment have not produced proportional security gains, and who wants to understand why. It is for the security executive building defensible programs across multiple domains. The policy professional confronting unrestricted warfare doctrine. The risk and compliance leader who suspects that frameworks alone are not stopping sophisticated adversaries. The graduate student approaching security as an analytical discipline rather than a job category.
It is not a tactical handbook. It is not a configuration guide. It is the analytical apparatus that determines whether tactical choices are well-made — the apparatus the field has been operating without.
Where to get it
Scientia Securitatis: The Science of Security is available now on Amazon in eBook, paperback, and hardcover formats:
If you find the book useful, please consider leaving a review. Self-published analytical nonfiction lives and dies by word-of-mouth among the practitioners it was written for — and a thoughtful Amazon review from a working professional is worth more to other professionals than any amount of marketing.

Autocracy, Anocracy, & Democracy – “Verbal Masterba(bleep!)…” January 25, 2016

Election season in the US is always interesting. Passions run high and people are quick to proclaim their positions on government and politics. Unfortunately, as many will likely agree, election season also gives voice to many who should probably remain silent.
Recently I was taken to task on Facebook and lectured on the concept of governance and democracy by a particularly obtuse and offensive individual. When I attempted to explain that democracy should NOT be considered a strictly binary proposition and that the US was indeed a democracy, his attacks became personal and I was accused of (among other things) “verbal masturbation”. According to this master of the English language: “Most folks like me would call your ideas verbal masturbation. They sound good from the outside but are really kinda stupid”…he actually wrote: “Kinda”…somehow this person drew a line between my comments on democracy and his belief that the federal government would force parents to stand by while their 12 year old daughters got abortions without consent. I am at a loss as to the logic… But…I digress. Back to democracy! (more…)

Smartphones have changed the way we interact with our world. They’ve introduced a new level of convenience, but they’ve also introduced a new potential threat to our privacy. As consumers, we should be informed about the choices that we make on our smartphones and how they might impact us. For example, I upgraded my iPhone to iOS 6 this afternoon. (I know. I’m a little late on that one.) Anyway, when I was done I got two prompts. The first asked if I wanted to enable location services. I said yes, knowing that meant that 1) I could use the “find my phone” app, as well as many other apps that come in handy for a frequent traveler, and; 2) that it meant that Apple would have access to my location data. The next prompt suggested that Apple could improve its products and services if I just allowed my phone to send occasional reports to headquarters. That one I declined. I don’t necessarily want Apple to have access to all of my activities on my smartphone.
Now, I’m not naive enough to believe that my simple selection means that I have safely secured my data and mobile behavior entirely. There are companies that are taking advantage of the fact that privacy laws have not kept pace with technology. We know for example, that there are companies that offer device fingerprinting services for fraud prevention that also happen to sell mobile device behavior analytics to marketers. Consumers don’t have any way of knowing that their behavior is being tracked and they have no way to opt out.
This week, Sen. Franken (D-Minn) and Sen. Blumenthal (D-Conn) introduced a bill designed to protect mobile privacy. The Location Privacy Protection Act of 2011 is meant to protect consumer privacy by informing users of how and with whom their location data is shared. There are four primary requirements of the bill. Distilled to their basics, those requirements are:
1) Gain consumer consent before collecting location data
2) Get consumer consent before sharing that data
3) Assist in understanding and investigating crimes that involve the misuse of location data
and
4) create criminal penalties for those that abuse location services or use so-called “stalking apps.”
While I applaud the move to ensure that mobile users are protected from entities divulging their location without the knowledge or consent of the consumer, I wonder if the law goes far enough in protecting consumer privacy. What about those device fingerprinting activities? Do you think the proposed bill goes far enough? Too far? What would you like to see in terms of mobile privacy protection?

Last week, Democratic leaders made some minor news when they sent a letter to President Obama suggesting that he issue an executive order on Cybersecurity. Their position is that, since Congress seems to be at loggerheads over the issue, the president should take the opportunity to force action by issuing an Executive Order. In fact, Secretary of Homeland Security Janet Napolitano told a congressional committee that just such an order was in its final stages. So what might we see in this forthcoming order?
According to reports, the order will attempt to regulate sixteen “critical” industries. The guidelines will be voluntary, after a fashion. Compliance with the standards may determine eligibility for federal contracts. The White House has not made any secret about its intentions on Cybersecurity. In fact, the White House website lists “Ten Near Term Actions to Support Our Cybersecurity Strategy.” Brevity prevents me from getting into a deep discussion about those actions here, but you can read them and draw your own conclusions.
The questions remain, however – 1) how stringent (read intrusive) will the requirements be?; 2) Will they be relevant to the threats in the landscape?; 3) How will compliance be policed? and 4) How much additional cost are we potentially adding our already stretched budgets?
Another question that merits examination is whether or not the standards will be redundant. Many industries are already straining under the weight of a variety of infosec requirements – whether industry-regulated or government mandated? Will another layer of regulation mean increased efficacy of data protection strategies and mandates or will it be just another layer of red tape?
