Recruiting and Retaining Cybersecurity Talent
Thoughts on IoT Vulnerabilities
- The business has a “great idea” that’s highly innovative
- Business leaders discuss the benefits, costs, and risk…usually without security personnel present.
- The business leaders get approval to pursue their idea and select a vendor…again, usually without input from security
- Sometime between proof-of-concept and going into production – and usually due to the fact that approvals of some sort are needed in order to go live – security is notified of the plan and asked to approve
- Security personnel start to (gasp!) ask questions about the security ramifications. They introduce risk concepts not solely related to profit and loss that are relevant to the implementation.
- Business leaders complain to executives that security is “slowing things down” and “disrupting” business
- In the end, one of two things happens: (a) the business implements a “shadow IT” infrastructure to achieve their objectives; or (b) the implementation is modified to account for security
- Regardless of the decision in (7), the desired results which drove the innovative idea aren’t fully recognized or realized. In the case of Shadow IT, this gap is usually because the rogue implementation cannot be fully supported and/or cannot be scaled appropriately. In the case of a modified implementation, the modifications usually end up limiting some of the originally planned functionality
- In the end, the business needs to take a different path to achieve its revenue objectives…resulting in further ideation and a brand new “great idea.”

Cyberwar Revisited
Over the past couple of weeks, I've had occasion to reflect upon the concept of “cyber warfare.” On one occasion I found myself disagreeing with a member of the local cyber community when he said, “make no mistake we are at war." On another (more interesting) occasion I was speaking with a couple of law students who were discussing the possibility of redefining what “war” means in order to “deal with the new realm of cyberspace.”
The term war brings with it a certain amount of gravitas but with it also comes a plethora of baggage. The only thing more dangerous, though, than misrepresenting something as “war” is to invent new terms for things that are already well defined – similar to our reinvention of “torture” as “enhanced interrogation techniques.” (My father was water boarded as a POW in Korea; in his words, “torture” is the only accurate term to describe this practice).
Rather than redefining “warfare,” mayhap it is time to use the existing lexicon to see where illegal acts in cyberspace accurately belong. From a legal perspective, most activities have five basic components:
· A subject or actor…
· Takes an action…
· Against a recipient or object…
· With some intention…
· Achieving some result.
It is the combination of all five of these elements that helps differentiate actions within any legal framework. Intending to run down someone and kill them with your car, for example, is premediated murder (assuming you succeed) but might only be involuntary manslaughter if no intent was there.
When applied to nation-states, this legal calculus gets particularly interesting. We must assume that all nation-states will act with the intention of furthering their own existence and/or prominence…which, by definition means the weakening of some of the other nation-states around them. If this is indeed the case, then the question that arises is whether the actions – ANY actions – by one nation-state against another should be considered an act of war. Should the signing of a diplomatic treaty between two nations which limits a 3rd nation’s access to a desired resource/capability constitute an act of war against that 3rd nation? Let’s hope not, as this would call into question every nuclear proliferation treaty currently in existence. If a nation state uses its resources to infiltrate and sabotage part of a nation’s infrastructure-building efforts in order to maintain or achieve a certain advantage (either geopolitically or during a future kinetic war), is that act itself an act of war? Again, if it is then our participation in the Stuxnet attack against Iran in 2010 is tantamount to a declaration of war versus an act of espionage.
My point is this: while the attack surface is vast and the weapons are different – and can be frightful – leaping to terms such as “warfare” and/or redefining acts of espionage as “war” are inappropriate solutions to addressing acts of malfeasance in cyberspance. Make no mistake: I do believe that certain nation-state actors are indeed trying to limit if not destroy US influences and interests in the world…just as I believe that we have similar objectives when it comes to some of our more powerful (and more contentious) world neighbors. Weighting this actions, though, with the baggage of “war” carries with it the spectre of unintended consequences…
…similar to those we might experience during the next kinetic war when a US soldier is tortured and our enemy responds that they were only using “enhanced interrogation techniques.”
My two cents…

Ending the Hiatus

My Christmas Wish List
- For the team of consummate security professionals that I work with now and have worked with over the years, I wish for them at least one week's worth of uninterrupted sleep. These are some of the finest sheepdogs (a la the Dave Grossman definition) that I've had the privilege of serving with; they deserve some worry-free rest from the fight, if only for a moment.
- For the spouses of every security professional that I know (including mine), I wish for them a refilling/replenishing of that seemingly endless font of patience and understanding that they continuously display. It is said that the wives of Spartans are the secret pillars which hold up the world; the significant others of security professionals prove this day-in and day-out as meals are interrupted, special dates are missed, and date nights are cancelled in our quest to keep the dragons at bay in the organizations that we are charged with protecting. May they never lose their love of -- or patience with -- us as we continue to stand in the gap.
- For my son and those of his generation, I wish for a vigorous, pointed, and decidedly uncomfortable discussion on the true concept and meaning of privacy in 2016. While accepting that the definition (and expectation) of that term is evolving, the impacts of big data, data analytics, and the internet of things on the "Minority Report Generation" are only beginning to be felt and understood. If nothing else, I believe an acceleration and increase in the discourse is long overdue.

Speaking the "Language of Security"
Recently, I've come across a spate of articles discussing the need for security professionals to "speak the language of the business." This phrase has been used often to describe the underlying reason that CSOs and CISOs are not considered strategic partners to the business leadership (Taylor Armerding's recent article in CSO summarizes the situation rather nicely.). Sure, we can all do better at dumping the professional technical jargon (and this has gotten much better over the past decade); but even as we summarize risk tradeoffs in plain English, we Warriors of the Light are still met with this biting (and trite) criticism regarding our inability to communicate with out most important constituent. When I've asked senior business professionals what "the language of the business" means to them, I've gotten inconsistent, nebulous answers. The best answer I received regarding this topic came from a former CEO who came up through the finance ranks. "The answer is dollars," he said to me. "Until you can tell me with absolute certainty what not patching that system will cost me in dollars, or what the absolute risk in dollars will be of not giving you a new tool or another body, I will always question the truth of your calculus." This calculus makes us slightly different from our IT brethren, who can link their costs more directly to revenue via availability and/or new business.
A hard truth, to be sure. Our profession will continue to struggle against this perspective. This truth will become harder still as the scrutiny of senior leaders and even the Board of Directors increases around security issues due to external regulatory and consumer pressures. Yes, we security professionals still own the bulk of the communication challenge…
…but we do not own it alone.
While I applaud, support, and participate in the efforts of the security community to bridge the communications gap -- and let's be clear, it is our gap to bridge -- it's time to address the other side of this equation: the business itself. Communication, by definition, is two-way. While it's incumbent upon me to learn the language of the environment in which I operate, it is equally important for our business brethren to understand and appreciate some of the equally hard truths that exist within security's operating space.
Here are some hard truths that security professionals would like business leaders to understand:
- I Don't Want to Be Your Top Priority. I recently heard a former storied CEO and current board member of several prominent tech companies say, "I want to know enough about security to know that we are okay, so I can go on to the next marketing problem." Frankly, I feel this attitude and approach is healthy. He hired a CSO to take security off his mind. If that CSO does his job correctly, the CEO's concerns will fade considerably. There are, however, some upfront costs to that approach. The CEO and CSO need to work together to decide how to depict data in a manner which resonates with his concerns. My tools and processes can measure dozens of data sets, but what are truly the best way to show the amount of work it's going to take to defend the network? Or the daily normalcy of attacks that occur (and our success rates against them)? As your security professional, I will work hard to determine the correct metrics to depict an appropriate understanding of the landscape, as well as a holistic picture of our security posture…but this will take some trial-and-error and some back-and-forth between us. Be willing to make the time for that collaborative discussion, as I am truly terrible at mind reading Just ask my wife.
- While I Don't Need You To Agree With Me, I Do Need You to Listen To What I Have To Say. Contrary to anecdotal opinion, I'm not an alarmist. The sky is not falling, nor are the evil hacker hordes storming the gates RIGHT NOW. If I express a concern about a business practice or operational decision, don't dismiss me as a paranoid zealot who sees disaster around every corner. Just like business leaders, security professionals hone their craft over the course of many years. Our understanding of risk issues is as valid as a business leader's understanding of market opportunities. Give us the courtesy of your focus when we express a concern, even when we can't necessarily present data analytics. Be aware that sometimes empirical data only becomes clear in the aftermath of an event, versus being a predictive indicator.
- Compliance is Not the Same Thing as Security. Too often businesses hire security professionals either (a) in the wake of a breach; (b) to stay ahead of regulatory demands; or (c) to appear 'focused' on security challenges due to external pressures. Nothing wrong with these incentives in the slightest, but the mindset of the business in these situations tends to be focused on staying ahead of regulatory/compliance issues versus addressing security needs. Actions which address truly securing the environment but which aren't explicitly stated as a regulatory requirement are seen as excessive or needless. We still run up against this quite a bit in companies seeking to meet PCI-DSS requirements; many business clearly see the need for a control applied against their credit card data, yet struggle to see the need for similar controls against the petabytes of non-anonymized personal data within their environments. Businesses should be honest with themselves and transparent with their security professionals: if what you're looking for is just compliance, tell us. It'll keep us from banging our heads against the wall as we attempt to bring secure solutions to your enterprise.
- Stop Asking Us "Are We Secure?" The security professional defines "security" as freedom from risk. No matter how good s/he may be, as long as its doors are open for business a company will never achieve a zero-risk state; stop expecting me to tell you that you will. This also applies to operational objectives such as "never being breached" or "zero operational impacts due to security events;" even if you gave me every dollar I requested in my budget, I could never guarantee you such absolute success. Now, asking me if our controls are up and running or how our controls/performance compares to others in our business vertical is fair and reasonable (though the latter may be hard to determine due to a lack of information sharing about security issues).
- Let's Make Tradeoffs Together. The security professional's job is rooted in the principles of risk management. This means making hard choices regarding risk versus return. While we're comfortable with this, some circumstances do and will require additional resources in order to keep the risk at its current level. The business, not the security professional, makes the ultimate decision either to (a) reallocate resources, or (b) accept the risk. This is an important point to emphasize, because security professionals are facing multiple challenges in this area.
At the end of the day, the function of a business is to make money. Business leaders can be reluctant to acknowledge an increase in security risk, since risk mitigation may be costly and blame can be the market's first reaction in the event of an incident. Security professionals do understand the risk tradeoffs, and accept them as part of growing a profitable business. We need open, honest dialogue with you regarding risk tradeoffs.
- I Will Support & Defend the Business, Regardless of the Decision You Make. Once I've been heard and we've discussed tradeoffs, I will support your decision and execute it to the best of my ability. Your decision to accept additional risk does not give me a free pass to let bad things happen in the environment. A security professional will always fight to keep the evil hacker hordes from storming the gates, regardless of the risk decisions made. Period.
While the bulk of the communication burden rests with the security professional, I believe business leaders also have a responsibility to come to the table ready for an honest, open dialogue. Not wishing to burden the company with costs not associated with direct revenue benefit is not a sufficient reason to avoid the expertise and knowledge your CSO brings to any discussion. Give him a listen - he might just surprise you.
