Five Cybersecurity Truths That Should Inform the CFO’s Spending

Cyber risks, it seems, are everywhere. Retailers breached. Intellectual property stolen. Data hacked almost on a daily basis. It’s enough to rattle even the most steadfast of chief financial officers – and often it does.

In fact, in our quarterly CFO Signals™ survey, cyber attacks have become a fixture on the list of CFOs’ most worrisome risks, which includes perennial macroeconomic factors, such as economic volatility and overregulation. Four years ago, when the survey first launched, cyber risk was rarely mentioned.

And in our CFO Transition Lab™ sessions, newly named CFOs tell us of their increasing concern for cyber attacks as well.

A company’s probability of a material breach involving 10,000 records or more stands at 22% over the next 24 months

That change in mind-set is directly correlated to both the frequency and the cost of cyber attacks. According to the Ponemon Institute’s “2014 Cost of Breach: Global Analysis” study, the average total cost for a data breach is now US$3.5 million globally, up 15% from last year (and considerably higher – US$5.85 million – for US companies).

In addition, the survey found that a company’s probability of a material breach involving 10,000 records or more stands at 22% over the next 24 months.

Given the costs and the increasingly malicious nature of the attacks, CFOs are understandably focused on identifying potential cyber risks and planning their corporate responses. Moreover, with a large percentage of finance chiefs also overseeing IT, they are equally committed to determining how and where to invest company resources on prevention.

In this article, we will discuss some basic “truths” about cybersecurity and offer guidelines for investing in an enterprise-wide cybersecurity plan.

Sophisticated attackers

For CFOs, getting a handle on cyber risk can be a frustrating process. Part of the problem is that finance chiefs typically don’t have trend information on their companies’ vulnerability.

Plus, with the ubiquitous nature of cyber risk, classic security controls (firewalls, antivirus, Intrusion Detection Systems, Intrusion Prevention Systems, and so on) are increasingly less effective as attackers employ innovative techniques to evade them (see Deloitte LLP video: “Companies like yours”).

Meanwhile, the battlefield keeps expanding. Consider the march to the Cloud. While the potential savings might be attractive, there’s inherent security issues with going to the Cloud, such as “Who has access to my data in the Cloud?” and “Can it be shared with other customers?”

Compounding the problem is the mobile evolution. In addition to standard desktop computers, company-issued laptops, PDAs, cell phones, and mobile phones typically offer a wealth of personal information and multiple access points for cyber thieves.

Those thieves are also patient: no longer focused on “smash and grab,” they are operating below the security radar of victim organizations and maintaining a presence for years.

Reality check

What that means is that companies – and CFOs – are fighting a multi-front, long-term battle where victory is difficult to measure. To have any chance of winning the cyber wars, there are several realities that CFOs should understand:

Your information network will be compromised. Unfortunately, it’s inevitable that you will be attacked. If you operate an information network, you’re not going to get to a point of zero risk. Accept it.

Physical security and cybersecurity are increasingly linked. Typically, the physical security domain and the cybersecurity domain have been viewed separately. But that is no longer the case.

Why? While threats like espionage, intellectual property theft, fraud, counterfeiting, and terrorism may involve cyber breaches, they potentially can begin by physical access.

In a common example, certain administrators may have full control over a system such as payroll, customer data, or billing. 

Armed with that access, those employees or contractors might pay themselves with false invoices, approve loans with special rates – or copy customer credit-card data and employee files containing sensitive information such as Social Security numbers, with the purpose of selling the data, creating identity theft, embezzlement, or other fraud.

Cyber damages go beyond dollars. While the average cost of a data breach may be well documented, the long-term effects on corporate reputation and brand significantly add to the toll.

In particular, breaches of customer data can lead to a breakdown in trust that could inevitably hurt the top line – one reason several payment networks are demanding that retailers move to new payment cards that store information on computer chips rather than on traditional magnetic stripes.

By making a hierarchy of data customized to your company and industry CFOs can also make better decisions on how to prioritize protective controls

Everything can’t be protected equally. Ask yourself, “What and where are the crown jewels in my organization?” In other words, what data is crucial to running the organization, and what databases, if compromised, could put you out of business?

Not every piece of information, after all, is equally important. To a retailer, for example, customer credit-card data and employee Social Security numbers are crucial, as is logistics information related to supply chains.

By making a hierarchy of data customized to your company and industry, however, CFOs can also make better decisions on how to prioritize protective controls and other aspects of cyber spend.

Your walls are probably high enough. Companies continue to invest heavily in the protection side of cybersecurity – more firewalls, more intrusion-detection systems.

But most wall building may be about as high as it needs to be. Given that hackers have likely already infiltrated, companies should focus more on the detection side to increase their vigilance against attacks and on recovery after the fact.

The formula is different for every company, of course. But of the typical IT cyber-risk spend, 30% might be allocated to wall building, 50% to detection, and another 20% to resilience preparation.

Action steps to take

Accepting these “truths” is foundational to instituting an effective enterprise-wide cyber-risk plan. The action steps that can then be taken include the following:

Create a corporate-wide cyber mind-set. There has to be awareness, education, and training throughout the organization to combat cyber risk.

You may have top-notch hardware and software to protect you against cyber intruders, but it might take only one unaware employee opening an attachment with malicious software to shut down your systems. The tone in combating this really does start at the top, with the board, CEO, and the CFO setting the governance and the organizational structure and making sure all employees are aware of their role in preventing cyber attacks.

Ask the right questions, of the right sources. As CFO, your go-to sources about cyber risk are typically the CIO, the chief risk officer, and the chief information security officer.

The following questions can inform the dialogue:

  • How do we identify our critical assets, associated risks, and vulnerabilities?
  • Do we have a well-tested incident response and communication plan?
  • Do we track what information is leaving our organization and where it is going?
  • How do we know who’s really logging into our network, and from where?
  • Can we limit the information we voluntarily make available to a cyber adversary?
  • Do our security controls cover the entire company, including subsidiaries and affiliates? (Most often the answer will be no.)

Adopt a cybersecurity framework. In February, after a year-long private-sector effort, the Framework for Improving Critical Infrastructure Cybersecurity Version 1.0 was released by the National Institute of Standards and Technology.

The framework is intended to provide companies with a set of industry standards for managing cybersecurity risks. Voluntary in nature, it defines how to identify, protect, detect, respond, and recover from cyber threats. The hope is that it will become a baseline leading practice for companies to use in, say, assessing legal exposure to cyber risks.

The framework may impact your organization in several ways, including driving greater involvement by the board in overseeing cybersecurity risk and potentially requiring information-sharing protocols to be established.

Lack of adoption, on the other hand, may lead to additional regulation for “critical infrastructure” sectors.

Designate an “Inspector General.” One leading practice that some companies are employing is to shift the monitoring and investigation of cyber risk to an internal designee, whose role is like that of an Inspector General. That person is then charged with investigating a breach if it occurs and reporting out.

The Inspector General does not own all of security, but can break the language barrier between cyber specialists and management. In some companies, for example, CIOs are charged with maintaining an adequate level of walls, but the monitoring or detection is done by someone in the risk organization who reports up to the CFO.

Get educated. As CFO, you have to be educated on cyber risks and not rely solely on your CIO, CISO, or even the designated Inspector General (if you have one).

That doesn’t mean simply taking an online course or reading one of the hundreds of cybersecurity books now in circulation. It means gaining hands-on exposure to cyber threats through modeling your business risks and then digging into the “what and how” of security.

Test the security plans. Cyber-simulation exercises allow participants to face off as the good guys and bad guys in real time, and offer a way to quickly get up to speed on the risks, identify where the organization’s most important assets are, and pinpoint solutions for prevention.

A measure of security

Companies are under a continuous threat of cyber attack – a threat that cannot be ignored. By understanding these truths and instituting these action steps, CFOs may not gain complete comfort, but they may achieve a comfort level based on the protect-and-detect controls within their risk tolerance.

The very nature of cybersecurity, after all, doesn’t allow for a total solution. But, by instituting an enterprise-wide cyber plan, CFOs may at least achieve some measure of security.
