Cybersecurity: Five essential truths
Given the costs and the increasingly malicious nature of cyber attacks, Chief Financial Officers (CFOs) are understandably focused on identifying potential cyber risks and planning their corporate responses.
Cyber risks, it seems, are everywhere. Retailers breached. Intellectual property
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.1 In fact, four years ago when the survey first launched,
That change in
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 issue of CFO Insights, we will discuss some basic “truths” about
Fighting a moving—and evolving—target
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 [IDS], Intrusion Prevention Systems [IPS], and so on) are increasingly less effective as attackers employ innovative techniques to evade them (see Deloitte LLP video: “Companies like yours”4).
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.
What that means is that companies—and CFOs—are fighting a multifront, long-term battle where victory is difficult to measure. To have any chance of winning the cyber wars, however, 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
cybersecurityare increasingly linked. Typically, the physical security domain and the cybersecuritydomain have been viewed separately. But that is no longer the case. Why? While threats like espionage, intellectual property theft, fraud, counterfeiting, and terrorismmay 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. And 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 stripes5. In addition, many companies are now considering cyber insurance to limit excessive damages.
- 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 percent might be allocated to wall building, 50 percent to detection and another 20 percent to resilience preparation.
Tenets of effective cyber-risk programs
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
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 (CRO), and the chief information security officer (CISO). The following questions can inform the
- 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 yearlong private-sector effort, the Framework for Improving Critical Infrastructure Cybersecurity Version 1.0 was released by the National Institute of Standards and Technology6. A specific deliverable from the “Executive Order—Improving Critical Infrastructure Cybersecurity” that President Obama announced in his 2013 State of the Union address, the framework is intended to provide companies with a set of industry standards for managing
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 CRO 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. That doesn’t mean simply taking an online course or reading one of the hundreds of
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.
Gaining a comfort level
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
There are steps you can take to reduce the threat of a cyber attack. In fact, according to the Ponemon Institute’s “2014 Cost of Data Breach Study: Global Analysis” study, having a strong security posture, incident response plan, and chief information security officer appointment reduced the cost of a data breach by $14.14, $12.77, and $6.59, per record, respectively.7 In addition, the following actions can guide CFOs in instituting an enterprise-wide cyber-security plan:
- Evaluate the existing
cyber-incidentresponse plan. Focus on the controls for the “crown jewels” and what you would do in the event of an incident. The team responsible for this should include senior management from the lines of businesses and administrative functions.
- Identify finance’s role in cybersecurity. Work with your CIO and the business leaders to see how finance can help create the necessary culture of security and privacy. Organizations can enhance their security stance by valuing cybersecurity and the protection of privacy and viewing. Remember: “Security begins with me.”
- Require regular reports on security risks. These reports should be from senior management and detail privacy and security risks, based not on project status but on specific risk indicators.
- Review the
cybersecuritybudget. Many times, security budgets take a backseat to other IT or business priorities, resulting in companies being unprepared to deal with risks and attacks. An annual review of cybersecurity budgets is recommended.
- Reevaluate cyber insurance. Also on an annual basis, revisit the use and need of cyber insurance.
