Physical and Logical Security: Joining Forces to Manage your Enterprise Security Risk

Just a decade ago, as security professionals, we could talk reasonably about physical security and logical security requiring different approaches. Five years ago, we might have found ourselves having conversations about the blurring lines between the two types of security discipline, and could have easily pointed to aspects of both physical and logical security that crossed over each other.

Today? In organizations that have embraced even the least cutting-edge aspects of operational and information technological advances (consumer IoT, industrial IoT, cloud hosted services, etc.), we can no longer rationally discuss a strictly “physical” or “logical” approach to managing security risks to the enterprise.

Quite simply, in a world where:

  • Every camera and door lock in a facility has an individual IP address
  • All security investigations must happen in the real and virtual worlds at the same time
  • Even the most visibly “physical” of protective measures – security officers – are networked via trackers and devices to provide instant information and communication
    … there are few, if any, areas left that do not require attention to a holistic and comprehensive view of all security disciplines at once.

What does this mean for the personnel and management teams that are tasked with providing security in this borderless environment? How do we, as practitioners who may have long histories in a single discipline, protect the organization in a security environment where the risks and mitigation tactics have converged, regardless of whether our organizational structures have evolved to match them?

The answer: Enterprise Security Risk Management (ESRM).

ESRM is a risk management model that allows all functional areas tasked with mitigating security risk to operate under a converged philosophy and approach to more efficiently and effectively mitigate security risk across the enterprise, regardless of the physical or logical nature of the asset, or the vector of the potential threat.

Recognizing the Role
ESRM allows security personnel to work together to effectively protect the enterprise from a broad spectrum of security risks by first recognizing that it is the role of the security organization, at root, to manage security risk in conjunction with the business, and to protect assets from harm in line with business tolerance.

The tasks we perform to mitigate risks might be different, but the process of identifying the assets to be protected, recognizing and prioritizing the risks to those assets, and then mitigating the assets to within acceptable levels of business tolerance, are the same. Take a look at the table below, excerpted from the forthcoming book, Enterprise Security Risk Management: Concepts and Applications (Allen & Loyear, 2017). It shows a quick side-by-side of the kinds of tasks that security groups do, and how they are essentially mitigation responses to the same security risks.

The overarching risks cannot be effectively mitigated by only a single tactical function. Working together, under a common risk management framework, all security personnel can more effectively protect the enterprise environment against security risk.

The Benefits of ESRM and Cross-Functional Risk Management Collaboration
Managing all security risks in partnership and under a common ESRM approach can bring the enterprise significant gains in efficiency and effectiveness, even with multiple groups participating in the security partnership. A few to note include:

  • Unified security awareness messaging
    • A partnership approach under an ESRM philosophy allows for the creation of a single, unified, security message that include all facets of security awareness.
  • Single security point-of-contact
    • When all security teams operate under the risk-management approach with the same defined processes, any security incident can be reported to a single point in the company and escalated and directed as needed to the appropriate response team.
  • Operational efficiency
    • Employees with different skill sets can more easily collaborate on incident response processes.
    • Information sharing enables cross-department cooperation during security investigations that require both physical and logical forensics.
    • Streamlined processes save hours and money, allowing diverse security risks to be managed by a single process.
    • Consolidated metrics reporting to business management save time and effort.
  • Optimized risk profile
    • All security risks are identified and managed in an overarching program, making the risk identification and mitigation process more robust and decreasing the potential of overlooked risk.

How Do We Get There?
So, how do we get to the point of converging under a common philosophy, regardless of reporting lines and department structures?

All leaders in the organization with any security responsibilities can align with a risk-management approach by asking themselves:

  • Does my team have clear risk management goals aligned with business risk tolerance?
  • Does my team work with other department stakeholders in the risk decision-making process?
  • Do the members of my team work together with other security teams in situations that cross boundaries of scope?
  • Am I communicating to all areas of the business that my role, and the role of all other security teams, is to manage security risks holistically?

When all the security functions in the enterprise choose to embrace a risk management – ESRM – approach, the outcome is that:

  • All security teams follow a formal and consistent process for security risk decision-making.
  • All security teams follow the same incident response approach, including postmortem investigations and root cause analysis to continually improve the security risk situation of the enterprise.
  • All security teams work in partnership with one another, ensuring open communications and collaboration across department lines.
  • All security teams have the transparency, independence, authority and scope needed to do their work in the right way.
  • All security risks, no matter which team mitigates the risks, are considered part of the holistic security risk management program.
  • All security teams, no matter who they report to, understand that security risk management is everyone’s role.

IoT Cybersecurity Act of 2017: A Necessary But Insufficient Approach

The Mirai botnet attack on the DYN network in October 2016 highlighted to many policymakers the potential problems associated with IoT devices. The compromise and concerted use of thousands of webcams and DVRs to disrupt key Internet services focused attention on the poor implementation of security controls on millions of devices newly connected to the Internet.

The introduction of the IoT Cybersecurity Improvement Act of 2017 by a bipartisan group of US senators seeks to address the inherent threat IoT devices pose to federal government services. This bill builds on recent efforts, including the Trump administration’s new executive order on cyber security for federal networks and critical infrastructure.

The IoT Cybersecurity Improvement Act would require the Office of Management and Budget Director to confer with various cabinet and agency officials to define implementation guidance to ensure contracts that enable IoT installation in federal systems meet standards that allow for regular identification and patching of vulnerabilities found in deployed IoT devices across the federal government. The central concept of the bill is the requirement for contractors and agency heads to own the evolving security footprint of IoT devices deployed in their network. This approach is consistent with the Trump administration’s guidance for agency heads to be held responsible for the protection of their networks and critical systems and to include these devices as part of an overall assessment of risk.

While the bill requires contractors to assess deployed “internet connected devices” against vulnerability databases and recommend patching strategies, it does allow agency heads to apply for waivers in cases where devices with “severely limited functionality,” defined as Internet-connected devices with limited data processing and software functionality, can be exempted from the requirement if the executive agency deems it “economically impractical.”

For example, if an agency has deployed 10,000 smart lightbulbs and a vulnerability is found, the head of the organization would be able to request a waiver noting that those lightbulbs have limited functionality and would represent an “undue burden” to replace them with newer models (or push out a patch). It is reasonable for the government to carve out this exception. However, it does raise a fundamental issue. If most IoT devices, including small sensors, lightbulbs, etc., are individually cheap by design (e.g., to be competitively viable as compared to traditional devices), does the introduction of those devices pose an unacceptable risk to the federal agency? Or, in other words, is the agency willing to allow devices that could be used as a relay in a cyber campaign because the devices have “severely limited functionality”?

The bill addresses this problem through the requirement of a risk assessment. In this case, the bill attempts to leverage the current requirement for agencies to develop comprehensive risk frameworks as laid out in the May 11, 2017 US Cybersecurity Executive Order. Those requirements ensure agencies follow the NIST Cybersecurity Framework, which provides organizations with a set of best practices to identify and reduce their cybersecurity risk. This makes sense, yet neither the bill nor the NIST framework provide methodologies for conducting the actual risk assessment. Instead, agencies are left to design and implement their own approaches, which is useful but ultimately problematic, as an inconsistent set of definitions and criteria can be applied.

If IoT devices are structurally incentivized to not integrate robust security controls, and agencies can apply for exemptions to found vulnerabilities, and our application of risk assessment is immature to not fully grasp how those devices can be leveraged by hackers, how can we embrace evolving technology while at the same time protecting the most critical services provided by federal agencies?

The IoT Cybersecurity Improvement Act of 2017 would be a good piece of legislation, as it serves to move the ball forward in highlighting an area of weakness in federal network security. However, the inconsistent and immature processes by which we assess risk to our core services undermines its effectiveness.

What Does the Future of Financial Cyber Security Look Like?

Today, we trust banks and other financial institutions to safely handle our money and the bulk of our monetary transactions. Successful breaches are somewhat rare thanks to technologies like multi-factor authentication and heavy investment in cyber security, but hackers are always improving their techniques, and tech is always changing. This leads to an ongoing cycle of improvement on both sides: financial institutions keep building better defenses, and hackers keep trying to overcome those advancements.

So, could the financial industry eventually get ahead of the cybercriminals? What does the future hold for financial cyber security?

Consumer trust
Financial institutions’ most important job is building and maintaining consumer trust. Without that, people won’t be willing to part with their money, and the entire system could collapse. That’s why financial companies are working hard to stay ahead of the curve, to inform their customers proactively about prospective threats, explain what they’re doing to stop them, and of course, give them the proof that what they’re doing actually works. Third parties will always be around to rate banks and lending institutions for the quality of their offers, and security will only grow in importance as a factor in the future.

New threats
These are some of the most important threats we need to prepare for:

  • Botnet attacks. The concept of a botnet is relatively simple; a hacker uses a program to gain access to multiple independent devices, usually connected in a peer-to-peer web-like network, and then coordinate those devices to execute an attack. This could come in the form of a distributed denial of service (DDoS) attack, or to steal data, which can then be used to compromise financial accounts.
  • Self-mutating viruses. Standard computer viruses already have the potential to infect a computer, enabling the virus creator to steal information from the victim’s computer or use it as part of a botnet in the future. However, antivirus software often catches and eliminates these threats based on recognized patterns. Self-mutating viruses go a step further; they have the capacity to evolve, sometimes in response to direct threats, making them notoriously difficult to detect and prevent. Fortunately, these are in the early stages of development, and haven’t had much of an impact as a cyber threat thus far.
  • Biohacking. Biohacking refers to a number of different possible actions, all of which focus on identifying important people and gaining access to the biological features that make them unique. As biometrics start to become more heavily integrated, biohacking will grow in both importance and prominence, giving hackers a way to obtain fingerprints or other forms of personal information to gain access to systems.
  • BYOD manipulation. Thanks to the rise of mobile devices, many businesses have now adopted a bring-your-own-device (BYOD) policy, allowing and sometimes mandating that individual users bring their personal devices to the centralized workplace. For cyber criminals, this represents a wealth of opportunities; all it takes is one breached device on a shared network to bring the entire system down.

New technologies
These are some of the ways financial institutions are protecting themselves:

  • Biometrics. Biometrics are a branch of security standards that rely on personal information, such as fingerprints, speech patterns, or even the shape of your ears, to authenticate identity. There are still a number of kinks to work out – such as how biometrics change with growth or significant life events – but if perfected, it could make it nearly impossible for thieves to replicate this information on their own.
  • Quantum cryptography. Typical encryptions use a “key,” which is usually randomly generated, to encode information that can only be decoded by authorized devices and programs, at least in theory. Dedicated hackers could uncover the key and use it to translate messages, with enough effort. However, quantum cryptography takes encryption to the next level, relying on the wave function of elementary particles and quantum physics to encode information in a way that is basically unhackable. The technology isn’t foolproof yet, but someday, it could encrypt information with absolute certainty.
  • Blockchain. Blockchain, the technology used to power the crypto-currency Bitcoin, is already starting to be used in the financial industry. It relies on a peer-reviewed open ledger to record and remember transactions, making it nearly impossible to record fraudulent transactions or “steal” from other participants in the chain. It’s a technology still in its infancy, but it has massive disruptive potential.

It’s hard to chart an exact course for the development of technology, as cybercriminals are always looking for surprising new angles, developers are working on projects in secret, and all it takes is one new revelation to force changes on both sides. Still, the world of financial cyber security will be interesting to watch in the coming years.

Will Blockchain Disrupt the Lives of Governance and Assurance Professionals?

 

The blockchain’s distributed ledger paradigm is serving as the supporting foundation to some forms of digital transformation, including the utilization of cryptographic virtual currencies (VCs) such as Bitcoin. These virtual currencies are actively utilized around the globe, both within and outside the circuits of formal economies of countries, with important financial implications including increased economic disintermediation, financial inclusion and extended digital pseudo-ecosystems that combine people, business entities, and a new generation of smart connected components.

Not only is the whole fintech industry becoming substantially disrupted by the paradigm due to the ability to move money in a decentralized and secure peer-to-peer model, but virtually all other industries are prone to substitute often bureaucratic procedures for more automated and smarter business practices.

During recent years, global organizations including the United Nations system, Multilateral Development Banks (MDB), International Financial Institutions (IFI), and the World Economic Forum, were actively engaged in their respective roles trying to commensurate the impact of this paradigm in the societies and economies of the world.

The World Economic Forum, through its intellectual debate about the Fourth Industrial/Digital Revolution, as well as one of its Global Future Councils focused on the “Future of Blockchain,” has been vocal and active on the topic, stating that “blockchain is more than just moving money. It has the potential to transform our lives, and to make the world a more efficient, frictionless place. The number of people around the world living in either broken systems or entirely corrupt systems is staggering. If done right, blockchain could positively reform entire systems.”

In January 2016, the International Monetary Fund released a first-of-its kind professional paper called “Virtual Currencies and Beyond: Initial Considerations.” This so-called staff discussion note gave a serious consideration to how new technologies are driving transformational changes in the global economy, including the emerging utilization of virtual currencies created as private sector systems that, in many cases, facilitate peer-to-peer exchange, bypassing traditional central clearinghouses. The paper also notes that “VCs offer many potential benefits, including greater speed and efficiency in making payments and transfers—particularly across borders––and ultimately promoting financial inclusion. At the same time, VCs pose considerable risks as potential vehicles for money laundering, terrorist financing, tax evasion and fraud.”

In a separate article, the IMF explores the topic of how “The Internet of Trust” is transforming the financial sector. Per its proponents, Bitcoin’s blockchain technology can be used to transform the financial sector fundamentally, for example by reducing the settlement time for securities transactions. With faster settlement, less money needs to be set aside to cover credit and settlement risks—just as collateral is not needed for a cash transaction.

The Inter-American Development Bank (IADB), the main regional development institution for Latin American and Caribbean countries, in March 2017 released the discussion paper “Digital Finance: New Times, New Challenges, New Opportunities,” explaining the financial implications of distributed ledger technologies applied in the region and around the World. The paper explains that “there is growing consensus in the financial services industry that distributed ledger technology (DLT), also known as blockchain, might just be the answer to the need of more efficient management of collateral [risks], resulting in more firms accessing credit, as well as … freeing up intermediaries’ capital for lending, and potential effects on SMEs’ direct and indirect access to multiple ways of credit.”

Now, coming back to the question of what implications and motivations this new paradigm may have in our professional life, I believe that a new generation of the IT governance, oversight and assurance professionals are called to play an elevated role in future ecosystems, economies and societies.

Similar to other emerging topics such as the advanced application of artificial intelligence (AI), big data, cloud computing, and Internet of Things (IoT), this must occur only by providing an unprecedented new level of verification and trust required by the stakeholders to sustain a paradigm that intends to be intrinsically resilient and secure by keeping distributed copies of the thematic ledger supported worldwide, using cryptographic proofs of data integrity and providing tamper-proof ledger entries.

Extraordinary challenges and opportunities are ahead for the millennials’ generation of assurance professionals, when called to provide both holistic and transactional assurance on increasingly complex digital ecosystems that involve people, processes, systems, as well as connected physical entities.

But the level of disruption to the assurance profession may not stop there. As another report, “Here’s Why Robots could be the Future of Finance” from the World Economic Forum pointed, the traditional tasks of human audit work are also highly subject to substitution by artificial intelligence interventions. Meanwhile, some audit tasks may be better assisted by this advanced application of technology. We, the auditors, will face the challenge of providing assurance to our stakeholders that these algorithms are effectively well designed, implemented, deployed and operating as expected.

In our profession, traditional auditing will remain necessary in many parts of the globe and in many traditional businesses environment for a while. However, and not less importantly, a new generation of millennial auditors will need to raise the bar by providing increasingly complex assurance services in more agile business environments and in support of upcoming digital transformations. A different professional audit mindset and additional expertise will be required to satisfy the expectations of stakeholders and business owners in this new world.

Increased Cyber Awareness Must Lead to Equivalent Action

Recent and widely publicized cyber attacks must be the impetus for a renewed and more concerted and coordinated global commitment to strengthen cyber security capabilities.

In May, the WannaCry ransomware attacks struck, underscoring the potentially disastrous consequences for health care facilities and their patients when medical records and medical devices are compromised. June brought yet another major attack in Petya, originally characterized as another widespread ransomware attack, but later revealed to draw upon a form of malware that does not steal data but, in fact, destroys it.

These types of attacks, and those that will follow, accentuate the increasing concerns about the continued escalation of the global cyber security crisis. It’s no longer just about stealing money and data, but one that’s now placing human lives at risk. While health care has been a primary target this time around, more threats loom on the potential for breaches or compromised access to industrial control systems that could result in penetration of critical infrastructure systems such as electric utilities, oil and gas facilities, or nuclear energy plants. This shines a spotlight on the need for a unified global response now.

Amidst the challenges of the current threat landscape, there are promising signs that an increasing number of enterprise leaders and boards of directors are making the defense of their organization against ransomware and other cyber threats a top priority. ISACA’s State of Cyber Security 2017 research showed the percentage of organizations with Chief Information Security Officers (CISOs) is up to 65 percent, a 15-point rise over the year before. And in a micro-poll of the ISACA professional community in the immediate aftermath of the Petya incident, half of respondents indicated they took action after WannaCry to bolster their defenses – in case something like Petya showed up.

Additionally, half of the post-Petya poll respondents indicated their organizations provide ransomware awareness training to their staff, and more than half of organizations are applying software patches within the first week that they are available. That’s a good start. Promoting cyber security awareness and adhering to basic cyber security fundamentals needs to be as common in the global digital economy as seatbelts are in cars. We have a long way to go to make this the reality.

While the past several months have created an aura of inevitability around major attacks, more than 4 in 5 respondents to our micro-poll indicate they expect ransomware attacks will be even more prevalent in the second half of 2017.We cannot accept this level of havoc as a ‘new normal.’ Putting in place a viable incident response plan is critical, but what’s worthy of further investment is protection before an attack happens. Every organization should proactively employ cyber security awareness for all staff, performance-based cyber security skills training, timely hardware and software updates, and the hiring of the most highly skilled staff to ensure preparedness for the next attack, ransomware or otherwise. Start with an assumption that your organization will be the next target of a cyber attack.

Governments need to exhibit bold leadership and do more, too. This includes a commitment from G20 nations to expand cyber security research and training, and standardize some of the measures that individual nations are putting in place. G20 nations also should consider providing cyber security resources and support to nations that are not equipped to invest in themselves, as the connectivity of the global digital economy means all of us are in this together. This can help amplify the reach of encouraging efforts that are unfolding at national levels, such as the UK’s National Cyber Security Strategy and the recent executive order on cyber security in the US. Expanding public-private cyber security partnerships, while leveraging the resources of industry associations and academia, also should be part of the solution.

As a global community, we remain vulnerable to the cyber threats that already are here today, as well as the ones that will surface tomorrow. We cannot fall victim to cyber attack ‘fatigue’; attacks like the WannaCrys and Petyas cannot become “business as usual.” Cyber security is everybody’s business. Cyber security is more than pickpocketing; it’s a matter of public safety. Awareness must translate into resolve, not resignation. Only then will we make even greater leaps toward a more safe and secure future.
