On March 2, the Biden Administration announced a new National Cybersecurity Strategy. The need for a strategic change should not come as a surprise — Interos’ 2022 Resilience survey of 1,500 procurement and cybersecurity leaders revealed supply chain disruptions from cyber incidents alone cost enterprises $37M annually. Estimates of the global annual cost of cybercrime exceed ten trillion dollars.
Interos is closely monitoring the rising costs of cyber disruption and the continuously changing state of play, among other factors. We’ve refined and updated our cyber risk factor, one of the six factors within the Interos i-ScoreTM, in light of these and other trends shaping cybersecurity. The enhancements include a new cyber behavior model to detect potentially harmful cyber activity regardless of public disclosure, along with commercial cyber ratings, vulnerability information (CVEs), threat assessment (Mitre ATT&CK®), cyber events, regulatory compliance, and operating country regulations and risks into a single score.
You can read about those details in our press release. This blog will focus on those strategic factors driving these changes and the challenges in developing a solution that delivers cybersecurity insights to non-experts, all within the backdrop of the generational shift underway in the international system.
Trends Driving the New Model
To address the growth in scope and scale of cyberattacks (and their ripple effect across the supply chain) the Biden administration’s new National Cybersecurity Strategy is putting more responsibility on vendors and service providers. This is part of a larger trend prompting organizations to prioritize long-term collective investment in cyber resilience – and is reflective of Interos’ collective resilience approach to cyber.
Cyber leaders are also increasingly acknowledging the human element and assessing those risks through a socio-technical lens. This has led to both a focus on user interactions as well as the growth in new compliance frameworks and regulations. That’s why the enhanced Interos cyber risk factor accounts for compliance with CSF V1.1, NIST SP 800-53, PCI DSS V3.2.1 and other standards, as well as the global expansion of data privacy and cybersecurity regulations.
To that end, an organization’s geographic location plays a crucial role in both compliance as well as data risk levels. This variation stems from differing levels of data sovereignty which depend on the localized cyber and privacy environment. Risks surrounding the concentration of the physical infrastructure underpinning the internet also pose a significant challenge, as seen in the case of Russia’s cyberattack on ViaSat’s services in Ukraine or the disconnection of undersea cables which happened in Scotland and France.
The adoption of collective resilience (creating shared supply chain and operational strength) is accompanying our broader understanding of the range of cyber risks, which is why collaboration is prioritized in national and international cyber strategies. As Alejandro Mayorkas, the Secretary of Homeland Security, noted, “We have to drive the entire ecosystem to be more cyber vigilant.”
Developing Interos’ Enhanced Cyber Model
Tackling Key Challenges in the Cybersecurity Landscape
Development of this new model address two core challenges:
- Aggregating Data into Intuitive Formats: The difficulty of integrating disparate data sets in a timely manner and presenting them in an intuitive, explorable format. We recognize that many cybersecurity tools are designed for information security professionals, making them inaccessible to others involved in risk management.
- Understanding Behavior: The importance of understanding both threat actors’ and defenders’ behaviors and integrating that knowledge to identify the most relevant risks.
Cyber has an interesting data problem in that there is a data deluge and a data desert at the same time – meaning there is so much data, but it’s not always the relevant data. The Interos model addresses the above challenges by focusing on integrating and presenting the range of these trends (over individual data points) to capture the core areas of vulnerabilities, threats, compliance, and adverse cyber events. Through this holistic approach we can provide a comprehensive view of cybersecurity risks across the entire supply chain ecosystem, from vendors and service providers to critical infrastructure and sensitive data.
We also utilized the extensive community work and expertise from federal organizations like NIST CVE and MITRE’s ATT&CK framework while accounting for both opportunistic and targeted threats by identifying industries/groups most susceptible to targeting, and vulnerabilities most likely to be exploited. Our approach also focused on quantifying data risks across locations by merging different data types to capture the diverse data sovereignty and global risk environments — a project we presented at Black Hat cybersecurity conference a few years ago.
Implications and Value: Uncovering Hidden Risks and Enabling Proactive Measures
The implications of this new model are vast. It highlights areas of risk that often are not brought together, allowing users to take action to decrease cyber risk. This may include reaching out to critical suppliers that may be at risk and coordinating a plan to elevate their defensive posture, or identifying those key parts of their supply chain located in areas where the data may be more at risk due to an adverse regulatory environment.
The Interos model surfaces a range of cyber risks, while contextualizing those risks within a broader supply chain risk framework. For instance, users can identify who might be at high cyber risk as well as high financial risk, since these suppliers may not have the resources to grow their defensive posture or could be extremely vulnerable to insolvency if attacked given the cost of breaches.
Personal Observations: Expanding Access to Cyber Risk and Addressing Global Challenges
Two particular aspects of this project are especially important to me, in terms of their ability to address broader systemic challenges across the industry that have significant implications for the future :
- Addressing the cyber industry’s gatekeeper problem, which restricts risk assessment access to those with information security technical expertise. Interos’ updated model marks a significant stride towards broadening access to cyber risk assessment outside of an enterprise’s Security Operations Center.
- Further integrating supply chain risk and cyber risk, particularly in the context of a re-globalized world economy, technological bifurcation, and the geopolitical fracturing of the internet. This integration is essential for fostering cyber vigilance and tackling the challenges presented by emerging technologies and global competition.
A modernized approach to cyber risk will be an essential tool for organizations exploring how to adapt to a changing global order whose shifts are being felt across supply chains, geopolitics, and technology development. Interos’ enhanced model for evaluating cybersecurity risk across supply chains signifies a significant step towards that goal.
By expanding access to meaningful cybersecurity information, through a multi-factor, supply chain-wide approach, we can enable organizations to proactively manage and mitigate risks on a far greater scale than ever before, bringing non-cyber experts into the decision room, and fostering resilience and success in this ever-evolving global landscape.
