Quantitative Risk models have long been applied in the financial and insurable risk fields and are now being used extensively in cybersecurity.

Quantifying risk helps manage risk by breaking it down and expressing it mathematically. Although models differ in methodology, they all produce a fundamentally similar output—a number.

What is Cyber Risk Quantification?

Cyber risk quantification determines an organization’s risk exposure and prospective financial impact in a language everyone understands -money. 

Using a single language enables technical and business leaders to prioritize spending and evaluate the overall efficacy of the cybersecurity program.

Despite gaining popularity as a bridge between security departments and business executives, cyber risk quantification still needs a deep understanding of its value to be leveraged appropriately. The benefits of CRQ in guiding financial decisions are obvious, but many companies have been slow to implement its concepts due to the ambiguity that surrounds it.

According to Deloitte’s “Future of Cyber Survey,” just half of the C-level executives polled employ any quantitative risk assessment tool. The other half continues to rely heavily on the experience of its cyber experts, maturity assessments, and other qualitative indicators to understand cyber threats.

Quantitive Vs. Qualitative Risk Assessment

Ordinal numbers (1st, 2nd, 3rd, etc.) and labels (low, medium, high) do not convey an amount. Instead, they illustrate a position or order. Ordinal numbers or labels are commonly used in cyber security to rate results or risks based on their likelihood or impact. These ordinal labels do not represent cyber security risk quantification. 

Different Q’s for different C’s

Cyber risk quantification tools should be designed to address the distinct concerns and priorities of various C-level executives within an organization. By ensuring that the strategy addresses the following questions raised by different executives, the organization can develop a robust and comprehensive approach to managing cyber risk:

CFO: Do we have enough cyber insurance coverage?

CEO: How can we demonstrate the value of security while controlling costs?

CIO: What is the estimated financial loss, given our cyber risk exposure?

CRO: What actions should we pursue to maximize risk reduction?

Business leader: How might our cyber risk exposure impact our business processes?

Models for Quantifying Cyber Risk

From qualitative assessments to quantitative analyses, organizations can leverage a range of methodologies to measure and assess their cyber risk exposure. Some common models include probabilistic risk assessment (PRA), loss distribution approach (LDA), and scenario-driven analysis. These models enable organizations to understand their cyber risk landscape better and make informed decisions about risk mitigation strategies and investments.

Probabilistic Risk Assessment (PRA)

PRA involves modeling the probabilities of various risk events and their potential consequences. It uses statistical techniques to quantify the likelihood and impact of risks, aiding in decision-making and resource allocation.

Loss Distribution Approach (LDA)

LDA focuses on modeling the distribution of potential losses resulting from risk events. It analyzes historical data, industry benchmarks, and expert judgment to estimate the frequency and severity of possible losses, providing insights into the range of financial impacts associated with different risks.

Scenario-Driven Analysis

Scenario-driven analysis involves identifying and analyzing hypothetical scenarios or “what-if” scenarios to assess the potential impact of specific risk events. It helps organizations understand the possible consequences of different risk scenarios and identify appropriate risk mitigation strategies.

Value at Risk (VaR)

VaR measures the potential losses a portfolio of assets or an organization may face within a specified confidence interval over a defined period. It provides a single numerical value to quantify the maximum loss an organization could experience under normal market conditions.

Monte Carlo Simulation

To assess potential outcomes’ range and associated probabilities, Monte Carlo simulation involves generating thousands of possible outcomes based on input variables, such as probabilities and impact factors. It helps organizations understand the uncertainty and variability inherent in risk events.

Factor Analysis of Information Risk (FAIR)

FAIR is a framework for quantifying information risk that combines elements of probabilistic risk assessment with factors such as threat frequency, vulnerability, and asset value. It aims to provide a standardized methodology for assessing and managing information risk within organizations.

Cyber VaR Model

The Cyber VaR model applies VaR concepts to quantify cyber risk, considering the likelihood of cyber incidents, the potential impact on assets and operations, and the effectiveness of existing controls. It helps organizations understand the likely financial impact of cyber threats and prioritize risk mitigation efforts.

The Centraleyes Approach to Quantifying Risk

Centraleyes works within the current cyber risk models, closely aligning with approaches like the Loss Distribution Approach (LDA). LDA, commonly used in financial institutions, assesses operational risk by estimating potential losses and their likelihood and severity. Similarly, Centraleyes combines these assessments into an annual loss distribution, much like the FAIR model does.

Step-by-Step Guide to Risk Quantification

1. Identify Critical Assets

Start by carefully inventorying all company assets within scope. Hardware, facilities, data, and software are included. The goal is to have a complete list of organizational resources.

2. Prioritization Criteria

Clearly describe asset prioritization criteria. Consider factors like revenue contribution, strategic importance in accomplishing business goals, and potential impact on daily operations. This stage aligns asset priorities with overarching organizational goals.

3. Establish a Risk Management Framework

Prior to quantification, establish a solid risk management strategy. Define your organization’s cyber risk management goals and the method you’ll be using.

4. Assess Threats and Vulnerabilities

Assess internal and external threats to your company. Understand your adversaries’ motives and capabilities to accurately quantify risk.

5.  Assess Controls

Evaluate cybersecurity controls and measures. Compare these controls to industry standards and regulations.

6.  Measure Impact and Likelihood

Using a risk equation (cybersecurity), define each risk scenario’s financial, operational, and reputational ramifications and likelihood.

7. Calculate Risk Scores

Calculate risk scores for each identified risk using a risk-scoring methodology. To rank hazards by severity, assign a numerical value to impact and likelihood.

8.  Prioritize and Mitigate

Prioritize risks by severity score and address the most important ones first. Create mitigation and action plans to reduce high-priority hazards.

9.  Monitor and Update

Monitor your company’s risk landscape, update risk assessments, and alter mitigation methods. Regularly review and improve these actions to strengthen cybersecurity.

How Does Quantification Help Risk Management?

Improved Decision-Making: By quantifying risks in monetary terms, organizations can prioritize their resources and efforts more effectively. Quantitative data enables better-informed decision-making, allowing management to allocate budgets, prioritize mitigation strategies, and invest in cybersecurity measures where they are most needed.

Resource Optimization: Quantification helps organizations identify and focus on high-impact risks that could have significant financial consequences. By understanding the potential costs associated with different risk scenarios, organizations can allocate resources more efficiently, ensuring that investments in risk management deliver the maximum value.

Enhanced Communication: Quantitative risk data provides a common language for communication between technical and non-technical organizational stakeholders. By translating complex technical risks into financial terms, organizations can effectively communicate the importance of cybersecurity to executives, board members, and other decision-makers.

Risk Monitoring and Reporting: Quantification allows organizations to monitor and track risks over time, providing valuable insights into the effectiveness of risk mitigation efforts. Regular reporting on key risk indicators helps management stay informed about emerging threats and vulnerabilities, enabling proactive risk management strategies.

Compliance and Regulatory Requirements: Many regulatory frameworks and industry standards require organizations to effectively assess and manage their cybersecurity risks. Quantification provides organizations with a systematic and structured approach to meeting these requirements, ensuring compliance with relevant regulations and standards.

Continuous Improvement: By quantifying risks and measuring the effectiveness of risk management strategies, organizations can identify areas for improvement and refine their approach to risk management over time. This iterative process enables organizations to adapt to threats and vulnerabilities, maintaining a strong cybersecurity posture in changing circumstances.

Challenges of Risk Quantification

Despite its potential benefits, risk quantification also presents challenges and limitations. One of the key challenges is the inherent uncertainty and complexity of cyber risks. Cyber threats constantly evolve, making it difficult to accurately predict and quantify their potential impact.

Additionally, risk quantification requires access to accurate and reliable data, which can be challenging to obtain, especially for emerging or novel cyber threats. Risk quantification methods may vary in complexity and applicability, requiring organizations to carefully select the most appropriate approach for their needs and circumstances.
