TL;DR

To combat rising cyber threats, financial institutions must implement effective risk assessments that combine both qualitative and quantitative analysis. These assessments should align with compliance requirements, such as FFIEC and PCI DSS, and result in a clear action plan presented to the board.

With cyber threats increasing in frequency and sophistication, financial institutions face heightened risks that can compromise sensitive data, disrupt operations, and erode customer trust. In fact, the financial services industry experienced the second highest cost of data breaches in 2024, averaging $6.08 million per incident, according to IBM's Cost of a Data Breach Report. This staggering figure underscores the importance of robust cyber security risk assessment practices to safeguard against potential threats and ensure the resilience of your institution.

Types of Risks in Financial Services

Understanding the various risks your institution faces is the first step in effective risk management in cyber security. Financial services are particularly vulnerable to several types of risks, including:

  • Operational Risks: These risks involve internal processes, systems, and personnel. Disruptions can occur due to system failures or human errors, leading to financial losses and potential harm to your institution's reputation.
  • Reputational Risks: In today’s digital landscape, a single data breach or negative incident can severely damage your institution's reputation and erode the trust of customers and stakeholders.
  • Human Risks: These risks stem from human actions, including errors, insider threats, or malicious activities by employees or third parties, which can lead to operational disruptions, data breaches, and financial consequences.
  • Environmental Risks: These risks are associated with natural disasters and extreme weather events, which can disrupt operations, damage infrastructure, and result in data loss if adequate disaster recovery plans are not in place.

Understanding Risk Assessment Compliance Requirements

A comprehensive cyber risk assessment is the cornerstone of an effective cyber security risk management strategy. Your risk assessment should be aligned with industry-standards and frameworks such as FFIEC, PCI DSS, GLBA, SOX, CCPA, or 23 NY CRR 500, which dictate the frequency and scope of assessments.

Federal Financial Institutions Examination Council (FFIEC)

The FFIEC emphasizes the importance of conducting comprehensive risk assessments as part of an institution’s cybersecurity and overall risk management strategy. These assessments should identify, measure, and prioritize risks across various domains, including information security, business continuity, and vendor management. The FFIEC Cybersecurity Assessment Tool (CAT) provides a framework for institutions to assess their inherent risks and cybersecurity maturity, ensuring they can effectively manage and mitigate those risks. Regular updates to risk assessments are encouraged to keep pace with changing threats and regulatory expectations​.

Payment Card Industry Data Security Standard (PCI DSS)

PCI DSS mandates organizations to conduct a risk assessment at least annually and whenever significant changes occur in the environment. The assessment should identify potential threats and vulnerabilities to cardholder data security and evaluate the effectiveness of current security controls. This ensures that the risk management process remains adaptive to emerging threats and operational changes​​.

Gramm-Leach-Bliley Act (GLBA)

The GLBA Safeguards Rule requires financial institutions to conduct risk assessments that identify internal and external risks to customer information security. These assessments evaluate the effectiveness of current controls and guide the development of mitigation strategies.

Sarbanes-Oxley Act  (SOX)

SOX focuses primarily on financial reporting and internal controls rather than specifically on cybersecurity risk assessments. However, it requires companies to establish robust internal control frameworks, including the evaluation of risks related to financial reporting.

California Consumer Privacy Act  (CCPA)

While CCPA does not explicitly mandate risk assessments, it requires businesses to implement and maintain reasonable security procedures to protect consumer data. Conducting regular risk assessments helps organizations evaluate the effectiveness of their data protection measures and make necessary adjustments to ensure compliance with CCPA​.

New York Department of Financial Services Cybersecurity Regulation (23 NY CRR 500)

23 NY CFR 500 requires covered entities to perform periodic, documented risk assessments tailored to their specific risks. These assessments must inform the design and ongoing adjustments of the cybersecurity program, ensuring it effectively addresses evolving threats and vulnerabilities. The risk assessment should be updated when significant changes occur within the organization or its threat environment​​.

National Institute of Standards and Technology Cybersecurity Framework (NIST CSF)

NIST CSF advises organizations to integrate risk assessments into their overall cybersecurity strategy. The framework emphasizes identifying, assessing, and managing cybersecurity risks, with a focus on continuous improvement and monitoring.

Center for Internet Security Critical Security Controls (CIS 20)

CIS 20 includes risk assessments as a critical component of its security controls. The framework recommends continuous risk assessments to identify vulnerabilities and prioritize security measures. Key controls related to risk assessment include inventorying assets, managing vulnerabilities, and controlling administrative privileges.

Choosing a Risk Assessment

Qualitative vs. Quantitative

When conducting a cyber security risk assessment, it's essential to determine whether a qualitative or quantitative approach is more appropriate.

  • Qualitative Risk Assessment: This approach involves evaluating risks based on their potential impact and likelihood, often using subjective judgment. It’s useful when precise data is unavailable but can be limited by its lack of numerical rigor.
  • Quantitative Risk Assessment: This method assigns numerical values to risks, allowing for a more objective analysis. However, it can be complex and data-intensive, making it less suitable for scenarios where detailed data is lacking.

Combining Qualitative and Quantitative Risk Assessments

Combining qualitative and quantitative risk assessments provides a more robust analysis by capturing both subjective insights and objective data. While qualitative assessments offer valuable context and expert judgment, quantitative methods add precision by assigning numerical values to risks. This dual approach allows organizations to balance the depth of understanding with measurable data, leading to more informed and well-rounded decisions. By integrating both methods, you ensure that risks are not only identified and prioritized based on data but are also contextualized within the specific operational environment, enabling more effective mitigation strategies.

6 Key Components of a Risk Assessment

An effective cyber security risk assessment should include the following key components:

  1. Inventory of Assets: Identify and document all critical assets, including hardware, software, data, and personnel.
  2. Data Classifications: Classify data based on sensitivity and importance to ensure that the most critical information is prioritized for protection.
  3. Types of Risks Applicable and Their Impact: Differentiate between risks impacting commercial activities versus investment activities, considering their distinct consequences.
  4. Measurement of Inherent Risks: Assess the level of risk in the absence of any controls or mitigation measures.
  5. Evaluation of Existing Controls: Analyze the effectiveness of current controls in place to mitigate identified risks.
  6. Calculation of Residual Risk: Determine the level of risk remaining after controls are applied, which will guide your mitigation strategies.

Best Practices for Putting Risk Assessment to Use

Once you’ve completed your cyber risk assessment, the real work begins. Here are some best practices for leveraging your findings:

Step 1 – Create an Action Plan Based on Residual Risk Calculation

Develop a prioritized action plan to address the most significant risks first, ensuring that resources are allocated efficiently. Need additional resources to help develop this action plan? Consider a vCISO engagement with ArmorPoint.

Step 2 – Partner with the Business
