The Evolving Cybersecurity Landscape: Threats to the Financial Sector
In today’s digital age, the financial sector, including credit unions, faces an increasingly sophisticated array of cybersecurity threats that demand vigilance. The rapid evolution of technology, coupled with escalating geopolitical tensions, has expanded the threat landscape significantly. Financial institutions are particularly vulnerable due to their increasing reliance on technology and third-party service providers that are beyond the regulatory purview of agencies like the National Credit Union Administration (NCUA).
The NCUA remains deeply concerned about the risks cyberattacks pose to the financial system. As threats evolve, become more sophisticated, and cause greater damage across various industries, the cybersecurity risks facing the credit union sector continue to grow. Geopolitical tensions increase the possibility of nation-states and other sophisticated actors conducting malicious cyberattacks against U.S. critical infrastructure, of which credit unions are a significant part.
To ensure the long-term success of the credit union industry, institutions must deliver member services using appropriate controls and maintaining robust cybersecurity practices. The evolving array of cybersecurity threats that require continued vigilance by credit unions include:
-
Third-Party Vulnerabilities: The reliance of credit unions on third-party vendors for essential services exposes them to additional cybersecurity risks, which is a growing regulatory blind spot for the NCUA due to the lack of authority over these third-party providers.
-
Geopolitical Risks: Heightened geopolitical tensions increase the likelihood of nation-state-sponsored cyberattacks targeting critical infrastructure, including the financial sector.
-
Advanced Cybercrime Tactics: Cybercriminals are constantly developing new and sophisticated techniques, such as ransomware, phishing, and supply chain attacks, to compromise systems and disrupt operations.
-
Insider Threats: Malicious insiders, whether current or former employees, can pose significant risks to an organization’s cybersecurity and the integrity of its systems and data.
-
Internet of Things (IoT) Vulnerabilities: The proliferation of IoT devices in the financial sector introduces new attack vectors that can be exploited by threat actors.
Strengthening Cybersecurity Resilience: The NCUA’s Comprehensive Approach
The NCUA is committed to fortifying cybersecurity resilience within the agency and the credit union system. Through targeted examinations, comprehensive risk assessments, and robust educational outreach initiatives, the NCUA is working diligently to strengthen cybersecurity practices and mitigate potential vulnerabilities across the industry.
Enhancing Cybersecurity Oversight and Reporting
One of the NCUA’s key initiatives to improve cybersecurity preparedness is the implementation of the Information Security Examination (ISE) program. The ISE program uses a risk-focused, scalable approach to examine credit unions’ information security programs, providing examiners the flexibility to focus on areas of current or potential material risk relevant to each credit union’s unique business model.
Additionally, in February 2023, the NCUA Board approved a final rule that requires federally insured credit unions to notify the NCUA as soon as possible, within 72 hours, after a credit union reasonably believes that a reportable cyber incident has occurred. This rule ensures timely reporting of cyber incidents, enabling the NCUA to respond and mitigate threats more effectively.
Leveraging Cybersecurity Tools and Resources
To assist credit unions in enhancing their cybersecurity posture, the NCUA provides several resources and tools, including the Automated Cybersecurity Evaluation Toolbox (ACET). The ACET is a voluntary maturity assessment tool that allows credit unions to determine the maturity of their information security programs and align their practices with industry standards and regulatory guidance.
The NCUA also collaborates with other regulatory agencies, such as the Federal Financial Institutions Examination Council (FFIEC) and the Financial and Banking Information Infrastructure Committee (FBIIC), to develop and implement cybersecurity policies and standards across the financial industry. These partnerships enable the NCUA to stay abreast of emerging threats and best practices, further strengthening the credit union system’s cybersecurity resilience.
Enhancing Internal Cybersecurity Posture
To lead by example, the NCUA has made significant investments in prioritizing its own cybersecurity resilience and adopting a Zero-Trust Architecture (ZTA). These investments are designed to identify, deter, protect against, detect, and respond to persistent and increasingly sophisticated cyber campaigns, meeting and exceeding the standards outlined in the latest Office of Management and Budget directives.
The NCUA’s approach includes implementing multi-factor authentication, utilizing secure virtual private network (VPN) connections, leveraging security information and event management solutions, and automating threat analysis through a threat intelligence platform. Additionally, the agency has established redundant data center facilities and migrated critical public-facing web services to cloud-based infrastructure to enhance resilience and mitigate risks resulting from infrastructure failures.
Empowering Credit Unions through Training and Outreach
The NCUA recognizes the importance of empowering credit unions through training and educational initiatives. The agency’s Office of Credit Union Resources and Expansion provides a comprehensive online training system with over 200 courses on various topics, including information security. Additionally, the NCUA hosts regular webinars to deliver timely and meaningful information to help credit union professionals stay current on relevant cybersecurity threats and best practices.
The NCUA also invests in specialized personnel, such as regional Information Systems Officers and subject matter examiners, to ensure that credit unions receive expert guidance and support in navigating the complex cybersecurity landscape.
Overcoming Regulatory Challenges: The Need for Expanded Authorities
Despite the NCUA’s proactive efforts to enhance cybersecurity resilience within the credit union system, challenges persist, particularly concerning the lack of authority over third-party vendors. The reliance of credit unions on third-party providers for essential services exposes them to additional cybersecurity risks, which the NCUA is unable to effectively manage or mitigate due to this regulatory blind spot.
Independent entities, such as the Government Accountability Office, the Financial Stability Oversight Council, and the NCUA’s Office of Inspector General, have all identified this deficiency as a significant obstacle to the NCUA’s mission to safeguard credit union members and the financial system. These entities have repeatedly recommended that Congress provide the NCUA with the necessary authority to examine and supervise third-party service providers.
Addressing this regulatory gap is crucial, as it would significantly improve the NCUA’s supervisory oversight and bolster its ability to mitigate cybersecurity risks, ultimately enhancing the credit union system’s overall security posture and the protection of critical infrastructure in the United States more broadly.
Conclusion: Embracing a Collaborative Approach to Cybersecurity Resilience
The NCUA remains committed to adapting its cybersecurity approach to effectively address emerging threats and challenges. By leveraging partnerships with other federal agencies, industry stakeholders, and cybersecurity experts, the NCUA continues to foster a collaborative environment conducive to information sharing and coordination.
This collaborative approach enables the NCUA to stay abreast of current and emerging threats, enhancing its ability to anticipate and respond effectively to cybersecurity risks. However, to fully realize the benefits of this collaborative effort, the NCUA requires the necessary statutory authority to oversee and mitigate risks posed by third-party service providers.
By remaining vigilant and proactive, the NCUA aims to defend the security and stability of the credit union system, promoting the financial well-being of credit union members and safeguarding the integrity of the broader financial system for generations to come. Through a comprehensive and collaborative approach, the NCUA is well-positioned to protect critical infrastructure and maintain operational resilience in the face of evolving cybersecurity threats.
