The New York Department of Financial Services (NYDFS) enforced cybersecurity regulations for the financial sector effective March 1, 2017, granting covered entities a 180-day compliance period. 

These regulations extend to banks, insurance companies, consumer lenders, and money transmitters, mandating encryption of data at rest, defined under 23 NYCRR 500. 

In addition to the NYDFS regulations, financial institutions must also adhere to the SEC’s new guidelines for cybersecurity management and incident disclosure, further emphasizing the critical importance of robust cybersecurity measures in the financial sector.

Compliance with this directive necessitates careful attention to detail and adherence to specific steps outlined below:

1. Inventory all financial systems

Conduct a thorough audit of all IT systems within the organization that handle financial data. This includes databases, applications, servers, and any other systems where financial information may be stored or processed. The goal is to ensure complete visibility into all systems that need to be secured and made compliant with encryption requirements.

2. Document storage mechanisms of sensitive information

Document the specific storage mechanisms used for Non-Public Information (NPI) within each system identified in the inventory. 

This documentation should include details such as:

• The types of data stored, 
• The locations of the data within the system, and 
• The encryption status (if any). 

This step is crucial for regulatory compliance and for planning the implementation of encryption measures.

3. Prioritize encryption projects

Prioritize systems and applications for encryption based on a risk-based approach. 

Consider factors such as:

• The sensitivity of the data stored, 
• The volume of data, 
• The risk of exposure, 
• Compliance obligations (such as NYDFS requirements), and 
• The potential operational impact of implementing encryption measures. 

This helps allocate resources effectively and focus on securing the most critical assets first.

4. Establish encryption standards

Adopt robust encryption standards to safeguard data at rest. NIST-compliant, 256-bit AES encryption is widely recognized as a secure and defensible encryption strategy. 

Ensure that encryption measures are implemented consistently across major operating systems used within the organization.

5. Establish key management standards

Proper key management is essential for maintaining the integrity and confidentiality of encrypted data.

• Implement a secure key management system to protect encryption keys effectively. 
• Ensure compliance with standards such as FIPS 140-2. 
• Utilize protocols like the Key Management Interoperability Protocol (KMIP) for interoperability and security. 

6. Analyze performance and operational impacts

Conduct a thorough analysis of the performance and operational impacts of implementing encryption measures. 

To anticipate any potential challenges or bottlenecks, assess factors such as: 

• CPU usage, 
• backup procedures, 
• storage requirements, and 
• overall system performance

This analysis helps in optimizing encryption implementation and minimizing disruptions to business operations.

7. Get started

Overcome potential barriers and initiate encryption projects. Secure commitment from senior management, allocate adequate IT resources, and ensure alignment with organizational objectives. 

Begin implementation with a clear plan and timeline, focusing on achieving compliance with NYDFS encryption requirements and enhancing the organization’s cybersecurity posture.

NYDFS cybersecurity regulation compliance challenges 

Complying with NYDFS cybersecurity regulation can pose challenges for financial institutions, including resource constraints, technology limitations, and evolving cyber threats. 

1. Complex regulatory landscape

Financial institutions operating in New York State encounter a complex regulatory landscape characterized by overlapping cybersecurity regulations and compliance requirements. Navigating these regulations while maintaining compliance with NYDFS cybersecurity regulations poses a significant challenge for organizations.

This necessitates:

• Thorough understanding of regulatory obligations
• Diligent compliance efforts

2. Resource constraints

Resource constraints, including limited budgets, personnel shortages, and competing priorities, present formidable challenges for financial institutions striving to achieve compliance with NYDFS cybersecurity regulation. 

3. Evolving cyber threat landscape

The dynamic and evolving nature of the cyber threat landscape poses ongoing challenges for financial institutions in mitigating cyber risks and maintaining compliance with NYDFS cybersecurity regulations. 

Adversarial tactics continue to evolve, with cybercriminals employing increasingly sophisticated techniques to exploit vulnerabilities and evade detection. 

4. Third-party risk management

Managing third-party risks presents a significant compliance challenge for financial institutions subject to NYDFS cybersecurity regulation. The interconnected nature of the financial services industry exposes organizations to cybersecurity risks associated with third-party vendors and service providers. 

To mitigate third-party risks and maintain compliance, organizations must:

• Establish robust vendor risk management programs, 
• Conduct thorough due diligence, and 
• Implement contractual safeguards

5. Legacy system vulnerabilities

Legacy IT systems and infrastructure pose inherent cybersecurity vulnerabilities for financial institutions, complicating compliance efforts with NYDFS cybersecurity regulations. 

Outdated software, unsupported hardware, and legacy applications may lack essential security features and receive limited or no vendor support, increasing the risk of cyber threats and regulatory non-compliance. Implementing strategies to modernize legacy systems, such as phased upgrades, virtualization, and cloud migration, can help address these vulnerabilities and enhance cybersecurity posture.

To overcome these challenges, organizations should consider implementing best practices such as:Investing in advanced cybersecurity technologies and threat intelligence capabilities.Enhancing employee training and awareness programs to promote a culture of cybersecurity awareness.Collaborating with industry peers and third-party service providers to share cybersecurity best practices and threat intelligence.Engaging with regulators and industry associations to stay informed about emerging cybersecurity risks and regulatory developments.
