Conducting a NYDFS NYCRR 500 (23 NYCRR Part 500) Risk Assessment, Complete Guide

The New York Department of Financial Services (NYDFS) Cybersecurity Regulation (23 NYCRR Part 500) is a cybersecurity requirement for organizations operating in New York’s financial sector. Introduced to strengthen the state’s digital defenses in 2017, the regulation focuses on protecting both consumers and institutions from cyber risks.

Today, the NYDFS Cybersecurity Regulation is central to cybersecurity compliance in the financial industry. Finalized in late 2023, the recent 23 NYCRR 500 amendments expand on key areas like governance, risk assessment, third-party oversight, and incident response. Eventually, as cyber threats continue to evolve, the expectations around financial service cybersecurity will continue to grow. More NYDFS updates are likely inevitable as a result.

Organizations subject to NYDFS oversight include banks, insurance companies, and mortgage providers. One key requirement is a cybersecurity risk assessment. Because it influences every other aspect of the cybersecurity program, a NYDFS risk assessment is often considered the most important step for compliance.

Understanding 23 NYCRR 500 is essential for covered entities. But it can also help other organizations establish an information security risk management (ISRM) program that aligns with some of the best cybersecurity requirements for financial institutions in the nation.

With this guide, organizations can better understand:

• Who should comply with NYDFS 23 NYCRR 500
• What the new NYDFS 500 requirements include
• How to conduct a NYDFS risk assessment
• How risk assessment tools can help simplify NYDFS compliance

From compliance to infosec and risk management, this guide can help teams conduct NYDFS 23 NYCRR 500 risk assessments with less uncertainty and more confidence using Isora GRC.

What is the NYDFS Cybersecurity Regulation (23 NYCRR 500)?

The NYDFS Cybersecurity Regulation, officially known as 23 NYCRR Part 500, sets baseline cybersecurity standards for financial institutions operating under the supervision of the New York Department of Financial Services (NYDFS). This regulation applies to organizations licensed, registered, or chartered under New York’s Banking, Insurance, or Financial Services Law.

Designed to strengthen financial services cybersecurity, 23 NYCRR 500 requires covered entities to implement specific controls, policies, and governance structures to protect nonpublic information (NPI) and ensure the reliability of their information systems. These standards apply to a wide range of organizations, including banks, insurers, mortgage lenders, and licensed financial service providers.

The Purpose Behind NYDFS 500

The regulation was created in response to escalating cybersecurity threats targeting the financial sector. NYDFS led the development process in close collaboration with industry stakeholders to ensure the rules addressed both existing and emerging risks.

The goal: to create a strong defense framework for the state’s financial institutions and the sensitive data they manage.

Key Milestones and Amendments

NYDFS 500 has undergone three key updates since 2017:

Who Must Comply with NYDFS 500?

The NYDFS Cybersecurity Regulation (23 NYCRR Part 500) applies to a wide range of financial institutions operating in New York. This broad scope reflects the state’s commitment to enforcing strong cybersecurity regulations in New York and ensuring consistent standards across the financial sector.

Applicability and Scope

23 NYCRR 500 is mandatory for any organization operating under or required to operate under a license, registration, charter, permit, certificate, or similar approval issued under New York’s Banking Law, Insurance Law, or Financial Services Law.

Covered entities include:

• Commercial and savings banks
• Foreign banks with branches in New York
• Insurance companies and licensed insurance agents
• Mortgage lenders and mortgage brokers
• Trust companies, credit unions, and virtual currency firms
• Other licensed or registered financial services providers in New York

These entities must meet all relevant NYDFS 500 requirements to achieve and maintain NYDFS compliance.

Classification of Covered Entities (2023 Amendments)

The 23 NYCRR 500 amendments introduced three key categories of covered entities to tailor compliance expectations based on company size and complexity:

Employees, agents, designees, and wholly owned subsidiaries of covered entities are fully exempt from the regulation.

Third-Party Service Provider Requirements

NYDFS 500 also extends to third-party service providers that access or process nonpublic information (NPI) on behalf of covered entities. Organizations must:

• Conduct due diligence on third-party vendors
• Ensure proper cybersecurity protections through contracts
• Monitor third-party compliance with applicable NYDFS 500 requirements

This ensures consistent financial services cybersecurity, even when data is shared with external partners.

What Are the Core Requirements of NYDFS 500?

The NYDFS Cybersecurity Regulation (23 NYCRR Part 500) outlines a structured set of cybersecurity requirements designed to protect NPI and ensure the security of New York’s financial services sector. Each section of the regulation focuses on a specific area of governance, control, or risk mitigation.

NYDFS 500 Requirements at a Glance

How to Conduct a NYDFS 500 Risk Assessment

A NYDFS risk assessment is the process of identifying, evaluating, and documenting cybersecurity risks to an organization’s information systems and nonpublic information, then using those results to shape the information security risk management program, policies, and controls.

NYDFS NYCRR expects covered entities to:

• Follow the requirements outlined in Part 500’s clauses.
• Base the cybersecurity program and written policies on the results of a risk assessment (§500.2, §500.3).
• Use a recognized control framework to structure the risk assessment so it is comprehensive, consistent, and repeatable.

A well-documented and regularly updated risk assessment is central to compliance under 23 NYCRR Part 500. More specifically, §500.09 requires covered entities to:

• Perform and document a risk assessment at least annually.
• Update the assessment whenever material changes in business operations, technology, or threat landscape occur.
• Use the assessment results to inform and adjust policies, controls, and procedures.

NYDFS is framework-agnostic, meaning it does not require a specific risk assessment framework. But DFS examiners often prefer to see alignment with nationally recognized models like NIST SP 800-30.

Why Use NIST SP 800-30 for NYDFS?

NIST SP 800-30 is a cybersecurity risk assessment framework that organizations can use for NYDFS NYCRR 23 Part 500 compliance. It outlines a four-step approach to conducting risk assessments:

1. Plan the Assessment
2. Conduct the Assessment
3. Communicate the Assessment Results
4. Maintain the Assessment

One disadvantage of NIST SP 800-30 is that it was designed as a threat-based model, meaning it starts with hypothetical threat scenarios and then works forward to estimate risk. Because it relies heavily on assumptions rather than evidence, this type of approach often comes with certain limitations. As a result, NIST SP 800-30 risk assessments can be:

• Resource-intensive and highly subjective
• Impractical for organizations with complex, cloud, or hybrid environments
• Difficult to defend to regulators

Instead, a control-based approach to NIST SP 800-30 flips the entire risk assessment process around to yield better results.

Why Use a Control-Based Model for NYDFS Risk Assessments?

A control-based risk assessment verifies the actual implementation status of controls rather than speculative threats. Then, it analyzes those results in the context of the asset’s role, data sensitivity, and exposure to determine the likelihood and impact. This method:

• Anchors risk ratings in observable, testable evidence.
• Naturally aligns with NYDFS’s clause structure, since most obligations are control-based
• Produces more defensible outputs because it’s traceable to specific control failures and regulatory requirements
• Generates prioritized, actionable findings for decision-makers, not generic “threat” statements

When implemented with a tool like Isora GRC, a control-based NIST SP 800-30 risk assessment is scalable across systems and vendors. Here, mappings between controls and NYDFS clauses are consistent, registers are evidence-ready, and reports are instantly available without rework.

Step-by-Step Guide to NYDFS NYCRR 500 Risk Assessment

A control-based implementation provides a proven, defensible structure for meeting NYDFS NYCRR Part 500 obligations. The rest of this guide breaks down each step of the NIST SP 800-30 risk assessment process and how to execute it in a way that meets every relevant NYDFS clause.

More specifically, it explains exactly how the four phases of a control-based NIST SP 800-30 model align with NYDFS requirements.

Here’s how to execute each of the four steps outlined in NIST SP 800-30 using a control-based approach that satisfies NYDFS Part 500 requirements.

Step 1 – Prepare for the Assessment

Preparation is the most important step of an NYDFS 23 NYCRR Part 500 risk assessment. It sets the scope, governance, inventory, control mapping, and evidence requirements that will determine whether the assessment is compliant and useful for security decision-making.

Under §500.9, this step also defines when and how to update risk assessments – at least annually and whenever material business or technology changes occur.

A control-based NIST SP 800-30 risk assessment grounds every decision in observable control data, system context, and regulatory requirements. The result of Step 1 is a documented, approved plan with:

• A scope tied to the cybersecurity program and policy
• Governance with named owners and board oversight
• An accurate, complete, validated asset inventory
• A mapped control set aligned to NYDFS clauses
• A detailed evidence plan with timelines and escalation paths
• Vendor coverage integrated into the same risk workflow

Today, keeping these foundations consistent, scalable, and traceable is easier with an NYDFS risk assessment platform like Isora GRC.

Define Scope and Purpose

NYDFS requires organizations to base their cybersecurity programs (§500.2) and written policies (§500.3) on the risk assessment. In most cases, the assessment’s scope must be explicitly linked to program design and policy coverage as a result. The scope should:

• State the purpose. Is it an annual review, vendor onboarding, post-merger integration, or post-incident reassessment?

• List in-scope assets. Include systems, applications, and vendors, identifying where nonpublic information (NPI) is stored, processed, or transmitted.

• Record exclusions. Document rationale (e.g., systems covered under another regulated entity’s program).

• Define updated triggers. Note any material changes in business operations, technology, or threat landscape (§500.9).

• Describe outputs. Explain how results will impact updates to policies, controls, and program elements.

A well-defined scope makes assessments NYDFS-compliant, but it also helps keep them focused on what matters most to the organization’s risk posture.

Establish Governance and Roles

Governance is what gives NYDFS risk assessments authority, accountability, and a clear path to decision-making. Section 500.4 explicitly requires a designated Chief Information Security Officer (CISO) to oversee the cybersecurity program, including the risk assessment. Key governance elements include:

• CISO appointment: Document authority, whether internal or outsourced, and identify the senior officer with oversight responsibility if outsourced.

• Executive sponsor: A senior leader empowered to allocate resources and accept risk.

• Defined responsibilities: Assign owners for coordination, evidence collection, and review – formalized in a RACI matrix.

• Board oversight: The board or senior governing body must receive the CISO’s annual report covering program status, material risks, material incidents, and remediation plans (§500.4(b)). Build this review into the assessment timeline.

Build and Validate the Asset Inventory

The asset inventory is both a compliance requirement (§500.13) and the foundation for accurate control mapping. Without it, organizations can’t credibly determine which systems to assess or where NIP is at risk. A NYDFS-compliant inventory should:

• List the owner, location, classification, retention period, recovery time objective (RTO), and support end-of-life status for each asset.
• Identify NPI-handling systems explicitly.
• Be updated and validated on a documented cadence.
• Include secure-disposal procedures for any NPI no longer required, with exceptions documented for legal or operational reasons.

Remember, Class A organizations must be ready for the November 1, 2025, deadline for implementing an asset inventory.

Select Framework and Control Mappings

NYDFS NYCRR Part 500 is a cybersecurity regulation, not a control framework. It contains prescriptive requirements (“must do X”) and risk-based obligations (“must determine X based on the risk assessment”). But it does not provide a complete, detailed library of security controls with implementation guidance.

Instead, organizations need a separate control framework to conduct an effective NYDFS risk assessment.

How to Choose a Control Framework for NYDFS?

Control frameworks like NIST CSF, NIST SP 800-53, CIS Controls, and ISO 27001 Annex A provide catalogs and detailed implementation guidance for security controls. Ideally, organizations will select a framework that fits their operating environment and compliance landscape.

Common control frameworks include:

• NIST CSF 2.0 is widely recognized and works well for aligning with NYDFS’s risk-based approach.

• CIS Controls are highly prescriptive and often preferred for operational teams.

• ISO 27001 supports integration with enterprise risk management.

Also important to consider is compliance overlap – organizations subject to GLBA, PCI DSS, HIPAA, or SOX should choose a framework that maps to those standards, too. And, don’t forget to plan for mapping to NYDFS. Make sure to cover specific clauses, including:

• §500.5 Vulnerability Management
• §500.6 Audit Trail
• §500.7 Access Privileges and Management
• §500.12 Multi-Factor Authentication

How to Map Controls to NYDFS?

Here’s exactly how to map controls to NYDFS Part 500 in a control-based NIST SP 800-30 risk assessment:

1. Start with the chosen framework’s control list. NIST CSF Categories, NIST 800-53 AC, AU, SC families, CIS Safeguards.

2. Create a crosswalk. Link each control to the NYDFS clauses it supports. Example:

• NIST 800–53 AC-2 (Account Management) → §500.7 Access Privileges and Management
• CIS Controls 6.2 (Activate MFA) → §500.12 Multi-Factor Authentication

3. Filter by relevance. Use the asset inventory to decide which controls apply to which system, application, or vendor. Consider data classification, exposure, and business function.

4. Document rationale. For each mapping, note why the control is needed for the asset and how it supports the NYDFS requirements.

Define Evidence Collection Methods

NYDFS expects assessments to be based on enough credible information. The evidence collection plan must detail exactly how teams should verify control implementation. To collect evidence, organizations should:

• Use structured questionnaires for consistency across systems and vendors.
• Require supporting documentation for each control (e.g., screenshots, logs, policies, configuration exports).
• Incorporate automated collection for technical controls where feasible, particularly those tied to §500.5, §500.6, and §500.12.
• Set clear deadlines and escalation paths for non-responses.

Linking each evidence requirement to a specific NYDFS clause will make proving coverage easier during DFS examinations.

Address Third-Party Service Providers

Section 500.11 requires a third-party security policy based on the risk assessment. To meet it:

• Identify in-scope vendors with access to systems or NPI.
• Develop vendor-specific questionnaires covering MFA, encryption, access controls, and audit rights.
• Plan to integrate vendor findings into the same risk register used for internal systems.

With this foundation in place, the next step is a straightforward execution of data collection, gap identification, and risk scoring, all traceable back to NYDFS requirements.

Step 2 – Conduct the Assessment

Once preparation is complete, the next task is to collect evidence, verify control implementation, and document the gaps and conditions that shape the organization’s risk profile. NYDFS §500.9(a) requires that the risk assessment:

• Identify risks to information systems and NPI.
• Evaluate the sufficiency of existing controls.
• Capture findings in an actionable and auditable format.

A control-based NIST SP 800-30 approach grounds this step in observable control performance and asset context instead of speculative threat modeling. By the end of Step 2:

• Every entry in the register is backed by evidence, tied to an NYDFS clause, and scored using consistent criteria.
• Gaps and predisposing conditions are documented in language that a regulator or auditor can test.
• The register is ready for stakeholder review and action in Step 3.

Isora GRC can streamline this step by generating clause-specific questionnaires, tracking evidence submissions, and auto-populating a risk register aligned to the scoring model to reduce manual tracking and make sure no NYDFS requirement is missed.

Distribute Questionnaires and Collect Evidence

Structured questionnaires are the most effective way to gather consistent, scalable input from control owners, vendors, and other assessment participants. Tailor each questionnaire to the control mappings and asset inventory defined in Step 1.

For each mapped control, request:

• Implementation status: Fully implemented, partially implemented, or not implemented

• Evidence: Screenshots, configuration exports, log extracts, policy excerpts

• Clarifications: Wherever responses are vague, incomplete, or missing

Cover every NYDFS clause that depends on risk-based verification, including:

• Cybersecurity program (§500.2) and policy (§500.3)
• Governance/reporting (§500.4)
• Vulnerability management (§500.5)
• Audit trail (§500.6)
• Access privileges (§500.7)
• Application security (§500.8)
• Third-party service provider security (§500.11)
• Multi-factor authentication (§500.12)
• Asset inventory and data retention (§500.13)
• Monitoring and training (§500.14)
• Encryption (§500.15)
• Incident response and BCDR (§500.16)

For vendors, base questionnaires on the third-party security policy (§500.11). Confirm contractual obligations – MFA, encryption, audit rights, and log retention – are implemented as agreed. Track completion rates and escalate non-responses according to the timelines defined in Step 1.

Identify Control Gaps, Vulnerabilities, and Predisposing Conditions

Review each response against the control requirement and the corresponding NYDFS clause. Define gaps in clear, testable terms. Examples include:

• §500.5: No external penetration test in the last 12 months; automated scans not run after significant system changes; no process for vulnerability intel intake; remediation not prioritized by risk.
• §500.6: Transaction logs not retained for five years; security event logs not retained for three years; missing or incomplete audit trail capability.
• §500.7: No documented periodic access reviews; excessive privileged accounts; no least-privilege enforcement.
• §500.12: MFA missing for privileged accounts or third-party applications handling NIP; compensating controls not CISO-approved in writing or reviewed annually.
• §500.13: Asset inventory missing required fields; not validated on schedule; no secure disposal process for NPI.
• §500.14: No user activity monitoring; missing anti-malware/web/email protections; no annual training included social engineering scenarios.
• §500.15: NPI not encrypted in transit or at rest; compensating controls missing or not reviewed annually.
• §500.16: Incident response or BCDR plan missing recovery steps, communication protocols, or post-incident review process.

Also record predisposing conditions – environmental or architectural factors that increase the likelihood of a control failure being exploited:

• Internet-facing systems without MFA
• Unsupported or unpatched software
• Lack of endpoint detection or centralized logging where required
• Flat network topology without segmentation

Link each condition to the relevant NYDFS clause in the notes.

Analyze and Score Risks

For each confirmed control gap, link it to a plausible adverse event and score it using the likelihood and impact scales defined in Step 1. Use real context to inform scoring:

• Likelihood: Higher if the control failure involves a high-exposure asset, inadequate patching, or weak access controls
• Impact: Consider data classification, system criticality, operational downtime, potential fines, and reputational harm

Use risk-based mandates to anchor severity and timelines. Example mappings include:

• §500.5: Set scan cadence and prioritize remediation by risk; high-risk vulnerabilities demand near-term fixes.
• §500.6: Logs that cannot detect or reconstruct events create high impact due to detection and obligations
• §500.7 / §500.12: Excess privileges or missing MFA increase the likelihood of unauthorized access.
• §500.15: Unencrypted NPI drives higher impact ratings due to confidentiality loss.

Document a short rationale for each rating to preserve scoring transparency, support auditability, and explain prioritization decisions later on.

Update the Risk Register

The next step is to enter risks into a structured register. Make sure each entry includes:

• Risk title and description
• Associated control gap and NYDFS clause
• Likelihood and impact ratings
• Affected system, business unit, or vendor
• Predisposing conditions
• Assigned owner and date identified

The risk register is the operational link between the assessment and remediation planning. It’s also the evidence DFS expects under §500.4(b) and §500.9(b) to show that risks have been identified, rated, and assigned, and the basis for the annual compliance certification under §500.17(b).

Now, the risk register is ready for stakeholder review and action in Step 3.

Step 3 – Communicate and Respond to Risk

Once risks are identified and scored, they must be reviewed, assigned, and acted upon. Under §500.9(b), covered entities must develop mitigation plans or determine an appropriate response for each risk, document those decisions, and track them through completion.

This step makes sure every gap found in Step 2 is either closed, accepted with justification, transferred, or avoided – and that leadership has the information needed for oversight. By the end of Step 3:

• Every risk is validated, has a documented decision, and is assigned to an accountable owner.
• The rationale for each decision is recorded and tied to the relevant NYDFS clause.
• Mitigation actions are embedded in operational workflows and tracked to completion.

Isora GRC can centralize this process by linking risks to NYDFS clauses, storing decision rationales, assigning tasks with due dates, and producing board-ready reporting with real-time progress data.

Review and Validate the Risk Register

The risk register is the authoritative record of all identified risks. Before making decisions:

• Verify completeness. Every entry should name the control gap, the NYDFS clause it relates to, and the affected asset or vendor.

• Check accuracy. Make sure likelihood and impact ratings match the evidence and reflect current system conditions.

• Confirm context. Predisposing conditions and related system details should be documented for each entry.

• Assign ownership. Each risk must have a responsible owner with authority to remediate, accept, or otherwise resolve it.

Hold stakeholder review sessions with the CISO, executive sponsor, department heads, and system owners. Encourage challenges to ratings and document any adjustments made.

This step satisfies the governance and oversight requirements under §500.4(b), keeps discussions grounded in validated data, and makes sure the register will support decision-making and annual board reporting.

Select and Document Risk Responses

Part 500 does not dictate which risks to mitigate, but it does require that the program be risk-based and that decisions be documented. For each risk, select one of four responses:

• Mitigate: Implement or strengthen controls to reduce the likelihood or impact.
• Accept: Take no immediate action when residual risk is low, well-understood, and within risk appetite.
• Transfer: Shift responsibility for the risk to a third party via a vendor contract or cyber insurance.
• Avoid: Eliminate the source of risk by discontinuing the system, service, or practice causing it.

For each decision:

• Document rationale. Reference cost-benefit considerations, regulatory obligations, operational constraints, and risk appetite alignment.

• Assign an action owner and due date. For mitigations, align timelines with any NYDFS-specific expectations (e.g., remediation priorities under §500.5).

• Map follow-on actions. Link the decision to related clauses if other controls need updating (e.g., policy changes under §500.3, vendor requirements under §500.11).

[H3] Communicate Decisions and Track Progress

Risk decisions must be communicated to all impacted stakeholders, and progress must be tracked until each risk is closed, accepted, or transferred. Key activities include:

• Notify assignees. Give clear instructions on actions, deadlines, and evidence requirements to control owners, business unit leads, and third-party providers.

• Integrate into workflows. Log remediation tasks in a ticketing or project management system (e.g., Jira, ServiceNow) for visibility.

• Monitor progress. Use dashboards or regular reports to track open risks, mitigation completion rates, and the number and age of accepted risks.

• Review status regularly. Hold status meetings for high and moderate risks, especially those tied to regulated systems or NPI.

Under §500.4(b), the CISO’s annual written report to the board or senior governing body must include:

• The status of the cybersecurity program
• Material risks identified
• Material cybersecurity events
• Plans to remediate material inadequacies

The validated risk register – paired with progress metrics – is the backbone of this report and is essential for demonstrating informed oversight.

Step 4 – Maintain the Assessment

A NYDFS risk assessment is not a one-and-done exercise. Section 500.9(a) requires it to stay current, which means keeping it aligned with the organization’s actual systems, controls, and threat environment.

In practice, this step is about making sure the assessment stays useful for decision-making, supports the CISO’s annual reporting under §500.4(b), and keeps the organization prepared for DFS examinations at any point in the year. By the end of Step 4:

• The assessment reflects the real environment at all times.
• Risk data is refreshed on a defined cadence and after material changes.
• Evidence is maintained to prove compliance without scrambling.
• Accurate, up-to-date records back NYDFS certifications and notifications.

Isora GRC can automate change tracking, flag when reassessments are due, keep the risk register synchronized with asset and control changes, and generate clause-specific reports for board review or DFS requests in minutes.

Monitor for Changes that Affect Risk

Risk profiles shift whenever the environment changes. Maintaining accuracy means continuously tracking:

• System and asset changes: Additions, decommissions, migrations to new platforms, or changes in ownership/administration (§500.13)

• Control changes: Newly implemented, retired, or altered controls, including temporary workarounds that have become permanent (§500.2, §500.3)

• Data and usage changes: Assets beginning to handle more sensitive data, higher uptime requirements, or expanded user access (§500.15)

• External factors: New regulatory requirements, emerging threats, vulnerability advisories, changes in vendor security posture (§500.11, §500.14)

Trigger events for an immediate reassessment include mergers or acquisitions, significant architecture changes, major vendor onboarding/offboarding, security incidents, or shifts in compliance obligations.

Reassess Controls and Update the Risk Register

The register must reflect current conditions to be useful. A control-based approach means periodically redistributing questionnaires, revalidating evidence, and re-scoring risks. When a trigger event or scheduled reassessment occurs:

• Redistribute questionnaires to affected control owners and vendors, targeting only the systems or processes that changed.

• Collect updated evidence and revalidate implementation status.

• Re-score risks: Downgrade where controls are now in place, escalate if exposure has increased.

• Close resolved risks: Attach verification (logs, configs, signed policy updates) before marking as closed.

Use this process to ensure:

• §500.5 Vulnerability Management activities are happening on the required cadence.
• §500.12 MFA is enforced for any new systems or accounts.
• §500.15 Encryption status is reviewed at least annually.
• §500.13 Asset Inventory is validated, and secure disposal of NPI is documented.

This process directly supports §500.9’s requirement to update the risk assessment when material changes occur and ensures the CISO’s board reporting is based on accurate, timely data.

Institutionalize Ongoing Risk Monitoring

To meet NYDFS expectations and avoid compliance gaps between formal assessments, risk maintenance must be embedded into everyday operations. To institutionalize ongoing risk monitoring, organizations can:

• Hold quarterly risk review meetings. Review open risks, accepted risks nearing review dates, and mitigation progress.
• Embed risk checkpoints into IT workflows. Change management, procurement, and vendor onboarding should all include a risk control review step.
• Maintain visibility via dashboards. Track the number of open risks by severity and NYDFS clause, mitigation status, overdue actions, and accepted risks approaching review deadlines.
• Assign permanent ownership. A GRC, security, or enterprise risk team should manage the register, initiate reassessments, and coordinate with business units.

Maintain Evidence and Meet Certification Obligations

DFS examiners can request proof of compliance at any time. Always keep:

• Risk assessment reports, scoring documentation, and the current risk register
• Board reports and meeting minutes showing risk oversight (§500.4(b))
• Evidence of control implementation and remediation activity
• Audit trail logs meeting retention requirements (§500.6)

Also, make sure to meet Part 500 reporting requirements:

• Annual certification (§500.17): Submit by April 15, supported by the current register and evidence.

• 72-hour incident notifications (§500.17): Integrated into the incident response plan (§500.16).

• Ongoing updates to DFS during incident handling.

Risk assessment is the foundation of a compliant cybersecurity program. Section 500.09 requires all covered entities to:

• Perform and document a risk assessment annually
• Update the assessment when business or tech changes cause a material impact
• Use results to adjust policies, controls, and procedures

While NYDFS 500 is framework-agnostic, regulators favor alignment with nationally recognized frameworks like NIST SP 800-30. Below is a step-by-step alignment example:

How Does NYDFS 500 Compare to NIST CSF?

Although the NYDFS Cybersecurity Regulation (23 NYCRR Part 500) does not explicitly map to any one framework, it shares several foundational principles with the NIST Cybersecurity Framework (CSF). The 2023 amendments to 23 NYCRR Part 500 reference NIST in the enforcement section, noting that regulators may consider a company’s alignment with recognized frameworks, like NIST, when determining penalties or assessing the strength of cybersecurity programs:

Practical Takeaway

For financial organizations working toward NYDFS compliance, aligning internally with NIST CSF can:

• Make audits and board reporting easier
• Improve risk assessment structure
• Demonstrate a proactive cybersecurity posture in case of enforcement actions

Although not required, using NIST CSF as a companion framework can enhance program maturity and streamline financial services cybersecurity operations, without compromising compliance with NYDFS 500 requirements.

NYDFS 500 FAQs

What are the penalties for failing NYDFS cybersecurity compliance?

Noncompliance with NYDFS 500 can result in regulatory investigations, penalties, and reputational damage. NYDFS has the authority to enforce civil fines and demand corrective actions. Covered entities must demonstrate a good-faith effort toward compliance or risk disciplinary actions based on the severity and scope of violations.

How frequently must cybersecurity policies be reviewed under 23 NYCRR 500?

Cybersecurity programs should be reviewed and updated at least annually. However, updates are also required whenever material changes in business operations, technology, or threat environment occur. This ensures that the program continues to align with the organization’s current risk landscape and satisfies Section 500.2 requirements.

Do NYDFS 500 rules apply to cloud vendors?

Yes. Cloud providers are classified as third-party service providers if they access, store, or process nonpublic information (NPI) on behalf of a covered entity. Organizations must vet these providers for adequate security controls and document contractual obligations as outlined in Section 500.11.

Why is risk assessment critical to NYDFS cybersecurity compliance?

Risk assessments are foundational. They directly inform cybersecurity policies, control implementations, third-party oversight, and incident response planning. Without a current, documented risk assessment, it’s difficult to justify the adequacy of other compliance actions under NYDFS 500.
