New York DFS (23 NYCRR 500) Compliance
Le règlement NYDFS en matière de cybersécurité exige que les entités financières concernées réalisent annuellement des tests d’intrusion et des évaluations de vulnérabilité. Découvrez comment ImmuniWeb soutient la section 500.5.
Conformité à la réglementation de cybersécurité du New York DFS
What Is the NYDFS Cybersecurity Regulation?
Part 500 requires each Covered Entity to maintain a risk-based cybersecurity program with prescriptive controls: a risk assessment, a CISO, multi-factor authentication, encryption, access controls, monitoring and logging, an asset inventory, incident notification within 72 hours, and an annual certification signed by the CEO and CISO.
The Second Amendment added board-level oversight, expanded notification, automated vulnerability scanning with manual review, and additional requirements for larger 'Class A' companies. The annual certification creates personal accountability for senior officers.

Who Must Comply with NYDFS Part 500?
Part 500 applies to Covered Entities:
- Banques et prêteurs agréés ou autorisés par la NYDFS.
- Insurance companies operating under NYDFS authorization.
- Other financial services entities (including mortgage providers); larger 'Class A' companies face additional requirements.
The web, mobile and API applications these entities run are within the scope of Part 500's testing requirements.
Key NYDFS Requirements for Application Security
Application security is driven by Section 500.5:
- 500.5(a) - Penetration testing: annual penetration testing of information systems based on the risk assessment.
- 500.5(b) - Vulnerability assessments: bi-annual vulnerability assessments, including automated scans and manual review of systems.
- Monitoring and remediation: monitor for, and remediate in a timely way, vulnerabilities found.
NYDFS Part 500 Requirements in Depth
Section 500.5 - Penetration Testing and Vulnerability Assessments
Section 500.5 requires annual penetration testing of information systems based on the risk assessment, plus bi-annual vulnerability assessments including automated scans and manual review of systems not otherwise covered. Penetration testing and scanning of web and mobile applications and APIs satisfy these requirements directly.
Application Security in the Program
Beyond 500.5, the program's monitoring, access-control and risk-assessment requirements all touch application security. Continuous scanning and periodic penetration testing, with tracked remediation, keep the program effective and evidence-ready.
Risques courants des applications Web et mobiles à remédier
The vulnerabilities Section 500.5 expects you to find map closely to the OWASP Top 10:
- Contrôle d'accès cassé — des utilisateurs accédant à des données ou actions interdites.
- Échecs cryptographiques — chiffrement faible ou absent exposant des données sensibles.
- Injection — Injection SQL, de commande ou autre via des entrées non validées.
- Insecure Design — contrôles de sécurité manquants par conception, pas seulement à cause d'un bug.
- Mauvaise configuration de sécurité — configuration par défaut, incomplète ou non sécurisée.
- Vulnerable & Outdated Components — unpatched libraries and frameworks.
- Identification & Authentication Failures — weak login, session or credential handling.
- Software & Data Integrity Failures — untrusted updates, insecure CI/CD pipelines.
- Échecs de journalisation et de surveillance de la sécurité — les attaques passent inaperçues.
- Server-Side Request Forgery (SSRF) — the server tricked into making malicious requests.
For mobile apps, the OWASP Mobile Top 10 is the equivalent reference (insecure data storage, insecure communication, weak cryptography, and so on). Reliably finding these issues requires testing the running application, not just a documentation review.

How ImmuniWeb Helps You Achieve NYDFS Part 500 Compliance
ImmuniWeb supports Section 500.5 with the penetration testing and vulnerability assessments NYDFS requires, with audit-ready evidence.
| Exigence | Ce que cela nécessite | Produits ImmuniWeb |
|---|---|---|
| 500.5(a) | Annual penetration testing. | On-Demand, MobileSuite |
| 500.5(b) | Bi-annual vulnerability assessments (scans + review). | Neuron, Discovery |
| Program & remediation | Monitor and remediate; secure development. | Continuous, On-Demand |
ImmuniWeb On-Demand and MobileSuite deliver web and mobile penetration testing; Neuron and Neuron Mobile provide automated scanning; Continuous embeds testing into CI/CD; and Discovery maps the attack surface - producing evidence for the annual NYDFS certification.
NYDFS Part 500 vs International Frameworks
Si vous respectez déjà des normes internationales, les mêmes tests ImmuniWeb les couvrent toutes:
| Framework | Perspective sécurité des applications | Comment ImmuniWeb s'aligne |
|---|---|---|
| NYDFS Part 500 | 500.5 pentest + vulnerability assessments | Tests d’intrusion Web/mobile + scans + ASM |
| FTC Safeguards Rule | 314.4(d) testing | Les mêmes tests couvrent les deux |
| EU DORA | Resilience testing | Les mêmes tests couvrent les deux |
| NIST CSF 2.0 | Protect / Detect functions | Tests et surveillance des applications |
Tests d'intrusion vs scans de sécurité
Les deux sont nécessaires. Le scan automatisé (DAST) offre une couverture large et fréquente et est idéal pour les tests continus dans le CI/CD ; le penetration testing manuel trouve les vulnérabilités de logique métier et complexes que les scanners manquent et produit la profondeur attendue par les auditeurs et les régulateurs. Combinez le scanning continu avec du penetration testing manuel périodique, et re-testez après des changements significatifs.
Liste de contrôle de conformité (Sécurité des applications)
- Inventory of internet-facing financial apps and APIs
- Annual penetration testing performed (500.5(a))
- Bi-annual vulnerability assessments performed (500.5(b))
- Automated scans plus manual review in place
- Findings remediated and re-tested; evidence retained
- Incident notification process ready (72 hours)
- Evidence prepared for the annual CEO/CISO certification
Why NYDFS Part 500 Compliance Matters
NYDFS enforces Part 500 aggressively, with consent orders and fines up to USD 30 million, and the annual certification signed by the CEO and CISO creates personal accountability. Penetration testing and vulnerability assessments are explicit, recurring obligations under Section 500.5.
Because web, mobile and API applications are a primary attack surface for financial institutions, demonstrable testing is one of the most direct ways to meet Part 500 and avoid enforcement.
