Fintech Security & Compliance: SOC 2, PCI-DSS, and Data Encryption

Security isn't a feature in fintech; it's the foundation. A single breach can destroy a company. Here is our blueprint for securing financial applications.

Data Encryption (At Rest and In Transit)

• In Transit: TLS 1.3 is mandatory. Implement HSTS to prevent downgrade attacks.
• At Rest: Use AES-256 for all databases. PII (Personally Identifiable Information) should be encrypted at the application layer before hitting the database (Field-Level Encryption).
• Key Management: Use AWS KMS or HashiCorp Vault. Never hardcode keys.

PCI-DSS Compliance

If you handle credit cards, you need PCI compliance. The easiest way to achieve this is to not handle credit cards directly. Use Stripe Elements or Braintree Drop-in UI. This keeps your servers out of the PCI scope (SAQ-A).

SOC 2 Type II

Enterprise clients will require a SOC 2 audit. This involves: - Infrastructure as Code (Terraform) for reproducible environments - Audit logging for all administrative actions - Multi-Factor Authentication (MFA) everywhere - Background checks for all employees with production access - Annual penetration testing by a third-party firm

API Security

• Implement OAuth 2.0 / OIDC for authentication.
• Use short-lived JWTs (15 minutes) and refresh tokens.
• Implement strict rate limiting and WAF (Web Application Firewall) rules to block automated scraping and credential stuffing.
