Security Architecture¶
Definition¶
Security architecture for eKYC systems — protecting biometric data, preventing unauthorized access, and meeting compliance requirements.
Security Layers¶
| Layer | Controls |
|---|---|
| Network | VPC isolation, WAF, DDoS protection, private subnets for processing |
| Application | API authentication (OAuth2/JWT), rate limiting, input validation |
| Data | Encryption at rest (AES-256) and in transit (TLS 1.3), key management |
| Compute | Container security, image scanning, runtime protection |
| Access | RBAC, MFA for admin, principle of least privilege |
| Monitoring | SIEM, intrusion detection, anomaly alerting |
| Client | SDK integrity, certificate pinning, anti-tampering |
Threat Model for eKYC¶
| Threat | Target | Mitigation |
|---|---|---|
| Data breach | Biometric database | Encryption, access control, template protection |
| API abuse | eKYC API | Rate limiting, authentication, anomaly detection |
| Man-in-the-middle | Data in transit | TLS 1.3, certificate pinning |
| Insider threat | Admin access | RBAC, audit logging, MFA |
| Injection attack | Camera/SDK bypass | SDK integrity checks, server-side validation |
Key Takeaways¶
Summary
- eKYC processes the most sensitive personal data (biometrics) — security is paramount
- Defense in depth — every layer has independent security controls
- Encryption everywhere — at rest (AES-256), in transit (TLS 1.3), in processing (secure enclaves optional)
- Audit logging of all access to biometric data is both a security and compliance requirement
