Security Standards

BayanCore incorporates a Zero-Trust security model to protect sensitive enterprise data, satisfy Saudi cybersecurity standards (NCA), and prevent unauthorized access.

Authentication & Authorization​

  • Authentication (Clerk): Enterprise SSO (SAML/OIDC), MFA via SMS/Authenticator apps, automated brute-force protection
  • JWT Verification: API Gateway validates Clerk JWT signature on every request, extracting user context (user_id, role, company_id)
  • RBAC: Granular roles (Accountant, Sales Manager, HR Specialist) verified against target API path and method

PII Redaction Gateway​

All context payloads to OCI GPU inference cluster pass through the PII Redaction Gateway:

  1. Intercept: Scan payloads for PII before LLM processing
  2. Scan: Regex filters + NER models detect National IDs, Iqama numbers, phone numbers, emails, IBANs
  3. Redact: Replace with token placeholders
  4. Reconstruct: Re-inject variables after LLM response

Session Management​

  • Inactivity Timeouts: Sessions expire after 15 minutes of inactivity
  • Force Logout: Account changes in Clerk immediately invalidate Redis session cache (<60s)
  • Concurrent Limits: Max 2 active sessions per user (prevents credential sharing)

Audit Trail​

  • Append-Only: DB role restricted to INSERT only — UPDATE/DELETE programmatically blocked
  • Integrity Hashing: SHA-256 hash chain — every entry links to previous, weekly cron verifies integrity
  • Payload: Gregorian + Hijri timestamps, IP address, Clerk User ID, action, changed fields

Incident Response​

  • AI Error Detected: Immediate rollback, user notification, incident log
  • Data Breach Suspected: AI access suspended, audit review, PDPL notification
  • Model Degradation: Fallback to rule-based system, retraining triggered
