Medical-Grade Security Implementation

Overview

Mind Measure has implemented comprehensive medical-grade security features to ensure HIPAA, GDPR, and SOC2 compliance. This implementation provides enterprise-level security for healthcare applications handling Protected Health Information (PHI).

Security Architecture

Multi-Factor Authentication (MFA)

  • AWS Cognito Integration: Leverages AWS Cognito User Pools with MFA enabled
  • SMS-based MFA: Primary authentication method using phone verification
  • TOTP Support: Time-based One-Time Password using authenticator apps (Google Authenticator, Authy)
  • Strong Password Policies: Minimum 12 characters with complexity requirements

Comprehensive Audit Logging

  • Tamper-proof Logs: All PHI access and modifications are logged immutably
  • Real-time Monitoring: Critical security events trigger immediate alerts
  • Compliance Reporting: Automated generation of HIPAA, GDPR, and SOC2 reports
  • Risk-based Classification: Events categorized as LOW, MEDIUM, HIGH, or CRITICAL

Field-Level Encryption

  • AES-256-GCM Encryption: Military-grade encryption for sensitive data fields
  • Context-aware Encryption: Additional authenticated data (AAD) for enhanced security
  • Key Management: Secure key rotation and management capabilities
  • PHI Field Detection: Automatic identification and encryption of PHI data

Implementation Details

MFA Service Configuration

// Initialize MFA Service
const mfaService = createMFAService();
 
// Sign up with MFA requirement
const result = await mfaService.signUpWithMFA(
  email, 
  password, 
  phoneNumber
);
 
// Handle MFA challenge
const authResult = await mfaService.respondToMFAChallenge(
  challengeName,
  session,
  mfaCode,
  email
);

Audit Logging Usage

// Initialize Audit Logger
const auditLogger = createAuditLogger(databaseService);
 
// Log PHI access
await auditLogger.logPHIAccess(
  'PHI_VIEW',
  userId,
  userEmail,
  resourceId
);
 
// Log authentication events
await auditLogger.logAuth(
  'LOGIN_SUCCESS',
  userId,
  userEmail,
  ipAddress
);

PHI Encryption Implementation

// Initialize PHI Encryption
const phiEncryption = createPHIEncryption();
 
// Encrypt sensitive data
const encrypted = phiEncryption.encrypt(
  sensitiveData,
  { userId, timestamp }
);
 
// Decrypt when needed
const decrypted = phiEncryption.decrypt(
  encryptedData,
  keyId,
  context
);

Database Schema

Audit Logs Table

The audit logs table provides comprehensive tracking of all system activities:

CREATE TABLE audit_logs (
    id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
    timestamp TIMESTAMPTZ NOT NULL DEFAULT NOW(),
    user_id VARCHAR(255) NOT NULL,
    user_email VARCHAR(255),
    action VARCHAR(100) NOT NULL,
    resource VARCHAR(100) NOT NULL,
    resource_id VARCHAR(255),
    details JSONB,
    ip_address INET,
    user_agent TEXT,
    session_id VARCHAR(255),
    success BOOLEAN NOT NULL DEFAULT true,
    error_message TEXT,
    risk_level VARCHAR(20) NOT NULL,
    compliance_flags TEXT[]
);
