Phase 2: Advanced Security & Compliance

Overview

Phase 2 of Mind Measure's medical-grade security implementation introduces enterprise-level access controls, automated vulnerability management, and comprehensive backup & recovery capabilities. This phase builds upon the foundational security features from Phase 1 to provide complete healthcare compliance readiness.

New Security Features

Role-Based Access Control (RBAC)

Enterprise-grade access management with granular permissions

• 9 Predefined System Roles: From Guest (Level 0) to Super Admin (Level 100)
• 20+ Granular Permissions: Fine-grained control over resources and actions
• Resource-Level Policies: Specific access rules for individual resources
• Conditional Access: IP restrictions, time-based access, and contextual controls
• Role Hierarchies: Privilege levels prevent unauthorized escalation

System Roles

Permission Categories

• PHI Data: phi_read, phi_write, phi_delete, phi_export, phi_bulk_access
• User Management: user_read, user_write, user_delete, user_impersonate
• System Admin: system_config, system_backup, system_restore, system_monitor
• Audit & Compliance: audit_read, audit_export, compliance_report
• Role Management: role_read, role_write, role_assign, permission_grant

Vulnerability Management

Continuous security monitoring and compliance assessment

• Automated Dependency Scanning: Integration with npm audit and security databases
• Compliance Scanning: HIPAA, GDPR, SOC2, ISO27001, and NIST frameworks

Implementation Details

RBAC Service Usage

// Initialize RBAC Service
const rbacService = createRBACService(databaseService);
 
// Check user access
const accessResult = await rbacService.checkAccess(
  userId,
  'phi_data',
  'read',
  'patient-record-123',
  { ipAddress: '192.168.1.100' }
);
 
if (accessResult.allowed) {
  // Grant access
  console.log('Access granted:', accessResult.matchedPermissions);
} else {
  // Deny access
  console.log('Access denied:', accessResult.reason);
}
 
// Assign role to user
await rbacService.assignRoleToUser(
  userId,
  roleId,
  assignedBy,
  expirationDate
);
 
// Create resource-specific policy
await rbacService.createResourcePolicy({
  resourceType: 'patient_record',
  resourceId: 'patient-123',
  userId: 'doctor-456',
  permissions: ['read', 'write'],
  conditions: {
    allowedIPs: ['192.168.1.0/24'],
    allowedHours: { start: 8, end: 18 }
  }
}, createdBy);

Vulnerability Management Usage

// Initialize Vulnerability Service
const vulnService = createVulnerabilityService(databaseService);
 
// Run dependency scan
const dependencyScan = await vulnService.runDependencyScan(userId);
console.log(`Found ${dependencyScan.vulnerabilitiesFound} vulnerabilities`);
 
// Run compliance scan
const complianceScan = await vulnService.runComplianceScan(userId, 'HIPAA');
console.log(`HIPAA compliance issues: ${complianceScan.vulnerabilitiesFound}`);
 
// Generate security report
const report = await vulnService.generateSecurityReport(userId);
console.log(`Security score: ${report.compliance.hipaaCompliance}% HIPAA compliant`);
 
// Update vulnerability status
await vulnService.updateVulnerabilityStatus(
  vulnerabilityId,
  'RESOLVED',
  userId,
  'Applied security patch v2.1.3'
);

Backup & Recovery Usage

// Initialize Backup Service
const backupService = createBackupRecoveryService({
  s3BucketName: 'mindmeasure-backups',
  s3Region: 'eu-west-2',
  rdsInstanceId: 'mindmeasure-aurora',
  rdsRegion: 'eu-west-2',
  retentionDays: 30
}, databaseService);
 
// Create database snapshot
const backupResult = await backupService.createDatabaseSnapshot(
  userId,
  'Pre-deployment backup'
);
 
if (backupResult.success) {
  console.log(`Backup created: ${backupResult.backupId}`);
}
 
// List available backups
const backups = await backupService.listBackups();
console.log(`${backups.length} backups available`);
 
// Restore from snapshot
const restoreResult = await backupService.restoreFromSnapshot(
  snapshotId,
  'mindmeasure-aurora-restored',
  userId
);
