Enterprise Security Architecture
Multi-Layer Security Model
The platform implements a comprehensive 5-layer security architecture designed for healthcare data protection, combining authentication, authorization, rate limiting, bot protection, and monitoring to safeguard sensitive client information.
🔐 Authentication & Authorization
Industry-standard authentication with NextAuth.js providing secure session management, role-based access control, and comprehensive password security measures.
Core Security Features
- ✓NextAuth.js Integration: Industry-standard OAuth provider with credentials authentication
- ✓Bcrypt Hashing: 12-round salted password hashing for secure credential storage
- ✓JWT Sessions: 24-hour expiry tokens with automatic refresh and secure storage
- ✓Role-Based Access: Owner and Admin roles with granular permission control
- ✓Server-Side Validation: Every protected route verifies session authentication
🛡️ Progressive Rate Limiting & IP Protection
Intelligent rate limiting system with progressive escalation to prevent brute-force attacks while maintaining usability for legitimate users.
Rate Limit Tiers
- Tier 1: 5 failed attempts = 15-minute cooldown
- Tier 2: 10 total attempts = 1-hour IP ban
- Whitelist: Admin-configurable trusted IPs
- Auto-Cleanup: Expired limits cleared automatically
IP Management
- • Real-time tracking of login attempts
- • Manual IP blocking / unblocking
- • Permanent whitelist configuration
- • Security dashboard monitoring
Math-Based CAPTCHA
Lightweight bot protection using simple arithmetic questions (addition/subtraction). No external dependencies or user tracking required. Tokens expire after 5 minutes.
🔑 Password Management & Recovery
Secure password reset workflow with token-based verification, time-limited access, and encrypted email delivery for account recovery.
Reset Flow Security
- •Crypto-Secure Tokens: 32-byte random tokens generated with Node.js crypto module
- •Time-Limited Access: Reset links expire after 1 hour for security
- •One-Time Use: Tokens are cleared after successful password reset
- •Email Verification: Reset links sent only to registered email addresses
- •Fallback Logging: Console output when SMTP not configured (dev mode)
🛠️ Additional Security Measures
Application Security
- • SQL Injection: Prisma parameterized queries
- • XSS Prevention: React automatic escaping + CSP
- • CSRF Protection: NextAuth built-in tokens
- • Secure Headers: Next.js security configuration
- • HTTPS Only: SSL/TLS enforced in production
Data Protection
- • Environment Variables: Secrets never committed
- • Database Backups: Built-in backup/restore scripts
- • GDPR Compliance: User data protection measures
- • Audit Logging: Security event tracking
- • Session Security: HttpOnly cookies
📊 Security Monitoring Dashboard
Real-time security monitoring interface providing visibility into authentication attempts, blocked IPs, rate limit status, and system security events.
Dashboard Capabilities
- ✓Blocked IP Monitoring: View all currently blocked addresses with ban duration
- ✓Login Attempt Tracking: Real-time activity feed with attempt counts per IP
- ✓Manual IP Management: Pre-emptive blocking and whitelist configuration
- ✓Rate Limit Statistics: See which IPs are approaching thresholds
- ✓Auto-Refresh: Dashboard updates every 30 seconds for live monitoring
