# TransTrack - Technical Due Diligence Report

**Product:** TransTrack v1.0.0
**Category:** HIPAA/FDA/AATB-Compliant Transplant Waitlist Management System
**Platform:** Offline-first desktop application (Windows, macOS, Linux)
**Architecture:** Electron + React (Vite) + SQLite (SQLCipher)
**Date:** March 2026

---

## 1. Executive Summary

TransTrack is an offline-first, HIPAA-compliant desktop application designed for organ transplant centers to manage patient waitlists, donor matching, and regulatory compliance. The system operates entirely on-premises with no external network dependencies, ensuring complete data sovereignty for healthcare organizations.

The application employs defense-in-depth security: AES-256 database encryption (SQLCipher), OS-native keychain key protection, role-based access control (RBAC), immutable audit trails, session binding, rate limiting, and content security policies. It has been designed and validated against HIPAA Technical Safeguards, FDA 21 CFR Part 11, and AATB standards.

---

## 2. Architecture Overview

### Technology Stack

| Layer | Technology | Purpose |
|---|---|---|
| Runtime | Electron 35.x | Cross-platform desktop framework |
| Frontend | React 19, Vite 6, TailwindCSS | Modern component-based UI |
| Backend | Node.js (Electron main process) | Business logic, IPC handlers |
| Database | SQLite via better-sqlite3-multiple-ciphers | Encrypted local storage |
| Encryption | SQLCipher (AES-256-CBC, PBKDF2-HMAC-SHA512) | At-rest data encryption |

### Codebase Metrics

| Metric | Value |
|---|---|
| Frontend source files (JSX/JS/CSS) | 116 |
| Backend source files (CJS) | 39 |
| Test files | 5 |
| Database tables | 22 |
| Total dependencies (production) | 63 |
| Total dependencies (development) | 21 |
| Automated tests | 87 |
| Documentation files | 17 |

### Data Flow

```
User Interface (React/Renderer)
|
| contextBridge (IPC, context-isolated)
|
Preload Script (whitelisted API surface)
|
| ipcMain.handle (rate-limited, session-validated)
|
IPC Handlers (RBAC-enforced, audit-logged)
|
| Parameterized queries only
|
SQLCipher Database (AES-256 encrypted at rest)
```

All renderer-to-main communication passes through a secure IPC bridge with context isolation. No direct `nodeIntegration` is exposed to the renderer. Every IPC handler validates the session, checks rate limits, enforces RBAC permissions, and logs the operation to an immutable audit trail.

---

## 3. Security Controls

### 3.1 Encryption

| Control | Implementation |
|---|---|
| At-rest encryption | SQLCipher AES-256-CBC with 256,000 PBKDF2 iterations |
| Key storage | OS-native keychain via Electron safeStorage API |
| Key migration | Transparent upgrade from file-based to keychain-protected keys |
| Key rotation | `PRAGMA rekey` support with backup/restore workflow |
| Fallback | File-based key with 0o600 permissions if OS keychain unavailable |

### 3.2 Authentication & Session Management

| Control | Implementation |
|---|---|
| Password hashing | bcrypt with configurable salt rounds |
| Password policy | Minimum 12 characters, uppercase, lowercase, digit, special character |
| Account lockout | 5 failed attempts triggers 15-minute lockout |
| Session expiration | Configurable timeout with automatic invalidation |
| Session binding | Bound to Electron WebContents ID to prevent session riding |
| First-login enforcement | Default admin must change password on first login |

### 3.3 Access Control

| Control | Implementation |
|---|---|
| Model | Role-Based Access Control (RBAC) |
| Roles | Admin, Coordinator, Surgeon, Viewer (and custom) |
| Enforcement point | Server-side IPC handlers (cannot be bypassed from renderer) |
| Entity-level permissions | All CRUD operations check `hasPermission()` before execution |
| Organization isolation | Multi-tenant with strict `org_id` scoping on all queries |
| PHI access justification | Required justification logging for sensitive data access |

### 3.4 Network & Transport Security

| Control | Implementation |
|---|---|
| Network exposure | Zero — fully offline, no external API calls in production |
| Content Security Policy | Strict CSP headers on all renderer windows |
| Navigation restrictions | External navigation and popup creation blocked |
| DevTools | Disabled in packaged production builds |
| Web security | `webSecurity: true`, `contextIsolation: true`, `nodeIntegration: false` |

### 3.5 Infrastructure Security

| Control | Implementation |
|---|---|
| Rate limiting | All IPC handlers rate-limited (global middleware) |
| Input validation | Parameterized SQL queries, entity name whitelist, ReDoS-safe patterns |
| Structured logging | JSON log files with rotation (10 MB, 5 files) |
| Crash reporting | Electron crashReporter with local-only dump storage |
| Dependency management | All versions pinned (no caret ranges), `npm ci` in CI |

---

| Authentication (§164.312(d)) | Compliant | bcrypt password hashing, account lockout, session management |

### 4.2 FDA 21 CFR Part 11

| Requirement | Status | Implementation |
|---|---|---|
| Electronic Signatures | Compliant | Password-based authentication for all operations |

## 10. Known Limitations & Roadmap

### 10.1 Pre-Sale Requirements

These items should be completed before first customer delivery:

| Item | Status | Effort |
|---|---|---|
| Code signing certificate (Windows EV + Apple Developer) | Pending | Procurement (~$400-700/year) |
| macOS notarization | Configured, pending Apple Developer enrollment | Configuration only |
| Auto-update release infrastructure | Configured, pending first GitHub Release | Low |
| HIPAA Business Associate Agreement (template) | Guidance documented | Legal review |

### 10.2 Future Enhancements

| Feature | Priority | Description |
|---|---|---|
| Multi-language support (i18n) | Medium | Localization for international markets |
| Biometric authentication | Medium | Windows Hello / Touch ID integration |
| Cloud sync (optional) | Low | Encrypted cloud backup for multi-site deployments |
| Advanced analytics dashboard | Medium | Statistical analysis and trend visualization |
| HL7 v2 integration | Low | Legacy EHR system interoperability |

---

## 11. Risk Assessment

| Risk | Severity | Mitigation |
|---|---|---|
| Local malware accessing database | Medium | SQLCipher encryption + OS keychain key protection |
| Lost encryption key | Medium | Key backup file, documented recovery procedures |
| Unauthorized data access | Low | RBAC + audit logging + org isolation |
| Supply chain attack via dependencies | Low | Pinned versions, `npm audit` in CI, SBOM generation |
| Data loss | Low | Single-file database, standard backup procedures |
| License circumvention | Low | HMAC integrity seal, machine binding, server-side enforcement |

---

## 12. Summary

TransTrack v1.0.0 implements enterprise-grade security controls appropriate for HIPAA-regulated healthcare environments:

- **87 automated tests** covering security, business logic, and compliance
- **AES-256 encryption** with OS-keychain key protection
- **Role-based access control** enforced at the IPC handler level
- **Immutable audit trails** meeting HIPAA and FDA requirements
- **Zero network exposure** — fully offline architecture eliminates an entire class of attacks
- **Multi-tenant isolation** with strict organization scoping
- **CI/CD pipeline** with blocking security checks and SBOM generation
- **17 compliance and operational documents** maintained

The codebase is production-ready for enterprise healthcare deployment. The remaining pre-sale items (code signing certificate, Apple Developer enrollment) are procurement tasks, not engineering work.
