# Security Testing Implementation Summary

## Overview
Implemented comprehensive security testing infrastructure with defense-in-depth analysis and automated penetration testing capabilities.

## Features Implemented

### 1. Backend API (`/backend/routes/security-testing.js`)

#### Defense-in-Depth Analyzer
- **Endpoint**: `GET /api/security-testing/defense-layers`
- **Purpose**: Analyzes all 4 security layers with automated scoring (0-100 per layer)
- **Layers Analyzed**:
  1. **Network Level**: Docker isolation, rate limiting (5 limiters), CORS validation, firewall rules
  2. **Server Level**: Node.js version check, Helmet headers (CSP, HSTS), dependency vulnerabilities via npm audit
  3. **Application Level**: JWT authentication, input validation, RBAC implementation, session management, audit logging
  4. **Data Level**: bcrypt password hashing, encryption modules, SQL injection prevention, database permissions, 2FA availability

#### Penetration Testing Module
- **Endpoint**: `POST /api/security-testing/penetration-test`
- **Purpose**: Runs automated security tests simulating attacks
- **Test Types**:
  1. **Authentication Tests**: JWT bypass attempts, weak token validation, session hijacking
  2. **SQL Injection Tests**: Query parameter injection, union attacks, blind SQL injection
  3. **XSS Tests**: Script injection in inputs, stored XSS, reflected XSS
  4. **CSRF Tests**: Token validation, referer checking, same-site cookie validation
  5. **Rate Limiting Tests**: Brute force attempt detection, rate limit enforcement

#### Network Security Monitoring
- **Endpoint**: `GET /api/security-testing/network-stats`
- **Purpose**: Real-time network security statistics
- **Metrics Tracked**:
  - Active connections count
  - Blocked requests (last 24h)
  - Failed login attempts (last 24h)
  - Total requests (last 24h)
  - Rate limited requests (last 24h)

#### Test History
- **Endpoint**: `GET /api/security-testing/test-history`
- **Purpose**: Audit trail of all penetration tests executed
- **Database Table**: `security_tests`
  - Test type, name, status, severity
  - Findings (JSON), recommendations (JSON)
  - Execution timestamps, duration, executed by user

### 2. Frontend Dashboard (`/frontend/src/components/SecurityTestingDashboard.jsx`)

#### Features
- **4 Tabs**: Defense-in-Depth, Penetration Testing, Test History, Network Security
- **Overall Security Score**: A-F grading with visual score display
- **Layer Visualization**: Circular progress for each layer with color-coded scores
- **Test Runner**: Checkbox selection for penetration tests with execution status
- **Results Display**: Accordion-based detailed findings and recommendations
- **Network Stats**: Real-time monitoring dashboard with connection/block metrics
- **Test History Table**: Filterable test execution history with all details
- **Theme Support**: Full light/dark mode compatibility
- **Localization**: Complete EN/RO translations

#### User Interface

### 3. Integration Points

#### Backend Routes
```javascript
// backend/server.js
app.use('/api/security-testing', require('./routes/security-testing'));
```

#### Frontend Routes
```javascript
// frontend/src/App.jsx
<Route path="security/testing" element={<SecurityTestingDashboard />} />
```

#### Security Dashboard Link
```javascript
// frontend/src/pages/SecurityDashboard.jsx
<Button onClick={() => navigate('/security/testing')}>

</Button>
```

### 4. Translations Added

#### English (`en.json`)

- defenseInDepth, networkLayer, serverLayer, applicationLayer, dataLayer
- penetrationTesting, penetrationTestingInfo
- authenticationTests, sqlInjectionTests, xssTests, csrfTests, rateLimitTests
- runPenetrationTests, runningTests, testsCompleted, testsFailed
- findings, testHistory, networkSecurity, activeConnections, blockedRequests
- rateLimitingStats, totalRequests, rateLimited

#### Romanian (`ro.json`)
- Full translations matching all English keys
- Localized for Romanian users

## Security Features

### Authentication & Authorization
- All endpoints require JWT authentication
- RBAC enforcement with `requirePermission('security.view_audit')`
- Admin bypass for userId === 1
- Rate limiting on all endpoints (modifyLimiter, readLimiter)

### Defense-in-Depth Scoring Algorithm
```javascript
Score = (Pass Count / Total Checks) * 100

Grade Assignment:
- 90-100: A (Excellent)
- 80-89:  B (Good)
- 70-79:  C (Fair)
- 60-69:  D (Poor)
- <60:    F (Critical)
```

### Penetration Test Safety
- All tests are read-only and non-destructive
- Tests validate security controls without exploitation
- Findings categorized by severity: critical, high, medium, low
- Recommendations provided for all failed tests

## Database Schema

### security_tests Table
```sql
CREATE TABLE IF NOT EXISTS security_tests (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  test_type TEXT NOT NULL,          -- 'defense-in-depth' or 'penetration'
  test_name TEXT NOT NULL,          -- Name of specific test
  status TEXT NOT NULL,             -- 'pass', 'fail', 'warn'
  severity TEXT,                    -- 'critical', 'high', 'medium', 'low'
  findings TEXT,                    -- JSON array of findings
  recommendations TEXT,             -- JSON array of recommendations
  started_at DATETIME DEFAULT CURRENT_TIMESTAMP,
  completed_at DATETIME,
  duration_ms INTEGER,
  executed_by INTEGER,              -- User ID
  FOREIGN KEY (executed_by) REFERENCES users(id)
);
```

## Access Control
