+      });
+    }
+  } catch (error) {
+    console.error('Error loading achievements:', error);
+  }
+}
+```
+
+### Beispiel: Statistiken anzeigen

+## 📊 Statistiken
+
+### Datenbank-Größe
+```sql
+-- Gesamtgröße der Datenbank
+SELECT pg_size_pretty(pg_database_size('ninjaserver')) as database_size;
+
+-- Größe der einzelnen Tabellen
+SELECT 
+    schemaname,
+    tablename,
+    pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) as size
+FROM pg_tables 
+WHERE schemaname = 'public'
+ORDER BY pg_total_relation_size(schemaname||'.'||tablename) DESC;
+```
+
+### Tabellen-Statistiken
+```sql
+-- Anzahl der Datensätze pro Tabelle
+SELECT 
+    'players' as table_name, COUNT(*) as record_count FROM players
+UNION ALL
+SELECT 'locations', COUNT(*) FROM locations
+UNION ALL
+SELECT 'times', COUNT(*) FROM times
+UNION ALL
+SELECT 'achievements', COUNT(*) FROM achievements

+UNION ALL
+SELECT 'adminusers', COUNT(*) FROM adminusers
+UNION ALL
+SELECT 'api_tokens', COUNT(*) FROM api_tokens
+UNION ALL
+SELECT 'page_views', COUNT(*) FROM page_views;
+```
+
+### Performance-Statistiken
+```sql
+-- Langsamste Queries
+SELECT 
+    query,
+    calls,
+    total_time,
+    mean_time,
+    rows
+FROM pg_stat_statements 
+ORDER BY mean_time DESC 
+LIMIT 10;

+    schemaname,
+    tablename,
+    indexname,
+    idx_scan,
+    idx_tup_read,
+    idx_tup_fetch
+FROM pg_stat_user_indexes 
+ORDER BY idx_scan DESC;
+```
+
+## 🛠️ Wartung
+
+### Backup
+```bash
+# Vollständiges Backup
+pg_dump -h localhost -U username -d ninjaserver > ninjaserver_backup.sql
+
+# Nur Schema
+pg_dump -h localhost -U username -d ninjaserver --schema-only > schema_backup.sql
+
+# Nur Daten
+pg_dump -h localhost -U username -d ninjaserver --data-only > data_backup.sql
+
+# Komprimiertes Backup
+pg_dump -h localhost -U username -d ninjaserver | gzip > ninjaserver_backup.sql.gz
+```
+
+### Wiederherstellung
+```bash
+# Vollständige Wiederherstellung
+psql -h localhost -U username -d ninjaserver < ninjaserver_backup.sql
+
+# Schema wiederherstellen
+psql -h localhost -U username -d ninjaserver < schema_backup.sql
+
+# Daten wiederherstellen
+psql -h localhost -U username -d ninjaserver < data_backup.sql
+```
+
+### Wartungsaufgaben
+```sql
+-- Tabellen analysieren
+ANALYZE;
+
+-- Indizes neu aufbauen
+REINDEX DATABASE ninjaserver;
+
+-- Vakuum durchführen
+VACUUM ANALYZE;
+
+-- Speicher freigeben
+VACUUM FULL;
+```
+
+### Monitoring
+```sql
+-- Aktive Verbindungen
+SELECT 
+    pid,
+    usename,
+    application_name,
+    client_addr,
+    state,
+    query_start,
+    query
+FROM pg_stat_activity 
+WHERE state = 'active';
+
+-- Locks
+SELECT 
+    pid,
+    mode,
+    locktype,
+    relation::regclass,
+    granted
+FROM pg_locks 
+WHERE NOT granted;
+
+-- Wartende Queries
+SELECT 
+    pid,
+    usename,
+    application_name,
+    state,
+    query_start,
+    query
+FROM pg_stat_activity 
+WHERE state = 'waiting';
+```
+
+### Sicherheit
+```sql
+-- Benutzerrechte prüfen
+SELECT 
+    usename,
+    usesuper,
+    usecreatedb,
+    usebypassrls
+FROM pg_user;
+
+-- Tabellenrechte prüfen
+SELECT 
+    schemaname,

+// API-Key Authentifizierung
+const headers = {
+  'Authorization': 'Bearer YOUR_API_KEY',
+  'Content-Type': 'application/json'
+};
+
+// Session-basierte Authentifizierung
+const session = await authenticateUser(username, password);
+```
+
+### API-Client Beispiel
+```javascript
+class NinjaParkourAPI {
+  constructor(apiKey, baseURL = 'http://localhost:3000') {
+    this.apiKey = apiKey;
+    this.baseURL = baseURL;
+  }

+        'Content-Type': 'application/json',
+        ...options.headers
+      },
+      ...options
+    };
+
+    const response = await fetch(url, config);
+    return response.json();
+  }
+
+  // Spieler erstellen
+  async createPlayer(playerData) {
+    return this.request('/api/v1/public/players', {

+Fügen Sie den Key in den Authorization Header ein:
+```http
+Authorization: Bearer YOUR_API_KEY_HERE
+```
+
+### Wie lange sind API-Keys gültig?
+API-Keys sind standardmäßig unbegrenzt gültig, können aber mit einem Ablaufdatum versehen werden.
+
+### Kann ich mehrere API-Keys haben?
+Ja, Sie können beliebig viele API-Keys erstellen, z.B. für verschiedene Anwendungen oder Benutzer.
+

+  -H "Authorization: Bearer YOUR_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"player_id": "AA:BB:CC:DD", "location_id": "Standort-Name", "recorded_time": "01:23.456"}'
+```
+
+### Welches Zeitformat wird verwendet?
+Zeiten werden im Format `MM:SS.mmm` gespeichert:
+- Minuten:Sekunden.Millisekunden
+- Beispiel: `01:23.456` = 1 Minute, 23 Sekunden, 456 Millisekunden
+
+### Was ist eine gültige Zeit?
+- **Minimum:** 30 Sekunden
+- **Maximum:** 10 Minuten
+- **Schwelle:** Konfigurierbar pro Standort (Standard: 120 Sekunden)
+

+  -d '{"name": "München", "latitude": 48.1351, "longitude": 11.5820}'
+```
+
+### Wie ändere ich die Zeit-Schwelle eines Standorts?
+```bash
+curl -X PUT http://localhost:3000/api/v1/private/locations/{id}/threshold \
+  -H "Authorization: Bearer YOUR_API_KEY" \
+  -H "Content-Type: application/json" \

+
+## 🛡️ Sicherheitsübersicht
+
+### Sicherheitsprinzipien
+- **Defense in Depth** - Mehrschichtige Sicherheit
+- **Least Privilege** - Minimale Berechtigungen
+- **Zero Trust** - Kein Vertrauen ohne Verifikation
+- **Security by Design** - Sicherheit von Anfang an
+
+### Bedrohungsmodell
+- **Externe Angriffe** - Unbefugter Zugriff von außen
+- **Interne Bedrohungen** - Missbrauch durch autorisierte Benutzer
+- **Datenlecks** - Unbefugte Offenlegung von Daten
+- **Service-Ausfälle** - Verfügbarkeitsprobleme
+
+## 🔐 Authentifizierung
+
+### Passwort-Sicherheit
+```javascript
+// Passwort-Hashing mit bcrypt
+const bcrypt = require('bcrypt');
+
+// Passwort hashen
+const saltRounds = 12;
+const hashedPassword = await bcrypt.hash(password, saltRounds);
+
+// Passwort verifizieren
+const isValid = await bcrypt.compare(password, hashedPassword);
+```
+
+### Passwort-Richtlinien
+- **Mindestlänge:** 12 Zeichen
+- **Komplexität:** Groß-/Kleinbuchstaben, Zahlen, Sonderzeichen
+- **Keine Wörterbuchwörter**
+- **Regelmäßige Rotation** (alle 90 Tage)
+
+### Multi-Faktor-Authentifizierung (MFA)
+```javascript
+// TOTP-Implementierung
+const speakeasy = require('speakeasy');
+
+// Secret generieren
+const secret = speakeasy.generateSecret({
+  name: 'Ninja Parkour',
+  account: 'admin@example.com'
+});
+
+// Token verifizieren
+const verified = speakeasy.totp.verify({
+  secret: secret.base32,
+  encoding: 'base32',
+  token: userToken,
+  window: 2
+});
+```
+
+### Session-Management
+```javascript
+// Sichere Session-Konfiguration
+app.use(session({
+  secret: process.env.SESSION_SECRET,
+  resave: false,
+  saveUninitialized: false,
+  cookie: {
+    secure: process.env.NODE_ENV === 'production',
+    httpOnly: true,
+    maxAge: 24 * 60 * 60 * 1000, // 24 Stunden
+    sameSite: 'strict'
+  }
+}));
+```
+
+## 🔑 Autorisierung
+
+### Rollenbasierte Zugriffskontrolle (RBAC)
+```javascript
+// Rollen definieren
+const ROLES = {
+  ADMIN: 'admin',
+  MODERATOR: 'moderator',
+  USER: 'user',
+  GUEST: 'guest'
+};
+
+// Berechtigungen definieren
+const PERMISSIONS = {
+  READ_PLAYERS: 'read:players',
+  WRITE_PLAYERS: 'write:players',
+  DELETE_PLAYERS: 'delete:players',
+  READ_TIMES: 'read:times',
+  WRITE_TIMES: 'write:times',
+  ADMIN_ACCESS: 'admin:access'
+};
+
+// Rollen-Berechtigungen
+const rolePermissions = {
+  [ROLES.ADMIN]: Object.values(PERMISSIONS),
+  [ROLES.MODERATOR]: [
+    PERMISSIONS.READ_PLAYERS,
+    PERMISSIONS.WRITE_PLAYERS,
+    PERMISSIONS.READ_TIMES,
+    PERMISSIONS.WRITE_TIMES
+  ],
+  [ROLES.USER]: [
+    PERMISSIONS.READ_PLAYERS,
+    PERMISSIONS.READ_TIMES
+  ]
+};
+```
+
+### API-Key-Management
+```javascript
+// API-Key generieren
+const generateAPIKey = () => {
+  return crypto.randomBytes(32).toString('hex');
+};
+
+// API-Key validieren
+const validateAPIKey = async (apiKey) => {
+  const token = await db.query(
+    'SELECT * FROM api_tokens WHERE token = $1 AND is_active = true',
+    [apiKey]
+  );
+  return token.rows.length > 0;
+};
+
+// Berechtigungen prüfen
+const checkPermission = (userRole, requiredPermission) => {
+  const userPermissions = rolePermissions[userRole] || [];
+  return userPermissions.includes(requiredPermission);
+};
+```
+
+### Middleware für Autorisierung
+```javascript
+// Authentifizierung prüfen
+const requireAuth = (req, res, next) => {
+  if (!req.session || !req.session.userId) {
+    return res.status(401).json({ error: 'Nicht authentifiziert' });
+  }
+  next();
+};
+
+// Rolle prüfen
+const requireRole = (role) => {
+  return (req, res, next) => {
+    if (req.session.role !== role) {
+      return res.status(403).json({ error: 'Keine Berechtigung' });
+    }
+    next();
+  };
+};
+
+// Berechtigung prüfen
+const requirePermission = (permission) => {
+  return (req, res, next) => {
+    const userRole = req.session.role;
+    if (!checkPermission(userRole, permission)) {
+      return res.status(403).json({ error: 'Keine Berechtigung' });
+    }
+    next();
+  };
+};
+```
+
+## 🛡️ Datenverschlüsselung
+
+### Verschlüsselung im Ruhezustand
+```javascript
+// Datenbank-Verschlüsselung
+const crypto = require('crypto');
+
+// Verschlüsselung
+const encrypt = (text, key) => {
+  const iv = crypto.randomBytes(16);
+  const cipher = crypto.createCipher('aes-256-cbc', key);
+  let encrypted = cipher.update(text, 'utf8', 'hex');
+  encrypted += cipher.final('hex');
+  return iv.toString('hex') + ':' + encrypted;
+};
+
+// Entschlüsselung
+const decrypt = (text, key) => {
+  const textParts = text.split(':');
+  const iv = Buffer.from(textParts.shift(), 'hex');
+  const encryptedText = textParts.join(':');
+  const decipher = crypto.createDecipher('aes-256-cbc', key);
+  let decrypted = decipher.update(encryptedText, 'hex', 'utf8');
+  decrypted += decipher.final('utf8');
+  return decrypted;
+};
+```
+
+### Verschlüsselung in Bewegung
+```javascript
+// HTTPS-Konfiguration
+const https = require('https');
+const fs = require('fs');
+
+const options = {
+  key: fs.readFileSync('private-key.pem'),
+  cert: fs.readFileSync('certificate.pem'),
+  ciphers: [
+    'ECDHE-RSA-AES256-GCM-SHA384',
+    'ECDHE-RSA-AES128-GCM-SHA256',
+    'ECDHE-RSA-AES256-SHA384',
+    'ECDHE-RSA-AES128-SHA256'
+  ].join(':'),
+  honorCipherOrder: true
+};
+
+https.createServer(options, app).listen(443);
+```
+
+### Passwort-Verschlüsselung
+```javascript
+// Starke Passwort-Generierung
+const generatePassword = (length = 16) => {
+  const charset = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*';
+  let password = '';
+  for (let i = 0; i < length; i++) {
+    password += charset.charAt(Math.floor(Math.random() * charset.length));
+  }
+  return password;
+};
+
+// Passwort-Stärke prüfen
+const validatePassword = (password) => {
+  const minLength = 12;
+  const hasUpperCase = /[A-Z]/.test(password);
+  const hasLowerCase = /[a-z]/.test(password);
+  const hasNumbers = /\d/.test(password);
+  const hasSpecialChar = /[!@#$%^&*(),.?":{}|<>]/.test(password);
+  
+  return password.length >= minLength && 
+         hasUpperCase && 
+         hasLowerCase && 
+         hasNumbers && 
+         hasSpecialChar;
+};
+```
+
+## 🌐 Netzwerksicherheit
+
+### Firewall-Konfiguration
+```bash
+# UFW-Firewall (Ubuntu)
+sudo ufw enable
+sudo ufw default deny incoming
+sudo ufw default allow outgoing
+
+# Erlaubte Ports
+sudo ufw allow 22/tcp    # SSH
+sudo ufw allow 80/tcp    # HTTP
+sudo ufw allow 443/tcp   # HTTPS
+sudo ufw allow 3000/tcp  # App (nur intern)
+
+# Rate Limiting
+sudo ufw limit ssh
+```
+
+### DDoS-Schutz
+```javascript
+// Rate Limiting
+const rateLimit = require('express-rate-limit');
+
+const limiter = rateLimit({
+  windowMs: 15 * 60 * 1000, // 15 Minuten
+  max: 100, // Max 100 Requests pro IP
+  message: 'Zu viele Anfragen von dieser IP',
+  standardHeaders: true,
+  legacyHeaders: false
+});
+
+app.use('/api/', limiter);
+
+// Strikte Rate Limits für sensible Endpoints
+const strictLimiter = rateLimit({
+  windowMs: 15 * 60 * 1000,
+  max: 5,
+  message: 'Zu viele Login-Versuche'
+});
+
+app.use('/api/login', strictLimiter);
+```
+
+### CORS-Konfiguration
+```javascript
+// Sichere CORS-Einstellungen
+const cors = require('cors');
+
+const corsOptions = {
+  origin: (origin, callback) => {
+    const allowedOrigins = [
+      'https://ninja.reptilfpv.de',
+      'https://www.ninja.reptilfpv.de'
+    ];
+    
+    if (!origin || allowedOrigins.includes(origin)) {
+      callback(null, true);
+    } else {
+      callback(new Error('Nicht erlaubt durch CORS'));
+    }
+  },
+  credentials: true,
+  optionsSuccessStatus: 200
+};
+
+app.use(cors(corsOptions));
+```
+
+### SSL/TLS-Konfiguration
+```javascript
+// SSL-Redirect
+app.use((req, res, next) => {
+  if (req.header('x-forwarded-proto') !== 'https') {
+    res.redirect(`https://${req.header('host')}${req.url}`);
+  } else {
+    next();
+  }
+});
+
+// Security Headers
+const helmet = require('helmet');
+
+app.use(helmet({
+  contentSecurityPolicy: {
+    directives: {
+      defaultSrc: ["'self'"],
+      styleSrc: ["'self'", "'unsafe-inline'"],
