Security Best Practices

Secure Coding Guidelines

Input Validation

const { SecurityUtils } = require('@security-guidance/utils');

// Validate user input
function validateUserInput(input) {
  return SecurityUtils.validate(input, {
    type: 'string',
    maxLength: 1000,
    allowedChars: 'a-zA-Z0-9 .,!?-',
    sanitize: true,
    escape: true
  });
}

// SQL injection prevention
const query = 'SELECT * FROM users WHERE email = ?';
const result = await db.query(query, [validatedEmail]);

Authentication & Authorization

const { AuthManager } = require('@security-guidance/auth');

const auth = new AuthManager({
  jwtSecret: process.env.JWT_SECRET,
  bcryptRounds: 12,
  sessionTimeout: 3600000, // 1 hour
  maxLoginAttempts: 5,
  lockoutDuration: 900000 // 15 minutes
});

// Secure login
async function login(username, password) {
  const user = await auth.authenticate(username, password);
  if (user) {
    const token = auth.generateToken(user, { expiresIn: '1h' });
    return { success: true, token };
  }
  return { success: false, error: 'Invalid credentials' };
}

Data Encryption

const { Encryption } = require('@security-guidance/crypto');

const encryption = new Encryption({
  algorithm: 'aes-256-gcm',
  keyDerivation: 'pbkdf2',
  iterations: 100000
});

// Encrypt sensitive data
async function encryptSensitiveData(data) {
  const encrypted = await encryption.encrypt(data, process.env.ENCRYPTION_KEY);
  return encrypted;
}

// Decrypt sensitive data
async function decryptSensitiveData(encryptedData) {
  const decrypted = await encryption.decrypt(encryptedData, process.env.ENCRYPTION_KEY);
  return decrypted;
}

API Security

Rate Limiting

const { RateLimiter } = require('@security-guidance/api');

const rateLimiter = new RateLimiter({
  windowMs: 15 * 60 * 1000, // 15 minutes
  maxRequests: 100,
  skipSuccessfulRequests: false,
  skipFailedRequests: false
});

// Apply to API endpoints
app.use('/api/', rateLimiter.middleware());

CORS Configuration

const cors = require('cors');

const corsOptions = {
  origin: process.env.ALLOWED_ORIGINS?.split(',') || ['https://example.com'],
  methods: ['GET', 'POST', 'PUT', 'DELETE'],
  allowedHeaders: ['Content-Type', 'Authorization'],
  credentials: true,
  maxAge: 86400 // 24 hours
};

app.use(cors(corsOptions));

Input Sanitization

const { Sanitizer } = require('@security-guidance/sanitizer');

const sanitizer = new Sanitizer();

// Sanitize HTML input
function sanitizeHtml(input) {
  return sanitizer.html(input, {
    allowedTags: ['b', 'i', 'em', 'strong', 'p', 'br'],
    allowedAttributes: {},
    disallowedTagsMode: 'discard'
  });
}

// Sanitize SQL input
function sanitizeSql(input) {
  return sanitizer.sql(input, {
    escapeQuotes: true,
    removeComments: true,
    validateIdentifiers: true
  });
}

Compliance Monitoring

GDPR Compliance

# GDPR compliance check
security-guidance compliance gdpr --audit

# Data privacy assessment
security-guidance privacy assess --region=eu

# Generate GDPR documentation
security-guidance compliance gdpr --docs --output=./docs/gdpr

GDPR Implementation

const { GDPRCompliance } = require('@security-guidance/compliance');

const gdpr = new GDPRCompliance({
  dataController: 'Your Company',
  dataProtectionOfficer: 'dpo@company.com',
  retentionPeriod: 365, // days
  consentRequired: true
});

// Handle data subject requests
async function handleDataSubjectRequest(requestType, userId) {
  switch (requestType) {
    case 'access':
      return await gdpr.getUserData(userId);
    case 'deletion':
      return await gdpr.deleteUserData(userId);
    case 'rectification':
      return await gdpr.rectifyUserData(userId, updatedData);
    default:
      throw new Error('Invalid request type');
  }
}

SOC 2 Compliance

# SOC 2 compliance assessment
security-guidance compliance soc2 --type=type2 --audit

# Security controls validation
security-guidance controls validate --framework=soc2

# Generate SOC 2 reports
security-guidance compliance soc2 --report --format=pdf

SOC 2 Controls

const { SOC2Controls } = require('@security-guidance/compliance');

const soc2 = new SOC2Controls({
  trustServices: ['security', 'availability', 'confidentiality'],
  criteria: 'common-criteria-2017'
});

// Implement security controls
const controls = {
  accessControl: {
    implemented: true,
    evidence: ['access-logs', 'user-permissions'],
    lastReviewed: '2024-01-15'
  },
  encryption: {
    implemented: true,
    evidence: ['encryption-keys', 'cipher-suites'],
    lastReviewed: '2024-01-10'
  },
  incidentResponse: {
    implemented: true,
    evidence: ['incident-logs', 'response-procedures'],
    lastReviewed: '2024-01-12'
  }
};

await soc2.validateControls(controls);
