Security Procedures

This comprehensive security guide covers all security procedures, best practices, and configurations for the HostingCo system.

🔒 Security Overview

The HostingCo system implements multiple layers of security to protect user data, prevent unauthorized access, and ensure system integrity.

Security Components

Authentication & Authorization - JWT-based auth with role-based access
Data Encryption - Encryption at rest and in transit
Network Security - SSL/TLS, firewalls, and secure protocols
Input Validation - Comprehensive input sanitization and validation
Audit Logging - Complete activity tracking and monitoring
Access Control - Principle of least privilege enforcement

🔐 Authentication & Authorization

JWT Token Security

Secure Token Configuration

// backend/src/middleware/auth.ts
import jwt from 'jsonwebtoken';

const secureTokenConfig = {
  secret: process.env.JWT_SECRET, // Use strong, random secret
  expiresIn: '24h',
  algorithm: 'HS256',
  issuer: 'hostingco',
  audience: 'hostingco-users'
};

// Generate secure token
const generateToken = (user) => {
  return jwt.sign(
    { 
      id: user.id, 
      email: user.email, 
      role: user.role,
      permissions: user.permissions 
    },
    secureTokenConfig.secret,
    {
      expiresIn: secureTokenConfig.expiresIn,
      algorithm: secureTokenConfig.algorithm,
      issuer: secureTokenConfig.issuer,
      audience: secureTokenConfig.audience
    }
  );
};

Token Validation

// Verify JWT token with strict validation
const verifyToken = (token) => {
  return jwt.verify(token, process.env.JWT_SECRET, {
    algorithms: ['HS256'],
    issuer: 'hostingco',
    audience: 'hostingco-users'
  });
};

Password Security

Password Hashing

// backend/src/utils/auth.ts
import bcrypt from 'bcryptjs';

const hashPassword = async (password) => {
  const saltRounds = 12; // High salt rounds for security
  return await bcrypt.hash(password, saltRounds);
};

const verifyPassword = async (password, hash) => {
  return await bcrypt.compare(password, hash);
};

// Password strength validation
const validatePasswordStrength = (password) => {
  const minLength = 8;
  const hasUpperCase = /[A-Z]/.test(password);
  const hasLowerCase = /[a-z]/.test(password);
  const hasNumbers = /\d/.test(password);
  const hasSpecialChar = /[!@#$%^&*(),.?":{}|<>]/.test(password);

  return {
    isValid: password.length >= minLength && hasUpperCase && hasLowerCase && hasNumbers && hasSpecialChar,
    errors: [
      password.length < minLength ? 'Password must be at least 8 characters' : null,
      !hasUpperCase ? 'Password must contain uppercase letter' : null,
      !hasLowerCase ? 'Password must contain lowercase letter' : null,
      !hasNumbers ? 'Password must contain number' : null,
      !hasSpecialChar ? 'Password must contain special character' : null
    ].filter(Boolean)
  };
};

Role-Based Access Control (RBAC)

Role Definitions

// backend/src/utils/roles.ts
export const ROLES = {
  SUPER_ADMIN: 'super_admin',
  ADMIN: 'admin',
  SUPPORT: 'support',
  USER: 'user',
  READ_ONLY: 'read_only'
};

export const PERMISSIONS = {
  // User permissions
  USER_READ: 'user:read',
  USER_WRITE: 'user:write',
  USER_DELETE: 'user:delete',

  // Server permissions
  SERVER_READ: 'server:read',
  SERVER_WRITE: 'server:write',
  SERVER_DELETE: 'server:delete',
  SERVER_ADMIN: 'server:admin',

  // Billing permissions
  BILLING_READ: 'billing:read',
  BILLING_WRITE: 'billing:write',
  BILLING_DELETE: 'billing:delete',

  // Support permissions
  SUPPORT_READ: 'support:read',
  SUPPORT_WRITE: 'support:write',
  SUPPORT_DELETE: 'support:delete',

  // System permissions
  SYSTEM_READ: 'system:read',
  SYSTEM_WRITE: 'system:write',
  SYSTEM_ADMIN: 'system:admin'
};

export const ROLE_PERMISSIONS = {
  [ROLES.SUPER_ADMIN]: Object.values(PERMISSIONS),
  [ROLES.ADMIN]: [
    PERMISSIONS.USER_READ, PERMISSIONS.USER_WRITE, PERMISSIONS.USER_DELETE,
    PERMISSIONS.SERVER_READ, PERMISSIONS.SERVER_WRITE, PERMISSIONS.SERVER_DELETE,
    PERMISSIONS.BILLING_READ, PERMISSIONS.BILLING_WRITE,
    PERMISSIONS.SUPPORT_READ, PERMISSIONS.SUPPORT_WRITE,
    PERMISSIONS.SYSTEM_READ
  ],
  [ROLES.SUPPORT]: [
    PERMISSIONS.USER_READ,
    PERMISSIONS.SERVER_READ, PERMISSIONS.SERVER_WRITE,
    PERMISSIONS.SUPPORT_READ, PERMISSIONS.SUPPORT_WRITE,
    PERMISSIONS.BILLING_READ
  ],
  [ROLES.USER]: [
    PERMISSIONS.USER_READ, PERMISSIONS.USER_WRITE,
    PERMISSIONS.SERVER_READ, PERMISSIONS.SERVER_WRITE,
    PERMISSIONS.BILLING_READ,
    PERMISSIONS.SUPPORT_READ, PERMISSIONS.SUPPORT_WRITE
  ],
  [ROLES.READ_ONLY]: [
    PERMISSIONS.USER_READ,
    PERMISSIONS.SERVER_READ,
    PERMISSIONS.BILLING_READ,
    PERMISSIONS.SUPPORT_READ
  ]
};

Permission Middleware

// backend/src/middleware/permissions.ts
export const requirePermission = (permission) => {
  return (req, res, next) => {
    const user = req.user;

    if (!user) {
      return res.status(401).json({
        success: false,
        error: { code: 'AUTHENTICATION_ERROR', message: 'Authentication required' }
      });
    }

    const userPermissions = ROLE_PERMISSIONS[user.role] || [];

    if (!userPermissions.includes(permission)) {
      return res.status(403).json({
        success: false,
        error: { code: 'AUTHORIZATION_ERROR', message: 'Insufficient permissions' }
      });
    }

    next();
  };
};

// Usage example
router.get('/admin/users', 
  authenticateToken, 
  requirePermission(PERMISSIONS.USER_READ), 
  getUsers
);

Input Validation & Sanitization

Comprehensive Input Validation

// backend/src/utils/validation.ts
import Joi from 'joi';
import DOMPurify from 'isomorphic-dompurify';

// Sanitize HTML content
const sanitizeHtml = (content) => {
  return DOMPurify.sanitize(content, {
    ALLOWED_TAGS: ['p', 'br', 'strong', 'em', 'u', 'ol', 'ul', 'li'],
    ALLOWED_ATTR: ['class'],
    ALLOW_DATA_ATTR: false
  });
};

// Validation schemas
export const Schemas = {
  user: Joi.object({
    email: Joi.string().email().required(),
    password: Joi.string().min(8).pattern(/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]/).required(),
    name: Joi.string().min(2).max(100).required(),
    phone: Joi.string().pattern(/^[+]?[\d\s\-\(\)]+$/).optional(),
    company: Joi.string().max(100).optional()
  }),

  server: Joi.object({
    name: Joi.string().min(2).max(100).required(),
    plan: Joi.string().valid('basic', 'pro', 'enterprise').required(),
    location: Joi.string().valid('us-east-1', 'us-west-1', 'eu-west-1', 'asia-east-1').required()
  }),

  supportTicket: Joi.object({
    subject: Joi.string().min(5).max(200).required(),
    description: Joi.string().min(10).max(2000).required(),
    priority: Joi.string().valid('low', 'medium', 'high', 'urgent').default('medium'),
    category: Joi.string().valid('technical', 'billing', 'general').default('general')
  })
};

// Validation middleware
export const validateRequest = (schema) => {
  return (req, res, next) => {
    const { error, value } = schema.validate(req.body, {
      abortEarly: false,
      stripUnknown: true
    });

    if (error) {
      return res.status(400).json({
        success: false,
        error: {
          code: 'VALIDATION_ERROR',
          message: 'Input validation failed',
          details: error.details.map(detail => ({
            field: detail.path.join('.'),
            message: detail.message
          }))
        }
      });
    }

    // Sanitize string fields
    Object.keys(value).forEach(key => {
      if (typeof value[key] === 'string') {
        value[key] = sanitizeHtml(value[key]);
      }
    });

    req.body = value;
    next();
  };
};

SQL Injection Prevention

// Use parameterized queries with Knex.js
const getUserByEmail = async (email) => {
  return await knex('users')
    .where({ email })  // Parameterized query
    .first();
};

// Never use string interpolation for queries
// BAD: await knex.raw(`SELECT * FROM users WHERE email = '${email}'`);
// GOOD: await knex('users').where({ email });

XSS Prevention

// frontend/src/utils/security.ts
import DOMPurify from 'dompurify';

// Sanitize user-generated content
export const sanitizeContent = (content) => {
  return DOMPurify.sanitize(content, {
    ALLOWED_TAGS: ['p', 'br', 'strong', 'em', 'u', 'ol', 'ul', 'li', 'a'],
    ALLOWED_ATTR: ['href', 'class', 'target'],
    ALLOW_DATA_ATTR: false
  });
};

// Escape HTML in templates
export const escapeHtml = (text) => {
  const div = document.createElement('div');
  div.textContent = text;
  return div.innerHTML;
};

🔒 Data Encryption

Encryption at Rest

// backend/src/utils/encryption.ts
import crypto from 'crypto';

class EncryptionService {
  constructor() {
    this.algorithm = 'aes-256-gcm';
    this.secretKey = crypto.scryptSync(process.env.ENCRYPTION_KEY, 'salt', 32);
  }

  encrypt(text) {
    const iv = crypto.randomBytes(16);
    const cipher = crypto.createCipher(this.algorithm, this.secretKey);
    cipher.setAAD(Buffer.from('hostingco', 'utf8'));

    let encrypted = cipher.update(text, 'utf8', 'hex');
    encrypted += cipher.final('hex');

    const authTag = cipher.getAuthTag();

    return {
      encrypted,
      iv: iv.toString('hex'),
      authTag: authTag.toString('hex')
    };
  }

  decrypt(encryptedData) {
    const decipher = crypto.createDecipher(this.algorithm, this.secretKey);
    decipher.setAAD(Buffer.from('hostingco', 'utf8'));
    decipher.setAuthTag(Buffer.from(encryptedData.authTag, 'hex'));

    let decrypted = decipher.update(encryptedData.encrypted, 'hex', 'utf8');
    decrypted += decipher.final('utf8');

    return decrypted;
  }
}

export const encryptionService = new EncryptionService();

Environment Variable Encryption

# Encrypt sensitive environment variables
echo "DATABASE_URL=postgresql://user:pass@host/db" | openssl enc -aes-256-cbc -base64 -pass pass:your-encryption-key

# Store encrypted value in .env
DATABASE_ENCRYPTED=U2FsdGVkX1+...

# Decrypt in application
const decryptEnvVar = (encryptedValue) => {
  return execSync(`echo "${encryptedValue}" | openssl enc -aes-256-cbc -d -base64 -pass pass:${process.env.ENCRYPTION_KEY}`).toString();
};

export const detectSuspiciousActivity = async (activity) => {
  const { userId, ipAddress, action } = activity;

  // Check for multiple failed logins
  if (action === 'login_failed') {
