Security Guide

Overview

This document outlines the security measures and best practices implemented in the DysonASI Platform. It covers authentication, authorization, data protection, and other security considerations.

Authentication

JWT Implementation

  1. Token Structure:
interface JWTPayload {
  userId: string;
  email: string;
  role: string;
  iat: number;
  exp: number;
}
  1. Token Generation:
const generateToken = (user: User) => {
  return jwt.sign(
    {
      userId: user._id,
      email: user.email,
      role: user.role
    },
    process.env.JWT_SECRET,
    { expiresIn: '24h' }
  );
};
  1. Token Validation:
const validateToken = (token: string) => {
  try {
    return jwt.verify(token, process.env.JWT_SECRET);
  } catch (error) {
    throw new Error('Invalid token');
  }
};

Authorization

Role-Based Access Control (RBAC)

  1. User Roles:
enum UserRole {
  ADMIN = 'admin',
  USER = 'user',
  VIEWER = 'viewer'
}
  1. Permission Matrix:
const permissions = {
  [UserRole.ADMIN]: ['read', 'write', 'delete', 'manage_users'],
  [UserRole.USER]: ['read', 'write'],
  [UserRole.VIEWER]: ['read']
};
  1. Middleware Implementation:
const checkPermission = (requiredPermission: string) => {
  return (req: Request, res: Response, next: NextFunction) => {
    const userRole = req.user.role;
    if (!permissions[userRole].includes(requiredPermission)) {
      return res.status(403).json({ error: 'Insufficient permissions' });
    }
    next();
  };
};

Data Protection

Password Hashing

  1. Implementation:
const hashPassword = async (password: string): Promise<string> => {
  const salt = await bcrypt.genSalt(10);
  return bcrypt.hash(password, salt);
};
  1. Password Validation:
const validatePassword = async (
  password: string,
  hashedPassword: string
): Promise<boolean> => {
  return bcrypt.compare(password, hashedPassword);
};

Data Encryption

  1. Sensitive Data Encryption:
const encryptData = (data: string): string => {
  const cipher = crypto.createCipher('aes-256-cbc', process.env.ENCRYPTION_KEY);
  let encrypted = cipher.update(data, 'utf8', 'hex');
  encrypted += cipher.final('hex');
  return encrypted;
};
  1. Data Decryption:
const decryptData = (encryptedData: string): string => {
  const decipher = crypto.createDecipher('aes-256-cbc', process.env.ENCRYPTION_KEY);
  let decrypted = decipher.update(encryptedData, 'hex', 'utf8');
  decrypted += decipher.final('utf8');
  return decrypted;
};

API Security

Rate Limiting

  1. Implementation:
const rateLimiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100, // limit each IP to 100 requests per windowMs
  message: 'Too many requests from this IP, please try again later.'
});

Input Validation

  1. Request Validation:
const validateRequest = (schema: Joi.Schema) => {
  return (req: Request, res: Response, next: NextFunction) => {
    const { error } = schema.validate(req.body);
    if (error) {
      return res.status(400).json({ error: error.details[0].message });
    }
    next();
  };
};
  1. Example Schema:
const userSchema = Joi.object({
  username: Joi.string().min(3).max(30).required(),
  email: Joi.string().email().required(),
  password: Joi.string().min(8).required()
});

Frontend Security

XSS Prevention

  1. Content Security Policy:
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline';">
  1. Input Sanitization:
const sanitizeInput = (input: string): string => {
  return DOMPurify.sanitize(input);
};

CSRF Protection

  1. Implementation:
const csrfProtection = csrf({ cookie: true });
app.use(csrfProtection);
  1. Token Generation:
const generateCSRFToken = (req: Request): string => {
  return req.csrfToken();
};

Database Security

MongoDB Security

  1. Connection String:
const mongoURI = `mongodb://${username}:${password}@${host}:${port}/${database}?authSource=admin`;
  1. Index Security:
// Create indexes for frequently queried fields
db.collection.createIndex({ email: 1 }, { unique: true });

Data Backup

  1. Backup Schedule:
# Daily backup
0 0 * * * mongodump --uri="mongodb://localhost:27017/dysonasi" --out=/backup/daily/

# Weekly backup
0 0 * * 0 mongodump --uri="mongodb://localhost:27017/dysonasi" --out=/backup/weekly/

Monitoring and Logging

Security Logging

  1. Implementation:
const securityLogger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'security.log' })
  ]
});
  1. Log Events:
const logSecurityEvent = (event: SecurityEvent) => {
  securityLogger.info({
    timestamp: new Date(),
    event: event.type,
    userId: event.userId,
    ip: event.ip,
    details: event.details
  });
};

Incident Response

Security Incident Protocol

  1. Detection:
  • Monitor security logs
  • Set up alerts for suspicious activities
  • Regular security audits
  1. Response:
  • Isolate affected systems
  • Investigate the incident
  • Document findings
  • Implement fixes
  • Update security measures
  1. Recovery:
  • Restore from backups if necessary
  • Update security policies
  • Conduct post-incident review
