Security Overview

NudgeCampaign implements enterprise-grade security measures to protect customer data, ensure platform integrity, and maintain compliance with global regulations. Our security program is built on industry best practices and continuously evolving to address emerging threats.

Security Principles

Defense in Depth

We implement multiple layers of security controls:

• Network security (firewalls, IDS/IPS)
• Application security (WAF, code scanning)
• Data security (encryption, access controls)
• Physical security (data center controls)
• Administrative security (policies, training)

Zero Trust Architecture

• Never trust, always verify
• Least privilege access
• Micro-segmentation
• Continuous verification
• Encrypted communications

Security by Design

• Security considerations in all phases
• Threat modeling for new features
• Security testing in CI/CD pipeline
• Regular security reviews
• Privacy by default

Security Governance

Threat Model

Threat Categories

    - Risk identification
    - Control evaluation
    - Compliance check
    
  4. Consultation:
    - Stakeholder input
    - Expert review
    - DPO consultation
    
  5. Documentation:
    - Record findings
    - Risk mitigation plan
    - Approval process

Security Best Practices

Development Security

Secure Coding Standards

// Secure Coding Examples

// 1. Input Validation
function validateUserInput(input) {
  // Whitelist validation
  const allowedCharacters = /^[a-zA-Z0-9\s\-_.@]+$/;
  
  if (!allowedCharacters.test(input)) {
    throw new ValidationError('Invalid characters in input');
  }
  
  // Length validation
  if (input.length > 255) {
    throw new ValidationError('Input too long');
  }
  
  // SQL injection prevention
  const sqlKeywords = ['SELECT', 'INSERT', 'UPDATE', 'DELETE', 'DROP'];
  const upperInput = input.toUpperCase();
  
  for (const keyword of sqlKeywords) {
    if (upperInput.includes(keyword)) {
      logSecurityEvent('Potential SQL injection', { input });
      throw new SecurityError('Invalid input detected');
    }
  }
  
  return input.trim();
}

// 2. Secure Password Handling
async function hashPassword(password) {
  const bcrypt = require('bcrypt');
  const saltRounds = 12;
  
  // Password complexity check
  if (!isPasswordComplex(password)) {
    throw new Error('Password does not meet complexity requirements');
  }
  
  return await bcrypt.hash(password, saltRounds);
}

// 3. Secure Session Management
class SecureSessionManager {
  createSession(userId) {
    const crypto = require('crypto');
    
    const session = {
      id: crypto.randomBytes(32).toString('hex'),
      userId: userId,
      createdAt: Date.now(),
      expiresAt: Date.now() + (30 * 60 * 1000), // 30 minutes
      ipAddress: this.getClientIP(),
      userAgent: this.getUserAgent()
    };
    
    // Store session securely
    this.storeSession(session);
    
    // Set secure cookie
    this.setSecureCookie('session_id', session.id, {
      httpOnly: true,
      secure: true,
      sameSite: 'strict',
      maxAge: 30 * 60 * 1000
    });
    
    return session;
  }
}

// 4. Secure API Calls
async function secureAPICall(endpoint, data) {
  const axios = require('axios');
  const crypto = require('crypto');
  
  // Sign request
  const timestamp = Date.now();
  const signature = crypto
    .createHmac('sha256', API_SECRET)
    .update(`${timestamp}${JSON.stringify(data)}`)
    .digest('hex');
  
  try {
    const response = await axios({
      method: 'POST',
      url: endpoint,
      data: data,
      headers: {
        'X-Timestamp': timestamp,
        'X-Signature': signature,
        'Content-Type': 'application/json'
      },
      timeout: 10000,
      validateStatus: (status) => status < 500
    });
    
    return response.data;
  } catch (error) {
    logSecurityEvent('API call failed', { endpoint, error: error.message });
    throw error;
  }
}
