Implementing Compliant Password Policies

Policy Documentation

Required elements:

PASSWORD SECURITY POLICY

1. PURPOSE
   Establish password requirements to comply with [frameworks]

2. SCOPE
   Applies to: All employees, contractors, systems

3. REQUIREMENTS
   - Minimum length: 12 characters
   - Complexity: Encouraged, not mandated
   - Expiration: Change when compromised
   - Reuse: No reuse of last 10 passwords
   - MFA: Required for all accounts
   - Storage: Password manager required

4. RESPONSIBILITIES
   - Users: Follow policy, report incidents
   - IT: Enforce policy, provide tools
   - Management: Ensure compliance

5. ENFORCEMENT
   - Violations: Progressive discipline
   - Exceptions: Documented, approved

6. REVIEW
   - Frequency: Annual
   - Authority: CISO/Security team

Technical Implementation

Password storage:

// Compliant password hashing
const bcrypt = require('bcrypt');
const saltRounds = 12; // OWASP recommendation

async function hashPassword(password) {
  // Check against breach database first
  if (await isPasswordBreached(password)) {
    throw new Error('Password found in breach database');
  }
  
  // Hash with bcrypt
  return await bcrypt.hash(password, saltRounds);
}

async function verifyPassword(password, hash) {
  return await bcrypt.compare(password, hash);
}

Password validation:

function validatePassword(password) {
  const errors = [];
  
  // Length check (compliance requirement)
  if (password.length < 12) {
    errors.push('Password must be at least 12 characters');
  }
  
  // Breach database check (NIST recommendation)
  if (isPasswordBreached(password)) {
    errors.push('Password found in data breaches');
  }
  
  // No user info (NIST requirement)
  if (containsUserInfo(password, user)) {
    errors.push('Password cannot contain personal information');
  }
  
  return errors;
}

Audit logging:

function logAuthenticationEvent(event) {
  logger.info('Authentication event', {
    timestamp: new Date(),
    userId: event.userId,
    action: event.action, // login, logout, failed_attempt
    ipAddress: event.ip,
    userAgent: event.userAgent,
    success: event.success,
    mfaUsed: event.mfaUsed
  });
}
