Drupal Security Best Practices for 2024

Security should be a top priority for every Drupal site. This guide covers the essential practices to keep your site safe in 2024.

Keep Everything Updated

Core Updates

Drupal core updates often include critical security patches:

• Enable automatic security updates
• Subscribe to security advisories
• Test updates in staging before production

Module Updates

Outdated modules are a common attack vector:

# Check for available updates
drush pm:updatestatus

# Apply security updates only
drush pm:security

Implement Strong Access Controls

User Roles and Permissions

Follow the principle of least privilege:

• Create specific roles for different user types
• Grant only necessary permissions
• Regularly audit user access
• Remove inactive accounts

Two-Factor Authentication

Enable 2FA for all administrative accounts:

# Using TFA module
composer require drupal/tfa

Secure Your Configuration

File Permissions

Set correct file permissions:

# Drupal recommended permissions
find . -type f -exec chmod 644 {} ;
find . -type d -exec chmod 755 {} ;
chmod 444 sites/default/settings.php

Sensitive Data

Never commit sensitive data:

• Use environment variables for API keys
• Store credentials outside web root
• Encrypt database connections

Database Security

Connection Security

Use SSL for database connections:

// settings.php
$databases['default']['default'] = [
  'driver' => 'mysql',
  'database' => 'mydb',
  'username' => 'user',
  'password' => 'pass',
  'host' => 'localhost',
  'prefix' => '',
  'pdo' => [
    PDO::MYSQL_ATTR_SSL_CA => '/path/to/ca-cert.pem',
    PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => TRUE,
  ],
];

SQL Injection Prevention

Always use parameterized queries:

// Good
$query = Drupal::database()->select('users', 'u')
  ->fields('u', ['uid', 'name'])
  ->condition('uid', $user_id)
  ->execute();

// Bad - Never do this!
$query = "SELECT * FROM users WHERE uid = $user_id";

Web Application Firewall

Druvance WAF

Our platform includes a built-in WAF:

• Blocks common attack patterns
• Rate limiting for API endpoints
• IP-based access controls
• Real-time threat intelligence

Custom Rules

Create custom WAF rules:

# Block specific user agents
if ($http_user_agent ~* "badbot") {
  return 403;
}

Regular Security Audits

Automated Scanning

Use security scanning tools:

• **Drush Security Check** - Check for known vulnerabilities
• **Druvance Security Scan** - Platform-level security assessment
• **Third-party Audits** - Annual penetration testing

Log Monitoring

Monitor security events:

# Watch for failed login attempts
tail -f /var/log/druvance/security.log | grep "login_failed"

Backup Strategy

The 3-2-1 Rule

• **3** copies of your data
• **2** different storage media
• **1** offsite backup

Druvance Backups

Our platform provides:

• Daily automated backups
• Point-in-time recovery
• 30-day retention
• One-click restore

Incident Response

Have a Plan

Prepare for security incidents:

1. **Detection** - Monitor for anomalies

1. **Containment** - Isolate affected systems

1. **Investigation** - Determine scope and cause

1. **Recovery** - Restore from clean backups

1. **Lessons Learned** - Improve defenses

Druvance Support
