Security Best Practices

Security is paramount when connecting multiple WordPress sites to WP Automator. This guide covers essential security measures to protect your sites and data.

Security Overview

Your security strategy should cover:

Application Passwords vs Regular Passwords

Understanding the difference is crucial for security:

Credential Storage Best Practices

How WP Automator Stores Credentials

Your credentials are protected through:

• Secure Transmission: HTTPS/TLS for all data transfers
• Encrypted Storage: Credentials are encrypted in the database
• Access Control: Only authorized processes can decrypt credentials
• No Logging: Sensitive data is never written to logs

Your Responsibilities

Access Restrictions

IP Whitelisting (Optional)

For additional security, you can restrict API access to specific IP addresses if your hosting provider supports it:

User Role Restrictions

Create dedicated users with minimal permissions:

// Add to functions.php for custom role
add_role('api_editor', 'API Editor', [
    'read' => true,
    'edit_posts' => true,
    'publish_posts' => true,
    'edit_published_posts' => true,
    'delete_posts' => true,
    'edit_others_posts' => true,
    'upload_files' => true,
    // Explicitly exclude admin capabilities
    'install_plugins' => false,
    'activate_plugins' => false,
    'edit_theme_options' => false,
    'manage_options' => false
]);

API Rate Limiting

Prevent abuse with rate limiting:

// Add to WordPress functions.php
add_filter('rest_authentication_errors', function($result) {
    // Skip for non-API requests
    if (!defined('REST_REQUEST') || !REST_REQUEST) {
        return $result;
    }
    
    $ip = $_SERVER['REMOTE_ADDR'];
    $key = 'api_limit_' . $ip;
    $attempts = get_transient($key) ?: 0;
    
    if ($attempts > 60) { // 60 requests per minute
        return new WP_Error(
            'too_many_requests',
            'API rate limit exceeded',
            ['status' => 429]
        );
    }
    
    set_transient($key, $attempts + 1, 60);
    return $result;
});

Security Monitoring

Activity Logging

Track all API access to your WordPress sites:

// Log REST API requests
add_filter('rest_pre_dispatch', function($result, $server, $request) {
    error_log(sprintf(
        '[REST API] %s %s from %s',
        $request->get_method(),
        $request->get_route(),
        $_SERVER['REMOTE_ADDR']
    ));
    return $result;
}, 10, 3);

Essential Security Measures

Security Configuration

Add to wp-config.php:

// Disable file editing
define('DISALLOW_FILE_EDIT', true);

// Disable plugin/theme updates from admin
define('DISALLOW_FILE_MODS', true);

// Force SSL for admin
define('FORCE_SSL_ADMIN', true);

// Limit login attempts
define('WP_LOGIN_ATTEMPTS', 5);

// Hide WordPress version
remove_action('wp_head', 'wp_generator');

// Disable XML-RPC if not needed
add_filter('xmlrpc_enabled', '__return_false');

Recommended Security Plugins

API Security Headers

Configure security headers for REST API:

// Add to functions.php
add_action('rest_api_init', function() {
    header('X-Content-Type-Options: nosniff');
    header('X-Frame-Options: SAMEORIGIN');
    header('X-XSS-Protection: 1; mode=block');
    header('Referrer-Policy: strict-origin-when-cross-origin');
    header('Permissions-Policy: geolocation=(), microphone=(), camera=()');
});

Regular Security Audits

Monthly Checklist

• Review application passwords (last used dates)
• Check API access logs for anomalies
• Verify all users still need access
• Update WordPress, themes, and plugins
• Test backup restoration process
• Review security plugin alerts
• Check for unauthorized admin users

Quarterly Reviews

• Rotate all application passwords
• Full security plugin scan
• Review and update firewall rules
• Test incident response procedures
• Update documentation
• Security training for team members

Compliance Considerations

GDPR Compliance

When using WP Automator with EU sites:

1. Data Processing: Understand what data is being processed
2. Data Minimization: Only sync necessary data
3. User Rights: Respect user data deletion requests
4. Documentation: Keep records of your data processing activities

Security Standards

Ensure your WordPress sites follow industry best practices for security and data protection.

Frequently Asked Questions

Q: Is it safe to store WordPress credentials in WP Automator? A: Yes, credentials are encrypted with AES-256 and transmitted over TLS 1.3. We follow industry best practices for secure credential storage.

Q: Can WP Automator access my WordPress admin panel? A: No, application passwords only grant API access. They cannot be used to log into the WordPress admin interface.

Q: What happens if someone steals my app password? A: They could potentially create/edit content via the API. Immediately revoke the password and generate a new one. Check logs for unauthorized activity.

Q: Should I use the same app password for multiple sites? A: Never. Generate unique app passwords for each WordPress site to limit damage if one is compromised.

Q: How often should I change app passwords? A: We recommend rotating every 90 days, or immediately if you suspect any compromise.

Q: Can I restrict WP Automator to specific post types? A: Yes, use a custom role with limited capabilities or implement additional permission checks via WordPress hooks.
