Basic File and Server Hardening

Hardening your server and files is one of the first lines of defense against vulnerabilities. Here are some basic security measures:

• Disable PHP Error Reporting: By default, PHP error reporting can expose sensitive information about your site. This can be easily disabled by adding the following code to your wp-config.php file:

error_reporting(0);
@ini_set('display_errors', 0);

Alternatively, you can manage this through your hosting control panel. For more detailed guidance, refer to this tutorial from Hostinger.

• Turn Off File Editing: Prevent unauthorized users from modifying your theme and plugin files through WordPress admin. This can be accomplished by adding the following line to your wp-config.php:

define('DISALLOW_FILE_EDIT', true);

For additional instructions, read more at Hostinger.

• Restrict Access via .htaccess or Web Server Config: One effective way to secure critical files from unintended access is to restrict access to files such as wp-config.php and .htaccess. For Apache servers, you can add the following to your .htaccess:

    order allow,deny
    deny from all

This helps safeguard essential files from direct access. Further instructions can be found here.

• Delete Unused Themes and Plugins: Regularly cleaning your WordPress installation of unused and outdated themes or plugins is crucial as these can serve as common entry points for attackers.

Database Security Enhancements

Your database is a treasure trove of information, and securing it should be a top priority.

• Change the Default Database Prefix: During the initial installation, change the default database table prefix from w_ to something custom. This simple modification can make SQL injection attacks more challenging to execute, thereby increasing your site’s security posture.

Limit Potential Vulnerabilities

Reducing exposure to known security risks is another avenue for reinforcing your WordPress site.

• Disable XML-RPC: XML-RPC can be an entry point for brute force and DDoS attacks. To mitigate this risk, you can disable XML-RPC by adding the following to your theme’s functions.php:

add_filter('xmlrpc_enabled', '__return_false');

Alternatively, you can block access through .htaccess:

<Files xmlrpc.php>
    order deny,allow
    deny from all
</Files>

More details can be found at the Hostinger tutorial.

• Hide WordPress Version: Clearly displaying your WordPress version helps attackers identify potential vulnerabilities. You can remove this by adding the following to your functions.php:

remove_action('wp_head', 'wp_generator');

This simple action can enhance your website’s security profile.

Operational Security Practices

Operational practices play a vital role in maintaining the overall security of your WordPress site.

• Choose a Secure Web Host: Selecting a reputable hosting provider with a proven record concerning security features, such as firewalls and regular malware scans, can significantly reduce your site’s risk.
• Regular Backups: Establish a routine for backing up your website. While many plugins can automate this process, you can also schedule backups via your hosting control panel. Store these backups securely, preferably remotely, for maximal safety. For guidance, refer to WPBeginner.
• Use Strong Passwords and Unique Usernames: Avoid generic usernames like “admin” and ensure that all users have unique, complex passwords. Implementing strict password policies can reduce unauthorized access drastically. Learn more about effective policies at TAPP Network.
• Set Proper File Permissions: Adjust the file permissions for your core files and directories. Typically, directories should be set to 755 and files to 644, controlling who can read, write, and execute these files.
