Your functions.php file acts as the primary layout command center for your theme ecosystem. Securing this file—and leveraging it to secure other core infrastructure vulnerabilities—is step one for robust maintenance.
Hiding Your WordPress Version Number
By default, WordPress publicly prints out its active version core tag in page headers. Hackers run automated scrapers looking for old versions with unpatched exploits. Add this simple code to block that output:
function remove_wp_version() {
return '';
}
add_filter('the_generator', 'remove_wp_version');
