Complete guide to WordPress security protection!

With the development of the Internet, WordPress, as a popular content management system, is chosen to be used by more and more websites. However, security threats are also increasing, and website security issues have become the focus of the majority of WordPress website owners. In order to protect the security of the WordPress website, we need to take a series of security measures, including but not limited to strengthening the login system, installing security plug-ins, regularly backing up data, etc.

1. Reinforce the login system

1. Modify the default login path: Modify the WordPress default login path/wp-admin to a custom path, which can be modified by Code implementation in functions.php file:

function custom_login_url() {
    return home_url('login');
}
add_filter('login_url', 'custom_login_url');

function custom_login_redirect() {
    if ($_SERVER['REQUEST_URI'] == '/wp-login.php' || $_SERVER['REQUEST_URI'] == '/wp-admin/') {
        wp_redirect(home_url('login'));
        exit();
    }
}
add_action('init', 'custom_login_redirect');

2. Limit the number of login attempts: Use plug-ins or code to limit the number of failed login attempts to prevent malicious attacks:

function limit_login_attempts($no_of_attempts_allowed) {
    if ($number_failed_login_attempts >= $no_of_attempts_allowed) {
        return true;
    }
    return false;
}

2. Install security plug-ins

1. Install firewall plug-ins: For example, Wordfence Security plug-in can monitor website traffic and intercept malicious requests:

// 代码示例
function block_malicious_requests($request) {
    if (is_malicious_request($request)) {
        return new WP_Error('blocked_request', 'Your request has been blocked for security reasons.');
    }
    return $request;
}
add_filter('pre_http_request', 'block_malicious_requests');

2. Update plugins and themes regularly: Keeping WordPress core, plugins, and themes updated is an important measure to prevent your website from security threats.

3. Back up data regularly

1. Database backup: You can use plug-ins such as UpdraftPlus for database backup, and set up scheduled automatic backup to prevent data lost.

// 代码示例
function backup_database() {
    if (!$is_backup_in_progress) {
        // 备份数据库操作
        $is_backup_in_progress = true;
    }
}
add_action('init', 'backup_database');

2. File Backup: Back up the files of the WordPress website, including theme files, plug-in files, etc., so that the website can be restored when needed.

Through the above comprehensive security protection strategy, we can effectively protect the WordPress website from various network security threats. Hopefully these specific code examples will help you better strengthen your WordPress website security protection system. May your website always be safe and secure!
