How to add website security monitoring function to WordPress plug-in

In today’s network environment, website security is becoming more and more important. As WordPress website administrators, there are some steps we should take to ensure our website is protected. A very useful way to do this is to add website security monitoring functionality to our WordPress plugin. This article will explain how to add this functionality to a WordPress plugin and provide some code examples to help you achieve this.

First of all, we need to understand what the website security monitoring function is. In short, it is a feature used to monitor and detect security vulnerabilities and threats to a website. By adding this functionality to our WordPress plugin, we can promptly detect and resolve potential security issues to protect our website and our users’ data.

Here are some code examples that can be added to the website security monitoring functionality of a WordPress plugin:

1. Monitoring file modifications

// 在插件激活时开始监测文件修改
function start_file_change_monitoring() {
    $plugin_dir = plugin_dir_path(__FILE__);
    $monitored_files = array(
        $plugin_dir . 'plugin-file.php',
        $plugin_dir . 'another-file.php'
    );

    foreach ($monitored_files as $file) {
        $original_file_hash = md5_file($file);
        add_option('original_file_hash_' . $file, $original_file_hash);
    }

    add_action('admin_init', 'check_file_modifications');
}

// 检查文件是否被修改
function check_file_modifications() {
    $plugin_dir = plugin_dir_path(__FILE__);
    $monitored_files = array(
        $plugin_dir . 'plugin-file.php',
        $plugin_dir . 'another-file.php'
    );

    foreach ($monitored_files as $file) {
        $original_file_hash = get_option('original_file_hash_' . $file);
        $current_file_hash = md5_file($file);

        if ($original_file_hash !== $current_file_hash) {
            // 发送通知或采取其他行动
        }
    }
}

2. Detection Malicious Code Injection

// 在每次页面加载时检查是否有恶意代码注入
function check_malicious_code_injection() {
    $content = file_get_contents($_SERVER['DOCUMENT_ROOT'] . '/index.php');

    if (strpos($content, 'eval(') !== false || strpos($content, 'base64_decode(') !== false) {
        // 发送通知或采取其他行动
    }
}

add_action('wp', 'check_malicious_code_injection');

3. Logging and Reporting

// 记录每次登录尝试，包括IP地址和登录时间
function log_login_attempt($username, $status) {
    $log_entry = date('Y-m-d H:i:s') . ' - Username: ' . $username . ', Status: ' . $status . ', IP: ' . $_SERVER['REMOTE_ADDR'] . PHP_EOL;
    file_put_contents(plugin_dir_path(__FILE__) . 'login-attempts.log', $log_entry, FILE_APPEND | LOCK_EX);
}

// 监听登录尝试
function listen_login_attempts($username, $errors) {
    if (isset($errors->errors['invalid_username']) && $errors->errors['invalid_username']) {
        log_login_attempt($username, 'Invalid Username');
    } elseif (isset($errors->errors['incorrect_password']) && $errors->errors['incorrect_password']) {
        log_login_attempt($username, 'Incorrect Password');
    }
}
add_action('wp_login_failed', 'listen_login_attempts', 10, 2);

You can implement website security monitoring by adding these code samples to your WordPress plugin Function. Of course, this is just a starting point and you can customize the functionality to suit your needs.

To summarize, in today’s Internet era, protecting website security is crucial. Adding website security monitoring functionality to WordPress plugins is an effective method. The code examples mentioned above can help you get started adding this powerful feature to your WordPress plugin. Remember, website security is an ongoing endeavor that requires continually updated and evolving security measures.
