Teach you how to use PHP and Vue.js to develop applications that defend against clickjacking (UI red patch) attacks

Clickjacking (Clickjacking) is a common network security threat that uses transparent overlays in The layer on the web page that induces users to click achieves the purpose of maliciously manipulating users and performing illegal acts. In order to improve user security, we can use a technology called UI red patching to combat this attack. This article will teach you how to use PHP and Vue.js to develop an application that can effectively defend against clickjacking attacks.

First of all, we need to understand what clickjacking is. Click hijacking uses a layer transparently covered on a Web page to induce users to click, directing the user's click operation to a malicious website, thereby achieving the purpose of maliciously operating the user. In order to combat this attack, we need to prevent users from being hijacked and clicked when browsing the web normally.

UI red patching is a technique that combats clickjacking by dynamically generating an overlay on the page, drawing it above the area visible to the user. This overlay blocks the user's mouse click events, preventing the user from hijacking clicks on the page. Below is an example of an application developed using PHP and Vue.js that demonstrates how to implement clickjacking defense.

First, we need to create an index.php file to load Vue.js and the application’s entry file app.js.

<!DOCTYPE html>
<html>
<head>
    <title>点击劫持防御应用程序</title>
    <script src="https://cdn.jsdelivr.net/npm/vue@2.6.11/dist/vue.js"></script>
    <script src="app.js"></script>
</head>
<body>
    <div id="app">
        <h1>点击劫持防御应用程序</h1>
        <button @click="handleClick">点击我</button>
    </div>
</body>
</html>

Copy after login

Next, we create a Vue.js entry file of app.js and define a Vue instance named app.

new Vue({
    el: '#app',
    methods: {
        handleClick: function () {
            // 在这里处理点击事件
            // 在点击事件处理函数中，我们可以添加代码来触发一些安全行为，如输入密码、修改账户信息等
            console.log('点击事件被触发');
        }
    }
});

Copy after login

In the above code, we defined a method named handleClick in the methods attribute of the Vue instance to handle the click event of the button. In this method, we can add code to trigger some safe behavior. In this example, we only print a console log.

Finally, we need to add the UI red patch function to the application to defend against clickjacking attacks. In the header of the index.php file, add the following code:

<?php
    header("Content-Security-Policy: frame-ancestors 'self'");
?>

Copy after login

The above code restricts the page to only be accessed by the frame within this page by setting the Content-Security-Policy header, thereby preventing cross-domain Clickjacking attack.

To sum up, we used PHP and Vue.js to develop an application that can effectively defend against clickjacking (UI red patch) attacks. By using UI red-patching techniques and setting the Content-Security-Policy header, we can protect users from clickjacking attacks. I hope this article will help you understand clickjacking defense technology, and also improve your ability to develop secure applications.
