Security Best Practices for PHP and Vue.js Development: Preventing Clickjacking Attacks

Clickjacking is a common web security threat. In this article, we will explore how to use PHP and Vue .js to develop secure applications and provide best practices for preventing clickjacking attacks.

Clickjacking means that the attacker creates a hidden IFrame and covers the target website or application in the underlying IFrame, allowing the user to click on the hidden IFrame without knowing it, thereby performing malicious operations. To prevent clickjacking attacks, we can take the following steps.

1. Set the X-Frame-Options header
   X-Frame-Options is an HTTP response header used to control how web pages are displayed in other websites. Using the X-Frame-Options header, we can specify whether the web page is allowed to be displayed in an IFrame. Here is a sample code:

header("X-Frame-Options: SAMEORIGIN");

In this example, we set the X-Frame-Options header to SAMEORIGIN, which means that the web page can only be displayed in IFrames in the same domain. This will effectively prevent clickjacking attacks.

2. Use the keep-alive component of Vue.js
   The keep-alive component of Vue.js can cache the state of the component so that it remains unchanged when re-rendered. This is useful when preventing clickjacking attacks, as the attacker cannot execute malicious code within the hidden IFrame.

The following is a sample code using the keep-alive component of Vue.js:

<template>
  <div>
    <keep-alive>
      <router-view></router-view>
    </keep-alive>
  </div>
</template>

In this example, we use the keep-alive component to wrap the router-view component, In this way, when the page is re-rendered, the status of the router-view component will be cached, effectively preventing click hijacking attacks.

3. Using the Referrer policy
   The Referrer policy is a policy used to control the rejection of requests that reach the target web page. By using the Referrer policy, we can limit access to specific sources and prevent clickjacking attacks.

The following is a sample code using the Referrer policy:

header("Referrer-Policy: strict-origin");

In this example, we set the Referrer policy to strict-origin, which means that only requests from the same domain name will be accepted. This will effectively prevent clickjacking attacks.

To sum up, using the development security best practices of PHP and Vue.js, we can effectively prevent clickjacking attacks. By setting the X-Frame-Options header, using Vue.js’ keep-alive component and the Referrer strategy, we can protect our application from clickjacking attacks. Hope this article is helpful to you.
