How to use PHP and Vue.js to develop applications that defend against network scanning attacks

In today's digital age, network security is receiving more and more attention. Network scanning attacks have become a key issue in network security. To protect applications from network scanning attacks, developers need to take some effective defensive measures.

This article will introduce how to use PHP and Vue.js to develop an application that defends against network scanning attacks, and provide some code examples. We will achieve this goal by limiting user input, filtering malicious requests, and increasing network security awareness.

1. Restrict user input

A common way in network scanning attacks is through malicious input. To prevent this from happening, we need to restrict and validate user input.

In PHP, you can use the built-in filter function filter_var to validate user input. Here is an example that shows how to validate the email address entered by the user:

$email = $_POST['email'];

if(filter_var($email, FILTER_VALIDATE_EMAIL)){
  // 验证成功，继续处理
} else {
  // 验证失败，返回错误消息给用户
}

In Vue.js, you can bind the form input using the v-model directive and use v The -on:submit directive listens for form submission events. Here is an example showing how to validate a user-entered email address in Vue.js:

<template>
  <form @submit="handleSubmit">
    <input v-model="email" type="email" required>
    <button type="submit">提交</button>
  </form>
</template>

<script>
export default {
  data() {
    return {
      email: ''
    }
  },
  methods: {
    handleSubmit() {
      if(this.email){
        // 验证成功，继续处理
      } else {
        // 验证失败，返回错误消息给用户
      }
    }
  }
}
</script>

2. Filtering malicious requests

To prevent malicious requests from causing damage to the application , we need to filter and inspect the request.

In PHP, you can use the $_SERVER variable to obtain the request information, and use the strpos function to detect whether there are malicious keywords. Here's an example showing how to filter malicious requests in PHP:

$request_uri = $_SERVER['REQUEST_URI'];

if(strpos($request_uri, 'eval(') === false){
  // 请求合法，继续处理
} else {
  // 请求包含恶意关键字，返回错误消息给用户并终止处理
}

In Vue.js, you can use the axios library to send requests and interceptors to verify the request. Here is an example showing how to filter malicious requests in Vue.js:

import axios from 'axios';

axios.interceptors.request.use(config => {
  if(config.url.indexOf('eval(') === -1){
    return config;
  } else {
    return Promise.reject(new Error('包含恶意关键字的请求'));
  }
});

3. Enhance network security awareness

In addition to preventing network scanning attacks through technical means, Network security awareness should be strengthened. This includes educating users about cybersecurity and precautions.

In applications, we can increase cybersecurity awareness by forcing users to set complex passwords, use two-factor authentication, and regularly update software. Similarly, during the development process, we must always pay attention to the latest network security vulnerabilities and attack methods, and make timely adjustments and updates.

In summary, using PHP and Vue.js to develop applications that defend against network scanning attacks requires a combination of measures to limit user input, filter malicious requests, and enhance network security awareness. Hopefully, the code examples provided in this article can help developers better implement network security defenses. Cybersecurity is an ongoing task, and we should remain vigilant and constantly learn and update our defense knowledge.
