Best Practices for Security in PHP and Vue.js Development: Preventing Network Scanning Attacks

Network attacks are a problem that cannot be ignored in today’s Internet environment. In order to ensure the security of the website, developers need to take a number of measures A series of measures to prevent network scanning attacks. As widely used development languages ​​and frameworks, PHP and Vue.js have some security best practices during the development process to improve the security of the website.

A common strategy to prevent network scanning attacks is to implement input filtering, which verifies and filters user-entered data to prevent the injection of malicious code. Here is the sample code to implement input filtering in PHP and Vue.js:

1. PHP to implement input filtering:

<?php
// 使用过滤器过滤用户输入的数据
$username = filter_input(INPUT_GET, 'username', FILTER_SANITIZE_STRING);
$email = filter_input(INPUT_GET, 'email', FILTER_SANITIZE_EMAIL);

// 运行过滤后的数据
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    // 存储到数据库或其他操作
    echo "输入的邮箱地址有效";
} else {
    echo "输入的邮箱地址无效";
}
?>

In the above code, use filter_inputFunction to obtain the data passed by the user through GET, and use FILTER_SANITIZE_STRING and FILTER_SANITIZE_EMAIL filters to process the data. Then, use the filter_var function to verify the email address. This ensures that the entered data does not contain malicious code.

2. Vue.js implements input filtering:

<template>
  <div>
    <input v-model="username" @input="sanitizeInput" placeholder="请输入用户名">
    <input v-model="email" @input="sanitizeInput" placeholder="请输入邮箱地址">
  </div>
</template>

<script>
export default {
  data() {
    return {
      username: '',
      email: ''
    };
  },
  methods: {
    sanitizeInput() {
      this.username = this.username.replace(/[^ws]/gi, '');
      this.email = this.email.replace(/[^w.@]/gi, '');
    }
  }
};
</script>

In the above code, use the v-model directive of Vue.js to filter the input box The data is two-way bound, and the @input event is used to monitor user input. In the sanitizeInput method, the input data is filtered by using regular expressions to ensure that it does not contain special characters. This prevents the injection of malicious code.

In addition to implementing input filtering, there are several other security best practices that can be adopted to improve the security of PHP and Vue.js applications.

1. Security best practices for PHP:
2. Use a secure password hashing algorithm to store user passwords, such as using the password_hash function and password_verify function.
3. Avoid using user input directly for SQL queries. You can use prepared statements or an ORM framework to prevent SQL injection attacks.
4. Ensure that sensitive data is encrypted using encryption algorithms during transmission, such as using the HTTPS protocol.
5. Security best practices for Vue.js:
6. Avoid using sensitive data, such as database connection information and API keys, on the client side. You can use the backend to handle this data.
7. For routes involving user authentication, use route guards to verify the user's login status.
8. Prevent cross-site scripting attacks (XSS), perform HTML escaping on user input, and avoid executing malicious scripts when displayed on the page.

To sum up, among the security best practices for PHP and Vue.js development, implementing input filtering is one of the important strategies to prevent network scanning attacks. In addition, it is also crucial to use secure password hashing algorithms, avoid using user input directly for SQL queries, and ensure that sensitive data is encrypted during transmission. By adopting these security best practices, developers can improve the security of their PHP and Vue.js applications, protecting user information and website reliability.
