Teach you how to use PHP and Vue.js to develop best practices for defending against information tampering attacks

In the digital age, information security issues have become increasingly prominent. Information tampering attacks are one of them, which refers to hackers maliciously modifying or tampering with data in a website or application, thereby causing damage to users and systems. To protect user information and website security, developers should take some defensive measures. In this article, we’ll cover best practices on how to defend against information tampering attacks using PHP and Vue.js development.

1. Input validation and filtering
   Input validation and filtering are the first line of defense against information tampering attacks. In PHP, you can use built-in functions such as filter_var() and htmlspecialchars() to validate and filter input data. For example, by verifying that the user's input is a valid URL, attacks that redirect to malicious websites can be prevented. In Vue.js, you can use the v-bind directive to bind user input, and the v-model directive to bidirectionally bind user-entered data.

The following is a sample code:

$url = $_GET['url'];

if (filter_var($url, FILTER_VALIDATE_URL)) {
   // 处理有效的URL
} else { 
   // 处理无效的URL
}

<input type="text" v-model="url">
<button @click="checkURL">检查URL</button>

<script>
new Vue({
  el: '#app',
  data: {
    url: ''
  },
  methods: {
    checkURL: function() {
      // 处理URL
    }
  }
})
</script>

2. Data encryption and decryption
   Encryption is one of the important means to prevent information tampering attacks. In PHP, sensitive data can be encrypted and decrypted using algorithms such as AES or RSA. In Vue.js, you can use the crypto-js library to perform front-end data encryption and decryption operations. Make sure sensitive data is encrypted during transmission to prevent hackers from stealing it.

The following is a sample code:

$privateKey = file_get_contents('rsa_private.key');
$data = $_POST['data'];

openssl_private_decrypt(base64_decode($data), $decrypted, $privateKey);

// 处理解密后的数据

<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.0.0/crypto-js.min.js"></script>

<script>
var privateKey = 'your_private_key';
var data = 'encrypted_data';

var decryptedData = CryptoJS.AES.decrypt(data, privateKey).toString(CryptoJS.enc.Utf8);

// 处理解密后的数据
</script>

3. Front-end and back-end separation and API authentication
   Front-end and back-end separation and API authentication are another effective method to defend against information tampering attacks . By deploying the front-end and back-end on separate servers, you can reduce the intrusion surface for attackers. At the same time, by implementing authentication and authorization mechanisms at API endpoints, information tampering by unauthorized users can be prevented.

In Vue.js, you can use the axios library to make API requests and add token or authentication information in the request header. In PHP, you can use JWT(Json Web Token) to generate and verify user tokens.

The following is a sample code:

axios.post('/api/updateUserInfo', data, {
  headers: {
    'Authorization': 'Bearer ' + token
  }
})
.then(response => {
  // 处理响应
})
.catch(error => {
  // 处理错误
});

// 验证JWT令牌
$jwt = $_SERVER['HTTP_AUTHORIZATION'];
$token = substr($jwt, 7);

use FirebaseJWTJWT;

$decoded = JWT::decode($token, $key, array('HS256'));

// 处理JWT令牌验证结果

To sum up, the best practices for using PHP and Vue.js to develop defense against information tampering attacks include input validation and filtering, data encryption and decryption, As well as front-end and back-end separation and API authentication. By taking these measures, you can improve the security of your system and protect your users' sensitive information. Of course, as developers, you should continue to learn and update security knowledge to keep up with hacker attacks and protect the security of users and systems.
