PHP DDoS attack protection and network security configuration recommendations in Huawei Cloud API interface docking

With the rapid development of cloud computing, more and more enterprises choose to migrate their business to cloud platforms. As a leading cloud service provider, Huawei Cloud provides a wealth of cloud computing products and services. Security has always been an important issue during the docking process of PHP Huawei Cloud API interface. This article will focus on how to ensure system security by configuring Huawei Cloud's DDoS attack protection function and network security settings. And combined with code examples, specific configuration suggestions are given.

1. Use Huawei Cloud DDoS protection function

DDoS attack refers to an attack method that consumes network resources by sending a large number of requests to the target server, causing the system to crash or become unable to access normally. In order to deal with DDoS attacks, Huawei Cloud provides DDoS protection services. The following are some configuration suggestions:

1. Enable DDoS protection service

Before connecting to the PHP Huawei Cloud API interface, you first need to enable the DDoS protection service. This can be done through the Huawei Cloud console or API calls. The following is a sample code for using API calls to enable DDoS protection services:

// 引入华为云SDK
require_once 'vendor/autoload.php';

use HuaweiCloudSDKDDoSConfigV1DDoSConfigClient;
use HuaweiCloudSDKDDoSConfigV1ModelCreateProtectableRequest;

$ak = 'your_ak';
$sk = 'your_sk';

$client = DDoSConfigClient::newBuilder()
    ->withAk($ak)
    ->withSk($sk)
    ->build();

$request = new CreateProtectableRequest();
$request->bodyParams([
    'instance_type' => 'ECS',
    'instance_id' => 'your_instance_id',
    'available_zone_id' => 'your_available_zone_id'
]);

$response = $client->createProtectable($request);

In the above example, you need to replace your_ak and your_sk with your Huawei Cloud access password key, your_instance_id and your_available_zone_id are replaced with your specific instance ID and availability zone ID.

2. Configuring access control policies

Huawei Cloud DDoS protection service supports configuring access control policies. You can set IP black and white lists, Cloud Shield business risk levels, and access limits according to actual needs. Wait. The following is sample code for configuring access control policies using API calls:

// 引入华为云SDK
require_once 'vendor/autoload.php';

use HuaweiCloudSDKDDoSConfigV1DDoSConfigClient;
use HuaweiCloudSDKDDoSConfigV1ModelUpdatePolicyRequest;

$ak = 'your_ak';
$sk = 'your_sk';

$client = DDoSConfigClient::newBuilder()
    ->withAk($ak)
    ->withSk($sk)
    ->build();

$request = new UpdatePolicyRequest();
$request->bodyParams([
    'instance_id' => 'your_instance_id',
    'policy_id' => 'your_policy_id',
    'enable_http' => 1,
    'protected_hosts' => [
        [
            'host_id' => 'your_host_id',
            'protected_host_type' => 'ip',
            'protected_host_value' => 'x.x.x.x'
        ]
    ]
]);

$response = $client->updatePolicy($request);

In the above example, you need to replace your_ak and your_sk with your Huawei Cloud access password key, your_instance_id and your_policy_id are replaced with your specific instance ID and policy ID, and x.x.x.x is replaced with the IP address you need to set.

2. Strengthen network security configuration

In addition to turning on the DDoS protection function, you also need to strengthen network security configuration to reduce the risk of system attacks. The following are some suggestions:

1. Use HTTPS protocol

When connecting to API interfaces, it is recommended to use HTTPS protocol for data transmission to ensure data security and integrity. You can use PHP's cURL function library to implement HTTPS requests. The following is a simple sample code:

$url = 'https://api.huaweicloud.com/v1/your_api_endpoint';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

$response = curl_exec($ch);

curl_close($ch);

In the above example, replace your_api_endpoint with your specific API interface address.

2. Use secure database query methods

When performing database queries, use secure query methods to prevent SQL injection attacks. PDO (PHP Data Objects) can be used to implement secure database operations. Here is a sample code:

$db_host = 'your_db_host';
$db_name = 'your_db_name';
$db_user = 'your_db_user';
$db_pass = 'your_db_pass';

try {
    $dsn = "mysql:host=$db_host;dbname=$db_name";
    $pdo = new PDO($dsn, $db_user, $db_pass);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = 'SELECT * FROM your_table WHERE id = :id';
    $stmt = $pdo->prepare($sql);
    $stmt->bindParam(':id', $id);
    $stmt->execute();

    $result = $stmt->fetch(PDO::FETCH_ASSOC);

    // 处理查询结果
} catch (PDOException $e) {
    // 异常处理
}

$pdo = null;

In the above example, replace your_db_host, your_db_name, your_db_user, and your_db_pass Enter your database connection information, replace your_table with your table name, and $id with the field you need to query.

To sum up, by enabling Huawei Cloud's DDoS protection function and strengthening network security configuration, the security of the system can be effectively guaranteed. At the same time, following safe coding standards and paying attention to the security of the code is also an important part of protecting system security.
