cdn除了加速外能防攻击么

// 初始化CDN客户端
const tencentcloud = require('tencentcloud-sdk-nodejs');
const cdnClient = new tencentcloud.cdn.v20180606.CdnClient({
  credential: {
    secretId: 'your_secret_id',
    secretKey: 'your_secret_key',
  },
  region: 'ap-guangzhou',
  profile: {
    httpProfile: {
      endpoint: 'cdn.tencentcloudapi.com',
    },
  },
});

// 配置防御策略
const params = {
  Domain: 'example.com',
  DefenseConfig: {
    DdosDefense: {
      Enable: true,
      Mode: 'auto',
    },
    CcDefense: {
      Enable: true,
      Mode: 'auto',
    },
    WafDefense: {
      Enable: true,
      RuleSetId: 'your_waf_rule_set_id',
    },
  },
};

cdnClient.ModifyDomainConfig(params).then(
  (data) => {
    console.log(data);
  },
  (err) => {
    console.error(err);
  }
);
