アラートの設定

DDoS攻撃に備えるためのもう一つの重要な部分は、アプリケーションが攻撃を受けているときにそれを知ることです。

CloudflareはDDoS攻撃の通知を提供しており、これをアカウントで設定できます。

To set up a notification:

1. Log in to the Cloudflare dashboard ↗ and select your account.

2. Select Notifications.

3. Under Notifications, select Add.

4. Select one of the available DDoS alerts (depending on your plan and services):

   • HTTP DDoS Attack Alert
   • Layer 3/4 DDoS Attack Alert
   • Advanced HTTP DDoS Attack Alert
   • Advanced Layer 3/4 DDoS Attack Alert

5. Enter a notification name and (optionally) a description.

6. Configure a delivery method for the notification. The available delivery methods depend on your Cloudflare plan. For more information, refer to Cloudflare Notifications.

7. If you are creating a notification for one of the advanced DDoS attack alerts, select Next and define the parameters that will filter the notifications you will receive.

8. Select Save.
