Configuring Scenarios

Last updated: 2020-04-22 13:28:21

    Use Cases

    Anti-DDoS Pro supports custom advanced DDoS protection policies. You can customize protection policies according to your business characteristics or the nature of attacks. In general, you can associate at most one advanced DDoS protection policy with an Anti-DDoS Pro instance. If you have multiple instances, you can configure up to 5 advanced DDoS protection policies.
    You may need to continuously optimize the policies to keep up with actual business needs and ever-changing attacks. To streamline the management of refined DDoS protection, Anti-DDoS Pro allows you to create scenarios. You can create scenarios, and the backend can collect, identify, and automatically generate advanced protection policies for flexible configuration or maintenance of policies.

    Creating a Scenario

    • Method 1:
      If you have not configured any scenario for your Anti-DDoS Pro instance yet, when you log in to the Anti-DDoS Console and select Anti-DDoS Pro > Protection Configuration on the left sidebar, you will see a message as shown below. Click Create Now to create a scenario.

      You can create up to 5 scenarios.

    • Method 2:
    1. Log in to the Anti-DDoS Console and select Anti-DDoS Pro > Protection Configuration on the left sidebar. Select the Advanced DDoS Protection Policy tab and click Create Scenario.
    2. In the Create Scenario box, configure the following parameters according to your business characteristics and click OK to complete the configuration.
      • Scenario Name: required; enter a scenario name containing 1–32 characters of any type.
        • Platform: select the development platform of your business. The options include PC client, mobile, TV, and CVM.
        • Category: select a service category. The options include game, application, website, and others.
        • Basic Information:
          • Current Protocol: select the protocol currently in use. The options include ICMP, TCP, UDP, and others.

            If you select TCP or UDP, you will need to enter the TCP/UDP service port range (1–65535). You will also see an item in the Other Information section where you can configure the length of TCP/UDP service packet (optional; the length range is 0–1500).

          • Users outside China
            Select Yes or No, indicating disabling or enabling Reject traffic from outside China.
          • Actively initiate outbound TCP requests
            Select Yes or No. If you select Yes, you need to enter the ports that initiate outbound TCP requests. Use commas (,) to separate multiple ports.
          • Actively initiate outbound UDP requests, such as DNS, NTP requests
            Select Yes or No. If you select Yes, you need to enter the ports that initiate outbound UDP requests. Use commas (,) to separate multiple ports.
        • Other Info: click Expand to configure more parameters.
          • UDP payload with fixed characteristic
            Select Yes or No. No is selected by default. If you select Yes, you need to enter the UDP payload characteristic.
          • TCP payload with fixed characteristic
            Select Yes or No. No is selected by default. If you select Yes, you need to enter the TCP payload characteristic.
          • Web API application
            Select Yes or No. No is selected by default. If you selected Yes, you need to enter the API service URL(s). Use commas (,) to separate multiple URLs.
          • VPN application
            Select Yes or No. No is selected by default. If you select Yes, "Other protocols" will not be disabled.

            If "Other protocols" in "Current Protocol" or Yes in "VPN application" is selected, then "Other protocols" will not be disabled.

    1. The backend will analyze the scenario you created and then automatically generate an advanced protection policy named in the format of scenario name_policy_Number, such as test_policy_1. You can then configure or modify the protection policy as needed.
      • If you have only one Anti-DDoS Pro instance and have created only one scenario, the generated advanced protection policy will be automatically associated with the instance.
      • If you modify the scenario information, the related configuration items in the corresponding advanced protection policy will be automatically modified to keep up with the changes to the scenario. However, changes to the advanced policy will not be synchronized to the corresponding scenario.

    Modifying and Deleting a Scenario

    1. Log in to the Anti-DDoS Console and select Anti-DDoS Pro > Protection Configuration on the left sidebar.
    2. In the Advanced DDoS Protection Policy tab, click Configure or Delete to the right of the target scenario to modify or delete the scenario.

      If a scenario is deleted, the advanced protection policy corresponding to the scenario will also be deleted.
