Help Center/ Anti-DDoS Service/ Getting Started/ Using CNAD Basic for Free

Using CNAD Basic for Free

Updated on 2024-11-08 GMT+08:00

If you have purchased Huawei Cloud EIPs, you can use CNAD Basic for free.

CNAD Basic offers EIPs Layer 4 protection against DDoS attacks and real-time alarm notifications, enhancing bandwidth utilization and ensuring the stable operation of user services.

CNAD Basic monitors the service traffic from the Internet to elastic public IP addresses (EIPs) to detect attack traffic in real time. It then scrubs attack traffic based on user-configured defense policies without interrupting services. It also generates monitoring reports that provide visibility into the network traffic security.

CNAD Basic automatically activates protection for EIPs on Huawei Cloud. You can simply configure alarm notifications and protection policies to access the protection features of CNAD Basic.

Procedure

This section describes how to quickly configure CNAD Basic protection for an EIP. Figure 1 shows the process.

Figure 1 Procedure

Step

Description

Prerequisites

Register a Huawei ID, enable Huawei Cloud, grant CNAD Basic permissions, and prepare protected objects.

Step 1: Viewing the EIP Status

Check whether the protected objects are synchronized to the CNAD Basic console and whether the default protection is enabled.

Step 2: Enabling Alarm Notifications

Set traffic scrubbing alarm notifications for protected objects.

Step 3: Configuring a DDoS Protection Policy

Configure traffic scrubbing policies for protected objects.

Step 4: Viewing a Monitoring Report

View the protection status and traffic details of protected objects.

Prerequisites

  1. Before using CNAD Basic, register a Huawei ID and enable Huawei Cloud. For details, see Registering a Huawei ID and Enabling Huawei Cloud Services and Real-Name Authentication.

    If you have enabled Huawei Cloud and completed real-name authentication, skip this step.

  2. Ensure that the account has been assigned related permissions. For details, see Creating a User Group and Assigning the Anti-DDoS Access Permission.
  3. Create an ECS and bind an EIP to it. For details, see section Purchasing an ECS.
    NOTE:

    If you have an ECS that meets the requirements, you do not need to create one again.

Step 1: Viewing the EIP Status

  1. Click in the upper left corner of the page and choose Security & Compliance > Anti-DDoS Service. The Anti-DDoS page is displayed.
  2. On the Public IP Addresses tab, ensure that the EIP prepared in Prerequisites has been synchronized to CNAD Basic and the default protection has been enabled for it.

    Figure 2 Viewing public IP address

Step 2: Enabling Alarm Notifications

  1. Click the Alarm Notifications tab.
  2. Enable the alarm notification function, set alarm parameters, and click Apply.

    Figure 3 Configuring alarm notifications
    Table 1 Parameter description

    Parameter

    Example Value

    Description

    Scrubbed Traffic Alarm Threshold

    1000Kbps

    When the volume of scrubbed traffic reaches the threshold, an alarm notification is sent. Set the threshold as required.

    Alarm Notifications

    Set the alarm switch to to enable the alarm function.

    You will receive notifications (by SMS or email) if a DDoS attack is detected on your EIP.

    SMN Topic

    -

    You can select an existing topic or click View Topic to create a topic.

    For details about how to create a topic, see Creating a Topic.

Step 3: Configuring a DDoS Protection Policy

  1. Click the Public IP Addresses tab, locate the row that contains the target public IP address, and click Set Protection.

    Figure 4 Protection settings

  2. Modify the protection settings as required and click OK.

    Figure 5 Modifying protection settings
    Table 2 Parameter description

    Parameter

    Example Value

    Description

    Set Protection

    Custom

    The default protection level is 120 Mbit/s, but you can manually adjust to higher levels if needed.

    Traffic Cleaning Threshold

    150Mbps

    You are advised to set a value closest to, but not exceeding, the purchased bandwidth.

    CNAD Basic scrubs traffic when detecting that the inbound traffic of an IP address exceeds the threshold.

Step 4: Viewing a Monitoring Report

  1. Click the Public IP Addresses tab, locate the row that contains the target public IP address, and click View Monitoring Report.

    Figure 6 Viewing a monitoring report

    You can view the protection status, traffic details, and attack events of a public IP address within the last 24 hours.

    Figure 7 Monitoring details

Related Information

  • Event monitoring can be enabled for a protected EIP, which triggers an alarm when events like scrubbing, blocking, or unblocking occur. For details, see Setting Event Alarm Notifications.
  • If you want to enable attack logging for a protected EIP for subsequent analysis and O&M, you can enable LTS. For details, see Configuring LTS for Anti-DDoS Logging.
