After you purchase an Anti-DDoS Origin instance, you must add your asset that is assigned a public IP address to the instance for protection. This way, Anti-DDoS Origin provides the default mitigation capability for the asset. If the protected project encounters cross-border DDoS attacks and your service does not involve cross-border traffic, you can enable cross-border traffic blocking to quickly block cross-border traffic. This topic describes how to add an object for protection and enable cross-border traffic blocking for the protected object.
Add an object for protection
If you use an Anti-DDoS Origin instance for the first time, you must follow the instructions that are provided on the page to complete the authorization for the assets within your Alibaba Cloud account.
Scenario 1: Add an object to an Anti-DDoS Origin 1.0 (Subscription) instance
The instance can only be an Anti-DDoS Origin Enterprise instance and protect an asset of a regular Alibaba Cloud service.
Log on to the Traffic Security console.
In the top navigation bar, select the resource group to which the instance belongs and the region in which the instance resides.
In the left-side navigation pane, choose .
On the Protected Objects page, select the instance that you purchased and click Add Object for Protection.
In the Add Object for Protection dialog box, click the Add Asset or Add Manually tab and add an asset for protection. Then, click Confirm.
Add Asset: Select an asset that belongs to the current Alibaba Cloud account.
Add Manually: Enter the public IP address of the asset that belongs to the current Alibaba Cloud account.
Scenario 2: Add an object to an Anti-DDoS Origin 2.0 (Subscription) instance
The instance can be an Anti-DDoS Origin Enterprise instance or an Anti-DDoS Origin instance of Inclusive Edition for Small and Medium Enterprises and protect an asset of a regular Alibaba Cloud service.
Log on to the Traffic Security console.
In the top navigation bar, select the resource group to which the instance belongs and All Regions.
In the left-side navigation pane, choose .
On the Protected Objects page, select the instance that you purchased and click Add Object for Protection.
In the Add Object for Protection dialog box, click the Add Asset or Add Manually tab and add an asset for protection. Then, click Confirm.
Add Asset: Select an asset that belongs to the current Alibaba Cloud account.
Add Manually: Enter the public IP address of the asset that belongs to the current Alibaba Cloud account.
Scenario 3: Add an object to an Anti-DDoS Origin 2.0 (Pay-as-you-go) instance
The instance can protect an asset of a regular Alibaba Cloud service or an elastic IP address (EIP) with Anti-DDoS (Enhanced) enabled.
Asset of a regular Alibaba Cloud service: You can perform the following operations to add the asset to the instance.
EIP with Anti-DDoS (Enhanced) enabled: After you purchase an EIP with Anti-DDoS (Enhanced) enabled, the EIP with Anti-DDoS (Enhanced) enabled is automatically added for protection. You do not need to manually add the EIP with Anti-DDoS (Enhanced) enabled. You can view the purchased EIP with Anti-DDoS (Enhanced) enabled on the EIP with Anti-DDoS (Enhanced) Enabled tab of the Protected Objects page.
Log on to the Traffic Security console.
In the top navigation bar, select the resource group to which the instance belongs and All Regions.
In the left-side navigation pane, choose .
On the Protected Objects page, select the instance that you purchased and click Add Object for Protection.
In the Add Object for Protection dialog box, click the Add Asset or Add Manually tab and add an asset for protection. Then, click Confirm.
Add Asset: Select an asset that belongs to the current Alibaba Cloud account.
Add Manually: Enter the public IP address of the asset that belongs to the current Alibaba Cloud account.
Scenario 4: Add an asset of a member for protection after you enable the multi-account management feature
If your Alibaba Cloud account has the multi-account management feature enabled and is the management account, you can add assets of members for protection. For more information, see Use the multi-account management feature.
You can enable the multi-account management feature only for Anti-DDoS Origin 2.0 (Subscription) Enterprise instances and Anti-DDoS Origin 2.0 (Pay-as-you-go) instances.
Asset of a regular Alibaba Cloud service: You can perform the following operations to add the asset to the instance.
EIP with Anti-DDoS (Enhanced) enabled: After the multi-account management feature is enabled, an EIP with Anti-DDoS (Enhanced) enabled that is purchased by a member is automatically added for protection. You do not need to manually add the EIP with Anti-DDoS (Enhanced) enabled. You can view the purchased EIP with Anti-DDoS (Enhanced) enabled on the EIP with Anti-DDoS (Enhanced) Enabled tab of the Protected Objects page.
Log on to the Traffic Security console.
In the top navigation bar, select the resource group to which the instance belongs and All Regions.
In the left-side navigation pane, choose .
On the Protected Objects page, select the instance that you purchased and click Add Object for Protection.
In the Add Object for Protection dialog box, click the Add Assets of Members and click Confirm.
Enable cross-border traffic blocking for a protected object
The cross-border traffic blocking mitigation policy has a validity period and can be used only 10 times per month. We recommend that you enable this type of mitigation policy when a DDoS attack occurs.
The cross-border traffic blocking mitigation policy discards all cross-border service traffic within a specified blocking period. This policy is suitable for scenarios in which your service does not involve cross-border traffic. The cross-border traffic blocking mitigation policy typically discards traffic from specific regions based on the location of the attack source by using core routers in the backbone network of an Internet service provider (ISP).
If the protected asset resides in the Chinese mainland, the cross-border traffic blocking mitigation policy blocks all traffic from outside the Chinese mainland.
If the protected asset resides outside the Chinese mainland, the cross-border traffic blocking mitigation policy blocks all traffic from the Chinese mainland.
If your asset receives DDoS attacks, you can log on to the Traffic Security console and view the details of the attack on the Attack Analysis page. If the attack traffic comes from cross-border IP addresses, you can enable the cross-border traffic blocking mitigation policy for the asset. After the blocking period that you specify ends, the policy automatically stops blocking cross-border traffic. If you no longer want to block cross-border traffic, you can manually disable cross-border traffic blocking before the blocking period ends.
Log on to the Traffic Security console.
In the top navigation bar, select the resource group to which the instance belongs and the region in which the instance resides.
Anti-DDoS Origin 1.0 (Subscription) instance: Select the region in which the instance resides.
Anti-DDoS Origin 2.0 (Subscription) instance and Anti-DDoS Origin 2.0 (Pay-as-you-go) instance: Select All Regions.
In the left-side navigation pane, choose .
Select the required instance, find the IP address of the asset that you want to manage, turn on the switch in the Cross-Border Traffic Blocking column, and configure the blocking period.
NoteThe blocking period can be 30 minutes to 1 day. You cannot directly change the blocking period after your configure it. If you want to change the blocking period, you must disable cross-border traffic blocking and enable it again.
You can view the Start Time and End Time that you specify for an asset in the asset list. After the blocking period ends, cross-border traffic blocking is automatically disabled and the switch in the Cross-Border Traffic Blocking column is turned off.

FAQ
References
After an asset is added, the Mitigation Policy column displays Default, which indicates that the default mitigation capability of Anti-DDoS Origin is provided for the asset. If you want to allow or deny service traffic that has specific characteristics, you can create a custom mitigation policy and attach the policy to the asset. For more information, see Configure IP-specific mitigation policies and Configure port-specific mitigation policies.
WarningWhen you attach a port-specific mitigation policy to a port, a transient connection that lasts a few seconds occurs on your TCP-based services. We recommend that you attach a port-specific mitigation policy to a port during off-peak hours.
Assets of regular Alibaba Cloud services support only IP-specific mitigation policies. EIPs with Anti-DDoS (Enhanced) enabled support both IP-specific and port-specific mitigation policies. If you configure both IP-specific and port-specific mitigation policies, IP-specific mitigation policies have a higher priority.
