ActionTrail：Create a single-account trail

Procedure

1. Log on to the ActionTrail console.

2. In the left-side navigation pane, click Trails.

3. In the top navigation bar, select the region where you want to create a single-account trail.

   Note

   The region that you select becomes the home region of the trail that you want to create.

4. On the Trails page, click Create Trail.

5. On the Create Trail page, configure the parameters.

   • Basic Information

     Parameter	Description
     Trail Name	The name of the trail, which is also the name of the Logstore. Note The name of the trail must be unique.
     Trail Configuration	The category of the events that you want to deliver. Valid values: Management Event: By default, Management Event is selected. You can select the type of management events that you want to deliver. Valid values: All: read and write events. Auditing-related regulations and standards stipulate that all events must be recorded. We recommend that you select All. Write: the events that record the operations to create, delete, or modify cloud resources. Example: the events that are generated when you call the CreateInstance operation to create a subscription or pay-as-you-go Elastic Compute Service (ECS) instance. If you want to export events only for analysis and focus only on the events that affect cloud resources, select Write. Read: the events that record the operations to read information about cloud resources, rather than to create, delete, or modify cloud resources. Example: the events that are generated when you call the DescribeInstances operation to query the details of one or more ECS instances. In most cases, a large number of read events are generated, and these events occupy a large storage space. However, auditing-related regulations and standards stipulate that all events must be recorded. We recommend that you configure a trail to deliver both read and write events. This helps you track the use of AccessKey pairs and access to cloud resources. Insights Event: Select or clear Insights Event based on your business requirements. After you select Insights Event, All is selected for Management Event. ActionTrail analyzes management events, identifies unusual activities that are associated with API call rates, API error rates, IP addresses, AccessKey pair call rates, permission changes, password changes, and trail concealment, and then generates Insights events. For more information about Insights events, see Overview of Insights events. Note By default, when you create a trail in the ActionTrail console, the trail delivers events in all regions. To create a trail that delivers events in specific regions, call the CreateTrail operation. Set TrailRegion based on your business requirements when you call this operation.

   • Event Delivery

     You can create a trail to deliver events to Simple Log Service, OSS, MaxCompute, or all these services. For more information about how to select a storage service, see Deliver events to specified Alibaba Cloud services.

     Note

     The trail delivers only the events that are generated after the single-account trail takes effect. The events that are generated in the last 90 days are not included. You can create a data backfill task to deliver the events that are generated in the last 90 days to the delivery destination that you specify for the trail at a time. For more information, see Create a data backfill task.

     • Select Delivery to Log Service.

       • If you select Delivery to Current Account, configure the parameters that are described in the following table.

         Parameter	Description
         Project	The project to which you want to deliver events. New Project Existing Project
         Logstore Region	The region where the Logstore resides.
         Project Name	The name of the project. Note The project name is shared by all Alibaba Cloud users and must be unique. If you select New Log Service Project, the system automatically creates a project. You must specify a name for the project. The system also automatically creates a Logstore for the project. If you select Existing Log Service Project, you must select an existing project from the Project Name drop-down list. For more information about how to create a project in Simple Log Service, see Getting Started. Note After you create a trail to deliver events to Simple Log Service, a Logstore whose name is in the actiontrail_<Trail name> format is automatically created and optimally configured for subsequent auditing. Indexes and a dashboard are created for the Logstore to facilitate event queries. You cannot manually write data to the Logstore. This ensures data accuracy. You do not need to create a Logstore in advance.

       • If you select Delivery to Another Account, configure the Project ARN and RAM Role ARN of Destination Account parameters.

         To deliver events to a different account, you must create a RAM role by using the destination account, grant ActionTrail the permissions to deliver events to the destination account, and then create a project before you create the trail. For more information, see Deliver the events of multiple Alibaba Cloud accounts to one account.

     • Select Delivery to OSS.

       • If you select Delivery to Current Account, configure the parameters that are described in the following table.

         Parameter	Description
         OSS Bucket	The bucket to which you want to deliver events. New OSS Bucket Existing OSS Bucket
         Bucket Name	The name of the OSS bucket. The bucket name must be unique within the current Alibaba Cloud account. If you select New OSS Bucket, you must enter an OSS bucket name. ActionTrail creates an OSS bucket with the name that you enter. If you select Existing OSS Bucket, you must select an existing bucket from the Bucket Name drop-down list. For more information about how to create a bucket in OSS, see Create a bucket. Important You must complete real-name registration on the Real-name Registration page before you create a bucket in a region within the Chinese mainland.
         Log File Prefix	The prefix of the names of the log files in which the delivered events are stored. The prefix helps you find the events in subsequent operations.
         Server Encryption	Specifies whether and how to encrypt the log files in the OSS bucket. If you select New OSS Bucket, you must configure this parameter. Valid values: Fully Managed by OSS: The keys managed by OSS are used to encrypt objects in the bucket. OSS uses data keys to encrypt objects. In addition, OSS uses regularly rotated master keys to encrypt data keys. KMS: Key Management Service (KMS) is used to encrypt data. Before you can use KMS keys, you must activate KMS. For more information, see Purchase and enable a KMS instance. Disable: Disable server-side encryption.
         Retention Policy	Specifies whether to enable retention policies. OSS supports WORM-compliant storage. After a retention policy is configured for a bucket, objects stored inside the bucket cannot be deleted or modified during the retention period. Valid values: Disable (default) Enable

       • If you select Delivery to Another Account, configure the RAM Role ARN of OSS Bucket, Bucket Name, and Log File Prefix parameters.

         To deliver events to a different account, you must create a RAM role by using the destination account, grant ActionTrail the permissions to deliver events to the destination account, and then create an OSS bucket before you create the trail. For more information, see Deliver the events of multiple Alibaba Cloud accounts to one account.

     • Select Delivery to MaxCompute.

       • If you select Delivery to Current Account, configure the parameters that are described in the following table.

         Parameter	Description
         MaxCompute Region	The region of the MaxCompute project to which you want to deliver events. Note ActionTrail delivers audit logs to the actiontrail_<Alibaba Cloud account ID> project in the specified region. The names and IDs of MaxCompute projects are unique. If the actiontrail_<Alibaba Cloud account ID> project exists in the current account, ActionTrail delivers audit logs to the existing project by default.
         Project Quota	The quota provided for computing jobs. Note When you create a trail to deliver events to MaxCompute for the first time, you must select a quota. If no quota is available in the current region, select another region.

       • If you select Delivery to Another Account, configure the Project ARN and RAM Role ARN of MaxCompute parameters.

         To deliver events to a different account, you must create a RAM role by using the destination account, grant ActionTrail the permissions to deliver events to the destination account, and then create a MaxCompute project before you create the trail. For more information, see Deliver the events of multiple Alibaba Cloud accounts to one account.
