Configuring Yandex Query

Audit Trails support is integrated in Yandex Query. You can analyze events of Yandex Cloud resources by executing analytical and streaming YQL queries.

You can execute analytical queries for logs stored in a bucket and streaming queries for logs stored in a Yandex Data Streams data stream.

To connect a bucket with audit logs to Yandex Query and execute YQL queries:

1. Set up your environment.
2. Create a connection between a trail and YQ.
3. Execute a query to logs in Object Storage.

If you no longer need the resources you created, delete them.

Getting startedGetting started

Sign up in Yandex Cloud and create a billing account:

1. Navigate to the management console and log in to Yandex Cloud or register a new account.
2. On the Yandex Cloud Billing page, make sure you have a billing account linked and it has the ACTIVE or TRIAL_ACTIVE status. If you do not have a billing account, create one and link a cloud to it.

If you have an active billing account, you can navigate to the cloud page to create or select a folder for your infrastructure to operate in.

Learn more about clouds and folders.

If you do not have the Yandex Cloud CLI yet, install and initialize it.

Required paid resourcesRequired paid resources

The cost of infrastructure support includes a fee for a bucket (see Pricing for Object Storage).

Assign the audit-trails.viewer and storage.uploader roles to the trail-sa service account:

Assign the bucket-yq-sa service account the storage.viewer role for example-folder:

yc resource-manager folder add-access-binding example-folder \
    --role storage.viewer \
    --subject serviceAccount:<service_account_ID>

A connection must be created only the first time a trail is connected to YQ.

Execute a query to logs in Object StorageExecute a query to logs in Object Storage

Open the page to create an analytical query to Audit Trails logs:

Run event queries to bind audit-trails-logsyq-object_storage:

1. Deleting a folder:

   1. Select this query from the list: 1. Find out who deleted the folder.

   2. Edit the query by specifying the folder ID:

      SELECT * FROM bindings.`audit-trails-logsyq-object_storage`
      WHERE
          JSON_VALUE(data, "$.event_type") = 'yandex.cloud.audit.resourcemanager.DeleteFolder' 
          and JSON_VALUE(data, "$.details.folder_name") = '<folder_ID>' 
          LIMIT 100;
      

   3. Click Execute.

2. Enabling access via the serial console:

   1. Select this query from the list: 6. Changing a VM: Adding serial console access.

   2. Edit the query by specifying the number of displayed records:

      SELECT * FROM bindings.`<audit-trails-logsyq-object_storage>`
      WHERE
          JSON_VALUE(data, "$.event_type") = 'yandex.cloud.audit.compute.UpdateInstance' 
          and JSON_VALUE(data, "$.details.metadata_serial_port_enable") = '1' 
          LIMIT <number_of_records>;
      

   3. Click Execute.

3. Changing access permissions for an Object Storage bucket:

   1. Select this query from the list: 11. Suspicious activity with the Audit Trails log repository (Object Storage bucket).

   2. Edit the query by specifying the number of displayed records:

      SELECT * FROM bindings.`audit-trails-logsyq-object_storage`
      WHERE
          (JSON_VALUE(data, "$.event_type") = 'yandex.cloud.audit.storage.BucketAclUpdate' 
          or JSON_VALUE(data, "$.event_type") = 'yandex.cloud.audit.storage.BucketPolicyUpdate') 
          LIMIT <number_of_records>;
      

   3. Click Execute.

4. Assigning administrator permissions:

   1. Select this query from the list: 20. Assigning admin permissions (for a folder and cloud).

   2. Edit the query by specifying the number of displayed records:

      SELECT * FROM bindings.`audit-trails-logsyq-object_storage`
      WHERE
          JSON_VALUE(data, "$.details.access_binding_deltas.access_binding.role_id") = 'admin' 
          LIMIT <number_of_records>;
      

   3. Click Execute.
