Managing Regions in Security Lake

Amazon Security Lake can collect security logs and events across AWS Regions in which you've enabled the service. For each Region, your data is stored in a different Amazon S3 bucket. You can specify different data lake configurations (for example, different sources and retention settings) for different Regions. You can also define one or more rollup Regions to consolidate data from multiple Regions.

Checking Region status

Security Lake can collect data across multiple AWS Regions. To track the state of your data lake, it can be helpful to understand how each Region is currently configured. Choose your preferred access method, and follow these steps to get the current status of a Region.

Console
To check Region status

  1. Open the Security Lake console at https://console.aws.amazon.com/securitylake/.

  2. In the navigation pane, choose Regions. The Regions page appears, providing an overview of the Regions in which Security Lake is currently enabled.

  3. Select a Region, and then choose Edit to see details for that Region.

API

To get the status of log collection in the current Region, use the GetDataLakeSources operation of the Security Lake API. If you're using the AWS CLI, run the get-data-lake-sources command. For the accounts parameter, specify one or more AWS account IDs as a list. If your request succeeds, Security Lake returns a snapshot for those accounts in the current Region, including which AWS sources Security Lake is collecting data from and the status of each source. If you don't include the accounts parameter, the response includes the status of log collection for all accounts in which Security Lake is configured in the current Region.

For example, the following AWS CLI command retrieves log collection status for the specified accounts in the current Region. This example is formatted for Linux, macOS, or Unix, and it uses the backslash (\) line-continuation character to improve readability.

$ aws securitylake get-data-lake-sources \
--accounts "123456789012" "111122223333"

The following AWS CLI command lists log collection status for all accounts and enabled sources in the specified Region. This example is formatted for Linux, macOS, or Unix, and it uses the backslash (\) line-continuation character to improve readability.

$ aws securitylake get-data-lake-sources \
--regions "us-east-1" \
--query 'dataLakeSources[].[account,sourceName]'

To determine whether you've enabled Security Lake for a Region, use the ListDataLakes operation. If you're using the AWS CLI, run the list-data-lakes command. For the regions parameter, specify the Region code for the Region—for example, us-east-1 for the US East (N. Virginia) Region. For a list of Region codes, see Amazon Security Lake endpoints in the AWS General Reference. The ListDataLakes operation returns the data lake configuration settings for each Region that you specify in your request. If you don't specify a Region, Security Lake returns the status and configuration settings of your data lake in each Region in which Security Lake is available.

For example, the following AWS CLI command shows the status and configuration settings of your data lake in the eu-central-1 Region. This example is formatted for Linux, macOS, or Unix, and it uses the backslash (\) line-continuation character to improve readability.

$ aws securitylake list-data-lakes \
--regions "us-east-1" "eu-central-1"

Changing Region settings

Choose your preferred method, and follow these instructions to update settings for your data lake in one or more AWS Regions.

Console

  1. Open the Security Lake console at https://console.aws.amazon.com/securitylake/.

  2. In the navigation pane, choose Regions.

  3. Select a Region, and then choose Edit.

  4. Select the check box for Override sources for all accounts in <Region> to confirm that your selections here override previous selections for this Region.

  5. For Select storage classes, choose Add transition to add new storage classes for your data.

  6. For Tags, optionally assign or edit the tags for the Region. A tag is a label that you can define and assign to certain types of AWS resources, including the data lake configuration for your AWS account in a particular Region. To learn more, see Tagging Security Lake resources.

  7. To turn a Region into a rollup Region, choose Rollup Regions (under Settings) in the navigation pane. Then choose Modify. In the Select rollup Regions section, choose Add rollup Region. Select the contributing Regions, and provide Security Lake with permission to replicate data across multiple Regions. When you finish, choose Save to save your changes.

API

To update Region settings for your data lake programmatically, use the UpdateDataLake operation of the Security Lake API. If you're using the AWS CLI, run the update-data-lake command. For the region parameter, specify the Region code for the Region that you want to change the settings for—for example, us-east-1 for the US East (N. Virginia) Region. For a list of Region codes, see Amazon Security Lake endpoints in the AWS General Reference.

Use additional parameters to specify a new value for each setting that you want to change—for example, the encryption key (encryptionConfiguration) and retention settings (lifecycleConfiguration).

For example, the following AWS CLI command updates the data expiration and storage class transition settings for the us-east-1 Region. This example is formatted for Linux, macOS, or Unix, and it uses the backslash (\) line-continuation character to improve readability.

$ update-data-lake \
--configurations '[{"region":"us-east-1","lifecycleConfiguration": {"expiration":{"days":500},"transitions":[{"days":45,"storageClass":"ONEZONE_IA"}]}}]'
