AWS Cross-account Role Setup
Alert Logic supports Amazon Web Services (AWS) cross-account roles. The Deployments page in the Alert Logic console allows you to create deployments for your AWS accounts. On this page, you can edit an AWS deployment name, add and edit AWS credentials to provide Alert Logic with cross-account access to those accounts, and delete deployments. For more information about deployments, see About Alert Logic Deployment Types.
Before Alert Logic can manage the protection of your AWS accounts, you must:
- Log into your AWS account to create a cross-account role to allow Alert Logic to access your AWS accounts. To learn how to create a cross-account role, see Create a cross-account access role.
- Log into the Alert Logic console to configure credentials for each discovered AWS deployment.
- Determine whether you want to configure cross-account for centralized CloudTrail log collection. For more information about centralized log collection, see Should you centralize CloudTrail log collection?
The use of centralized CloudTrail log collection affects how you configure cross-account access for your deployment. You should make this decision prior to configuration of your deployment. To learn more about CloudTrail, see About AWS CloudTrail and Alert Logic .
Cross-account roles to allow Alert Logic to access your AWS account. AWS role creation requires that you provide an AWS policy, a document that specifies the permissions assigned to the AWS role you create for Alert Logic to access to your AWS account.
When you create a role to provide Alert Logic cross-account access to your AWS accounts, you provide better protection for those accounts with:
- Improved agent lifecycle management
- Optimized appliance deployments
- Auto-detection of new assets and changed configurations
You can choose from two levels of permissions when you configure your AWS cross-account role:
- (Recommended) Configure AWS Full Permission Deployment—Allows Alert Logic to make all the necessary changes to your AWS account.
- Configure AWS Minimal Permission Deployment—Allows you to maintain full control over the changes in your deployment, and requires you to perform any necessary actions manually.
The full permission policy document does not allow Alert Logic to:
- Retrieve secret keys or credentials from IAM
- Retrieve data from data stores other than S3
- Perform these actions from any other AWS account
- Grant access to the protected account to any other AWS account or user
- Modify IAM credentials or policies
To complete configuration or edit cross-account access in the Alert Logic console, click an AWS deployment tile on the Deployments page, and then provide your AWS role ARN and the External ID.
Periodically, Alert Logic updates the policy documents used for the IAM roles required for AWS deployments. These updates, which Alert Logic announces in Alert Logic Console Release Notes, ensure you can successfully create deployments, and they ensure your existing deployments continue to monitor your AWS assets.
Before you update your IAM roles, download and open the appropriate policy document below. Keep the document open so you can copy and paste information during IAM role creation.
To update an IAM role, see Update an IAM role. Perform this procedure for every IAM role you need to update.
AWS allows you to use a separate, dedicated account with CloudTrail enabled to centralize your CloudTrail log collection, which requires a second IAM role to allow Alert Logic to access the AWS receiving account that collects CloudTrail data.
If you provide cross-account access to the AWS receiving account for centralized log collection, you get near-real-time updates about your assets. Without this cross-account access, the Alert Logic console refreshes information about your assets every 12 hours.
