Alert Logic Log Manager for Amazon Web Services CloudTrail

Before you begin

Before you configure CloudTrail for Log Manager, you must create an Amazon Web Services Cloud Defender deployment and configure cross-account role access for the deployment. To create a Cloud Defender deployment, see Create a deployment. For information about cross-account role access, see Configure Alert Logic AWS Cross-account Role Access.

Create an SQS queue

The SQS queue informs Alert Logic Log Manager of log messages to collect. Log Manager automatically queries this SQS queue and retrieves the CloudTrail log message from the queue. Alert Logic stores the CloudTrail log message in accordance with your log retention period, and you can query it from the Alert Logic console.

This SQS queue is in addition to the default SQS queue (which has a name that starts with outcomesbucket) created with your deployment.

To create an SQS queue: 

  1. In the AWS console, under Application Integration, click SQS.
  2. Click Create New Queue.
  3. In Queue Name, type a descriptive name, and then copy that name. You will need this information later to complete the CloudTrail configuration process.
  4. Keep the default configurations and click Create Queue.
  5. Select the check box next to the newly created queue, and then select Subscribe Queue to SNS Topic from the drop-down menu.
  6. In Choose a Topic, select the SNS topic used by your CloudTrail.
  7. Click Subscribe.
  8. To confirm successful configuration, click OK.
  9. Copy the Amazon Resource Name (ARN) for the queue. You will need this information later to complete the configuration process in the Alert Logic console.

Create an IAM policy and role for cross-account access

To provide Alert Logic with cross-account access to your AWS account and the resources necessary to perform this configuration, you must create an IAM policy and role in the AWS console.

Download and open this policy document. Make the following changes to the policy document:

  1. Replace <ARN_FOR_SQS_QUEUE> with the ARN you copied earlier.
  2. Replace <CLOUDTRAIL_S3_BUCKET_NAME> with the S3 bucket name used by your CloudTrail.

Keep the policy document open so you can copy and paste the information during IAM role creation.

Do not use this policy document if you want to encrypt your CloudTrail logs with AWS Key Management Service (KMS).

To create a cross-account access role:

  1. In the AWS Console, click IAM, located under Security, Identity & Compliance.
  2. From the IAM Management Console, click Policies, and then click Create Policy.
  3. Click the JSON tab.
  4. Copy and paste the contents of your policy document into the JSON window.
  5. Click Review policy.
  6. On the Review Policy page, type a Policy Name and Description for the policy.
  7. Click Create policy.
  8. From the IAM Management Console, click Roles, and then click Create role.
  9. On the Create role page, click Another AWS account.
  10. Enter the following information for Alert Logic:
    • Account ID—Type 239734009475
    • Select Require external ID.
    • External ID—Use your Alert Logic Customer ID. To find your Customer ID, in the Alert Logic console, click Settings () > Support Information.
    • Require MFA—make sure the option is not selected.
  11. Click Next: Permissions.
  12. Select the policy you created above, and then click Next: Review.
  13. Type a Role Name and Role description, and then click Create Role.
  14. In the list of IAM roles, click the name of the role you created, and then note the Role ARN value, which you will need when you create the AWS credentials in the Alert Logic console.
