I'm trying to create an AWS Control Tower landing zone for my AWS organization, and am getting a message saying You must unsubscribe your organization from AWS CloudTrail so that AWS Control Tower can proceed. During the setup process, AWS Control Tower creates a new trail in the audit account that's part of your landing zone. How do I do this? Does this mean stopping all CloudTrail trails from sending logs, or is there an organization-wide setting to disable?
AWS Control Tower needs trusted access to be disabled for both Cloudtrail and Config. To disable this you need to login into the Organization management account, and go to AWS Organizations > Services > Disable Config/Cloudtrail.
Trusted access enabled at an Organization level enables these services to inject service roles in all member accounts where they need to change something. Disabling this for Cloudtrail would result in the Organization trail not working anymore, however the master trail would still be intact. All shadow trails in member accounts would be disabled. AWS still allows you to search/filter/download cloudtrail management events in each of the member accounts for last 90 days, just that they wouldn't be transferred to a central s3 bucket for storage.

I'm the administrator of an AWS account that has 4 users. One of the users is racking up higher-than-expected costs.
I checked the Cost Explorer, but could not seem to configure it to view individual users.
As an administrator in AWS, how do I see all of the services this particular user has been using during a given period of time (e.g. the last 12 months)?
Thanks!
AWS resources are associated with an AWS Account, not a specific user.
If a user has the necessary permissions to create resources (eg an Amazon EC2 instance), then the instance is launched in the AWS Account, but there is no link back to the user that requested the resource.
You can, however, use AWS CloudTrail:
AWS CloudTrail is an AWS service that helps you enable operational and risk auditing, governance, and compliance of your AWS account. Actions taken by a user, role, or an AWS service are recorded as events in CloudTrail. Events include actions taken in the AWS Management Console, AWS Command Line Interface, and AWS SDKs and APIs.
It will show all API calls made by the user, including the Action ('launch an EC2 instance'), their IP address, timestamp, etc. Operations in the AWS management console will also be shown, since it makes API calls on behalf of the user.
CloudTrail keeps a history of the past 90 days, but you can create specific 'Trails' that retain data permanently. If you have not done this, then it will not be possible to see what they did prior to 90 days ago.
I wanted to know if there was a way to track alerts or audit anything that happens with the AWS account like who changed what and why. I did find this https://docs.aws.amazon.com/opensearch-service/latest/developerguide/audit-logs.html where they use a comand line for enabling audit logs on an existing domain: aws opensearch update-domain-config --domain-name my-domain --log-publishing-options "AUDIT_LOGS={CloudWatchLogsLogGroupArn=arn:aws:logs:us-east-1:123456789012:log-group:my-log-group,Enabled=true}" but this is in regard to Amazon OpenSearch Service which I believe is only free for 12 months if you haven't used already. AWS Audit Manager. I am aware there are services that can do this but require a fee and I wanted to know if there were any free options
From the AWS documentation:
With AWS CloudTrail, you can monitor your AWS deployments in the cloud by getting a history of AWS API calls for your account, including API calls made by using the AWS Management Console, the AWS SDKs, the command line tools, and higher-level AWS services. You can also identify which users and accounts called AWS APIs for services that support CloudTrail, the source IP address from which the calls were made, and when the calls occurred. You can integrate CloudTrail into applications using the API, automate trail creation for your organization, check the status of your trails, and control how administrators turn CloudTrail logging on and off.
AWS Config provides a detailed view of the resources associated with your AWS account, including how they are configured, how they are related to one another, and how the configurations and their relationships have changed over time.
Basically, AWS CloudTrail keeps a log of API calls (requests to AWS to do/change stuff), while AWS Config tracks how individual configurations have changed over time (for a limited range of resources, such as Security Group rule being changed).
I have enabled an organizational cloudtrail. In each account I can see the events specific for the account which is fine. But also in my management account where I created the organizational trail I only see the events of that account. In the centralized logging bucket I can see log files of each account. Is it possible to see all events of all accounts in my management account? I want to create some eventbridge rules on them, and I prefer to do it in one centralized account then to do it in ever account in the organization.
We have an AWS account with an IAM group, this group contains practically 6 users and most operations in the account are done by this 6 users.
There are 12 Lambda Functions that have been created in the account and there is a particular lambda function (created by one of the 6 users) that I am trying to know who created it (The Lambda function owner).
Please is there a way to do this ?
Resources created in AWS Accounts are associated with the Account, not the IAM User that created the account.
When a user requests AWS to create resources, IAM verifies that the user has permission to create resources. If so, then the resources are created in the Account, but no relationship with the user is kept on that resource.
You can, however, use AWS CloudTrail to view information about the API request that created the resource.
From What Is AWS CloudTrail? - AWS CloudTrail:
AWS CloudTrail is an AWS service that helps you enable governance, compliance, and operational and risk auditing of your AWS account. Actions taken by a user, role, or an AWS service are recorded as events in CloudTrail. Events include actions taken in the AWS Management Console, AWS Command Line Interface, and AWS SDKs and APIs.
How do I find out what IAM user created certain metrics and alarms?
I tried CLI commands: describe-alarms and list-metrics and they don't seem to provide this information nor when looking at the configuration for the alarms and metrics in the AWS console.
While users call APIs to create resources in AWS, those resources are associated with the AWS Account rather than a user. As long as a user has permission to create resources in the account, the resources will be created/viewed/deleted.
However, you can use AWS CloudTrail to retrieve information about the API calls themselves:
AWS CloudTrail is an AWS service that helps you enable governance, compliance, and operational and risk auditing of your AWS account.
