Monitoring API calls by AWS accounts using AWS CloudTrail logging - Amazon CodeCatalyst

Monitoring API calls by AWS accounts using AWS CloudTrail logging

Amazon CodeCatalyst is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service. CloudTrail captures API calls made on behalf of CodeCatalyst in connected AWS accounts as events. If you create a trail, you can enable continuous delivery of CloudTrail events to an S3 bucket, including events for CodeCatalyst. If you don't configure a trail, you can still view the most recent events in the CloudTrail console in Event history.

CodeCatalyst supports logging the following actions as events in CloudTrail log files:

Important

While multiple accounts can be associated with a space, CloudTrail logging for events in CodeCatalyst spaces and projects apply only for the billing account.

The space billing account is your AWS account that is charged for CodeCatalyst resources beyond the AWS Free tier. Multiple accounts can be connected to a space, while only one account can be the designated billing account. The billing account or additional connected accounts for the space can have IAM roles that are used for deploying AWS resources and infrastructure, such as an Amazon ECS cluster or S3 bucket, from CodeCatalyst workflows. You can use the workflow YAML to identify the AWS account that you deployed to.

Note

AWS resources that are deployed into connected accounts for CodeCatalyst workflows, are not logged as part of CloudTrail logging for the CodeCatalyst space. For example, CodeCatalyst resources include a space or project. AWS resources include an Amazon ECS service or Lambda function. CloudTrail logging must be configured separately for each AWS account where resources are deployed into.

CodeCatalyst logging in connected accounts includes the following considerations:

  • Access to CloudTrail events is managed with IAM in the connected account and not in CodeCatalyst.

  • Third-party connections, such as linking to a GitHub repository, will result in third-party resource names being recorded in CloudTrail logs.

Note

CloudTrail logging for CodeCatalyst events is at the space level and does not isolate events by project boundaries.

For more information about CloudTrail, see the AWS CloudTrail User Guide.

Note

This section describes CloudTrail logging for all events logged in a logged in a CodeCatalyst space and the AWS accounts that are connected to CodeCatalyst. Additionally, to review all events logged in a CodeCatalyst space, you can also use the AWS CLI and the aws codecatalyst list-event-logs command. For more information, see Accessing logged events using event logging.

CodeCatalyst space events

Actions in CodeCatalyst for managing space-level and project-level resources are logged in the billing account for the space. For CloudTrail logging for a CodeCatalyst space, events are logged with the following considerations.

  • CloudTrail events apply across the entire space and are not scoped to any single project.

  • When you connect an AWS account to a CodeCatalyst space, loggable events for account connections will be logged in that AWS account. After you enable this connection, you cannot disable it.

  • When you connect an AWS account to a CodeCatalyst space and designate it as the billing account for the space, events will be logged in that AWS account. After you enable this connection, you cannot disable it.

    Events for space-level and project-level resources are logged only in the billing account. To change the CloudTrail destination account, update the billing account in CodeCatalyst. At the beginning of the next monthly billing cycle, the change takes effect for the new billing account in CodeCatalyst. After that, the CloudTrail destination account is updated.

The following are examples of events in AWS that are related to actions in CodeCatalyst for managing space-level and project-level resources. The following APIs are released through the SDK and CLI. Events will be logged in the AWS account specified as the billing account for the CodeCatalyst space.

CodeCatalyst account connections and billing events

The following are examples of events in AWS that are related to actions in CodeCatalyst for account connections or billing:

  • AcceptConnection

  • AssociateIAMRoletoConnection

  • DeleteConnection

  • DissassociateIAMRolefromConnection

  • GetBillingAuthorization

  • GetConnection

  • GetPendingConnection

  • ListConnections

  • ListIAMRolesforConnection

  • PutBillingAuthorization

  • RejectConnection

CodeCatalyst information in CloudTrail

CloudTrail is enabled on an AWS account when you create that account. When you connect that AWS account to a CodeCatalyst space, events for that space that occur in that AWS account are logged in CloudTrail logs in that AWS account. Loggable events in CodeCatalyst are recorded as CloudTrail events in CloudTrail logs in the connected account and in Event history in the CloudTrail console, along with other loggable AWS events in that account.

Every event or log entry contains information about who generated the request. The identity information helps you determine the following:

  • Whether the request was made by a user with their AWS Builder ID.

  • Whether the request was made with root or AWS Identity and Access Management (IAM) user credentials.

  • Whether the request was made with temporary security credentials for a role or federated user.

  • Whether the request was made by another AWS service.

For more information, see the CloudTrail userIdentity element.

Accessing CloudTrail events

For an ongoing record of events in your AWS account, including events for CodeCatalyst activity in the AWS account, create a trail. A trail enables CloudTrail to deliver log files to an S3 bucket. By default, when you create a trail in the console, the trail applies to all AWS Regions. The trail logs events from all Regions in the AWS partition and delivers the log files to the S3 bucket that you specify. Additionally, you can configure other AWS services to further analyze and act upon the event data collected in CloudTrail logs. For more information, see the following:

A trail is a configuration that enables delivery of events as log files to an S3 bucket that you specify. CloudTrail log files contain one or more log entries. An event represents a single request from any source and includes information about the requested action, the date and time of the action, request parameters, and so on. CloudTrail log files aren't an ordered stack trace of the public API calls, so they don't appear in any specific order.

Example CodeCatalyst account connections event in AWS

The following example shows a CloudTrail log entry that demonstrates the ListConnections action. For an AWS account that is connected to the space, ListConnections is used to view all account connections to CodeCatalyst for this AWS account. The event will be logged in the AWS account specified in accountId, and the value of the arn will be the Amazon Resource Name (ARN) of the role used for the action.

Example CodeCatalyst project resource event in AWS

The following example shows a CloudTrail log entry that demonstrates the CreateDevEnvironment action. An AWS account that is connected to the space and is the designated billing account for the space is used for project-level events in the space, such as creating a Dev Environment.

Under userIdentity, in the accountId field, this is the IAM Identity Center account ID (432677196278) that hosts the identity pool for all AWS Builder ID identities. This account ID contains the following information about the CodeCatalyst user for the event.

  • The type field indicates the type of IAM entity for the request. For CodeCatalyst events for space and project resources, this value is IdentityCenterUser. The accountId field specifies the account that owns the entity that was used to get credentials.

  • The userId field contains the AWS Builder ID identifier for the user.

  • The identityStoreArn field contains the role ARN for the identity store account and user.

The recipientAccountId field contains the account ID for the billing account for the space, with an example value here of 111122223333.

For more information, see the CloudTrail userIdentity element.

Note

In certain events, the user agent may not be known. In this case, CodeCatalyst will provide a value of Unknown in the userAgent field in the CloudTrail event.

Querying your CodeCatalyst event trails

You can create and manage queries for your CloudTrail logs using a query table in Amazon Athena. For more information about creating a query, see Querying AWS CloudTrail logs in the Amazon Athena User Guide.
