AWS CloudTrail aids in enabling governance, compliance, and operational and risk auditing for your AWS account. Events in CloudTrail are actions made by a role, user, or AWS service. AWS Management Console, AWS Command Line Interface, and AWS SDKs and APIs are examples of events.
When you create CloudTrail, it is already active in your AWS account and doesn’t need to be manually configured. Every action you do within your AWS account is documented as a CloudTrail event.
There are three ways to record events using CloudTrail:
Event history: An AWS Region’s Event history offers a viewable, searchable, printable, and unchangeable record of all management events that have occurred during the last ninety days. Events can be found by applying a single attribute filter. When you first create your account, you are immediately granted access to the Event history. The Event history can be viewed without paying any fees with CloudTrail.
CloudTrail Lake: AWS’s CloudTrail Lake For audit and security purposes, CloudTrail Lake is a managed data lake that records, stores, retrieves, and analyses user and API activity on AWS. Existing events in row-based JSON format are converted to Apache ORC format by CloudTrail Lake. The columnar storage format known as ORC is designed to facilitate quick data retrieval. Using sophisticated event selectors, you may create immutable collections of events based on certain criteria, which are then combined into event data stores.
An event data storage allows you to retain the event data for a maximum of seven years, or 2557 days. Using AWS Organisations, you may construct an event data store for a single AWS account or for several AWS accounts. Any CloudTrail logs that are currently stored in your S3 buckets can be imported into a new or existing event data store. You can also see the most popular CloudTrail event trends with Lake dashboards.
With CloudTrail Lake, the monthly billing amount is determined by the quantity of uncompressed data ingested; ingestion and storage are billed jointly.
Trails: Trails record and store AWS activity in an Amazon S3 bucket. They can also send the recorded events to Amazon CloudWatch Logs and Amazon EventBridge. These occurrences can be entered into your security monitoring solutions. To search and examine your CloudTrail logs, you can also leverage third-party solutions, such as Amazon Athena or your own. Using AWS Organisations, you may make trails for a single AWS account or several AWS accounts. You can log Insights events and examine your management events to look for unusual patterns in the volume of API calls and error rates.

- Accountability: CloudTrail makes users accountable for their actions, as every operation is logged. This transparency encourages responsible behavior and helps to identify users responsible for specific actions.
- Real-Time Monitoring: CloudTrail can be integrated with Amazon CloudWatch, allowing you to set up real-time monitoring and receive alerts based on specific events and metrics. This enables proactive responses to security incidents.
- Multi-Region Support: Organizations with a global presence can benefit from CloudTrail’s multi-region support, which allows you to monitor and audit activities across different AWS regions.
- Customization: You can tailor CloudTrail to log only specific AWS services, actions, or resources, reducing noise in your logs and focusing on the events most relevant to your use case.
- Integration: CloudTrail seamlessly integrates with other AWS services like AWS Lambda, which enables automated responses to security events, and AWS Config, which enhances governance and compliance monitoring.
- Data Validation: CloudTrail logs are cryptographically signed and can be configured for log file integrity validation, ensuring the authenticity and non-tampering of log data.
- Cost-Effective: The cost of AWS CloudTrail is often affordable, and by preventing any security breaches and expediting compliance procedures, it can save businesses money.
AWS CloudTrail pricing varies depending on the number of recorded events, data storage in Amazon S3, data transfer, custom event triggers, CloudWatch Logs integration, and other factors. CloudTrail offers a certain number of free events each month, with additional charges based on the volume of recorded events beyond that limit. Storing logs in S3 incurs storage costs, and data transfer costs may apply when moving logs to different AWS regions or outside of AWS. Custom event triggers and features like CloudTrail Insights can also lead to additional charges.
