Activity Monitoring
AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. It records the API calls made for your AWS account within the AWS Management Console, SDKs, command line tools, and other AWS services. This data helps you monitor changes to AWS resources and evaluate security implications. For example, you can identify unauthorized access to your resources and trace back the source API calls. You can also configure CloudTrail to send logged data to Amazon S3 for storage and later analysis or send real-time notifications via Amazon SNS.
Event History
Event history in AWS CloudTrail is a searchable record of the last 90 days of API activity within your AWS account. It provides insights into the management activities performed by users, roles, or services. You can access the event history from the AWS Management Console, AWS CLI, or the CloudTrail API. This data helps you monitor the API activity and changes made to resources in your account. For example, by analyzing the event history, you can detect unusual behavior, troubleshoot resource changes, and identify security issues.
Trail
A trail in AWS CloudTrail is a configuration that enables delivery of event logs to specified Amazon S3 buckets, Amazon CloudWatch Logs log groups, or an Amazon SNS Topic. You can create one or more trails for an AWS account. By enabling trails, you can periodically capture and store the API activity for later review and analysis. A trail also supports log file encryption using AWS Key Management Service (KMS) and allows you to define how long the logs should be stored.
Insight Events
Insight events in AWS CloudTrail are special types of log events that provide deep visibility into potentially anomalous or unusual API activity within your AWS account. These events can help identify security issues, resource changes, and potential threats. Insight events are generated when the rate of occurrence of specific management events exceeds a predefined threshold. By monitoring these events, you can implement timely security measures, prevent data leaks, and better understand the activities taking place within your account.
Log File Validation
Log file validation is a feature in AWS CloudTrail that enables you to verify the integrity of the log files stored in Amazon S3. With this feature, CloudTrail creates a hash of each log entry using a digital signature and adds it to the log file. Later, you can verify the integrity by comparing the locally computed hash and the hash stored in the log files. Log file validation helps ensure that the log files have not been tampered with or modified, providing an additional level of security and compliance for your AWS account activity monitoring.
Management Events
Management events provide insight into the configuration and operational changes within an AWS account, allowing you to track changes made to resources, security groups, and various other entities within your environment. These events include API calls that create, modify, or delete resources in your account, as well as console sign-in events. By monitoring management events, you can ensure compliance with your organization's policies and improve the overall security of your AWS environment. This allows you to fully understand the activity taking place within your account, making it easier to detect unauthorized or abnormal behavior.
Data Events
Data events provide information about resource-level operations performed on or within Amazon S3 and AWS Lambda. They are higher in volume and are typically used for more granular auditing, providing a record of API actions performed on the data plane, such as reading or writing data, and can help ensure that any unauthorized access is detected and addressed. By recording and monitoring data events, you can trace the flow of data through your organization and ensure compliance with data protection regulations, as well as evaluate and analyze the performance of your AWS resources.
Event Filtering
Event filtering in AWS CloudTrail helps you to narrow down the events and resources that you want to monitor by specifying filters that match specific attributes. This enables you to focus only on specific activity types, services, regions, or accounts, reducing the amount of incoming data and, thus, simplifying the process of tracking and analyzing API events. This filtering process ensures that the logs and insights generated are relevant and actionable for your organization, improving the overall efficiency and effectiveness of your monitoring and auditing processes.
Security Management
AWS CloudTrail is an essential tool for creating a foundation of security and visibility within an AWS environment, allowing you to continuously monitor and manage the overall security posture of your resources. It simplifies your compliance auditing by providing an audit trail of all user activity within your account, and helps you to identify and remediate potential security risks. By integrating CloudTrail with other AWS security services, like AWS GuardDuty, AWS Config, and Amazon Macie, you can further enhance the security and compliance capabilities, ensuring that your AWS environment remains secure and aligned with industry best practices.
Integration with AWS Services
AWS CloudTrail seamlessly integrates with many other AWS services, enhancing the effectiveness of your monitoring activities and providing a more comprehensive picture of the interactions between your applications and AWS resources. By combining CloudTrail logs with other AWS services like Amazon S3, Amazon CloudWatch, AWS Lambda, and AWS Glue, you can develop advanced workflows, automate remediation activities, and improve the overall governance of your cloud environment. These integrations help you get better visibility and understanding of your AWS infrastructure, allowing you to optimize your resources and maintain a high level of security and compliance.
