Cloud Trail can log a variety of events, including:
- Management events: These events are related to the management of your AWS account, such as creating or deleting users, or changing permissions.
- Data events: These events are related to the creation, modification, or deletion of data in your AWS account, such as creating or deleting an S3 bucket, or uploading or downloading an object.
- API events: These events are related to the use of AWS APIs, such as making an API call to create an EC2 instance, or to get the status of an S3 bucket.
Configuring Cloud Trail
Cloud Trail is an essential tool for logging, monitoring, and auditing activities in your AWS account. Configuring Cloud Trail is a straightforward process that can be completed in a few simple steps.
Creating a Cloud Trail Trail
- Open the Cloud Trail console.
- Click on “Create Trail”.
- Enter a name for your trail.
- Select the regions where you want to log events.
- Select the event types that you want to log.
- Choose whether to log data events.
- Configure the storage location for your trail logs.
- Click on “Create Trail”.
Filtering Events Logged by Cloud Trail
Cloud Trail allows you to filter the events that are logged. This can be useful for reducing the amount of data that is stored and for focusing on the events that are most relevant to you.
To filter events, you can use the following options:
- Event type: You can filter events by the type of event, such as API calls, user activity, or resource changes.
- Resource type: You can filter events by the type of resource that was affected, such as EC2 instances, S3 buckets, or IAM users.
- Actor: You can filter events by the user or role that performed the action.
- Time range: You can filter events by the time range in which they occurred.
Analyzing Cloud Trail Logs: On Cloud Trail
Cloud Trail logs provide a wealth of information about the activity within your AWS account. Analyzing these logs can help you troubleshoot issues, track changes to your environment, and meet compliance requirements.There are a number of different tools that you can use to analyze Cloud Trail logs.
The AWS CloudTrail Insights dashboard provides a graphical interface that makes it easy to visualize and analyze your logs. You can also use the AWS CLI or SDK to programmatically access and analyze your logs.Here are a few examples of how you can use Cloud Trail logs to troubleshoot issues:
