## **Differences Between AWS Config and CloudTrail**
**1. Purpose and Functionality**

**• AWS Config:** AWS Config is a service that enables you to assess and evaluate the configurations of AWS resources. It continuously monitors resource configurations and records any changes that occur. It provides a detailed inventory of AWS resources and allows you to track configuration changes over time. AWS Config helps ensure compliance with internal policies and external regulations by providing a comprehensive view of resource configurations.

**• AWS CloudTrail:** On the other hand, AWS CloudTrail focuses on providing visibility into user activity by recording API calls made on your AWS account. It captures information such as who made the API call, the services accessed, and the actions performed. CloudTrail logs can be used for resource change tracking, security analysis, and troubleshooting. It helps in understanding the actions taken on AWS resources and aids in security incident response.


## **2. Scope of Monitoring**

**• AWS Config:** AWS Config primarily focuses on monitoring and managing the configurations of AWS resources. It covers a wide array of AWS services, including compute, storage, networking, and security services. AWS Config provides detailed configuration history, configuration snapshots, and configuration change notifications for supported resources.

**• AWS CloudTrail:** AWS CloudTrail, on the other hand, focuses on monitoring API activity within your AWS account. It captures API calls across various AWS services, including but not limited to EC2, IAM, S3, and Lambda. CloudTrail provides a chronological record of API activity, including the identity of the caller, the time of the API call, and the parameters passed.


## **3. Compliance and Security**

**• AWS Config:** AWS Config aids in maintaining compliance by continuously evaluating resource configurations against predefined rules. It allows you to define custom rules based on organizational requirements and regulatory standards. AWS Config also provides a configuration timeline, facilitating the identification and investigation of security incidents or compliance violations.

**• AWS CloudTrail:** AWS CloudTrail contributes to security and compliance efforts by providing a detailed audit trail of user activity within your AWS environment. It helps identify unauthorized access attempts, detect unusual activity patterns, and investigate security breaches. CloudTrail logs can be integrated with Security Information and Event Management (SIEM) systems for real-time analysis and automated alerting.
