CloudTrail in AWS is indispensable for maintaining the security and integrity of S3 buckets. By logging all API calls and actions taken within AWS, CloudTrail provides a detailed trail of events, offering crucial visibility into who accessed the S3 buckets, what actions were performed, and when they occurred.
This capability is essential for detecting unauthorized access, identifying security breaches, and investigating any operational issues promptly. In essence, CloudTrail acts as a vigilant watchdog, ensuring that any anomalies or suspicious activities within S3 buckets are promptly flagged and addressed, thereby enhancing overall cloud security posture.
It is important to use monitoring tool in real-world scenarios for production workload. In Real-world scenario, security company having complex AWS infrastructure with multiple services running. Recently, they noticed an unexpected change in their S3 bucket policy, which has led to unauthorized access to sensitive data.
Unauthorized changes in AWS resources can lead to security vulnerabilities, data breaches, and compliance issues. I have used cloud trail to perform RCA, identify issue and deploy elegant solution to increase overall production efficiency.
Amazon S3 buckets are fundamental to AWS’s cloud storage ecosystem, offering unparalleled scalability, durability, and security for storing and retrieving data. With 99.999999999% durability and 99.99% availability, S3 ensures that data remains highly accessible and resilient across multiple Availability Zones within a region.
I have created cloud trail with S3 full access policy to enable monitoring for current S3 bucket. While performing RCA, cloud trail event history highlighted potential issue with put action on AWS S3 public access. Based on the Cloud Trail insights I have made changes to S3 public access configuration to mitigate production issue.
