Detecting AWS network ACL activity
You are an Amazon Web Services (AWS) admin who manages access to AWS resources and services across your organization. AWS CloudTrail is an AWS service that helps you enable governance, compliance, and operational/risk auditing of your AWS account. Actions taken by a user, role, or an AWS service are recorded as events in CloudTrail. Part of your role involves monitoring events and actions taken in the AWS Management Console, AWS Command Line Interface, and AWS SDKs and APIs to ensure that your servers are not vulnerable to attacks.
These searches help you to monitor your AWS network infrastructure, using CloudTrail logs from AWS to check for bad configurations and malicious activity in your AWS network access controls.
