Help AWS Managed Microsoft AD logs

Collecting AWS Managed Microsoft AD logs using AWS Lambda

AWS Managed Microsoft AD makes it easy to extend the existing Active Directory to the AWS Cloud. With this, you can leverage your existing on-premises user credentials to access cloud resources.

Analyzing these security logs will help you keep track of your AD environment and troubleshoot easily. Site24x7 AppLogs uses AWS Lambda to collect AWS Managed Microsoft AD logs from CloudWatch and display the collected information in simple formats like human-readable text or graphs and charts for easy analysis.
