Well this has surely been a really interesting chapter to cover! Before we move ahead with the next chapter, let's quickly summarize all that we have learned so far!

We started off the chapter with a brief overview of AWS CloudTrail, along with a small step-by-step guide on getting started with your very own CloudTrail Trail. We also learned about AWS CloudTrail Logs, and their integration capabilities with Amazon CloudWatch Logs for better alerting and notifications capabilities. We also leveraged a couple of CloudFormation templates to deploy pre-configured CloudWatch alarms for monitoring our Trail, as well as setting up an entire Amazon Elasticsearch domain for viewing and filtering the CloudTrail Logs. Last, but not least, we also covered AWS Config as a configuration management and compliance service by deploying both managed as well as custom config rules.

In the next chapter, we will be continuing and concluding our security journey with two really amazing services: AWS IAM and AWS Organizations, so stay tuned!
