Welcome to this AWS hands-on lab, Setting up Automatic Resource Remediation with AWS Config.
This activity provides you with the opportunity to get hands-on experience creating rules in AWS Config and implementing remediations using Lambda functions. This approach helps maintain a highly-secure networking architecture inside of AWS.
Good luck and enjoy the hands-on lab!
Resources for this activity are on the [Github Repository](https://github.com/julielkinsfembotit/LALabsAWSConfig).
**NOTE**: CloudWatch Events is now EventBridge. You’ll be able to now create rules in Amazon EventBridge Event Rules. We also use a pool of shared AWS accounts for our lab environments. Once the previous user’s lab is terminated, we have a cleaner that reclaims any AWS resources, including EC2 instances, S3 buckets, etc. This prepares the environment for you to use it next. However, because Config uses CloudTrail as the source of its data, and CloudTrail records can’t be deleted, Config sometimes sees resources that no longer exist. To resolve it, we recommend you turn Config off and back on again in Config’s settings. Please see the note on this in the lab instructions to help. Also please note that Config can take a very long time to synchronize, possibly 20 minutes or more.

- Create Lambda Function
- Create Lambda function:
- Click Create Function
- Add name: remediatesg
- Choose Python 3.6, 3.7, or later
- Choose existing IAM role
- Click Create Function
- Delete provided function code
- Use the GitHub link and copy the function code, then paste it into the Lambda console function code box
