What are AWS logging best practices?

We recommend customers follow AWS best practices regarding logging which includes the following:

• Ensure CloudTrail is enabled in all regions
• Ensure CloudTrail log file validation is enabled
• Ensure the S3 bucket used to store CloudTrail logs is not publicly accessible
• Ensure CloudTrail trails are integrated with CloudWatch Logs
• Ensure AWS Config is enabled in all regions
• Ensure S3 bucket access logging is enabled on the CloudTrail S3 bucket
• Ensure CloudTrail logs are encrypted at rest using KMS CMKs
• Ensure rotation for customer created CMKs is enabled
• Ensure VPC flow logging is enabled in all VPCs
