Description

Lambda functions should have proper logging permissions to send logs to CloudWatch Logs for monitoring, debugging, and security auditing purposes. This check validates that the execution role has either the AWS managed logging policy or inline permissions for required CloudWatch Logs actions.

Remediation

Attach the AWS managed policy AWSLambdaBasicExecutionRole to the Lambda execution role, or add inline permissions for logs:CreateLogGroup, logs:CreateLogStream, and logs:PutLogEvents. Refer to Sending Lambda function logs to CloudWatch Logs.
