Provider	AWS
Severity	LOW
Framework	CloudFormation, Serverless

Impact

Enabling access logging for API Gateway V2 (including both HTTP APIs and WebSocket APIs) is critical for monitoring and auditing API usage. Access logging provides detailed records of requests sent to your API, including requester IP, requested paths, response status, and latency. This information is invaluable for troubleshooting, understanding API usage patterns, and identifying potential security threats. This rule ensures that access logging is configured for API Gateway V2 stages, thereby enhancing the observability and security of your API infrastructure.

How to Fix

Resources:* AWS::ApiGatewayV2::Stage, AWS::Serverless::HttpApi Logging Configuration: Ensure the AccessLogSettings property specifies a DestinationArn for storing access logs.

This configuration snippet demonstrates how to enable access logging for an API Gateway V2 stage by specifying a destination ARN for the logs, following best practices for API management and security. [source,go]

Resources: MyHttpApi: Type: AWS::ApiGatewayV2::Stage Properties: ApiId: !Ref MyApi StageName: 'prod' AccessLogSettings:

• DestinationArn: !GetAtt MyLogGroup.Arn Format: '{"requestId":"$context.requestId", "ip":"$context.identity.sourceIp", "requestTime":"$context.requestTime", "httpMethod":"$context.httpMethod", "routeKey":"$context.routeKey", "status":"$context.status", "protocol":"$context.protocol", "responseLength":"$context.responseLength"}' MyLogGroup: Type: AWS::Logs::LogGroup Properties: LogGroupName: /aws/apigateway/myhttpapi/logs RetentionInDays: 365
