API Gateway stages for V1 and V2 should have access logging enabled

Default Severity: medium

Explanation

API Gateway stages should have access log settings block configured to track all access to a particular stage. This should be applied to both v1 and v2 gateway stages.

Possible Impact

Logging provides vital information about access and usage

Suggested Resolution

Enable logging for API Gateway stages

Insecure Example

The following example will fail the aws-api-gateway-enable-access-logging check. 

 resource "aws_apigatewayv2_stage" "bad_example" {
   api_id = aws_apigatewayv2_api.example.id
   name   = "example-stage"
 }

 resource "aws_apigatewayv2_stage" "bad_example" {
   deployment_id = aws_api_gateway_deployment.example.id
   rest_api_id   = aws_api_gateway_rest_api.example.id
   stage_name    = "example"
 }

Secure Example

The following example will pass the aws-api-gateway-enable-access-logging check. 

 resource "aws_apigatewayv2_stage" "good_example" {
   api_id = aws_apigatewayv2_api.example.id
   name   = "example-stage"

   access_log_settings {
    destination_arn = "arn:aws:logs:region:0123456789:log-group:access_logging"
    format          = "json"
   }
 }

 resource "aws_api_gateway_stage" "good_example" {
   deployment_id = aws_api_gateway_deployment.example.id
   rest_api_id   = aws_api_gateway_rest_api.example.id
   stage_name    = "example"

   access_log_settings {
     destination_arn = "arn:aws:logs:region:0123456789:log-group:access_logging"
     format          = "json"
   }
 }
