API Gateway Missing Rate Limiting and Throttling Controls Affecting API Gateway (REST APIs) service in AWS
CCSS (Common Configuration Scoring System) is a set of measures used to determine the severity of the rule.
Each rule is associated with a high-level category. For example IAM, Container, Monitoring, Logging, Network, etc.

Description
Absence of rate limiting and throttling on API Gateway allows unrestricted request rates, potentially leading to denial of service or resource exhaustion. Implementing these controls helps to mitigate abusive behaviors and ensures fair usage by enforcing request quotas and limits.
How to fix?
Set the throttle_settings and api_stages.throttle attributes in the aws_api_gateway_usage_plan resource.
Example Configuration
resource "aws_api_gateway_usage_plan" "usage_plan_754" {
name = "UsagePlan754"
api_stages {
api_id = aws_api_gateway_rest_api.api754.id
stage = aws_api_gateway_stage.stage754.stage_name
throttle {
path = "/path1/GET"
burst_limit = 5
rate_limit = 10
}
}
throttle_settings {
burst_limit = 5
rate_limit = 10
}
}
