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
Enforce restrictions on AppSync GraphQL API caching to mitigate the risk of unauthorized access to cached data. Properly configuring caching settings can prevent potential exposure of sensitive information and ensure data privacy and integrity. This rule helps protect against data leakage and unauthorized access to cached data in the AWS AppSync service.
How to fix?
Set the api_caching_behavior attribute in aws_appsync_api_cache resource to FULL_REQUEST_CACHING or PER_RESOLVER_CACHING.
Example Configuration
resource "aws_appsync_graphql_api" "api1" {
authentication_type = "API_KEY"
name = "api1"
}
resource "aws_appsync_api_cache" "cache1" {
api_id = aws_appsync_graphql_api.api1.id
api_caching_behavior = "FULL_REQUEST_CACHING"
type = "LARGE"
ttl = 900
}
resource "aws_appsync_graphql_api" "api2" {
authentication_type = "API_KEY"
name = "api2"
}
resource "aws_appsync_api_cache" "cache2" {
api_id = aws_appsync_graphql_api.api2.id
api_caching_behavior = "PER_RESOLVER_CACHING"
type = "LARGE"
ttl = 900
}
