GCP Terraform Misconfiguration: Insecure App Engine Domain Transport

Abstract

Terraform 구성이 HTTPS 지원을 설정하지 않고 App Engine 응용 프로그램용 도메인을 설정합니다.

Explanation

기본적으로 App Engine 응용 프로그램용 도메인은 암호화되지 않은 연결과 보안되지 않은 연결을 허용합니다. 이러한 연결로 인해 데이터가 무단 액세스, 도난 및 변조 위험에 노출됩니다.

예제 1: 다음 예제에는 example.com 도메인용 ssl_settings 블록이 포함되지 않은 Terraform 구성이 나와 있습니다. 따라서 App Engine 응용 프로그램용 사용자 지정 도메인이 HTTPS를 지원하지 않습니다.
