이 섹션에는 소스 코드 외부에 있지만 제작 중인 제품의 보안에는 여전히 중요한 내용이 모두 포함되어 있습니다. 이 섹션에서 다루는 문제들은 소스 코드와 직접적으로 관련이 없기 때문에 나머지 섹션과 분리했습니다.

ASP.NET Misconfiguration: Incomplete Certificate Validation

C#/VB.NET/ASP.NET

Abstract

피어 발급 인증서를 허용하면 인증서 확인의 보안 수준이 낮아집니다.

Explanation

프로그램이 3가지 중 하나의 방법으로 X.509 인증서를 확인하도록 구성할 수 있습니다. 기본적으로 인증서는 신뢰할 수 있는 루트 기관에 대한 신뢰 체인을 통해 검증됩니다. ChainTrust라고 하는 이 설정은 인증서가 유효하다는 최대 수준의 보증을 제공합니다. 기본적으로 모든 인증서는 ChainTrust를 사용하여 검증됩니다.

신뢰할 수 있는 루트 기관에서 발급하지 않은 인증서를 사용하려면 PeerTrust 또는 PeerOrChainTrust를 설정하여 피어가 발급한 인증서를 신뢰하도록 프로그램을 구성할 수 있습니다. 이러한 설정은 인증서에서 부여하는 보안 수준을 크게 낮추기 때문에 운영 환경에서 사용하면 안 됩니다.
