소프트웨어 보안은 보안 소프트웨어가 아닙니다. 여기서는 인증, 액세스 제어, 기밀성, 암호화, 권한 관리 등의 항목에 대해 설명합니다.

ASP.NET Misconfiguration: Logging Sensitive Information

Abstract
잘못 구성된 W3Clogger 미들웨어로 인해 중요한 정보가 로깅될 수 있습니다.
Explanation
개인 정보, 시스템 정보 등의 중요한 데이터 로깅을 허용하도록 ASP.NET W3Clogger.loggingFields를 구성할 수 있습니다.
이 데이터에는 HTTP 요청 및 HTTP 응답과 관련된 중요한 정보(예: 클라이언트/서버 IP, 서버 포트, 헤더 크키, 서버에 액세스한 인증된 사용자 이름)가 포함될 수 있습니다.
데이터 보안이 위반되면 공격자가 이 정보를 사용하여 다음과 같은 작업을 수행할 수 있습니다.
- 중요한 정보 도용 또는 권한 수준이 더 높은 사용자 가장
- 내부 서버 검색 및 제한된 리소스 무단 액세스 권한 확보
- 탐지된 서버를 대상으로 보고된 알려진 취약점 악용에 주력하는 공격 진행
예제 1: 다음 코드는 확인이 비활성화된 컨트롤러의 작업 메서드를 보여줍니다.

builder.Services.AddW3CLogging(logging =>
logging.LoggingFields = W3CLoggingFields.All;
... )
Example 1All 플래그를 사용해 ClientIpAddress, ServerName, ServerIpAddress, ServerPort, UserName, Cookie 등의 중요한 데이터를 비롯하여 Http 요청에 포함될 수 있는 모든 필드를 로깅하도록 W3Clogging을 구성하는 방법을 보여줍니다.
