설명

주의

CAS(코드 액세스 보안)는 .NET Framework 및 .NET의 모든 버전에서 더 이상 사용되지 않습니다. 최신 버전의 .NET은 CAS 주석을 준수하지 않으며 CAS 관련 API를 사용하는 경우 오류가 발생합니다. 개발자는 보안 작업을 수행하는 대체 수단을 찾아야 합니다.

이 특성 호스팅하를 공용 언어 런타임 및 구현 호스트 보호를 SQL Server와 같은 관리 되지 않는 애플리케이션에만 영향을 줍니다. 호스트에서 보호되지 않는 서버나 클라이언트 애플리케이션에서 코드가 실행되면 “evaporates” 특성이 감지되지 않으므로 적용되지 않습니다. 적용되면 보안 작업에서 클래스 또는 메서드가 노출하는 호스트 리소스를 기반으로 링크 요구 사항을 만듭니다.

중요

이 특성은 보안 동작이 아니라 호스트별 프로그래밍 모델 지침을 적용하는 데 사용합니다. 링크 요구 사항을 사용하여 프로그래밍 모델 요구 사항을 만족하는지 확인하지만 HostProtectionAttribute는 보안 권한이 아닙니다.

호스트에 프로그래밍 모델 요구 사항이 없으면 링크 요구가 발생하지 않습니다.

이 특성을 사용하여 다음을 식별합니다.

• 호스트 프로그래밍 모델에 적합하지 않지만 달리 유해하지 않은 메서드 또는 클래스.

• 호스트 프로그래밍 모델에 적합하지 않으며 서버 관리 사용자 코드를 불안정하게 만드는 메서드 또는 클래스.

• 호스트 프로그래밍 모델에 적합하지 않으며 서버 프로세스 자체를 불안정하게 만드는 메서드 또는 클래스.

참고

호스트 보호 환경에서 실행할 수 있는 애플리케이션에서 호출할 클래스 라이브러리를 만드는 경우 HostProtectionResource 리소스 범주를 노출하는 멤버에 이 특성을 적용해야 합니다. 이 특성과 함께 .NET Framework 클래스 라이브러리 멤버를 사용하면 즉각적인 호출자만 검사하게 됩니다. 사용자의 라이브러리 멤버도 이와 동일한 방식으로 즉각적인 호출자 검사만 수행해야 합니다.

참고

Ngen.exe(네이티브 이미지 생성기)를 사용하여 로 보호HostProtectionAttribute되는 어셈블리의 네이티브 이미지를 만들지 마세요. 완전 신뢰 환경에서 이미지는 에 관계없이 HostProtectionAttribute항상 로드되며 부분 신뢰 환경에서는 이미지가 로드되지 않습니다.

생성자

HostProtectionAttribute()	사용되지 않음. 기본값을 사용하여 HostProtectionAttribute 클래스의 새 인스턴스를 초기화합니다.
HostProtectionAttribute(SecurityAction)	사용되지 않음. 지정된 HostProtectionAttribute 값을 사용하여 SecurityAction 클래스의 새 인스턴스를 초기화합니다.

SecurityInfrastructure	사용되지 않음. 보안 인프라가 노출되는지 여부를 나타내는 값을 가져오거나 설정합니다.
SelfAffectingProcessMgmt	사용되지 않음. 자체 영향 프로세스 관리가 노출되는지 여부를 나타내는 값을 가져오거나 설정합니다.
