설명
이 사용 권한으로 호출 코드가 특정 영역에서 발생되는지 여부를 확인할 수 있습니다. 영역은 Microsoft Internet Explorer 옵션에 따라 구성되며 Internet Explorer의 IInternetSecurityManager 및 관련 API에 의해 URL에서 매핑됩니다. 정확하게 일치하는 영역만 사용 권한에 정의되며, URL은 한 영역에만 속할 수 있습니다.
로컬 인트라넷 영역: 로컬 인트라넷 영역은 회사 인트라넷에 있는 콘텐츠에 사용됩니다. 회사의 방화벽 내부에 서버가 있으므로 인트라넷 상의 콘텐츠에는 높은 수준의 신뢰가 할당됩니다.
신뢰할 수 있는 사이트 영역: 신뢰할 수 있는 사이트 영역은 인터넷의 다른 사이트보다 더 신뢰할 수 있는 웹 사이트의 콘텐츠에 사용됩니다. 사용자는 이 영역을 사용하여 특정 인터넷 사이트에 높은 수준의 신뢰를 할당할 수 있습니다. 신뢰할 수 있는 이러한 웹 사이트의 URL을 사용자가 이 영역으로 매핑해야 합니다. 기본적으로 신뢰할 수 있는 사이트 영역에 있는 사이트는 인터넷 영역에 있는 사이트보다 낮은 수준의 신뢰를 받습니다. 사용자나 회사가 이 영역에 포함된 사이트에 높은 수준의 신뢰를 제공하려면 이 영역에 부여된 신뢰 수준을 변경해야 합니다.
인터넷 영역: 인터넷 영역은 다른 영역에 속하지 않는 인터넷상의 웹 사이트에 사용됩니다. 기본 설정을 사용하면 이러한 사이트에서 다운로드한 코드에서 사용자의 컴퓨터에 있는 리소스에 최소한으로만 액세스할 수 있습니다. 다른 영역에 자동으로 매핑되지 않는 웹 사이트는 이 영역에 속합니다.
제한된 사이트 영역: 제한된 사이트 영역은 다운로드할 때 문제가 발생할 수 있거나 이전에 문제를 발생시킨 콘텐츠가 포함된 웹 사이트에 사용됩니다. 이 영역은 이러한 사이트에서 다운로드한 코드가 사용자의 컴퓨터에서 실행되지 않도록 하는 데 사용할 수 있습니다. 신뢰할 수 없는 이러한 웹 사이트의 URL은 사용자에 의해 이 영역으로 매핑되어야 합니다.
로컬 컴퓨터 영역: 로컬 컴퓨터 영역은 사용자의 컴퓨터에 있는 콘텐츠에 사용되는 암시적 영역입니다. 로컬 시스템에서 Internet Explorer로 캐시되는 콘텐츠 이외에 사용자의 컴퓨터에 있는 콘텐츠는 매우 높은 수준의 신뢰로 처리됩니다.
참고
.NET Framework 버전 1.0 및 1.1에서 ID 권한은 Unrestricted 권한 상태 값을 가질 수 없습니다. .NET Framework 버전 2.0에서 ID 권한은 모든 권한 상태 값을 가질 수 있습니다. 즉, 버전 2.0에서 ID 권한의 동작은 IUnrestrictedPermission 인터페이스를 구현하는 권한의 동작과 같습니다. 버전 1.1 CAS 정책을 사용하여 버전 2.0 응용 프로그램을 실행하는 데 대한 자세한 내용은 <legacyV1CASPolicy> 요소를 참조하십시오.
