- Atributos
Campos
| AllFlags | 16383 | Estado no restringido del permiso. |
| Assertion | 1 | Posibilidad de afirmar que todos los llamadores de este código tienen el permiso necesario para la operación. |
| BindingRedirects | 8192 | Permiso para realizar redirección de enlace explícita en el archivo de configuración de la aplicación. Esto incluye la redirección de los ensamblados de .NET que han sido unificados además de otros ensamblados encontrados fuera de .NET. |
| ControlAppDomain | 1024 | Posibilidad de crear y manipular AppDomain. |
| ControlDomainPolicy | 256 | Posibilidad de especificar una directiva de dominio. |
| ControlEvidence | 32 | Posibilidad de proporcionar pruebas, que incluye la posibilidad de modificar las pruebas proporcionadas por Common Language Runtime. Es un permiso eficaz que solo debe concederse al código de plena confianza. |
| ControlPolicy | 64 | Posibilidad de ver y modificar la directiva. Es un permiso eficaz que solo debe concederse al código de plena confianza. |
| ControlPrincipal | 512 | Posibilidad de manipular el objeto de entidad de seguridad. |
| ControlThread | 16 | Posibilidad de utilizar determinadas operaciones avanzadas en subprocesos. |
| Execution | 8 | Permiso para ejecutar el código. Sin este permiso el código administrado no se ejecutará. Esta marca no tiene efecto cuando se usa dinámicamente con modificadores de pila como Deny(), Assert() y PermitOnly(). |
| Infrastructure | 4096 | Permiso para conectar código a la infraestructura de Common Language Runtime, como agregar receptores de contexto de comunicación remota, receptores de envío y receptores dinámicos. |
| NoFlags | 0 | No hay acceso de seguridad. |
| RemotingConfiguration | 2048 | Permiso para configurar canales y tipo de comunicación remota. |
| SerializationFormatter | 128 | Posibilidad de proporcionar servicios de serialización. Utilizado por formateadores de serialización. |
| SkipVerification | 4 | Posibilidad de omitir la comprobación del código en este ensamblado. El código que no se puede comprobar se puede ejecutar si se concede este permiso. Es un permiso eficaz que solo debe concederse al código de plena confianza. Esta marca no tiene efecto cuando se usa dinámicamente con modificadores de pila como Deny(), Assert() y PermitOnly(). |
| UnmanagedCode | 2 | Posibilidad de llamar a código no administrado. Dado que el código no administrado permite potencialmente que se omitan otros permisos, se trata de un permiso peligroso que solo debería concederse a un código de plena confianza. Se utiliza para aplicaciones tales como la llamada a código nativo mediante PInvoke o COM interop. |

Precaución
La seguridad de acceso al código (CAS) ha quedado en desuso en todas las versiones de .NET Framework y .NET. Las versiones recientes de .NET no respetan las anotaciones cas y producen errores si se usan api relacionadas con CAS. Los desarrolladores deben buscar medios alternativos para realizar tareas de seguridad.
Esta enumeración la usa SecurityPermission.
Precaución
Muchas de estas marcas son eficaces y solo se deben conceder al código de alta confianza.
