Allows an assembly to be called by partially trusted code. Without this declaration, only fully trusted callers are able to use the assembly. This class cannot be inherited.

Defines the underlying structure of all code access permissions.

The exception that is thrown when a denied host resource is detected.

Allows the control and customization of security behavior for application domains.

Specifies the security policy components to be used by the host security manager.

Gets an object's System.Security.Policy.Evidence.

Defines methods implemented by permission types.

Defines the methods that convert permission object state to and from XML element representation.

Supports the methods that convert permission object state to and from an XML element representation.

Manages the stack walk that determines whether all callers in the call stack have the required permissions to access a protected resource.

Defines a permission set that has a name and description associated with it. This class cannot be inherited.

Represents a collection that can contain many different types of permissions.

Specifies the type of a managed code policy level.

Represents text that should be kept confidential. The text is encrypted for privacy when being used, and deleted from computer memory when no longer needed. This class cannot be inherited.

Encapsulates and propagates all security-related data for execution contexts transferred across threads. This class cannot be inherited.

Identifies the source for the security context.

Specifies that code or an assembly performs security-critical operations.

Specifies the scope of a System.Security.SecurityCriticalAttribute.

Represents the XML object model for encoding security objects. This class cannot be inherited.

The exception that is thrown when a security error is detected.

Provides the main access point for classes interacting with the security system. This class cannot be inherited.

Indicates the set of security rules the common language runtime should enforce for an assembly.

Identifies the set of security rules the common language runtime should enforce for an assembly.

Identifies types or members as security-critical and safely accessible by transparent code.

Provides a base class for requesting the security status of an action from the AppDomainManager object.

Specifies that an assembly cannot cause an elevation of privilege.

Identifies which of the nonpublic System.Security.SecurityCriticalAttribute members are accessible by transparent code within the assembly.

Defines the integer values corresponding to security zones used by security policy.

Allows managed code to call into unmanaged code without a stack walk. This class cannot be inherited.

Marks modules containing unverifiable code. This class cannot be inherited.

The exception that is thrown when the security policy requires code to be type safe and the verification process is unable to verify that the code is type safe.

The exception that is thrown when there is a syntax error in XML parsing. This class cannot be inherited.
