System.Security Namespace

Provides the underlying structure of the common language runtime security system, including base classes for permissions.

Classes

AllowPartiallyTrustedCallersAttribute	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.
CodeAccessPermission	Defines the underlying structure of all code access permissions.
HostProtectionException	The exception that is thrown when a denied host resource is detected.
HostSecurityManager	Allows the control and customization of security behavior for application domains.
NamedPermissionSet	Defines a permission set that has a name and description associated with it. This class cannot be inherited.
PermissionSet	Represents a collection that can contain many different types of permissions.
SecureString	Represents text that should be kept confidential, such as by deleting it from computer memory when no longer needed. This class cannot be inherited.
SecureStringMarshal	Provides a collection of methods for allocating unmanaged memory and copying unmanaged memory blocks.
SecurityContext	Encapsulates and propagates all security-related data for execution contexts transferred across threads. This class cannot be inherited.
SecurityCriticalAttribute	Specifies that code or an assembly performs security-critical operations.
SecurityElement	Represents the XML object model for encoding security objects. This class cannot be inherited.
SecurityException	The exception that is thrown when a security error is detected.
SecurityManager	Provides the main access point for classes interacting with the security system. This class cannot be inherited.
SecurityRulesAttribute	Indicates the set of security rules the common language runtime should enforce for an assembly.
SecuritySafeCriticalAttribute	Identifies types or members as security-critical and safely accessible by transparent code.
SecurityState	Provides a base class for requesting the security status of an action from the AppDomainManager object.
SecurityTransparentAttribute	Specifies that an assembly cannot cause an elevation of privilege.
SecurityTreatAsSafeAttribute	Identifies which of the nonpublic SecurityCriticalAttribute members are accessible by transparent code within the assembly.
SuppressUnmanagedCodeSecurityAttribute	Allows managed code to call into unmanaged code without a stack walk. This class cannot be inherited.
UnverifiableCodeAttribute	Marks modules containing unverifiable code. This class cannot be inherited.
VerificationException	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.
XmlSyntaxException	The exception that is thrown when there is a syntax error in XML parsing. This class cannot be inherited.

Interfaces

IEvidenceFactory	Gets an object's Evidence.
IPermission	Defines methods implemented by permission types.
ISecurityEncodable	Defines the methods that convert permission object state to and from XML element representation.
ISecurityPolicyEncodable	Supports the methods that convert permission object state to and from an XML element representation.
IStackWalk	Manages the stack walk that determines whether all callers in the call stack have the required permissions to access a protected resource.

Enums

HostSecurityManagerOptions	Specifies the security policy components to be used by the host security manager.
PartialTrustVisibilityLevel	Specifies the default partial-trust visibility for code that is marked with the AllowPartiallyTrustedCallersAttribute (APTCA) attribute.
PolicyLevelType	Specifies the type of a managed code policy level.
SecurityContextSource	Identifies the source for the security context.
SecurityCriticalScope	Specifies the scope of a SecurityCriticalAttribute.
SecurityRuleSet	Identifies the set of security rules the common language runtime should enforce for an assembly.
SecurityZone	Defines the integer values corresponding to security zones used by security policy.
