System.Security.AccessControl Namespace

The System.Security.AccessControl namespace provides programming elements that control access to and audit security-related actions on securable objects.

Remarks

 

Classes

TypeReason

Specifies the actions that are permitted for securable objects.

AccessControlModification

Specifies the type of access control modification to perform. This enumeration is used by methods of the ObjectSecurity class and its descendents.

AccessControlType

Specifies whether an AccessRule object is used to allow or deny access. These values are not flags, and they cannot be combined.

AccessRule

GenericAcl

Represents an access control list (ACL) and is the base class for the CommonAcl, DiscretionaryAcl, RawAcl, and SystemAcl classes.

GenericSecurityDescriptor

Represents a security descriptor. A security descriptor includes an owner, a primary group, a Discretionary Access Control List (DACL), and a System Access Control List (SACL).

InheritanceFlags

Inheritance flags specify the semantics of inheritance for access control entries (ACEs).

KnownAce
