System.Security.AccessControl Namespace

Provides programming elements that control access to and audit security-related actions on securable objects.

Classes

AccessRule	Represents a combination of a user's identity, an access mask, and an access control type (allow or deny). An AccessRule object also contains information about how the rule is inherited by child objects and how that inheritance is propagated.
AccessRule<T>	Represents a combination of a user's identity, an access mask, and an access control type (allow or deny). An AccessRule`1 object also contains information about the how the rule is inherited by child objects and how that inheritance is propagated.
AceEnumerator	Provides the ability to iterate through the access control entries (ACEs) in an access control list (ACL).
AuditRule	Represents a combination of a user's identity and an access mask. An AuditRule object also contains information about how the rule is inherited by child objects, how that inheritance is propagated, and for what conditions it is audited.
AuditRule<T>	Represents a combination of a user's identity and an access mask.
AuthorizationRule	Determines access to securable objects. The derived classes AccessRule and AuditRule offer specializations for access and audit functionality.
AuthorizationRuleCollection	Represents a collection of AuthorizationRule objects.
CommonAce	Represents an access control entry (ACE).
CommonAcl	Represents an access control list (ACL) and is the base class for the DiscretionaryAcl and SystemAcl classes.
CommonObjectSecurity	Controls access to objects without direct manipulation of access control lists (ACLs). This class is the abstract base class for the NativeObjectSecurity class.
CommonSecurityDescriptor	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).
CompoundAce	Represents a compound Access Control Entry (ACE).
CustomAce	Represents an Access Control Entry (ACE) that is not defined by one of the members of the AceType enumeration.
DirectoryObjectSecurity	Provides the ability to control access to directory objects without direct manipulation of Access Control Lists (ACLs).
DirectorySecurity	Represents the access control and audit security for a directory. This class cannot be inherited.
DiscretionaryAcl	Represents a Discretionary Access Control List (DACL).
FileSecurity	Represents the access control and audit security for a file. This class cannot be inherited.
FileSystemAccessRule	Represents an abstraction of an access control entry (ACE) that defines an access rule for a file or directory. This class cannot be inherited.
FileSystemAuditRule	Represents an abstraction of an access control entry (ACE) that defines an audit rule for a file or directory. This class cannot be inherited.
FileSystemSecurity	Represents the access control and audit security for a file or directory.
GenericAce	Represents an Access Control Entry (ACE), and is the base class for all other ACE classes.
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).
KnownAce	Encapsulates all Access Control Entry (ACE) types currently defined by Microsoft Corporation. All KnownAce objects contain a 32-bit access mask and a SecurityIdentifier object.
NativeObjectSecurity	Provides the ability to control access to native objects without direct manipulation of Access Control Lists (ACLs). Native object types are defined by the ResourceType enumeration.
ObjectAccessRule	Represents a combination of a user's identity, an access mask, and an access control type (allow or deny). An ObjectAccessRule object also contains information about the type of object to which the rule applies, the type of child object that can inherit the rule, how the rule is inherited by child objects, and how that inheritance is propagated.
ObjectAce	Controls access to Directory Services objects. This class represents an Access Control Entry (ACE) associated with a directory object.
ObjectAuditRule	Represents a combination of a user's identity, an access mask, and audit conditions. An ObjectAuditRule object also contains information about the type of object to which the rule applies, the type of child object that can inherit the rule, how the rule is inherited by child objects, and how that inheritance is propagated.
ObjectSecurity	Provides the ability to control access to objects without direct manipulation of Access Control Lists (ACLs). This class is the abstract base class for the CommonObjectSecurity and DirectoryObjectSecurity classes.
ObjectSecurity<T>	Provides the ability to control access to objects without direct manipulation of Access Control Lists (ACLs); also grants the ability to type-cast access rights.
PrivilegeNotHeldException	The exception that is thrown when a method in the System.Security.AccessControl namespace attempts to enable a privilege that it does not have.
QualifiedAce	Represents an Access Control Entry (ACE) that contains a qualifier. The qualifier, represented by an AceQualifier object, specifies whether the ACE allows access, denies access, causes system audits, or causes system alarms. The QualifiedAce class is the abstract base class for the CommonAce and ObjectAce classes.
RawAcl	Represents an Access Control List (ACL).
RawSecurityDescriptor	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).
RegistryAccessRule	Represents a set of access rights allowed or denied for a user or group. This class cannot be inherited.
RegistryAuditRule	Represents a set of access rights to be audited for a user or group. This class cannot be inherited.
RegistrySecurity	Represents the Windows access control security for a registry key. This class cannot be inherited.
SystemAcl	Represents a System Access Control List (SACL).

Enums

AccessControlActions	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 descendants.
AccessControlSections	Specifies which sections of a security descriptor to save or load.
AccessControlType	Specifies whether an AccessRule object is used to allow or deny access. These values are not flags, and they cannot be combined.
AceFlags	Specifies the inheritance and auditing behavior of an access control entry (ACE).
AceQualifier	Specifies the function of an access control entry (ACE).
AceType	Defines the available access control entry (ACE) types.
AuditFlags	Specifies the conditions for auditing attempts to access a securable object.
CompoundAceType	Specifies the type of a CompoundAce object.
ControlFlags	These flags affect the security descriptor behavior.
FileSystemRights	Defines the access rights to use when creating access and audit rules.
InheritanceFlags	Inheritance flags specify the semantics of inheritance for access control entries (ACEs).
ObjectAceFlags	Specifies the presence of object types for Access Control Entries (ACEs).
PropagationFlags	Specifies how Access Control Entries (ACEs) are propagated to child objects. These flags are significant only if inheritance flags are present.
RegistryRights	Specifies the access control rights that can be applied to registry objects.
ResourceType	Specifies the defined native object types.
SecurityInfos	Specifies the section of a security descriptor to be queried or set.

Delegates

NativeObjectSecurity.ExceptionFromErrorCode

Provides a way for integrators to map numeric error codes to specific exceptions that they create.
