EventWaitHandleAuditRule Class

Represents a set of access rights to be audited for a user or group. This class cannot be inherited.

Namespace:  System.Security.AccessControl
Assembly:  mscorlib (in mscorlib.dll)

public sealed class EventWaitHandleAuditRule : AuditRule

The EventWaitHandleAuditRule class is one of a set of classes that the .NET Framework provides for managing Windows access control security on named system events. For an overview of these classes and their relationship to the underlying Windows access control structures, see EventWaitHandleSecurity.

NoteNote:

Windows access control security is meaningful only for named system events. If an EventWaitHandle object represents a local event, access control is irrelevant.

To get a list of the audit rules currently applied to a named event, use the EventWaitHandle.GetAccessControl method to get an EventWaitHandleSecurity object, and then use its GetAuditRules method to obtain a collection of EventWaitHandleAuditRule objects.

EventWaitHandleAuditRule objects do not map one-to-one with access control entries in the underlying discretionary access control list (DACL). When you get the set of all audit rules for an event, the set contains the minimum number of rules currently required to express all the access control entries.

NoteNote:

The underlying access control entries change as you apply and remove rules. The information in rules is merged if possible, to maintain the smallest number of access control entries. Thus, when you read the current list of rules, it might not look exactly like the list of all the rules you have added.

Use EventWaitHandleAuditRule objects to specify access rights to be audited for a user or group. To apply a rule to a named system event, use the EventWaitHandle.GetAccessControl method to get the EventWaitHandleSecurity object. Modify the EventWaitHandleSecurity object by using its methods to add the rule, and then use the EventWaitHandle.SetAccessControl method to reattach the security object.

Important noteImportant Note:

Changes you make to an EventWaitHandleSecurity object do not affect the access levels of the named event until you call the EventWaitHandle.SetAccessControl method to assign the altered security object to the named event.

EventWaitHandleAuditRule objects are immutable. Security for an event is modified using the methods of the EventWaitHandleSecurity class to add or remove rules; as you do this, the underlying access control entries are modified.

NoteNote:

Security on synchronization objects is not supported for Windows 98 or Windows Millennium Edition.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
