AccessControlList 类

定义

包含一个访问控制项列表,这些项为一个或多个受信者指定访问权限。Contains a list of access control entries, specifying access rights for one or more trustees.

注解

AccessControlList在设置权限时,使用类指定多个受信者和要添加单个调用的访问权限。Use the AccessControlList class to specify multiple trustees and access rights to add with a single call when setting permissions. 通过为每个受信者和访问权限组合添加访问控制项来构造访问控制列表。Construct your access control list by adding an access control entry for each trustee and access rights combination.

AccessControlList标识允许或拒绝其访问安全对象的受信者。A AccessControlList identifies the trustees that are allowed or denied access to a securable object. 当某个进程尝试访问某个安全对象时,系统会检查对象的访问控制列表中的访问控制项,以确定是否授予对该对象的访问权限。When a process tries to access a securable object, the system checks the access control entries in the object's access control list to determine whether to grant access to it. 如果该对象没有访问控制列表,系统将授予所有内容的完全访问权限。If the object does not have an access control list, the system grants full access to everything. 如果对象的访问控制列表没有任何条目,则系统将拒绝所有访问该对象的尝试。If the object's access control list has no entries, the system denies all attempts to access the object.

系统会按顺序检查访问控制项,直到找到允许所有请求的访问权限的一个或多个访问控制项,或者在拒绝任何请求的访问权限之前。The system checks the access control entries in sequence until it finds one or more that allow all the requested access rights or until any of the requested access rights are denied.

系统 AccessControlEntry 会按顺序检查每个事件,直到发生以下事件之一:The system examines each AccessControlEntry in sequence until one of the following events occurs:

  • 拒绝访问会 AccessControlEntry 显式拒绝对线程的访问令牌中列出的某个受信者所请求的任何访问权限。An access-denied AccessControlEntry explicitly denies any of the requested access rights to one of the trustees listed in the thread's access token.

  • 线程的访问令牌中列出的受信者的一个或多个允许访问的 AccessControlEntry 项显式授予所有请求的访问权限。One or more access-allowed AccessControlEntry items for trustees listed in the thread's access token explicitly grant all the requested access rights.

  • AccessControlEntry 检查所有项,但至少有一个请求的访问权限尚未显式允许,在这种情况下,访问将被隐式拒绝。All AccessControlEntry items have been checked and there is still at least one requested access right that has not been explicitly allowed, in which case, access is implicitly denied.
