    • Provided is a system which distributes a processing load of security measures and enforce a security policy to be applicable to a large system. Policy information indicating a security measure to be executed on user information transmitted from a client to a server is stored in a policy storing section. Measure arrangement information indicating the security measure executable in each of a plurality of policy enforcement sections is stored in a measure-arrangement storing section. One or more of the policy enforcement sections are selected on the basis of the policy information and the measure arrangement information. Each of the one or more policy enforcement sections executes the security measure on the user information and outputs, on the basis of a selection result, the user information to the other policy enforcement sections among the one or more policy enforcement sections or to the server.

    • Authentication apparatus authenticates user using host connected to forwarding node. Policy management apparatus holds access control policy for identifying host under access control using identifier of forwarding node or identifier of user, and links identifier of host under access control and identifier of forwarding node to which host is connected, or identifier of host under access control and identifier of user using host. Forwarding node transmits to policy management apparatus identifier of host connected to own forwarding node and identifier of own forwarding node. Authentication apparatus transmits to policy management apparatus identifier of host connected to forwarding node and identifier of user. Policy management apparatus refers to access control policy and, if host connected to forwarding node is under access control, notifies content of access control to control apparatus as access control list. Control apparatus generates processing rule in accordance with access control list and sets generated processing rule in forwarding nodes.
    • 验证设备使用连接到转发节点的主机对用户进行认证。 策略管理装置保存用于使用转发节点的标识符或用户的标识符的标识下的主机访问控制策略,以及主机所连接的主机的接入控制的标识符和主机所连接的转发节点的标识符,以及访问控制下的主机的标识符,以及 使用主机的用户标识符。 转发节点发送到连接到自己的转发节点的主机的策略管理设备标识符和自己的转发节点的标识符。 认证装置向连接到转发节点的主机和用户的标识符的策略管理装置的标识符发送。 策略管理装置是指访问控制策略,如果连接到转发节点的主机正在进行访问控制,则将访问控制的内容通知控制装置作为访问控制列表。 控制装置根据访问控制列表生成处理规则,并在转发节点中设置生成的处理规则。
