The access control unit (32), when receiving an access request from any one of the plurality of functional modules (23-26), determines, on the basis of an acceptance policy, whether or not access to the request destination interface from the request source module is accepted, and transmits the access request to the request destination interface when access is accepted. The acknowledgement policy is set using a provision level, which is a security level that is secured by the request source module and that represents security of the function, and a request level, which is a security level requested by the request destination interface to the request source module.
访问控制部(32)若从多个功能模块(23~26)中的任一个功能模块受理访问请求,则根据认可策略,判定是否认可从请求源模块对请求目的地接口的访问,在认可访问的情况下,将访问请求传递给请求目的地接口。使用提供水准和请求水准来设定认可策略,所述提供水准是由请求源模块保证的表示功能的安全性的安全水准,所述请求水准是请求目的地接口对请求源模块请求的安全水准。
