To increase security when a communication system of a communication operator communicates to and from a server at a site, the communication system executes an application process in an intermediate segment (Step S), executes a signal process of acquiring upstream data from a signal from a communication terminal via a site antenna (Step S), executes a relay process of relaying communication between the communication terminal and the application process in an internal network which is communicable to and from a core network system (Step S), detects an anomaly in communication between the internal network and the intermediate segment (Step S), and manages the signal process, the relay process, and a virtual process unit of the application process under the control of the communication operator (Step S).
