<p>Provided are: an information control server that functions as a complete physical barrier and is favorable as a security measure such as for preventing information leakage to an open network such as the internet from a closed network such as a LAN; and an information control method. By means of providing an information leakage prevention server (information control server), of which a recording device that records a firewall program is caused to be write protected and implemented as ROM, between the closed network such as a LAN and the open network such as the internet, the information leakage prevention server can reliably control the relay of information transmitted/received between the closed network such as a LAN and the open network such as the internet without the firewall program being rewritten by a virus attack, and so can function as a physical barrier to information leakage and the like.</p> |
