Abstract

A server computer protection apparatus for protecting a server computer (104) by allowing only proper access from one or more client computers (101) to reach the server computer (104). An access request receiving unit (201) receives, in place of the server computer(104), access requests sent from the client computers (101). The access request is checked by an access request checking unit (202) to determine whether each received access request is proper or not. An access request transfer unit (203) transfers to the server computer(104) only the access request that is determined as proper, while preventing other access requests that are determined as improper from transferring to the server computer (104).
