Server computer protection apparatus, method, program product, and server computer apparatus

摘要

A server computer protection apparatus for protecting a server computer by allowing only proper access from one or more client computers to reach the server computer. An access request receiving unit receives, in place of the server computer, access requests sent from the client computers. Each received access request is checked by an access request checking unit to determine whether the received access request is proper or not. An access request transfer unit transfers to the server computer 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.
