PROBLEM TO BE SOLVED: To provide a virus check system allowing a household compact size GW device with a low hardware specification to perform security countermeasures.SOLUTION: In an unauthorized entry preventing system, a GW device performs distribution of pattern files by dividing into pattern files to be stored in the GW device and pattern files to be stored in a terminal device, on the basis of weight information having each pattern file. As a result, the GW device and the terminal device store different pattern files, and respectively performs a virus check on a packet by referring to respective pattern files, thereby allowing distributed processing against a security attack. |
