<P>PROBLEM TO BE SOLVED: To provide a technology for properly checking syntax of a script contained in communication data. <P>SOLUTION: A communication control device 10 comprises a first database 50 in which a script based on a standard script is made to correspond to a non-standard script corresponding to the script, which is stored; a position detecting circuit 32 which extracts the data of specified length which is to be compared from a specified position of an acquired packet so that the script stored in a payload is contained; a mask circuit 380 which masks the data other than script among the extracted data to be compared; a retrieving circuit 30 which retrieves a script contained in the masked data to be compared from the first database 50; and a process performing circuit 40 which refers to the first database 50, and if the script is a non-standard one, converts it to the one compliant with the standard syntax corresponding to the script, for outputting a packet. <P>COPYRIGHT: (C)2009,JPO&INPIT |
