Illegal access to the computer network is one of the serious issues in the present society. Interpolation and deletion of the web files opend on the Internet server are common cases. There are some measures toward those problems. However, they are not perfect because of defects in themselves. And that precautions against illegal access are not enough diffused yet. Alternate measures are desired. Here are some keys to the issues. In order to make the meansures firm, administrators have to investigate log files thoroughly. However, it forces them to continue hard and complivated work. Because the work must be done with the information given only by the character string. The purpose of our reserch is to lighten the hard and complicated word imposed on administrators by visualizing the log files and automating the investigation. Alternate measures against illegal access and interpolation of the web files, such as, detecting the root of illegal access and restoring the web files automatically are introduced in this paper.
