Abstract: The present invention provides a log file protection system which makes it difficult for computer log information to be altered or deleted. A log information reception process includes receiving log information output from an original application process 210, and storing it in an internal cache 232 in a NIGELOG processing module 230. A hiding directory information gathering process scans a file system 300 to collect information on directories in which hiding is possible. This information constitutes a list of directories 233 in which hiding is possible, and is stored as a variable in the NIGELOG processing module 230. This variable is used by the NIGELOG process whenever files are generated or moved. An alteration detection and log information writing process detects alterations in log files, automatically restores these when alteration is detected, and periodically re-hides log files.

Abstract: A security administration server providing various security services in the LAN and a host server operating in connection thereto are provided. There is installed a security administration server (S) having a function for collecting various log information managed in various devices to be monitored (C) operating in the LAN, a function for generating an image by extracting information useful for security management of the LAN from collected log information and visualizing such information to a form easy for a person to use, and a function for sending the image to another monitoring device (C). Further, the security administration server (S) provides various security services in connection with a host server (H) operating in an external network.
