Trusted Log Management System

Abstract

With the many accounting scandals that have been reported in companies around the world, the need for internal control has steadily grown. Many different kinds of logs exist, and storing them over the long-term is necessary to realize internal control systems based on logs. Previously, we proposed a low-cost system to store logs semi-permanently using a Virtual Large Scale Disk. However, as this log system cannot guarantee the transfer of trusted logs across a vulnerable transfer path, it is unacceptable for use in digital forensics.
