Design and implementation of file access control module for multi user operating system using on windows

With the rapid development of information sharing through network, IT system is exposed to various threat and security incident are became a social problem. As a countermeasure, various security systems are been using such as IDS, Firewall, VPN etc. But, expertise or expert is required to handle these security systems, so it is not easy for ordinary users to operate them. This paper has developed the design and implementation of file access control module for secure operating system which can exclude from attacks on the operating system rather than detection of attacks. The module implemented in this paper is based on Windows and has effect on access control, integrity and non-repudiation for a file with an access control over files on the Windows based OS that are used by multi-user.
