    Recovery Based Architecture To Protect Hids Log Files Using Time Stamps
    (ACADEMY PUBLISHER, 2010) Khurana, Surinder Singh; Bansal, Divya; Sofat, Sanjeev
    After the great revolution in the field of Information Technology, many applications made necessity to run computer systems (either servers or client machines) all the time. Along with improvements and new inventions in technology, the threat of attacks through computer networks becomes a large issue. Host Based Intrusion Detection is a part of security system that protects hosts from various kinds of attacks. It also provides a great degree of visibility (of system activities). It is quite widest that HIDS are vulnerable to attacks. An adversary, if successfully enters in a system can disable HIDS or modify HIDS rules to hide its existence. One can easily evade HIDS. In [7] we propose a new architecture that protects HIDS from such attacks. In this paper, we have proposed a new mechanism to check integrity of log files. We have discussed its affects on performance of system.
