Many HIDSs exist and security practitioners need a way to determine the optimal security solution for their environment. Current evaluations of HIDSs focus on detection accuracy and typically do not account for the possibility that an adversary may subvert the HIDS and modify the outcome. As some elements from the HIDS need to reside within the system under supervi- sion, evaluating the strength against HIDS subversion is critical. This paper defines HIDS subversion and presents HIDS resiliency as a metric of HIDS strength in the event of an attack against the system being supervised. To estimate HIDS resiliency, we evaluated the inde- pendency between the system being supervised and the HIDS. Then we integrated resiliency into current frame- works to evaluate detection accuracy. %B Journal of Information Assurance and Security %V 4 %P 001 - 009 %8 2009/// %G eng %U http://www.softcomputing.net/jias/molina.pdf %N 1
