Abstract
Current approach to security is based on perimeter defense and relies on reactive systems like firewalls, intrusion detection and prevention systems. These systems require a priori information about attacks and vulnerabilities. McAfee reports identifying 100,000 new unique malware each day. Thus trying to prevent intrusions is becoming impractical. Although it is difficult to model and predict a hacker’s moves, a defender might be able to make hacker’s task harder by adopting Moving Target Defense (MTD) proactive security strategies. In this paper, we present SCIT, our MTD approach. We use Attack Surface assessment to evaluate SCIT. A system’s attack surface is the subset of its resources that an attacker can use to attack the system. Manadhata uses attack surface reduction / shifting as means of assessing MTD. In this paper, we compare the dynamically changing Attack Surface for three system architectures (1) Static Systems; (2) Basic-SCIT and (3) Diverse-SCIT.
