Moving target defenses with and without cover deception

Background According to http://cybersecurity.nitrd.gov/page/moving-target, [1] “Research into Moving Target (MT) technologies will enable us to create, analyze, evaluate, and deploy mechanisms and strategies that are diverse and that continually shift and change over time to increase complexity and cost for attackers, limit the exposure of vulnerabilities and opportunities for attack, and increase system resiliency. The characteristics of a MT system are dynamically altered in ways that are manageable by the defender yet make the attack space appear unpredictable to the attacker.”
