moving target defense; cyber agility

Moving Target defense (MTD) is a new Cybersecurity paradigm for deterring and disturbing attacks proactively in order to counter the ?asymmetry? phenomena in cyber warfare. A number of moving target techniques have been recently proposed to inverse this asymmetry by randomizing systems? attributes (e.g., configuration) and exhibiting non-determinism to attackers. However, due to potential inter-dependency between various MTD mechanisms, an ad hoc combination of MTD techniques can cause profoundly detrimental effect on security, performance and the operational integrity of the system.
