In the arms race between cyber attackers and cyber defense technologies, attackers currently claim control. They employ sophisticated deception techniques designed to evade traditional and even “next generation” defense mechanisms, for example by hiding malicious behavior and disguising it as benign or unknown behavior. We outlined these techniques, collectively known as Moving Target Attacks (MTA), in our previous blog post. But there is a cyber defense strategy that breaks the attack-patch cycle. Moving Target Defense (MTD) uses counter-deception techniques that constantly change the target surface, so that attackers can’t get a foothold.
