Moving Target Defense
Dynamic network defense (or moving target defense) is based on a simple premise: a moving target is harder to attack than a stationary target. In recent years the government has invested substantially into moving target and adaptive cyber defense. This rapidly growing field has seen recent developments of many new technologies—defenses that range from shuffling of client-to-server assignments to protect against distributed denial-of-service (DDoS) attacks, to packet header rewriting, to rebooting servers. As researchers develop new technologies, they need a centralized reference platform where new technologies can be vetted to see where they complement each other and where they do not, as well as a standard against which future technologies can be evaluated. In this podcast, Andrew Mellinger, a senior software developer in the SEI's Emerging Technology Center discusses work to develop a platform to organize dynamic defenses.
