Cybersecurity System Mimics Human Immune Response

The U.S. Department of Homeland Security's Bruce McConnell recently released a white paper that describes a healthy ecosystem of computers that work together to fight cyberthreats. McConnell says the first step to developing the ecosystem is creating a computer system that can automatically recognize and react to threats.

However, a major obstacle to such a system is developing computers that can authenticate interactions, says Science Applications International Corp.'s Ross Hartman. He says researchers currently are studying new models of nature-inspired defenses as a way to protect computers from new threats. Hartman says that McConnell's paper, "Enabling Distributed Security in Cyberspace: Building a Healthy and Resilient Cyber Ecosystem with Automated Collective Action," is a positive response to rising threats and will lead to new innovations from cybersecurity experts.
