University to Create New Cybersecurity Approach Inspired by the Human Body

Researchers at the University of Arizona are developing a fresh approach to cybersecurity modeled on the human central nervous system. 

The new method, which is being created as part of the Partnership for Proactive Cybersecurity Training project, will aim to detect and neutralize cyber-threats in their earliest stages before they have a chance to do any serious damage. 

Inspiration for the project came from human biological responses; for example, how the body's immune system fights a virus and how a person will instinctively pull their fingers away from a burning hot surface before their brain has even received the message that the body is at risk of harm.

"I felt we could learn about how the body protects us by reacting to threats and maybe apply it to cyber by building a 'cyber immune system,'" said Salim Hariri, UA electrical and computer engineering professor and the project's principal investigator. 

"We're trying to build these abilities where, when somebody attacks your computer, these measures can detect the attack and act on it before you're even aware something is compromised."

In contrast with security methods that deal with cyber-threats in a reactive way, the new system being constructed is being designed to function proactively. The plan is to use artificial intelligence and machine learning to train machines to recognize cyber-threats on their own, as a doctor might recognize diseases from their symptoms. 

To stop the threats before they infect a network or device, researchers will also teach the machines how to recognize threats as they evolve and how to execute a wide range of cure ..
