Security App Modeled After Immune System
Start-up Sana Security looked to the human immune system in developing its new application security platform.The security industry has always looked to the field of medicine for metaphors and ways of thinking about network protection. Now, Sana Security Inc., a San Mateo, Calif., start-up, is extending that relationship to another level with the introduction Monday of its Primary Response application security platform. The software works by observing application-operating system interactions and learning the code paths that each application uses during its normal operations. The system develops a profile of each applications behavior and then blocks anything that falls outside that profile. As a result, the system produces a remarkably low number of false positivesas few as two or three per month in some customer environments.
The concept was taken from the human immune systems ability to recognize potential infections and begin defending against them before they reach their intended targets. The software is the brainchild of Steven Hofmeyr, Sanas founder and chief scientist, who came up with the idea while doing research for his doctoral thesis.
