Einstein 3 “will draw on commercial technology and specialized government technology to conduct real-time full packet inspection and threat-based decision-making on network traffic entering or leaving these executive branch networks,” according to a DHS assessment from March 2010.
“The goal of Einstein 3 is to identify and characterize malicious network traffic to enhance cybersecurity analysis, situational awareness and security response. It will have the ability to automatically detect and respond appropriately to cyber threats before harm is done, providing an intrusion prevention system supporting dynamic defense.”
Einstein, developed by the U.S. Computer Emergency Readiness Team, was originally released in 2004 and was voluntary until 2008. DHS was in the final stages of deploying Einstein 2 in January, according to a Jan. 28 Federal News Radio story.
