During my tenure as Secretary of DHS we have worked aggressively to enhance the cyber security of federal civilian executive branch networks. This has included deployment of EINSTEIN across all civilian departments and agencies. EINSTEIN 1 has the ability to monitor traffic across these networks. EINSTEIN 2 has the ability to detect unwanted or suspicious traffic in these networks. EINSTEIN 1 and 2 have been deployed since August 2015.
E3A has the ability to prevent unwanted intrusions and exfiltrations by known bad actors. And, to date, E3A has blocked over one million potential cyber threats on the networks it is covering. E3A is also valuable in that it has the capability to identity unwanted intrusions or exfiltrations with the use of classified information. E3A will also serve as a platform for future technology that will block suspected bad actors.
