In a statement concerning the deployment of cyber-threat detection and defense system EINSTEIN 3 Accelerated (E3A), DHS Secretary Jeh Johnson reports the digital invader mitigation service contributes coverage to all civilian cabinet-level departments, as well as 45 federal departments and agencies, including the Departments of Energy, Commerce, Homeland Security, Interior, Justice, Labor, State, Veterans Affairs and the Office of Personnel Management. This is up from 28 percent of the civilian workforce in May 2015 and 88 percent in November 2016. Congress called for a ramp-up of EINSTEIN deployment in 2015 after news broke of the massive hack of OPM networks. Johnson reports that E3A has blocked over 1 million potential cyber threats on the networks covered, identifying malicious traffic and halting exfiltrations by bad actors. “DHS is working with the remaining departments and agencies to employ E3A protections on their networks within a short period of time,” said Johnson. “I encourage these few remaining departments and agencies to work with us to deploy E3A and other cybersecurity protections across their networks as soon as possible.” More information on E3A can be found on the DHS website.
