Einstein 3 intrusion prevention system analyzes traffic to and from executive-branch agencies to block threats at the ISP level.
The Department of Homeland Security’s Einstein 3 intrusion prevention system, launched last summer, raised the bar for security technology capable of operating at carrier-grade network levels, rather than just within the enterprise.
Einstein is a managed security service delivered through Internet service providers that serve executive-branch civilian agencies. Through a public-private collaboration, DHS provides custom signatures to federal agencies’ ISPs to block malicious traffic, both incoming and outgoing.
Moving analysis of government Internet traffic to ISPs for security purposes was controversial when Einstein 1 was deployed in 2004, but it was merely an early step in what Tim Sullivan, CEO of security firm nPulse Technologies, said is the inevitable move of cybersecurity to a managed service.
