DHS/NPPD/PIA-008 EINSTEIN 2

The original Privacy Impact Assessment (PIA) for EINSTEIN 1, dated September 2004, explained that EINSTEIN 1 analyzes network flow information from participating federal executive government agencies and provides a high-level perspective from which to observe potential malicious activity in computer network traffic of participating agencies' computer networks. The updated version, EINSTEIN 2, will incorporate network intrusion detection technology capable of alerting the United States Computer Emergency Readiness Team (US-CERT) to the presence of malicious or potentially harmful computer network activity in federal executive agencies' network traffic. EINSTEIN 2 principally relies on commercially available intrusion detection capabilities to increase the situational awareness of the US-CERT.

Note:  This system received a PIA 3-year review on June 28, 2013.
