[ISN] GAO: Early look at fed’s ‘Einstein 3’ security weapon finds challenges

One of the most effective tools the government has is the National Cybersecurity Protection System (NCPS), known as “EINSTEIN.” In a nutshell EINSTEIN is a suite of technologies intended to detect and prevent malicious network traffic from entering and exiting federal civilian government networks. The Government Accountability Office has been tracking EINSTEIN’s implementation since about 2010 and will later this year issue an update on the status of the system. But this week, it included some details of its report in an update on the state of federal security systems, and all is not well. Preliminary EINSTEIN observations from the GAO: •The Department of Homeland Security [which administers EINSTEIN] appears to have developed and deployed aspects of the intrusion detection and intrusion prevention capabilities, but potential weaknesses may limit their ability to detect and prevent computer intrusions. For example, NCPS detects signature anomalies using only one of three detection methodologies identified by NIST: signature-based, anomaly-based, and stateful protocol analysis. Further, the system has the ability to prevent intrusions, but is currently only able to proactively mitigate threats across a limited subset of network traffic (i.e., Domain Name System traffic and e-mail).
