Summary: Two key features of the Homeland Security Department’s cybersecurity program known as Einstein are going the way of the VCR, the IPod and the teletype. The Cybersecurity and Infrastructure Security Agency is putting two Einstein 3A services out to pasture in the coming weeks. Specifically, CISA told agencies earlier this fall that it will be turning off two capabilities as of Dec. 22: Email filtering capabilities and domain name service (DNS) sinkholing services. DNS sinkholing protects against the use of domain name server as a means to establish communication with compromised hosts or to distribute malware. This capability is achieved by redirecting user traffic that matches known cyber threat indicators to a safe host to prevent connection to a malicious host and collect data on the attempted malicious connection.
