The US Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) announced today that it intends to run DoH (DNS-over-HTTPS) and DoT (DNS-over-TLS) DNS resolution servers for official government use, however, it advises agencies to disable DoH and DoT support on employees’ browsers until official CISA servers are available.
The agency issued a memorandum today to remind government agencies of their legal requirement to use the EINSTEIN 3 Accelerated (E3A) DNS server as the primary DNS resolver for any government workstations and communications.
