CISA published a guide on using Encrypted Domain Name System (DNS) for federal civilian agencies to improve cybersecurity and meet OMB Memorandum M-22-09 requirements.
Traditionally, the DNS protocol didn’t have ways to make sure requests and responses were confidential, secure, or authentic. However, the M-22-09 guideline requires agencies to encrypt DNS traffic and use CISA’s Protective DNS capability for egress DNS resolution. This guide will help agencies implement technical capabilities for their networks, DNS infrastructure, on-premises endpoints, cloud deployments, and mobile devices.

“As the operational lead for federal cybersecurity, CISA developed this guide to assist federal agencies with understanding and implementing key actions and protocols to begin encrypting DNS traffic,” said Eric Goldstein, Executive Assistant Director for Cybersecurity, CISA. “This guide will help agencies progress further in their zero trust security journey. CISA continues our efforts and collaboration with agencies to modernize federal agency cybersecurity successfully and securely.”
This document provides resources to help agency personnel understand the requirements and engage in the transition work. It includes a high-level implementation checklist, recommendations for phased implementation, and technical guidance. Implementing encrypted DNS will align civilian agencies’ security architecture with zero trust principles.
This guide is for federal agencies, but all organizations are encouraged to use it as a benchmark for applying zero trust efforts.
