Free and open-source software (FOSS) is not merely common on the Internet; it is a deeply embedded and essential foundation of the Domain Name System (DNS), the backbone of how we connect online.
The ICANN Security and Stability Advisory Committee (SSAC) is pleased to announce the publication of SAC132: The Domain Name System Runs on Free and Open Source Software (FOSS).
Why This Matters Now
As governments around the world explore new cybersecurity regulations, the ubiquity of FOSS in DNS operations—from domain registration to retrieval—means that policy decisions made today will have direct implications for the Internet's security and resilience tomorrow. SAC132 provides timely, nontechnical guidance to ensure that new policy and regulation serve to strengthen, rather than inadvertently weaken, this critical infrastructure.
