SHARING GUIDELINE: PUBLIC (TLP:WHITE) Greetings, The REN-ISAC has issued the attached advisory to call attention to the upcoming implementation of DNS over HTTPS (DoH) in Firefox and Chrome browsers. The changes to how the browsers conduct domain name resolution will impact your users and IT security and operations. We recommend institutions understand how: + domain name resolution is conducted at their institution + DNS choices can impact user privacy and security + IT security operations and protections may be impacted + user support may be impacted + reliability, availability, and performance may be impacted and, to + determine whether you want to allow, discourage, or disallow use of alternative DoH recursive resolvers at your institution + communicate with your users. Many thanks go to the REN-ISAC Technical Advisory Group [1] for assistance in developing this advisory. Questions or comments can be referred to soc () ren-isac net. On behalf of the REN-ISAC team, Doug Pearson Technical Director, REN-ISAC [1] https://www.ren-isac.net/about/governance/tag.html -o0o- ********** Replies to EDUCAUSE Community Group emails are sent to the entire community list.
