Dear Colleagues, I hope you're having a great summer! As the temperatures cool a little in Europe our thoughts turn to autumn and RIPE 93 in Sofia. Our Security Working Group session is currently scheduled for Tuesday, 27 October 2026 at 16:00 (UTC +2) Since RIPE 91 we are now using Pretalx for this purpose. Please submit your proposals ideally by 18 September 2026 via: https://pretalx.ripe.net/ripe-93/cfp When submitting, please keep in mind: - Talk type: This field is not relevant for our WG – you may simply choose “Talk”. - Track: Please select "Security WG". - Duration: Indicate the total time you will need, including Q&A. More information on how to submit a talk can be found here: https://ripe93.ripe.net/present/call-for-presentations/ If you have questions about potential topics or the session in general, or think you may not make that deadline, please contact us at security-wg-chairs@ripe.net As usual, both in-person and remote participation in the working group will be possible. We look forward to your submissions.
