First Tabletop Exercise (TTX) at SOSS Community Day North America

We’re excited to announce the agenda for the Tabletop Exercise (TTX) at Secure Open Source Software (SOSS) Community Day NA in now live which will take place on April 15, 2024 in Seattle, WA. 

What to Expect

The TTX is a 90-minute interactive session during SOSS Community Day North America, open to all SOSS Community Day attendees as audience observers. The TTX will have two phases. The first phase will be the execution of a security incident scenario, with selected panelists going through the scenario and playing their respective peronas as an open source maintainer, a software and package registry operator, and open source software consumer. The second phase will be a postmortem discussion, where panelists and selected contributors will be asked to provide insights and suggestions on how things went, and how the process could be improved. 

The panelists and contributors bring their expertise in open software security ranging from open source production, distribution, consumption, vulnerability management to incident response. 

The exercise will be followed by a Q&A session where the audience will have the chance to pose questions to all participants (panelists and contributors).
