sig-auth bi-weekly meeting

This video presents a technical discussion about implementing conditional authorization in Kubernetes. The team explores two approaches for handling conditional authorization responses, focusing on how to maintain security while allowing flexible permission policies 0:37-1:10. They examine the trade-offs between caching partially evaluated conditions versus requiring full re-evaluation 5:24-8:03. The discussion includes complex scenarios like impersonation filters and aggregated APIs 19:03-22:50. There's significant debate about information leakage concerns when conditions are visible to users through self-subject access reviews 38:00-42:03. The team considers whether to deprecate the existing rules review API in favor of new approaches 34:39-36:16.
Key Takeaways:
• Two approaches for conditional authorization are being compared: caching partially evaluated conditions versus full re-evaluation 5:24-8:03
• Complex scenarios with impersonation filters and aggregated APIs present technical challenges for implementation 19:03-22:50
• Information leakage concerns exist when conditions are visible to users through self-subject access reviews 38:00-42:03
• The team considers deprecating the existing rules review API in favor of new approaches 34:39-36:16
The discussion highlights the technical complexity of implementing conditional authorization while balancing security, performance, and usability requirements.

All right. This is the February 4th uh gap review for conditional authorization. Go for it, Lucas. >> Yep. So, yeah, if we start off by uh or kind of where we where we left uh last week. Let me see if I find this one. I think yeah now I should you should see my screen I think on the presentation. So yeah just uh just to summarize nothing nothing uh kind of you know new here but yeah just we want to give we want to make a subject actor view kind of give us fast responses initially and then especially we want to keep kind of um [clears throat] the response like everything that can give us an unconditional response. We want to kind of see that and and kind of just go through the normal flow for all of those things which is probably going to be 95 plus% um at at least. Um then always keep symm…
