Discussion

New member Introductions

Baseline Expectations (BE) 2020 consensus doc

Key documents:

Reminder that there are 5 possible components of BE that CTAB is working to implement in upcoming phases.

Numbers 4 and 5 below will likely be postponed for a future year, beyond 2020.

  1. SIRTFI Framework
  2. Encryption for endpoints for IDPs and SP 
  3. Inclusion of Error URL in IDP metadata (no requirement for content; point to working group)

    FOR FUTURE
  4. Support for REFEDs MFA profiles  (for future)
    1. Need to detail  how organizations would comply with this, thanks to Eric G for his work on this
  5. IDP supports attribute bundling (R&S now; future anonymous attribute bundle) (for future)


  • It was noted that the clarification doc only included items 1, 2 and 3 .
  • There is a draft of clarification for items 4 and 5, but that had been removed from the draft.
  • Decision:  return the material on 4 and 5 to the draft, but explain that they are for the future most likely, and explain what likely still needs to be figured out (DONE)
  • Also will include clarification  of 4 and 5 (items for beyond 2020) on the eventual FAQ wiki page. 


  • CTAB reviewed recent updates to the  BE doc
  • It was noted that we do NOT want to be in the position of needing  to revise the BE doc every few months 
  • Dispute resolution will be used to resolve situations on non compliance, such as for BE statements like this:
    • 1.3.3. All IdP service endpoints must be secured with current and supported transport layer encryption
  • We may want to be more specific around “current and supported”
    • Suggestion to add the word “strong”
    • Need to work on the wording for 1.3.3 more later 
    • There will be some automated tests around endpoints, for the TLS security requirements.
    • For the SSL Labs tests, there were a few “F”s, in the preliminary analysis performed by Shannon Roddy  
    • Some think we need to be more specific.
    • SURFnet uses the SSL Lab grading
    • If InCommon will use SSL Lab grading, we should be more explicit

  

  • For the SP side, we do not mention Error URL
    • Could specify that SPs must be ready to use an Error URL
    • Whether the SP can handle Error URL impacts the user experience
  • Suggestion to focus on security as the theme for this phase of BE
    • And tackle user experience issues in next phase of BE
  • There is a proposal for a task force that may address the user experience
  • Decision: No change to the doc at this time around mentioning SP side Error URL
  • Perhaps errorURL by SPs should be considered in a future rev of BE. 


  • Do we want to add any sub-bullets in section 3 for Federation Operators?
  • AI Albert consult with Nick Roy and AnnW on suggestion to state  in section 3.1.1 that federation operator will monitor and report back to CTAB on compliance 


Timeline for BE announcement and moving into consensus period

  • Consensus period 
    • Start when
    • how long?
  • When do we announce consensus achieved ?
  • How do we field feedback during consensus?
  • CTAB had hoped to have community consensus period kickoff info for the community by end of January 2020
  • A future CTAB meeting should  discuss logistics of running the community consensus process.
  • AI TomB outline the steps we need to talk to kick off community consensus for next CTAB call
