General design and security risk review for a new XSEDE InCommon Identity Provider

Review Summary

The following questions were raised during review:

Does XSEDE Duo exclude the use of SMS-based passcodes according to ?

In XCI-30 we're simply using whatever XSEDE Duo authentication methods are enabled by XSEDE. Brian will raise this Duo policy question with Sec Ops.

Can anyone who registers with XSEDE use this service, or are there additional restrictions? Does it require an active or past allocation? Does it require vetting by XSEDE staff?

Anyone with an XSEDE portal account can use it, similar to There are no additional restrictions.

Are we going to add the "affiliation" attribute, and is so, how will it be populated?

No, we won't provide an affiliation attribute. Affiliation is optional according to, and since XSEDE is not authoritative for a person's institutional affiliation, it would not be correct for us to assert it.

Version 1.1 of includes clarifications to address the above questions.
