Assurance

["Roy, Nicholas S" <>]

A question I have is what kind of authentication services are schools running 
who feel that they can use passwords to achieve Silver?  Specifically, what 
is your central source of authentication?  What will end up providing the 
verifier role to your Silver-compliant IdP?  What kind of clients of this 
service do you have (ERPs, *.webapp, workstations (Windows, OS X, Linux, 
other?), printers, file servers, network appliances, etc.)  How tightly 
controlled is access to the service?  What kinds of authentication endpoints 
are available (LDAP, LDAPS, Kerberos, RADIUS, web services, etc.) how are 
those endpoints protected and from what network scope can clients connect to 
them (only on-campus, off campus, only via a VPN, other?)  Do you provision 
passwords to other authentication services that aren't your central provider? 
 How do you plan to assess and/or enforce client behavior (for example, use 
of SSL for web forms that validate passwords against your authentication 
service), or do you consider that out of scope?

I'm not saying you can't use passwords to achieve Silver, but the project 
complexity seems pretty high in a big, heterogeneous campus environment.

Subject: [Assurance] silver and two-factor ...

I'm wondering why so many sites that are interested in Silver are so 
interested in two-factor....

I haven't looked at the Silver profile in a long time. But, my memory is 
that strong passwords, stored sufficiently securely, and not replicated 
into uncontrolled environments (eg google), would pass muster with 
Silver. I'm assuming, of course, that the other Silver criteria (eg 
around identity proofing, account claiming, etc) would also be met.

I can imagine that there may be issues with those passwords passing 
through a variety of systems (eg systems that are then authenticating 
users against a central ldap, for instance). But, that's just a guess -- 
I would be interested in hearing about specific concerns that are 
driving sites toward two-factor.

Thanks for any light you can shine on this!
