OpenID and the web

by Steven Rakick :: Rate this Message:

Reply to Author | View Threaded | Show Only this Message

Hello list,

I'm curious what the group thinks about the recent
surge in support for OpenID across the web and the
impact it will have.

1) Beemba - http://www.beemba.com
2) ClaimID - http://www.claimid.com
3) MyOpenID - http://www.myopenid.com

These sites are gaining in popularity quickly and with
the announcements of support from big players Yahoo,
Microsoft and Google, combined with smaller web2.0
celeb-run sites like Digg, OpenID appears to what will
eventually be the norm.

Thoughts?

I've also noticed that many of these sites are
bundling Information Card support (CardSpace on
Windows). Sounds like a good idea as it compliments
OpenID and helps address some weaknesses.

Again, any thoughts?

I'm really just interested in a dialog.

Are you sure?  Passport and Liberty Alliance also had lots of press and
support, but they never seemed to get off the ground in any big way any
more than CORBA, X.500 directories/LDAP, PKI....

The ideas may be good, but cooperation among competitors has always been
low and slow.

Sounds fine, but who's really going to adopt the key so it's more
meaningful than for paypal/ebay users, few of whom really care whether
there's a key or not to sell their collectible cards or other used trinkets.

I see that this would be useful to me as a web site that would like to
have such authentication for "free," but why would Verisign/Payapl want
to do such authentication for others for free?  Can they sell
advertising for an authentication check, or will they attempt to charge
using companies in the future for such checks?  It may even lead to
litigation, despite contract terms, that suggest if they "vouch" for the
authentication that they'll somehow be blamed for the scam.

And it seems that scammers will just use phishing sites to collect this
info, and then use the same two factors to try to scam the real web site
-- as long as they do it within 30 seconds, a time that's reasonable for
any electronic scam (there's no need to pause).

I've not  heard of anybody actually using the $5 paypal key.  It's not
to say nobody does, just the original question was about any uptake
we've seen, and I simply replied that we've not see any, nor have any of
our customers/users requested it (yet).

Personally, I don't see the use. Its just as much trouble to configure  
it for the supporting sites, as it is sign up for that site in the  
first place. Most of the people that support it now, I already have  
'regular' accounts for, and no compelling reason to switch it -  
especially if I'm in a hurry (which like most of us, is all the time).

And while support surges - I don't see adoption picking up the same  
way. Only my geek friends know about it, and even less of those people  
even use it.

Unlike passport and other big splashes in this space, at least its  
more of an open system. Passport (which was first code named  
hailstorm) never really made it past Microsoft's gates, and eventually  
just morphed into MS's Live ID today... in other words, their single-
sign-on solution for their own network of web stops). But like another  
poster indicated it was a lot of press with out a long lasting impact.

Maybe Open ID is different, but I haven't been impressed yet.

Yes, it is difficult to configure it for supporting sites.

But it does save us from registering at multiple webistes &
remembering the passwords of each of them.

It also makes it that much simpler for a malicious user to gain access
to every account you have after getting the password for only one.

If you use a different account name and password at every single
website, then if one account is compromised then all your other
accounts are safe.

But it also makes it easier to use stronger authentication. Nobody
would want to put up with, say, tokens or client certificates for
*every* website they use. For your online banking, maybe, but not for
your email and your blog and 20 random forum websites. But if you only
have to sign in once, your tolerance for security measures should go
up.

My main question, without having looked into it yet, is what kind of
protocols this uses. There is already SAML, for instance. Has OpenID
invented yet another way to do SSO, or are they using an existing
method?

Single sign-on only is truly useful if nearly all sites adopt it,
unfortunately.  After all, I have a Password Safe file that contains 225
entries now (many are business-related, but many are for the various
personal sites I'm registered at).  If 25 sites adopt a common SSO, I'd
still have 200 entries, meaning I'd still need/use Password Safe (or
other password manager, which is really extremely useful and easy to use
and allows me to effectively remember all passwords by only remembering
one good pass phrase that never is shared with anybody).

If they all adopted, then I wouldn't need it, which would be awesome,
but seems unlikely to happen, and of course there are passwords I have
to "remember" that are not for web sites.

Also, isn't entering the pseudo-random numbers subject to MITM with
replay attack?  I've not researched it much, but in general you need to
ID yourself and give the value, at which time the info used could be
replayed.

Also, those in control the ID databases have to be trusted that their
employees/contractors/outsourcers won't somehow steal or otherwise lose
control of the data, something we see all the time with sensitive
financial and medical records.  If you break my password at one site
today (such as a data loss or other phishing scam, etc.), you don't get
access to all my accounts like you would through SSO.

Don't get me wrong, I like SSO in general, but I think "universal SSO"
is extremely unlikely.  There are control issues, liability issues, risk
management issues and just plain old competitor cooperation issues.

Unfortunately another drawback is that SSO (in general) makes XSRF even
more dangerous as logging in one malicious site or if you have a Trojan
might compromise your data in several others sites and open the door to
a chain reaction similar to the XSS worm for Myspaces.

However SSO is a need for many people that anyway use password recycling
to obtain the "same effect".

If well used SSO could be beneficial as you can learn one single strong
password than dozens of easy-to-remember.

Notice the "if well used" at the beginning of the statement "there is no
patch for stupidity"

This is really not so, since most users sign up with the same email
address. All an attacker needs to do is crack the email account and use
the "forgot password" feature on most websites. Like it or not, most of
us already have a single PoF in the security of our online identities.

That is an attack that is relatively easy to prevent. If a malicious
user has the password, then no measure of protection can stop them.

Almost nobody does that in practice, though, because most people still
manage their account names and passwords in their heads, and can't
remember too many different account names and passwords.  The case of
a person who meticulously uses unique account names and passwords is
sufficiently rare that engineering to that case would present either
substantially decreased usability or substantially increased risk (the
risk would rise as users worked around the unique account
name/password "problem").  Engineering should take account of the
actual user population.

Now, given the typical population, a single-sign on such as OpenID
might present an opportunity to a malicious user, but it also provides
the owner of the OpenID with one-stop-shopping for revoking the
password and limiting the damage.  Again, given the typical user, who,
statistically, will make poor password choices, the recovery benefit
may outweigh the compromise risk.

Additionally, there would be nothing to prevent a user from having
multiple OpenIDs.  OpenID providers should have different levels of
service with different authentication strengths -- from
username/password to tokens, or whatever.  Then the user can use their
choice of OpenID with a particular account, making the choice based on
the strength of authentication vs. the risk of the account. (I'm not
sure if I really care whether someone gets my Slashdot comment
account, but I would care about them having my Amazon One-Click
account [if I weren't too paranoid to One-Click].)

The other issue here is that session-level authentication still leaves
exposure to MITM attacks, if the session credential is replayable.
Web apps should be requiring secondary authentication for sensitive
transactions, even when the user has already authenticated.  (Amazon
and Yahoo! do this.)  There ought to be some mechanism for the site
and OpenID to recognize that a new authentication is required for a
particular transaction.  Does anyone know if OpenID does this?  I've
got some reading to do.

       Pete.

I think that OpenID is concerned more with the problem of "Federating"
identity - which is corollary to SSO - but not necessarily the same Thing.

Microsoft tried web SSO with Passport.  It was viewed as proprietary, and
requiring full trust in Microsoft.  The new Microsoft effort is around
CardSpace, a WSsecurity - oriented framework and client API, extensible to
consume SAML, etc.  This is a federation play, that can aggregate signon and
authorizations.

That the OpenID tent seems big enough to accommodate CardSpace is indication
that federation of ID is more than just SSO.

I completly agree here openID as a protocol can support varying levels
of security including security tokens & pki.  currently most
implmentations are for services where as said above people dont really
care.  we accept that these services are not as secure as our bank.

personly i think openID is perfect for the use it provides.  with a
password system it isn't that secure, its online and gives access to
many accounts; however they are all accounts you dont care about.  if
it where a SSO for my banks i would expect to be using a certificate
but this wouldn't exclude openID.

Well thats my two pence...  As where on the subject i was curious what
people thought about shibboleth.  about 15 countries have adopted it
for either education or health* as an SSO to many online journals.
what do people feel are the security pros/cons here
