A little bit of everything without actually being much of anything

Being Hacked is ok (if you’re paying for it)

There were many great speakers at TEC 2009 this year (and I was there too!), especially in the Federated Identity track.  One of the things that I was interesting, was during one of the sessions the speaker described many of the current non-federated authentication schemes that SaaS providers can use.  The implementations may have varied slightly, but they often amounted to “Give us your user name and password, and we’ll authenticate you across some out-of-band channel.”  The deployment of this service requires that extra channel for auth, sometimes being a VPN connection, or an LDAP service that the provider can authenticate against…things like that.

A comment was made, something about the security risk that this poses; after all, it IS by definition a “man in the middle attack.”  The next couple of minutes were spent blasting this type of ridiculous design (after all, this was the federation track) and how horrible this was and people would never let this type of set up occur at their company.

Of course, that’s probably not true at all, is it?  After all, every application outsourcing project I’ve worked on includes the “user SSO” line item, but nobody says what that has to be.  And the corporate security risk analysis has to outweigh the hard dollar cost savings that were driving the project to begin with, which is why I suspect that the typical CorpSec risk analysis always ends up somewhere in the Billions of dollars with a picture of the company going down in flames.  Yet even that’s not enough even enough to stop the project from moving forward, because at the end of the day, IT departments are often not empowered to say “No, you can’t do that”…rather…we end up saying, “This sucks, but here’s the best that we can do to make it work.”

And that is why, a man in the middle attack, even one with credential harvesting, is OK if the company is paying someone to do it (and saving real money in the process)

And it’s why now more than ever we need comprehensive federated authentication solutions, so we don’t have to get run over by these hacks.
