Facebook is going to allow user names on June 12th

Posted by BPuhl on June 10, 2009

If you use Facebook, you might notice a box when you log in that says beginning June 12th, Facebook will allow registration of user names.  If you “click here” to have them send more info, you’ll receive this in your registered email inbox:

Starting on Friday, June 12th, at 9:01pm, you’ll be able to choose a username for your Facebook account to easily direct friends, family, and coworkers to your profile.

To select your username, visit the link below after 9:01pm on June 12th:

http://www.facebook.com/username/

To learn more about usernames, visit the Help Center:

http://www.facebook.com/help.php?page=896

Thanks,

The Facebook Team

 

So what does this mean?  Well, for one thing, it means that if you’ve got a common name – or – if your like me, and you KNOW that there’s someone else on Facebook with the same name (since he and I are actually friends on Facebook), then it means that you want to “claim” your user name as soon as the application opens.

I did seen an interesting article here http://www.huffingtonpost.com/jonathan-handel/trademark-protection-and_b_213756.html about trademark registrations and how Facebook intends to handle squatters.  So don’t bother trying to register facebook.com/McDonalds, you won’t have it for long if you do. 

I like the very last part of that article though.  There is already a recommendation for what to do, if somebody maliciously claims not only your trademark, but also fills out the forms sufficiently such that you (the legitimate owner of the trademark) actually can’t use the automation to claim it back.

Oh how much fun Identity Management can be :)

AD in the Perimeter Network

Posted by BPuhl on April 27, 2009

A new whitepaper has been published providing the guidance you need to deploy Active Directory, and specifically RODC’s, in a “Perimeter Network” (the network segment formerly known as DMZ).

I know that a lot of folks have come to me, asking for help/guidance on putting RODC’s into the DMZ rather than putting full DC’s or having a separate forest.  This should provide the information you need to keep safe, secure, and most of all…functional.

Some of the topics include:
•         Security considerations and configurations for RODCs in the DMZ 
•         Network configurations for RODCs
•         Application compatibility with RODCs in the DMZ
•         Step by step instructions and a sample script to help perform domain join using RODCs

http://technet.microsoft.com/en-us/library/dd728034.aspx

 

Brandon pointed out to me, that the doc is nice, but having a downloadable version would be much nicer.  We fired off a quick mail, and there will be a downloadable version of the document in the download center in the near future.

Collection agencies….

Posted by BPuhl on April 10, 2009

I have had a few discussions recently at work about ways to make things more convenient.  Either convenient for our users (cloud services), convenient for our customers (single sign on), etc… 

But a one-two punch hit me, when I just had 2 close friends – both of whom have been impacted by the financial mess – have their identity attacked because something that had built in security controls (checks) was made to be more convenient (by phone), and in the process all of the controls were removed so my friends were vulnerable.

Really, I call it fraud, or identity theft, or just plain robbery…  But in both cases, the banks say that there are no laws against this:

My friend lost her job, and fell behind on payments.  She owed $1100 for this months rent, $4400 to a creditor that by this point had gone to a collection agency, and some other bills (credit cards, gas, electricity, etc…).  Through creative budgeting and working with parents, friends, and anyone else, she scraped together $5000 that she could use. 

With the new money available, she came up with the following plan:

   $1100 for rent
      900 for the other bills
      500 to the collection agency
      The rest to be used for the following months rent, payments, etc…

She called the collection agency, and agreed to pay them $500 now, and then set up a payment plan for the rest of the money.  That’s where the first mistake happened:  They wanted the payment as a “check by phone”.  So she voided a check, gave them the info, etc…

The collection agency first attempted to clear the check for the full $4400.  Because the money was in the account, the check cleared – of course, this meant that she couldn’t pay any of the other bills, or her rent, etc…  And she had already tapped out her friends, parents, etc…

You can imagine that the calls to the collection agency were like:  “Sorry, sucks to be you – we’ve got our money now”

The bank was equally useless:  “You gave them a check by phone, the money was in the account, they cleared it…Sucks to be you”

This was just completely ridiculous, but it shows that in the absence of standards or protocols, there is no shortage of people that will offer things for the sake of “convenience” which blow the hell out of “security”.  If you have to write a check and sign it, then you fill in the amount, etc…  modification of that is check fraud.  But those security controls went out the window when banks allowed people to do “checks by phone”, and there is absolutely nothing to prevent unscrupulous people from raping your bank account if you give them the information.

The second case is similar, but with a slight twist

My friend has slowly but surely been paying off debts that were racked up over a period of time, and has been working through one of those debt consolidation management companies.  Since she wasn’t getting the resolution that she needed from the company, she took back the money that was in their escrow account and started working with the collection agency independently.

On the first phone call, she had an $7,000 debt and worked with the agency to negotiate down to where they would accept $4300.  Seems like a good deal, so again, check by phone for $4300.

A couple of days later, she received a notice from the collection agency, indicating that they “Had an agreement for an initial payment of $4300”.  In other words, the deal they made on the phone was a lie, instead of negotiating the total, they just wanted an initial payment and were going to keep going after her for the remaining balance.

Ahhh…but the check by phone hadn’t cleared yet.

So a quick call to the bank, a $28.00 stop payment charge, and there was a stop-payment for that check before it cleared.

Good right?

Not so much.  2 days later, $4300 was withdrawn from the account anyway, by check #1001 (not the check number she gave them).  A long, convoluted, multi-transfer call back with the bank this time, and they could see where the initial check number had attempted to clear, been rejected (the stop payment), and then the company had re-submitted another check by phone with the different check number and got the money.

After several days of arguing, it’s still unclear whether the bank is going to say “Sorry, sux to be you” or if they are actually going to help.  I’m not holding my breath.

So again, the safety features around checks – being numbered, signed, amounts written (twice) – are all placed into the trusting hands of the least trustworthy person (the merchant that wants your money), and there is remarkably little recourse.  I suppose you could go get a lawyer, etc…  But during that time the money is gone, life still needs to be lived, and a lawyer is going to take 30% of whatever you get back anyway (or some amount of payment)…

All for the sake of convenience (to whom?)

There are better ways, one of which I really like.  I’ve had a credit card with CitiBank since college.  And many years ago, they came up with this idea of virtual account numbers for your credit card.  You can go to their website (or they have a downloadable application), and if you want to make a purchase, you can get a one-time use credit card number (with expiration and CVC) for that one purchase.  I haven’t used it in a while, but IIRC you can even specify the amount of the purchase you’re going to make (which is really the protection).  This is great, because the security of a credit card is handing the piece of plastic with the signature on the back to the person behind the register.  With online purchases, you can’t do that, so instead lets take the things which you can control (amount of purchase, usefulness of the number after it’s been used properly) and control those instead.  Reasonable mitigations.

This is the type of control that we’re going to need if we want to protect our resources in a more “convenient” (read: Online) world.

TEC 2009 Wook Lee Memorial Challenge

Posted by BPuhl on April 9, 2009

At The Experts Conference in Las Vegas this year, Stuart threw out the challenge to the DS MVP’s to come up with their list of changes they would like to see in Active Directory, but put it to the tune of an Elvis song.  After a midnight (mildly inebriated) recording session, and some fancy editing by the Quest Software production staff, here’s the result!

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

Posted by BPuhl on March 27, 2009

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.

EASI ID (pt 1.5)

Posted by BPuhl on March 26, 2009

Question for you

You’re Jon Smith, and you signed up for the TAA.COM (Totally Awesome App) application when you worked at Contoso, it was free and let you store all of your client data.  You signed up with the user name, JSmith@contoso.com.  Good thing too, because when you quit working at Contoso years ago, you took your clients with you.  Over the years, you either have never updated your login ID, or maybe the application won’t let you.

Now TAA.COM decides to break into the SaaS market by offering their totally awesome app to business customers, and Contoso signs up.  Who gets to have the JSmith@contoso.com user name, you (by virtue of being first), or Jerry Smith, the current JSmith@contoso.com who was hired after you left?

Even though Contoso has federated, single sign-on authentication – does it matter?

I guess another way to put this, is does an individual own the usage rights to their email address forever, or does the company own their namespace and all resources (ie. names) within it?  Worse case, what happens if Jerry signs in and see’s Jon’s information?

EASI ID’s (part 1)

Posted by BPuhl on March 26, 2009

When you log into a website which you use for personal stuff, for example using your Google or Windows Live ID; or even better, logging into Facebook or Myspace.  What do you use for a user name?

Intuitively I’ve known this for a while, but I have recently been having a ton of discussions about EASI logins, or Email As Sign In.  This makes sense, when you register at a website, they ask you for your email address, and that’s what you’re “user name” becomes.  Simple, easy to remember.

There are of course, a couple of flavors to this.  In the case of Facebook for example, you must “verify” your email address.  When you sign up, they send you an email, you click on it (proving that you have access to the email address), and then you get in.  Of course, not all services require verification, and for those, you can enter any email address you like.  Just ask Robert Schuler if he thinks verification is necessary when creating an online identity!

I just got back from TEC 2009, an excellent conference that I have the privilege of speaking at, where I always get into great conversations with a ton of incredibly smart folks.  Since I’ve been in this “EASI/Online/Enterprise Identity Convergence” kick lately, and since I was surrounded by a bunch of identity management professionals, i asked whether anyone had experienced issues with using their work email address for EASI logins to personal websites.  In general, the answers were either, ‘no, because I’ve worked at the same company for years and consider my work email my “primary” address’ – or – ‘Yeah, and it was the biggest PITA and I hope to never have to do that again’

The one answer that surprised me though, was one person who actually said that she’d worked at a company before, where they had hired a new person.  And they had actually provisioned this person a new account 3 weeks before the he was scheduled to start, just so he’d have that new email address and could migrate all of his online service accounts to it.  I’m honestly not entirely certain how this was a good idea, but alas we are all IT folks, and have to do what we’re told.  Kind of crazy though.

More to come on EASI ID’s, and some of the quirks we’re seeing as more and more enterprise services are moved to the cloud.

Security Evolution

Posted by BPuhl on February 21, 2009

My buddy Dan who used to work in Microsoft IT Security, and is now working over in the Information Protection product group (mostly known for RMS) wrote a doc back in 2005 on the evolution of security in the enterprise.  He had been asked for the doc so many times that he posted it to a blog about a year ago, but whenever I start thinking hard about federation, application authorization, claims based identity, and all of the other “fun” topics which make my days interesting, I occasionally need to go back and remember that being in IT is as much about where we are “at”, as where we are “going”.

This is the main graphic from the document:

evolution-of-security-controls-graph-only

From what I can tell, we are somewhere around the little tick mark that separate “near term” from “mid term”.  Things like IPSec, NAP, Windows Firewall, etc… have all done a pretty good job of moving the security from the network boundary to the host.  With Windows Server 2008 R2, Microsoft has finally productized Direct Access – which I can now admit that I have been happily been using for 2-3 years now, and probably couldn’t live without.

But when I think of the challenges in the identity space around federation, the separation between personal and business data, and how we’re going to protect the enterprise when everything is in the cloud – I can’t help but to think that maybe the arc on that “data” line is (unfortunately) a little too steep.  As hard as we try internally, the adoption around data protection is still far below what we need it to be.

Progress takes time, and I like working with the IPC team as they have a great things planned for the future.  Like everyone else though, it’s hard for me to “wait for the next release” to get the features I need.

Business Data and Personal Data (pot-A-to, pot-AH-to?)

Posted by BPuhl on February 21, 2009

How do you tell the difference between “business data” and “personal data”?  Since we’ve been diving head first into this whole federated identity thing, it’s turning out to be pretty darn important.

The best that I can come up with at this point, is the following guideline:

If you’re supposed to have access to a piece of information after you quit or are fired, then it’s personal

Man, I wish life were only that simple.  Here are a couple of examples of decisions from real life ADFS federations that we’ve set up between Microsoft and some of our business partners.

Microsoft employees in the US (and elsewhere) are provided medical and other types of insurance as part of their benefits package.  The HR team wants to leverage a vendor to manage most of the benefits, and provide SSO for employee’s.

Is this business or personal data?

By my definition above, this is pretty obviously business data.  Ah, however midway through the project, there was another requirement thrown out.  (I’m obviously stereotyping here, but for fun…)  It seems that a large number of Microsoft employees are married men, and some large percentage don’t want to manage anything remotely having to do with their family or finances, most likely because their wives won’t allow them to.  So during this project, we now need to allow an employee to provide access to the benefits portal for their spouse.

The solution?  Employee uses ADFS to sign into the portal, and then they can specify WLID’s that are allowed to log in and manage them as well.

Not bad, but the implementation went sideways.  What we’ve got now, is a case where users who are logging in from corpnet have to use ADFS, however ALL USERS that log in from the internet use WLID’s.

Operationally, this is really bad, because the only way you can tell from the internet, where a user is coming from, is by IP address – so if we add a new proxy server IP, we will have transient auth failures. 

From an IDM standpoint, the goal was that when a user was terminated, they lost access to the site.  They only have access because of their relationship with Microsoft (ie. it’s business data), and they lose access to it when they are terminated.  However instead of enforcing this with auth, we now have to rely on the HR, out-of-band, feed to notify the vendor of an employee termination.

Another example, occurred this past January:

In December, Microsoft and our payroll vendor federated an application such that MS employees in the US could gain access to their W-2’s (US tax documents) online, by signing into the application using ADFS.

It’s easy to interpret a W-2 as being business data, after all, it’s essentially a summary of your annual payroll, but it was this case that helped by boil me definition down to what I wrote above.

You see, in December we sent out this e-mail, we had a significant number of employees sign up for online W-2’s, which as part of the process they agreed not to need paper W-2’s to be mailed to them.  They would just print them out.

However in January of this year, Microsoft was one of several companies that unfortunately had to cut costs and lay people off.  Part of this process, was that the impacted users had their accounts disabled.

So to summarize the insult to injury:

-  A user signs up for online W-2’s
-  They are layed off
- And the account they need to use to access their W-2’s is disabled

This is a pretty clear case where we should have used some form of public auth provider like Windows Live ID or similar – essentially allowing users to get their W-2’s using their personal ID instead of tying the access to their business ID.

However you have to stop and ask yourself:  “If an employee accessing their W-2 is really a person accessing personal information, then what is an HR analyst that’s providing support, who has to access MY w-2 to give me the help I need?  Surely we could all agree, that this is a case of a business identity accessing business information!”

Even with RODC’s, AD Is Still A Distributed System

Posted by BPuhl on February 21, 2009

Yes, it’s true, Active Directory is still a distributed system.  (this is the part where you say, “Well, yeah, duh!”)  But with Server 2008 and Read Only Domain Controllers, the distributed system changes some.  Sure, there’s that “unplanned feature” in ROGC’s that I blogged about last time, but this time it’s different. 

Remember back in the day, we had to train application developers that although all DC’s were essentially equal, they were only ‘loosely consistent’, so it wasn’t reasonable to think that you could make a write on one DC, and then immediately query another DC and expect the data to be there.  Made sense, but recently in MSIT we found that even our own developers were sort of taking some of this ‘loose consistency’ for granted.

A couple months ago, we had an escalation from one of our regional sites, that all BitLocker installations to laptops in the site (which of course, has an ROGC in it), were failing.  Not only were their failing, but they were failing with long and painful latency – in other words, just irk’ing everyone.

With a bit of digging and some investigation with the associated PG’s, we found that when BitLocker was configured on the machine in a site, it would write the recovery key into AD (like we wanted).  Of course, there was only an ROGC in the site, it needed a writeable, so the client went out of site and wrote the attribute.  Of course, BitLocker is one of those things that you always want to make sure you have the key for, right?  So in an attempt to be safe and secure (not to mention, recoverable), the BitLocker process then reads the key back from the DC to make sure that it was written.  Makes sense, but you can see what happens here – The attribute was written to a (full)DC in one site, and is read from the ROGC in the local site – which hasn’t replicated in the change.  Ooops.

So after batting this around a few times, here were some of the suggestions:

-  Before configuring BitLocker, run a script that sets the siteName registry key to a site that has a writeable DC
-  Rehome the subnets for the sites which are going to deploy BitLocker to a site which has a full DC for the domain, and then move them back
-  “Install this patched version” so that the BitLocker installation behaves better

It’s pretty obvious, the first and second are essentially hokey workarounds to a problem, aren’t anything that will scale to an enterprise deployment by any means, and/or solve the immediate need, but don’t take into consideration the ongoing effect of machines coming up in the site.

Instead we have been “testing” out a pre-release patch for this problem, and it’s working great.  Until it’s released, if you run into this problem, you’ll need to do one of the first 2 options above.  But it’s probably still worth a call to your local Microsoft guy to let him know that you want the patch.
