Editor's Corner

This week's newsletter returns to the subject of "shadow IT" which we covered previously in Issue #995, Beneath the Shadow of the Cloud. We welcome Tony Gore, an independent consultant based in the UK, who has contributed this week's guest editorial.

You may recall that the phrase "shadow IT" refers to when an employee or department secretly uses cloud services without first getting permission from management to do so. Those who do such things in effect are hiding in the shadows so they can't get caught by management. Of course, as this Dilbert comic strip illustrates, employees often wish they could become invisible to hide from their bosses:

http://www.wservernews.com/go/1411387097442

And now on to our guest editorial by Tony Gore...

Shadow IT revisited

Shadow IT has many more problems than just security, especially for small companies. Take, for example, OneDrive (the consumer version, which is subtly different to OneDrive for Business), Dropbox and Google Drive. In their bid to gain customers, you will find that when the client software is installed on phones, it offers to save your photos to their cloud storage. This sounds good until you realize that when someone sits down in the office and connects their PC/laptop/tablet that is also connected to those accounts, a number of hidden potential problems arise:

  1. New content is synchronized. That may sound OK, but when 10 people switch their PCs on at roughly the same time on Monday morning with each having taken 200 MB of photos over the weekend, there is an immediate attempt to synchronize 2 GB downloaded. This is much worse if there are any devices that have new content to upload for any offices using any form of asymmetric connection (where upload is typically 10% of download speeds). This is not far off from a DoS attack at the start of the day.
  2. All these "cloud" storage services also provide decent performance by caching locally. This is probably not a problem if your PCs use traditional spinning hard drives, but if for power and performance you have moved to SSDs, then you have probably sized for Windows with the assumption that storage is on a server or in the cloud. That 128 GB SSD soon fills up if there is 10 GB of locally cached emails and 20-50 GB of cached photos. (Office 365 which includes OneDrive for Business allows 50 GB if email with cached Exchange mode if you use Outlook, and 1 TB of OneDrive cloud storage for each user, and this is before you start sharing OneDrive storage). Of course, you can manually configure the OneDrive storage to be on another disk, but there is a catch as we'll see next.
  3. This is all OK until you have a problem. There are tools to repair your cloud storage when it fails to synchronize. What do you think these tools do? They (a) backup the cached content you have to be on the safe side (a lot more of that SSD bites the dust) and then (b) download all the "cloud" content to ensure that you have a correct copy, checking for any differences with the local backup (a lot of your bandwidth temporarily bites the dust). Has anyone spotted another snag here? Well, if the content has been put on another drive, things go wrong, and the user then does a repair on the installation, the client software might reset itself to the default storage location, which of course does not have any of the content on it, so the entire "cloud" content is re-downloaded.

Now things might not be quite as bad as this IFF (IF and only iF) you know what you are doing. OneDrive for instance has some settings where you can check which folders it synchronizes so you can stop OneDrive from copying all your pictures that your phone automatically uploaded to the cloud by unchecking those folders. But how many normal users know this or how to do it?

And there is another nice little trap for system administrators. All those synchronized photos from phones that end up on the office machines are OK if they are photos of innocent things like flowers and trees, but the photos of the baby in the bath, not to mention some other photos that people might take, how should I put it...should really remain private? And what if you have an interest in bridges or buildings? A few years ago in the UK people were being flagged as potential terrorists for taking photos like that.

While on the phones and the office PCs such photos are effectively behind closed doors. But in between, they are sitting in the cloud, and some clouds are more public than others and may well have image crawlers working their way through them, not necessarily to publish but rather to check content. And if the authorities take an interest in these photos, how long before they turn up at the office to take a look at what else their might be on the office computers?

I have ignored here all the easy ways in which data might leak out since people expect that to be a risk. It is the way in which simple things can expose you to problems that you might not have thought of that we're exploring here.

Don't get me wrong however, cloud storage and synchronized content are very useful tools, and I have slowly been using them more and more over the last two years, looking to see what the strengths and weaknesses are. But that is how I have come across some of these hidden gotchas.

For me, the greatest benefit has been from using OneNote with notebooks stored in the cloud (they can also be stored locally or on local servers). I have one very specific use for this: I often have to take meeting minutes whilst travelling. Breakdown and theft of my laptop is a high risk because the meeting cannot be reconvened. Not only would loss of this material have security implications, but at the very least it could result in me not fulfilling a contract and not getting paid, and I might have significant travel expenses as well as days of time at risk. So I take my notes directly into OneNote and if at all possible with an Internet connection so it is continually synchronized to the cloud. Before leaving the meeting, I then check it in OneNote on my phone. If it is there, I know it has been replicated through the cloud and back down to my phone. And yes, all my devices can be tracked in case of loss/theft and remotely wiped by a number of different methods. While this still poses some risk, we should remember that you cannot remotely wipe notes written down on paper, so let us keep things in perspective.

In conclusion, shadow IT brings both new risks and new benefits, and at the end of the day we all need to make the best we can of the benefits while minimizing the risks. This poses challenges for IT administration, but the IT world has never stood still, and if many of us are honest, it is this challenge that gets us out of bed in the morning most of the time.

Tip of the Week - Passwords that never expire

This week's tip is by Roan Daley, a Premier Field Engineer at Microsoft.

Finding Active Directory objects that have Password Never Expires

As an Active Directory PFE, one of the issues I typically address with administrators is to identify objects (computers or users) that have Password Never Expires. From security perspective, this is considered a risk. For most environments, the easiest way to do this is to use the DS query command:

For Users:

dsquery * domainroot -filter "(&(objectClass=user)(UserAccountControl:1.2.840.113556.1.4.803:=65536))" -attr sAMAccountName userPrincipalName userAccountControl -d contoso.com

For Computers:

dsquery * domainroot -filter "(&(objectClass=computer)(UserAccountControl:1.2.840.113556.1.4.803:=65536))" -attr cn userAccountControl -d contoso.com

For Window 2008 R2 and above this is even easier with the advent of the Active Directory PowerShell Modules:

For Users:

Search-ADAccount -PasswordNeverExpires | FT Name,ObjectClass -A

For Computers:

Search-ADAccount –PasswordNeverExpires - ComputersOnly | FT Name,ObjectClass –A

Hope these tips help with keeping you AD Clean!

Botnets creating security bugaboos for cloud users

Lots of cloud users are unaware of botnets, and many of those who have heard the term don't actually know what a botnet really is. As such, they are inadvertently allowing for opportunities for botnet cloud attacks – and thus becoming cyber attackers themselves. Educate yourself on the risks and behaviors of botnets, and minimize the risk of them striking through your systems.
