Jesper's Blog
Obligatory file photo:
Welcome to Jesper Johansson's blog. This is my home for pontification on the web. In case this is your first time here, I have been working on information security for about 20 years, and have been writing and speaking on the topic for about 10. I am also a
Microsoft MVP
in Windows Security.
My most recent book is the
Windows Server 2008 Security Resource Kit
. Because I am also a scuba instructor you may find some posts related to that topic as well. Just because it took me so long to get it, I also like to say that I have a Ph.D. in Management Information Systems from the University of Minnesota.

Do Vista Users Need Fewer Security Patches Than XP Users?
On January 23, Jeff Jones, Director of Security at Microsoft, published his "One Year Vulnerability Report" for Windows Vista. In the report, he analyzed whether Windows Vista had fewer vulnerabilities in its first year than it's predecessor...
Remotely listing all installed updates
A couple of weeks ago I published a script to list installed updates . Predictably, one of the comments ask for a version that can do that remotely. Here it is . This version can be run a couple of ways. First, you can double-click it. If you do it will...
Using Autoplay on Vista To Stop Attacks
The January issue of TechNet Magazine has an article I wrote about how to hack a system using autoplaying USB flash drives. While it is not possible to stop all attacks from USB tokens, Vista does include some interesting protective measures. However...
WSUS 3.0 Is Still A Memory Hog
This evening I brought my WSUS server up to WSUS 3.0. Mostly I wanted to see if it still was as big a memory hog as 2.0. After the 90-minute-or-so installation was finished, here is what I had: wsusservice: 50 MB IIS worker process: 100 MB SQL 2005 instance...
I've Hit F12 For the Last Time
OK, so whose bright idea was it to put the F12 key so close to the Delete key on the keyboard? And whose bright idea was it to map F12 to "Save As..." in every MS Office application? And, whose bright idea was it to default the Save As... option...
Group Policy Fails For One User
Recently I started noticing a very strange problem. user Group Policy was not applying for a single user. All other users got GPO just fine, but for one user GPO failed to apply. This manifested itself in a couple of interesting ways: When you run gpresult...
New Article: SBS At Home
I've had this love-hate relationship with Microsoft Small Business Server (SBS) for years. On the one hand, I agree to a large extent with Tom Shinder and Tim Mullen that SBS makes security compromises that in many, if not most, businesses are imprudent...
Place offline web pages in the correct zone with MOTW
For several years I have used a homepage in Internet Explorer (IE) that is a list of links I often visit. I find it a lot more convenient than using Favorites to track this, and it is easier to save, move to a new system when you flatten this one, and...

While poking around for a blog post on Susan's blog, I found this one , asking how to wipe a drive. Teacher, Teacher, I know the answer, I know: cipher /w:<drive letter> This command, built into Windows XP and higher, does a three-write pass...
SMB Message Signing Troubles?
Susan posted this a few days ago , and I just thought it made sense to give it some more attention. SMB Message Signing is one of, if not the most, problematic security setting in Windows. It is commonly used to defeat man-in-the-middle attacks, but getting...
