Secure Delete

Automation, Desktops, General Interest, Scripting, Security October 29th, 2007

I caught this one recently on an episode of CyberSpeak (10/15 show)…..

There are a lot of “secure” file deletion applications out there, but these two look quick and simple and can be used on-the-fly from a thumb drive or automated in a script.

SDelete from Sysinternals/Microsoft

Cipher (included with Windows 2000 and above)

Assuming you do the right thing and migrate all of your confidential data to an encrypted TrueCrypt volume, what do you do with the old copies of the data? You can securely erase the data using these tools so that the only recoverable copy is in your encrypted volume.

Some systems use a data interchange folder to integrate two disparate systems. One system will drop an export file in the directory and the other system will import the file from the directory. I’ve seen POS systems integrate to credit card processing systems in this manner. With this tool, you can script a cron job to regularly securely delete the interchange files in the directory.

Just another layer of security to consider.

Microsoft Patches

Automation, Desktops, Patches, Scripting, Security April 25th, 2007

A quick note on a couple of recent Microsoft patches that you might find relevant.

If you have installed the Microsoft MS07-017 (KB925902) patch and had a problem with your systems receiving the following errors:

application_executable_name – Illegal System DLL Relocation

The system DLL user32.dll was relocated in memory. The application will not run properly. The relocation occurred because the DLL C:\Windows\System32\Hhctrl.ocx occupied an address range reserved for Windows system DLLs. The vendor supplying the DLL should be contacted for a new DLL.

Check out the following MS Knowledgebase article and related patch.  I’ve downloaded the patch and applied it successfully to my systems with the Realtek Audio software.

MS Knowledgebase Article 935448

Update for WindowsXP (KB935448)

I use the Kixtart scripting language for my login scripts, so it was easy to deploy the original patch as well as the follow-up Realtek patch using the following script:

AT ( 1,1) “A critical security patch is needed on your computer.”
AT ( 2,1) “Please wait while your system is updated……..”

IF EXIST (“C:\WINNT\$NtUninstallKB925902$”) OR EXIST (“C:\WINDOWS\$NtUninstallKB925902$”)
             AT (4,1) “Microsoft Exploit Patch already applied”
             IF EXIST (“C:\WINNT\$NtUninstallKB935448$”) OR EXIST (“C:\WINDOWS\$NtUninstallKB935448$”)
                          AT (6,1) “Realtek Patch Already Applied”
                          IF @producttype = “Windows XP Professional”
                              AT (6,1) “Installing Realtek Patch…..”
                              SHELL “\\DOMAINCONTROLLER\NETLOGON\PATCHES\KB935448.exe /QUIET /NORESTART”

             if @producttype = “Windows 2000 Professional”
                AT (4,1) “Patching Windows 2000 Professional…….”

             if @producttype = “Windows XP Professional”
                AT (4,1) “Patching WindowsXP Professional……..”

AT (8,1) “Your system has been patched.”

Hopefully you find this useful. 

Oh, and if you are not using a robust scripting language, you should check out KiXstart.  It’s released as CareWare, so please do your part and make a donation to one of the listed organizations.

A Nice Surprise

Desktops, Vendors March 13th, 2007

First, let me tell you that this comment is out of character for me (just ask my wife).  I tend to be very cynical and do not toss out compliments like this very readily.  I recently purchased a quantity of desktop computers at work and I have to give Gateway credit on their initial software load.  I had been expecting to find a ton of preload junk on the systems that I would have to uninstall or force me to start from scratch to build an image.  Given my experience with other vendors, I expected I would need to de-crapify the system before it’s usable or to prevent dealing with a dozen ‘courtesy’ subscriptions expiring and consuming resources to remind you to hand over your credit card.  However, I only found three items that needed removal; a browser error re-director, Google toolbar and Symantec AntiVirus.  (Only to load our own licensed copy and prevent problems with the free subscription expiring).  Yes, some de-crapifying had to be done, but nowhere near what I expected.

I guess I was so surprised at my good fortune given the way the PC industry is these days.  I don’t know if any other vendors are planning to follow suit, but I certainly hope so.
