What should I do about Windows XP computers that we need to keep?

7 pointschrisBob8 comments

In our lab we have a collection of equipment where each piece has a dedicated windows XP computer (a Wyko interferometer for example). What is the best way to deal with the end of support for these machines?

The hardware is very expensive to upgrade, and upgrading would basically mean throwing it out and starting over with new equipment.

There is also no path to upgrade to Windows 7.

A possible solution:

- Block all machines from accessing the web, let them access only the intranet;

- Install a lightweight VM with a browser on every machine and use this to access the Internet (for e.g. you could use a VM with a small Linux distro only for browsing the net).

The second solution is probably a good compromise. This will let you browse the Internet if necessary without compromising the physical machine security.

It should be possible that on the same physical machine to allow external network access for a VM and block the other apps from accessing the Internet. You can probably do it from the firewall or use a separate IP for the VM and block all IPs from your router except the IPs of the VMs.

The VM should be used only for browsing the internet.

You could attempt to move to a VM, this'll likely fail. I know a KVM environment should work theoretically but it may not.

If that fails you'll likely need to go with an air gap. Transfer all data in and out via flash drive and run nightly virus scans on host computer and the XP one. If you can't air gap the XP computer. Nightly virus/mal scans, allocate more time for IT preemptively, and maybe prayer?

Weekly/Monthly hard drive images are likely a good idea also.

:.:.:

Also stock pile old hardware for it. Trying keeping a few functional ATA hard drives on hand, spare PCI cards if you need them. In all honesty have 1 or 2 computers that can serve as drop in replacements on failure is likely a good idea.

We don't have extra parts, but the service team does and the machines themselves are getting hard to come by. I tried shopping for a computer with more than one PCI slot recently, and spent days just trying to figure out what is in computers from Lenovo, HP and DELL. That is not an important spec to list anymore.

I will do the math with my boss; a duplicate machine might be a good idea while they are still around.

I would recommend an air gap, disabling autorun, removing the CD hardware, and any hardware used to connect to the internet. You could also remove any other hardware and uninstall the drivers you don't need such as a webcam.

Here is a good article on the Malwarebytes Anti-malware blog for some recommendations: http://blog.malwarebytes.org/security-threat/2014/04/windows...

I would stockpile parts for the machines and take them off the network. If you have enough spares and your computers aren't exposed to outside attacks, I don't see why they couldn't hum along for another decade or two.

If you keep it up long enough, you might even get an article: http://www.pcworld.com/article/249951/if_it_aint_broke_dont_...

I think I will start with just pulling it off the network. People like to be able to easily move the data, but it is probably worth making them use thumb drives now.

And while you're at it- definitely disable every possible autorun option.

keep them non networked, if you are really afraid of xp without support
