Q. Can a virus survive a reimage?
A. A virus could only survive reimaging if it had infected the boot sector and the reimaging process did not overwrite the boot sector with a clean one.
Q. Can a computer infect the image server during reimage?
A. The computer, while being reimaged, are not booted into the OS. There is no way for them to infect the license server because their code is not being run.
Q. Could a virus be brought thru a reimage?
A. The only way a virus could be brought through an image is:
- the image has a virus
- You didnt overwrite the boot sector
Making sure (1) didn’t happen is easy. Making sure (2) didn’t happen is just a matter of making sure your software handles boot sectors appropriately. Make sure your software (generally linux boot cd) zero’s out /dev/hda (sda if its SATA), and THEN image.
Conclusion:
I don’t know of a virus that effects ghost images/zen images/clonezilla images. Keep your base machine off the network and only connected to the image server. Make sure the image server is a read only source to the infected network (though, thats how all of these products work unless you explicitly tell them otherwise). Firewall off absolutely everything you dont need open (simply out of preparedness). Then image away.
Again, there is no way to infect the image “on-the-wire”.
