Recently Two ISPs were taken offline by thier upline service providers, thus rendering part of the Zeus Botnet's Command and Control service inoperable.  However even taking 90 of the 250 command and control nodes offlinue did not stop the opreation of the Botnet on the internet.

Imagine if you will that more than 30% of the controls for your Internet business suddenly disappeared.  Would you expect that your business would be able to continue?  If you think that I am admiring the operations that the Hackers employ in developing thier business models, you would be right.

You see that have built redundancy into thier business model like no one else has been able to employ.  Again, 1/3 of thier command and control assets were eliminated, but they planned ahead, and thier operations still continued to operate.  There is a leason that all of us can learn.  Without proper planning, any number of things could wipe out your operations, and leave your business without the necessary support that it needs to continue.

It doesn't matter if your business is on-line or in-house.  Proper Planning will ensure that your business can continue operations, while the missing links are replaced to thier previous operation.  I have posted the rest of the story for the Zeus botnet here on my Company's website.
