How Crackers Could Crash The Internet by Nathan Cochrane
[Computers; It Professional]
08/22/2000 The Age 1 Copyright of John Fairfax Group Pty Ltd

AUSTRALIA is a simultaneous attack away from being cut off from the
rest of the Internet.

Excite@Home chief technologist Milo Medin says that if crackers and
cyber terrorists properly understood the Net's construction, they 
would concentrate on  crashing a baker's dozen of file servers 
instead of exploiting vulnerabilities in individual websites.
  Such an attack would crash the Net and cut-off the rest of the world
from Australian businesses, government and private users.

``You wouldn't even be able to access your homepage,'' Medin says.

The Internet's achilles heel is its reliance on a domain-name system
(DNS) that uses root servers, the big computers that hold 
authoritative details of the  world's domains (such as .com, .net, 
.org).

There are 13 of these root servers at the core of the global network's
infrastructure. This network falls under the auspices of the Internet
Corporation for Assigned Names and Numbers (ICANN), an advisory group 
on Internet naming policy.

The central or A server, with its master list, is maintained by a US
company,  Network Solutions Inc, and is replicated daily to 12 others
around the world. These servers are housed mostly in the US, at 
military and educational sites and  NASA, although Japan, Sweden and 
Britain also have one each.
