Chapter 12 - Virus Attacks
Exposure to Viruses
It can be difficult for most people to imagine
just how much disruption was caused by the Slammer worm described in
the previous excerpt. A real world example might help put the
severity of the attack in perspective. Imagine traveling along a
major thoroughfare at the height of rush hour traffic. Now imagine
that all at once, cars begin to be disabled, and within a very few
minutes one out of every five cars on the road is either dead or
dying. At this point, all bets are off, nobody is going anywhere.
The four out of five cars that are running properly will be
hopelessly entangled in a web of disabled vehicles and the whole
system will grind to a speedy and ugly halt.
On the Internet, data packets are the cars, and
the network is the highway. With one out of five data packets
affected, it is impossible for the remainder of system to function
properly. When a problem of this magnitude develops, there are
consequences. The network administrators and IT professionals that
might otherwise quash a problem before anyone else takes notice, are
quickly overwhelmed.
The resultant back-up overflows out into the
real world and things start to happen. Airline scheduling
systems fail; telephone networks falter; financial and banking
institutions shut down and no one gets their daily double raspberry
cappuccino with their debit card.
While virus attacks are prolific; this chapter
will present information on some other lesser known types of attacks
that can be just as destructive. These include computer worms and
the Trojan horse. The similarities and differences in those types
of attacks will be examined and information about how computers can
be protected from attack will be included.
