Ethernet
is a long-established networking standard, and ethernet equipment
is cheap and easily available. Ethernet does require running new
cabling to each computer you need to connect to the network. Some
other alternatives are available which use carry signals using
radio waves, power cables or phone lines within the home: Wireless
Ethernet (WiFi), HomeRF, and HomePNA. We don't particularly recommend
those standards for home networks - there are problems with security,
coverage, different standards, cost and availability of equipment.
A future guide will cover adding wireless Ethernet to complement
an existing network. Currently we think a standard cabled ethernet
network is the best solution for most people.
By connecting your machine to
the residence hall network you have become a member of several
communities. The residence hall network, the campus network, and
the global network. As such you have a social responsibility (though
one you can choose to not fullfill) to protect the groups well
being. A good reason for an intruder to gain access to a res-hall
machine is to use it as a launching platform to attack other machines.
It is very common for network intruders to take control of sever
machines like this and route their traffic through them in order
to make a trace back more difficult.
To set up a home network you
need to understand what function each piece of equipment performs
so you can connect them together correctly. The jargon used can
be confusing, but this glossary and diagram describes the key
equipment and what it does.
Note that while these components
are described and illustrated separately for clarity, in practice
you can often buy one box which combines two or more functions
(for example a router will often include a built-in switch too).
There are those who believe that
the security issues facing home users are greatly exaggerated,
and that the only entities which need to be concerned about desktop
and network security are businesses which have critical data on
their machines. And many think that only broadband users or folks
with high-speed connections need to be concerned.
Truth is, the vast majority of computer systems,
including corporate ones, are not compromised for the data they
may contain. Rather, they are often compromised for practice purposes,
such as storage space for warez, or to create remote zombies for
large-scale Distributed Denial of Service (DDoS) attacks against
other networks. Compromised systems today are even being used
to send SPAM.
Most systems are not necessarily compromised
by a dedicated cracker trying a variety of remote commands until
he/she successfully cracks the system password. Instead, most
attacks today are performed using automated tools which attempt
to exploit known vulnerabilities in various OSes and applications.
If you are experiencing computer
problems and you are in need of repair, we can send you a computer
technician to help you with troubleshooting your computer problem.
We understand that new technology can be confusing, and if you
require help installing the latest technologies onto your computer
then we are your consultants. |
