How
do I protect myself from Hackers?
|
| There
is no surefire way to prevent 100% of hacker
attacks. The best, and easiest option
we have found as of yet is to put your
computer behind a firewall and run an
antivirus program.
We have had best luck with
the Linksys series of products. In
general, every Cable/DSL router will have a
Firewall built into it. The trick is
that you have to buy one and put it between
your computer and the internet!
We have various options
for internet protection available in
house. If you're interested in a
solution, please call one of our technicians
and they will gladly suggest a solution that
fits your needs.
Alternately, if you are
running Windows XP you can turn on the
built-in Internet Connection Firewall (ICF)
simply by following these steps:
- Open Network
Connections
- Click to select the
Dial–up, LAN or High–Speed Internet
connection that you want to protect
- In the task pane on the
left, under Network Tasks, click Change
settings of this connection as shown
in Figure 5 below.
(Or, within the Network Connections
folder, right-click on the connection
that you want to protect and then click Properties)
- On the Advanced
tab as shown in Figure 7 below, under Internet
Connection Firewall, select one of
the following:
- To enable Internet
Connection Firewall (ICF), select the Protect
my computer and network by limiting or
preventing access to this computer from
the Internet check box.
- To disable Internet
Connection Firewall, clear the Protect
my computer and network by limiting or
preventing access to this computer from
the Internet check box. This
disables the firewall, your computer and
network are then vulnerable to
intrusions.
NOTE: The ICF is not as
effective as a hardware firewall, for better
protection we suggest using a hardware
firewall in conjuction with ICF and an up to
date antivirus program.

| What
types of passwords should I use? |
|
Your password is the key to
your computer -- a key much sought-after by
hackers as a means of getting a foothold
into your system. A weak password may give a
hacker access not only to your computer, but
to the entire network to which your computer
is connected. Treat your password like the
key to your home. Would you leave your home
or office unlocked in a high crime area?
Here are some simple
guidelines for strong passwords.
- It should contain at
least eight characters.
- It should contain a mix
of four different types of characters --
upper case letters, lower case letters,
numbers, and special characters such as
!@#$%^&*,;" If there is only
one letter or special character, it
should not be either the first or last
character in the password.
- It should not be a
name, a slang word, or any word in the
dictionary. It should not include any
part of your name or your e-mail
address.
- You should be able to
type it quickly, so that someone looking
over your shoulder cannot readily see
what you have typed.
- It should be changed at
least every 90 days to keep undetected
intruders from continuing to use it.

| What
are Trojans? and why are they not as fun to
have as I may think? |
|
Named
after the famous Wooden Horse used by the
Greeks to
conquer the city of Troy, these programs
basically invade your PC disguised as a
piece of desirable software. Often hidden
inside the installation routines of pirate
software downloaded from the internet they
install themselves at the same time as the
actual application and modify your system
settings to ensure they are automatically
run every time your PC is started up.
Trojan
horses themselves seldom damage the system
they infect, preferring to silently allow
attackers to access your machine over the
internet and do almost anything from
stealing your files through to destroying
your hard disk. Because they normally rely
on an internet connection, PC's with cable
modems or other always-on connections are
especially vulnerable if infected with a
trojan horse.
Trojans are removed by
AntiVirus software. While there are
manual ways of removing them, we recommend a
more sweeping action by scanning your entire
system at once.
Once you have installed an anti-virus
software program, have the software do the
following:
- Update the software via
the Internet
- Scan all files and
memory on all of your hard disks
- Set the program to scan
floppy disks and downloaded files

is up-to-date. If your software is not
up-to-date you must pick and install

It
important to make sure that any other
programs that are on your computer are up
