Security on the Network and the Internet
Revised February 20, 2008
When it comes to
security on the network, Harford Community College takes it very seriously.
All computers on campus are patched and protected with new updates/antivirus
software as they are released. The college also has security
devices and procedures in place to ensure that your information is safe, and
systems are protected.However - YOUR HOME COMPUTER
COULD BE AT GREAT
RISK.
According to Swedish security company Sophos,
50% of unpatched and
unprotected systems will
be infected with
malicious code within 12
minutes of being
connected to the
Internet.
Here are a few simple steps you can take to help protect your computer
at home:
- Patch your operating
system.
Download and install all available patches and service packs by
connecting to Windows Update.
-
Install a firewall.
Windows XP comes with a
basic firewall, and if
you are running Windows
Vista, it does come with
a more robust firewall
(Windows Firewall) than
XP, as well as
anti-spyware utilities
(Windows Defender).
However, the consensus
is; third party
applications are usually
more effective. Keep in
mind that the XP
firewall offers only
minimal protection.
There are a number of
free firewalls that are
worth considering. The
following are two that
do the job particularly
well.
Comodo Firewall
(www.comodogroup.com)
The definitive free
firewall, Comodo
Firewall protects your system by defeating hackers and restricting
unauthorized programs from accessing the Internet.
ZoneAlarm (www.zonelabs.com)
The free version of
ZoneAlarm lacks the
features of ZoneAlarm
Pro’s firewall. Its program control asks you regularly whether to
allow programs; for some this can be intrusive and annoying. But
it’s been around forever it seems, and it can’t be shut down, or
out, by mal-ware.
- Install anti-virus
software. There is
no doubt that an
unprotected computer
will become infected by
viruses and malware
within minutes of first
being connected to the
internet. There are many
free versions of
anti-virus software
available and the
programs that have a
well justified
reputation are listed
below.
AVG Anti-Virus Free
Edition (www.free.grisoft.com)
Similarly, this program scans files on access, on demand, and on
schedule. Scans email; incoming and outgoing. For those on Vista,
your in luck, it’s Vista-ready.
avast! 4 Home Edition (http://www.avast.com/)
This anti virus app
is a real fighter,
scanning files on demand
and on access, including
email attachments. Let’s
you know when it detects
mal-ware through its
shield function. An
important feature is a
boot-time scan option
which removes mal-ware
that can’t be remove any
other way.
- Install Spyware
and Adware Software.
It’s not only a virus
that can put your
computer down for the
count, but a multitude
of nasties freely
floating on the
Internet. Listed below
are a number of free
programs that offer very
good protection against
malware.
SpyCatcher Express (www.tenebril.com)
SpyCatcher does a
good job of cleaning out
spy-ware and at stopping
further infestation.
Ad-Aware 2007
(www.lavasoftusa.com)
Many software
reviewers consider
Ad-Aware 2007 Free as
the best free spyware
and adware remover
available. It does a
relatively good job of
protecting against known
data-mining, Trojans,
dialers, malware,
browser hijackers and
tracking components. The
only downside with the
free version is
real-time protection is
not included.
WinPatrol (www.winpatrol.com)
Do you want to get a
better understanding of
what programs are being
added to your computer?
Then WinPatrol is the
program for you. With
WinPatrol, in your
system tray, you can
monitor system areas
that are often changed
by malicious programs.
You can monitor your
startup programs and
services, cookies and
current tasks. Should
you need to, WinPatrol
allows you to terminate
processes and enable, or
disable, startup
programs. There are
additional features that
make WinPatrol a very
powerful addition to
your security
applications.
ThreatFire 3 (www.threatfire.com)
ThreatFire 3 blocks mal-ware, including zero-day threats, by
analyzing program behavior and it does a stellar job.
If you are now on the
Internet, and you have
not yet taking the
precautions as outlined
above, you are extremely
vulnerable and it is
critical that you take
the following
precautions:
Stop surfing the Web and
patch your operating
system. Only then
download the protective
software as noted above,
or software that you are
familiar with that will
do an appropriate job of
protecting your
computer.
Do
not visit any other
websites until you have
done this!
Additional security
precautions:
Establish a password for
the administrator
account. Only you
should have
access to the
administrator settings
on your PC.
Unfortunately, XP
installs with open
access to the
administrator’s account.
Be sure to change this.
Create a new password
protected user account.
Using this account
for your general
day-to-day activities
adds another layer of
protection to your
computer. A user account
does not have the same
all-access permissions
as your administrator
account, and in many
cases this extra layer
of protection will
restrict malware from
gaining a foothold on
your PC.
Good luck and safe
surfing.
