Online
security is becoming a bigger concern as the Internet increases
in popularity and more hackers attempt to invade people's computers.
Internet
security is a very real problem
and there is no doubt that if you have done nothing to protect
your computer you are in real danger of
being hacked. We can't stress enough the importance of
online security for Internet users.
The Source of the
Problem
Aside
from the real source of the problem - malicious acts of hackers
- a big part of the problem is Internet users using PC's to access
the Web with a version of Microsoft Windows installed as the operating
system. New vulnerabilities in Windows are discovered regularly.
While Microsoft continues to release new security patches the
patches are created after a new hole has been discovered, and
not everyone keeps as up to date with these releases as they should.
Windows
has proven to be so vulnerable because the operating system was
originally written with the idea that it would run on a stand-alone
computer or possibly as part of a friendly, self-contained local
area network. The Internet and related services are all things
that have been added onto the original code.
As
of 2004 Microsoft is supposedly working a new operating system
that is being written from the ground up and has security as one
of its top priorities. We will have to wait until it has been
released and is installed on people's machines to see if they
have successfully created a truly secure OS.
In
the mean time you check Microsoft's
Security Advisor Site.

Solutions
Secure
Operating Systems
One
solution that people have adopted is alternative operating systems
such as Linux, which runs on industry standard PC's, or the Apple
Mac OS. These operating systems have fewer security problems than
MS Windows because they are both based on Unix which was written
from the outset with intention that it would run in large multi-user,
networking environments. While these UNIX based OS's have fewer
security problems than Windows, they are not hacker proof.
Software
Protection Utilities
Another
solution is to add software utilities such as 'Firewalls' and
'Intrusion Detectors'. Firewall software has the advantage of
being able to protect your computer from both external invasion
hacking and the internal transmission of private, personal data
that may take place if your machine has become compromised by
a trojan horse or spyware or become infected with a virus.
The
XP version of Windows comes with a built-in firewall that does
a good job of protecting the PC against inbound hack attempts,
but it does nothing to protect the computer against outbound connections
that may take place . You still need a third-party firewall for
this.
Some
of the better know third-party firewalls are from Symantec/Norton
and McAfee. Online
security software firewalls - latest versions can be found here.
Hardware
Security Devices
The
most common hardware Internet security devices are the little
external firewall and NAT router/switch boxes. These devices provide
the best possible protection from external hacking. They stand
as drive-less, non-corruptible computer between your computer
and the Internet. They have the added benefit of easily sharing
a single Internet connection between several machines.
Even
in homes with just a single computer but multiple users they make
an excellent security investment because they are relatively inexpensive
and none of the home computer users can unwittingly and unknowingly
disable its protection as might be the case with a software only
solution.
The
one thing that these devices cannot do is protect your machine
against outbound connections that originate from within your computer
from a Trojan horse, spyware, or a virus.

Recommendations
In
our view the very best Internet security protection comes from
combining an external hardware firewall/NAT router/switch with
an additional software firewall running on every PC that has Internet
access.
