Keep software up to date.
We've seen that an
unprotected PC connected to the internet will become infected in a matter of
minutes. Before you go online, there are a few things you have to do to make
sure your machine and information aren't easy targets for a cyber
attack.
Nothing can guarantee your computer's security 100 per cent, but
you can ensure that you don't make it easy for those looking for a way
in.
Here is a top five must-have list for your computer before you head
online. But it isn't enough to keep your machine safe in this constantly
evolving internet environment. Following the top five is a list of "safe
practices" to help minimize the threat to your machine and
information.
Install anti-virus software and update
regularly.
There are viruses, Trojan horses and worms out there
that change day to day. One of the biggest mistakes people can make after
installing an anti-virus software is assuming their computer is now
safe.
An outdated anti-virus is no protection at all.
The program
has to be updated so that it can recognize new variants of existing viruses. You
can configure your anti-virus software to boot automatically on start-up and run
at all times.
Viruses, worms and Trojan horses are different. Good
software will protect you from all of these but you should make yourself aware
of what your software can and cannot do if possible.
Virus Myth
Mac users don't have to worry about
viruses.
False. While most viruses and exploits are targeted at Windows
applications, Mac viruses – though rare – do exist.
While older Macs are
susceptible to viruses just like PCs, they tend to get far, far fewer, according
to CBC technology columnist Tod Maffin. There are only about 50 Mac viruses
known, compared to more than 85,000 for Windows PCs,
OS 10, the most recent operating system for Macs, has never had a virus,
Most Windows viruses and worms come in the form of e-mail. Mac users can
pass these on to those using Windows. Though your Mac may remain untouched,
those using a PC can become infected.
Macintosh users can no longer take
security for granted. Just like their PC counterparts, they need to be proactive
against online threats.
Install a firewall.
A
firewall acts as a barrier between your home computer and the internet. It can
help screen out unauthorized access and can log attempts to enter your system.
For home users, a firewall can be a software program running on the computer, a
hardware device that plugs in between your modem and your computer or network,
or a combination of both.
A firewall will help protect you from inbound
attacks, but they can do little or nothing to detect e-mails containing viruses
or block spyware and adware – programs that can send data from your computer to
the outside world.
Keep your operating system up to date.
Download
security updates and patches for operating systems regularly. The popularity of
Windows has made it a prime target for hackers – regular updates is a
must.
Security holes in a program may expose your computer to outside
threats. Check for latest vulnerabilities and patches. You can also set your
operating system to update automatically.
Spyware
scanners
Spyware is a general term for programs that could
monitor your computer use, or look for personal data stored on your computer. It
can be installed on your computer without your knowledge, sometimes through free
programs downloaded from the internet, or peer-to-peer file sharing.
Some
spyware can hijack your home page or redirect your web searches. Others cause
pop-up ads out of the blue. At the very least, these programs slow down your
computer, and at their worst, other types of spyware can record a user's
keystrokes and gain access to passwords and financial information.

section.
Secure wireless network
Not securing
your wireless network is akin to leaving your front door wide open for anyone to
walk in. Even if you have a firewall, but do not protect the wireless end of
your system, anyone will be able to access your computer or
network.
Someone with malicious intent can use your internet connection
to attack other systems, or download illegal material such as child
pornography.
You don't pay
good money to have your machine ruined by internet infections.
