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outdated anti-virus is no protection at all.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.

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.
