 Keep secure
There
are some key principles to consider to keep your computer or network secure.
They
are as follows:
- Install
and Use Anti-Virus Programs
-
Keep Your System Patched
- Use
Care When Reading Email with Attachments
- Install
and Use a Firewall Program
- Make
Backups of Important Files and Folders
- Use
Strong Passwords
- Use
Care When Downloading and Installing Programs
- Install
and Use a Hardware Firewall
- Install
and Use a File Encryption Program and Access Controls
It
should be remembered that threats to your computer may not just be those
posed online. If your computer were to be stolen, or accessed in your
absence, how hard would it be for the perpetrator to access confidential
information? Does your computer even have a password to log on?
Wireless security
Do
you have a wireless network? Does it have an encryption of some sort or
a network key? So many wireless networks are set up and left open for
anyone to 'walk right into your network and take a look around!' What
you might not realise is that by leaving your network unsecured, you're
leaving your network open to two threats.
Firstly,
anyone can connect to your network and use your internet connection whenever
they please, using up your bandwidth and hence slowing the internet speed
for you and the remaining users on your network.
Secondly,
and far more threatening, they can potentially see every single computer
on your network and any folders those computers might be sharing. Furthermore,
if the security of the folders on the computers on the network is not
set correctly, that intruder can then delete files and folders at will.
Security
measures exist to protect you, your computer, and your network from intrusion.
