International Computer Security Day

Top tips for computer security

For International Computer Security Day, Selmar is presenting top tips for maintaining your safety while using computers. Celebrated each year on November 30, Computer Security Day was started in 1988 to remind people to protect their computers and information and raise awareness of computer related security issues.

External surrounds

Computer safety isn’t just about data protection! Keep the environment around your computer safe by using non-slip mats and anti-shock protectors. Power surge protectors are vital to ensure your computer is not affected by sudden electricity faults. Avoid spills by keeping liquids such as cold drinks or coffee away from your computer.

The word on passwords

It’s tempting to use a simple, easy to remember password – but basic passwords are actually really insecure. To ensure your password does what it’s meant to and keeps people out, remember:  

  • Don’t use personal information such as your name, birthday or other publically available information
  • The longer the password the better
  • Use a combination of letters, symbols and upper and lower case letters
  • Passwords need to be regularly changed
  • Don’t use the same password for all of your accounts
  • Using a password generator can help with creating a unique, strong password. To remember your creation, you can use a word trick to the password, for example: T&br46d = Capital T and little b run for six days
  • You could write down your passwords but keep them somewhere secure and away from your computer and wallet. Coding your passwords might also work

Update your software

Keeping your computer’s operating system and programs up to date is the best way to avoid security vulnerability.

Make sure your anti-virus software is also current. As well as preventing computer viruses and malware, it can protect your identity and help stop online shopping fraud.

Shop smart online

It’s a good idea to check the reputation of the store before you purchase from a new site. Checking the store’s policies for privacy, returns and non-deliveries is smart.

A quick search will provide reviews and checking the URL in the browser matches the site name can prevent falling into the trap of online fraud.

Know your spam

Check out how to recognise scan or hoax emails and websites and keep up to sate with the latest scams via the Australian Government’s Scamwatch.

You could also learn about pretexting. This is when scammers pretend to be someone they are not, such as a bank or telephone company, to access your personal data.

Back up

If you don’t regularly back up your computer and devices, why not make today the day you start? You can back up to a USB, hard drive or cloud and set regular back-up reminders to ensure your work is always safe and protected.

Outside the office

A computer, phone or tablet left in plain sight in your car is an open invitation to thieves. Chances are, you will be missing your electronic device and a car window when you return.


At the end of its life with you, be sure to wipe the data from your computer before sending it to a second life at a local school or recycling centre.
