Using public computers
Is it safe to use public computers?
There are countless public computers offering internet access. Most of these are set up so that no-one can install spyware or change settings. In theory, this means public computers should be safe, but there remains the potential for abuse, so it’s wise to take care.
Many people connect using laptops to online public wireless networks, which are not as secure as those in the home or workplace. It is advisable to limit activities, such as online banking or transactions using credit cards, and to ensure that security software, such as anti-virus and anti-spyware software, and a firewall, are installed on the laptop.
How can I keep my details private when using a public computer?
To maintain your privacy when using a public computer, opt for a reputable location such as a computer at a public library, hotel or computer store. Check to see what security is installed. If the system does not automatically clear your personal settings after use, ask the provider if you can reboot the computer when you’ve finished, to help clear your tracks.
Just as you’d never leave your credit card lying around, it’s also important to keep personal details and passwords secure. Criminals may loiter near public computers in an attempt to pick up personal details, so it’s wise to be alert. Remember that someone using a mobile could be filming your fingers on the keyboard.
Remember to never leave a public computer unattended at any time until you are fully logged out.
Don’t save any files or any log-in information. Log out of any sites you visit and if there is an automatic log-in checkbox, uncheck it to prevent others logging in with your identity later.
There is always the risk that any public computer will have a keylogger or other form of spyware installed, recording details and passwords. Because of this, any online banking or credit card transactions should be avoided when using a public computer.
When you’ve finished, clear the history, quit the browser, log out and, if possible, reboot the computer.
