Public WiFi networks can be convenient, but they are also one of the easiest ways for cyber criminals to intercept information. You can still use them safely if you take a few simple steps and know what to avoid.
Where can Public WiFi Networks be be found?
Public WiFi networks are often available in cafes, shopping centres, hospitals, airports and libraries. These networks usually do not require a password, which means they lack the encryption found on private networks.
This lack of security makes it easier for cyber criminals to use specialised software to ‘listen in’ on the data being sent and received by your device.
Things to remember
When using public WiFi networks, here are some things to keep in mind:
Avoid doing anything that exposes your private information. This includes checking online banking, logging in to accounts that store personal details, or making online purchases. These activities can wait until you are at home and safely using your home internet or mobile data.
Look carefully at the name of the WiFi network. Scammers sometimes create fake hotspots with names similar to the real ones. If the name looks unusual or slightly misspelled, choose a different network. If staff are nearby, ask them which network is the correct one.
Auto join networks aren’t always safe. If your phone or tablet offers the option to ‘auto join’ networks, consider turning this off. Devices can sometimes connect to unsafe networks without you noticing. Manually choosing a network gives you more control.
Stay on secure websites. If you need to use public WiFi for general browsing, try to stay on websites that use secure connections only. You can check this by confirming the site address begins with the letters https rather than http (the “s” stands for secure).
Disconnect from the WiFi as soon as you are finished. Leaving your device connected increases the chance of unwanted access in the background.
Is there a safer way to use your device out and about?
A safer alternative to public WiFi is using a dedicated pocket WiFi device, or turning on a personal hotspot from your phone. This creates a private connection that only your device can use. These are more secure options and avoid the risks that come with shared networks.
Trust your instincts
If something about the network doesn’t feel right, or you receive unexpected pop-ups while browsing, disconnect immediately and switch to mobile data.
Staying safe online doesn't mean you have to stay disconnected. By being selective about which networks you join and mindful of the sites you visit, you can enjoy the convenience of the digital world without risking your personal information.
