Protecting your personal devices in shared or public spaces prevents physical tampering and localized data interception before you ever log into your accounts.
- Keep your apps up to date: Turn on automatic updates for the apps on your phone, tablet, and computer. App updates do more than add security features, they also fix hidden security bugs. Keeping your apps updated makes it much harder for hackers to sneak in through an old weakness.
- Back up your important files (3-2-1 Rule): Keep 3 copies of your important documents and photos, stored on 2 different types of media (like your computer and a cloud service), with 1 copy kept completely offline. If your computer breaks or gets locked by a scammer, having an offline copy makes it harder to lose your family photos, tax records, or important financial files.
- Secure your home Wi-Fi network: Change the default password on your home Wi-Fi router and make sure your network security is set to WPA2 or WPA3 in your settings. Routers come with generic factory passwords that hackers can discover. Putting a strong, custom password on your router locks your home network so bad actors can’t access it.
- Avoid using public USB charging ports: Plug your phone charger into a regular wall outlet or use a portable power bank instead of plugging directly into public USB slots at airports or stations. Scammers can tamper with public USB ports to secretly download your information while the device charges.
- Turn off “Auto Connect” for public Wi-Fi: Go into your phone settings and switch off the feature that lets your device automatically join open Wi-Fi Scammers often set up fake Wi-Fi networks to trick nearby phones into connecting.
- Turn off Bluetooth in crowded places: Switch off your Bluetooth when you aren’t using it in busy public areas like malls, airports, or trains. Leaving Bluetooth on makes your phone visible to nearby strangers, giving bad actors a potential doorway to send unwanted files or try connecting to your device.
