Do you use public Wi-Fi?
Here are some tips to help you protect yourself:
- When using a Wi-Fi hotspot, only log in or send personal information to websites that you know are fully encrypted. To be secure, your entire visit to each site should be encrypted – from the time you log in to the site until you log out. If you think you’re logged in to an encrypted site but find yourself on an unencrypted page, log out right away.
- Don’t stay permanently signed in to accounts. When you’ve finished using an account, log out.
- Do not use the same password on different websites. It could give someone who gains access to one of your accounts access to many of your accounts.
- Many web browsers alert users who try to visit fraudulent websites or download malicious programs. Pay attention to these warnings, and keep your browser and security software up-to-date.
- If you regularly access online accounts through Wi-Fi hotspots, use a virtual private network (VPN). VPNs encrypt traffic between your computer and the internet, even on unsecured networks. You can obtain a personal VPN account from a VPN service provider. In addition, some organizations create VPNs to provide secure, remote access for their employees.
- Some Wi-Fi networks use encryption: WEP and WPA are the most common. WPA encryption protects your information against common hacking programs. WEP may not. WPA2 is the strongest. If you aren’t certain that you are on a WPA network, use the same precautions as on an unsecured network.
- Installing browser add-ons or plug-ins can help, too. For example, Force-TLS and HTTPS-Everywhere are free Firefox add-ons that force the browser to use encryption on popular websites that usually aren’t encrypted. They don’t protect you on all websites – look for https in the URL to know a site is secure.
