Safely Using Public Wifi
We're continuing to promote Cyber Security Awareness this month, and today our focus is safely using public wifi. The FTC recommends that to protect your information when using wireless hotspots, send information only to sites that are fully encrypted, and avoid using mobile apps that require personal or financial information. Learn more about wifi security on their website.
Here’s how you can protect your information when using Wi-Fi:
- When using a hotspot, log in or send personal information only to websites 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.
- Consider changing the settings on your mobile device so it doesn’t automatically connect to nearby Wi-Fi. That way, you have more control over when and how your device uses public Wi-Fi.
- 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 get a personal VPN account from a VPN service provider. In addition, some organizations create VPNs to provide secure, remote access for their employees. What’s more, VPN options are available for mobile devices; they can encrypt information you send through mobile apps.
- Some Wi-Fi networks use encryption: WEP and WPA are common, but they might not protect you against all hacking programs. WPA2 is the strongest.
- Installing browser add-ons or plug-ins can help. 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.
