We already talked about VPNs. But data security goes deeper. If your laptop gets stolen, can the thief access your bank account?
Here is How to Secure Your Data While Using Public Wi-Fi.
1. HTTPS Everywhere
Install the “HTTPS Everywhere” browser extension. It forces websites to use the secure version. Never enter a credit card number on a site that says “Not Secure” in the address bar.
2. Turn Off File Sharing
Your computer loves to share. “AirDrop” or “Windows Nearby Sharing” broadcasts your existence to everyone in the cafe.
Turn these OFF when you are in public. Only turn them on when you need them.
3. Encrypt Your Hard Drive
Mac: Turn on FileVault.
Windows: Turn
on BitLocker.
This means if someone steals your laptop and pulls out the hard drive, the data is scrambled. Without your password, it is useless.
Kiran’s Take: The Privacy Screen
The biggest hack is simple: Someone looking over your shoulder.
Buy a $20 “Privacy Screen Filter” for your laptop. It makes the screen look black from the side. Only you (sitting directly in front) can see it. It is essential for working on planes.
Conclusion
Paranoia is a virtue when you carry your life in your backpack. Lock it down.
