Cyber Made Simple — week 20 2026-05-11

What happened this week

Two useful guides landed this week covering some of the most practical ways you can protect yourself at home — one looking at the risks of sharing your devices or Wi-Fi with strangers, and another breaking down how encryption works in plain English. Neither topic makes the headlines very often, but both affect everyday home users more than most people realise.

Top picks

• Why You Should Never Share Your Personal Device or Home Network — A clear reminder that handing your phone or laptop to someone you don't know is a bit like handing them your house keys. Well worth a read if you've ever let a stranger borrow your Wi-Fi.
• A Simple Guide to Encryption — Encryption sounds complicated but your computer almost certainly already has it built in. This guide explains what it is and how to switch it on without any technical know-how.

What to do next

Check whether encryption is switched on for your computer's hard drive — on Windows, search for BitLocker in the Start menu, and on a Mac, go to System Settings, then Privacy & Security, and look for FileVault. If it's off, turn it on. It takes just a few clicks and means your files stay protected even if your device is ever lost or stolen.
