Cyber Made Simple — week 20 2026-05-11

What happened this week

Cyber threats do not take a break, and this week's reading covers some of the most practical ground a small-business owner can cover: keeping your devices and network locked down, understanding how encryption actually works, and a fascinating look at how even the aviation industry wrestles with the same kinds of digital risks you face every day.

Top picks

• Why You Should Never Share Your Personal Device or Home Network — A clear reminder that handing your phone or Wi-Fi to a stranger is like handing them your front-door key. Well worth five minutes of your time.
• A Simple Guide to Encryption — No jargon, no fuss. This explains what encryption is, why it matters, and how to switch it on using tools already built into your computer.
• Cybersecurity in Aviation: Protecting Air Traffic Control and Flight Operations — A broader look at how critical industries defend their digital systems, with lessons that translate surprisingly well to smaller organisations.

What to do next

This week, take ten minutes to check whether encryption is switched on for your work laptop or desktop — on Windows, search for BitLocker in the Start menu; on a Mac, go to System Settings → Privacy & Security → FileVault — and if it is off, turn it on now.
