Device Hygiene

Outdated devices and apps are the easiest entry point for attackers. Small hygiene habits protect your entire digital home.

Why Device Hygiene Matters

Every device you use — smartphones, tablets, laptops, smart TVs, consoles and even smart toys — holds sensitive information and connects to your home network.

When devices fall behind on updates or use insecure settings, they become easy entry points for attackers, malware, fake apps and data theft.

What You Should Know

  • Old apps often keep sensitive data, even after you stop using them.
  • Devices without updates can be exploited in seconds by automated attacks.
  • Fake apps and unsafe downloads are designed to trick both adults and children.
  • Weak device security can expose Wi-Fi passwords, photos, messages and locations.

How to Protect Your Devices

1. Turn On Automatic Updates

Updates fix vulnerabilities. Enable auto-updates for apps and system software on all devices, especially children’s tablets and phones.

2. Delete Apps You Don’t Use

Old apps can leak data or contain outdated code. Remove anything you no longer recognise or need — especially older games and forgotten accounts.

3. Review App Permissions

Many apps request unnecessary access to your camera, microphone, contacts or location. Switch off anything not required for the app to function.

4. Install Apps Only From Official Stores

Avoid third-party sites or “modded” apps. These are a common source of malware and can compromise the entire device.

5. Turn Off Bluetooth & AirDrop When Not in Use

Attackers can abuse wireless sharing features. Keeping them off reduces risk, especially in public places.

6. Enable Screen Locks on Every Device

Use PINs, passcodes or biometrics. This protects sensitive data if a device is lost, stolen or picked up by a child.

7. Restart Devices Weekly

A simple reboot can kill background malware, reset broken apps and force updates to install properly.
