Lost and stolen devices continue to be the number one threat to mobile users, so never leave it unattended or lying on a café table – put it in your pocket or bag!

Set the screen to lock after a few minutes of inactivity. Set up a long PIN, password, fingerprint or face recognition.
3. Update it
Always install the latest security updates for your operating system and apps.
4. Get a mobile security app
Security apps like Norton, Sophos or MacAfee will keep your mobile device free from malware and other harmful infections, scan wifi to check it's secure, help you avoid phishing scams, keep your personal data private, and help you find or remotely wipe your device if you lose it.
5. Use apps you can trust
6. Close apps
