How to secure your work smartphone or tablet, and what to do if a device is lost or stolen.

Mobile Device Security

Your smartphone holds emails, contacts, banking apps, authentication codes and access to your cloud accounts. A compromised or lost phone is a major security incident.

Essential Mobile Security Settings

Setting Why It Matters
Screen PIN/biometrics (6+ digit PIN) Prevents access if phone is lost or stolen
Full-device encryption Most modern phones enable it by default. Verify in settings
Remote wipe enabled (Find My / Find My Device) Lets you erase data if phone is lost
Auto-lock after 30–60 seconds Reduces window for physical access
OS automatic updates enabled Patches security vulnerabilities quickly
App permissions reviewed Revoke location/microphone/camera from apps that don’t need them

App Safety

⚠ Warning
Never install apps from outside the official App Store (iOS) or Google Play Store (Android). Sideloaded apps bypass Google’s and Apple’s security scanning and are a primary vector for mobile malware. On Android, never enable “Install from unknown sources” unless you have a specific, verified reason.
When installing an app, review the permissions it requests. A flashlight app asking for access to your contacts, microphone, and location is a red flag.

Smishing (SMS Phishing)

Smishing attacks arrive as text messages pretending to be from:
  • Australia Post / couriers (“your parcel is held, pay $3.50”)
  • Your bank (“unusual activity detected, click to verify”)
  • The ATO (“you have a refund, click to claim”)
  • Toll road providers (“outstanding toll payment”)
⛔ Important
Never tap links in SMS messages about deliveries, tax refunds, or banking. Go directly to the official website or app instead. Australian banks will never ask you to verify your account by following an SMS link.

If Your Device Is Lost or Stolen

  1. Immediately use Find My (iOS) or Find My Device (Android) to locate and, if necessary, remotely wipe it
  2. Change passwords for your email and any accounts accessible from the device
  3. Contact your bank if banking apps were on the device
  4. Report to IT if the device had work data or MDM (Mobile Device Management) enrollment
  5. File a police report if stolen, required for insurance claims
✓ Key Point
Enable Find My on iOS or Find My Device on Android before you need it. Remote wipe works only if you have a Google or Apple account linked and the device has internet access. Configure it today.
