2.7: Securing Mobile and Embedded Devices

Screen Locks

Restrict access using facial recognition, PIN, fingerprint, or pattern; devices may lock, erase, or require account login after failed attempts.

Locator Apps & Remote Wipe

GPS-based tools to locate, sound alarm, display message, or wipe device remotely.

Patching & Updates

Mobile devices need regular OS updates and patches for features, bug fixes, and security.

Full Device Encryption

Encrypts all mobile data; iOS uses passcode-based encryption, Android has built-in encryption (5.0+).

Remote Backup

Cloud-based, continuous backups without cables; allows one-click restoration of apps and data.

Mobile Antivirus/Antimalware

iOS is closed and restrictive, Android is more open and vulnerable; apps run in sandbox, 3rd-party protection available.

Mobile Firewalls

Rarely used; most activity is outbound; Android has some firewall apps, enterprises enforce access through policies.

Mobile Device Policies

Managed with MDM; enforce app, data, and camera restrictions; require screen locks and PINs; support BYOD environments.

IoT Security

Includes sensors, smart devices, wearables, automation; often shipped with weak defaults—best practice is network isolation.
