Module 7. Securing Mobile Devices

 

 SECURING MOBILE DEVICES




DEFINITION

Mobile security refers to securing data on mobile devices such as smartphones and tablets.

IMEI
The International Mobile Equipment Identity (IMEI) number is used to identify a device that uses cellular networks.

RISKS

Mobile device security risks include eavesdropping, unmanaged applications, theft and loss, mobile devices not limiting Internet connections, and unauthorized access.

MALWARE

  • Mobile malware is malicious software that is specifically built to target mobile phones and smartphones systems.
  • Mobile malware steals confidential data, racks up long-distance phone charges, and collects user data.

VULNERABILITIES
  • Mobile application vulnerabilities include insecure data storage, broken cryptography, insufficient transport layer protection, and poor authorization and authentication.
  • Threats to Bluetooth devices include Bluesnarfing, man-in-the-middle attack, and backdoor hacking.

SOLUTION & PREVENTION

  • Regularly updating mobile OS fixes security vulnerabilities and improves app performance.
  • Encrypting smartphones enhances security; Android and iOS use passcodes to encrypt data.
  • To prevent theft: stay alert, encrypt the phone, back up data, and get insurance.
  • If a phone is stolen: contact the service provider, file a police report, and use a tracking app.
  • A SIM PIN adds extra security by protecting the SIM card from unauthorized use.
  • Setting up passcodes protects user data by requiring the correct password to unlock the phone.
  • Auto-Lock saves battery and enhances device security.
  • Data backups help restore lost or accidentally deleted data.
  • Mobile security tools include Lookout Mobile Endpoint Security and Norton Mobile Security.
