What is Mobile Device Security?

Mobile device security refers to the measures individuals and organizations take to protect their privacy, data,
and mobile device functionality against security threats.

Some Potential Threats

  • Malicious apps, spyware, or ransomware
  • Phishing scams via email, SMS (short service message) messages, or voice calls
  • Unsecure Wi-Fi networks which can lead to Wi-Fi spoofing or man-in-the-middle attacks

Signs Of A Hacked Device

  • Unusual battery drain, overheating, or slow performance could be a sign of malware or running in the background
  • Increased or unexplained data usage can be a sign that data is being transmitted to a remote server
  • Unwanted pop-up ads or strange notifications is due to adware or malicious apps
  • Unfamiliar apps, files, photos, or videos
  • Settings, such as Wi-Fi, Bluetooth, or security features, have been changed without your input

If you suspect your device has been hacked, take immediate action:

  • Change your passwords
  • Ensure you enable multifactor authentication
  • Seek professional help (e.g. device’s manufacturer)
  • Scan for malware using reputable security apps or software
  • Consider factory resetting the device if your unable to remove the threat
  • Delete unfamiliar or suspicious apps
  • Update software and apps (if not up to date)

Securing Mobile Devices

  • Create strong passwords
    • Do not use the same password across multiple devices, emails, or accounts
    • For iPhone users, set a passcode longer than the 4-number preset
  • Leverage biometric authentication such as fingerprint, voice, iris, or facial recognition
  • Set up remote tracking, encryption, and data wiping capabilities in case the device is lost or stolen and securing your data takes priority
  • Avoid using public Wi-Fi or charging stations
  • Download apps from reputable sources (e.g. App Store, Google Play)
  • Enable multifactor authentication (MFA) on mobile accounts or apps
  • Regularly back up your mobile device’s data to a secure location (e.g. cloud storage, external hard drive)
