Mobile Device Security

Your phone holds a lot of personal and sensitive information, making it a prime target for cyber threats. From phishing scams to malware and unsecured Wi-Fi risks, mobile security threats are everywhere. This page is to help you understand these risks and take steps to protect your device. Follow these best practices to keep your data safe and stay ahead of potential attacks.

Mobile Security Risks  

  • Phishing Attacks: Mobile devices are vulnerable to phishing via email, text, and malicious apps.  

  • Data Breaches: Lost or stolen devices can lead to unauthorized access to sensitive information.  

  • Malware: Malicious apps can install malware to steal personal data or take control of your device.  

  • Wi-Fi Vulnerabilities: Public Wi-Fi networks can expose your device to malicious attacks.  

  

Best Practices to Secure Your Mobile Device  

Use Strong Authentication

  • Enable multi-factor authentication (MFA) for all critical accounts.  

  • Use biometric security (fingerprint, face recognition) or an equivalent app where possible.   

Keep Your Device Updated  

  • Regularly update your operating system and apps to patch vulnerabilities.   

​​​Secure Your Network Connections  

  • Avoid using public Wi-Fi; use a VPN when available.  

  • Turn off Bluetooth and Near Field Communication, such as Apple Pay and Google Pay, when not in use to reduce exposure to attacks.  

Install Trusted Apps Only  
  • Download apps exclusively from official app stores (Google Play, Apple App Store).
  • Check app permissions before installing such as those asking for access to your location, contacts, and other sensitive information.  
Back up Your Data  
  • Regularly back up important files to secure cloud storage using your native backup features such as iCloud for Apple devices or Google Drive for Android devices.  
Enable Device Tracking and Wipe Features  
  • Activate "Find My Device" for Android/Google devices or “Find My iPhone” on Apple devices to locate lost devices or remotely wipe data if your device is stolen.  
Beware of Phishing Scams  

  • Be cautious of unsolicited emails or texts asking for personal information and avoid clicking on suspicious links or downloading unknown attachments.

Always Use a Lock Screen 

  • Ensure that you lock your mobile device with a passcode that is at least 4-6 digits.  

  • Make it so that no personal information is on your lock screen. 

  • Do not use repeating numbers on your lock screen. 

 

  

Examples of Mobile Threats  

  • A malicious app disguised as a legitimate productivity tool may steal login credentials.  

  • A text message claims your bank account is locked and requests sensitive information.  

  

Reporting Mobile Security Issues   

  1. Use your device’s built-in tools (e.g., “Report Junk” on iOS).  

  2. For district owned devices with security concerns, contact @email.
