As students head back to school, laptops, tablets, and smartphones resume their central role in learning. These devices open doors to research, collaboration, and creativity, but they can also be a gateway for cyber threats if left unprotected.
Whether your student is in elementary school or attending college, taking steps now to secure personal devices can help prevent data breaches, malware infections, and even identity theft during the school year.
Why Device Security Matters in School
Schools have become a prime target for cybercriminals. Shared networks, multiple users, and a mix of personal and school-issued devices make classrooms vulnerable to attacks. An unpatched laptop or a smartphone with outdated security software can quickly become the weak link in the chain, putting personal information, school accounts, and even the broader network at risk.
Best Practices for Securing Laptops, Tablets, and Smartphones
- Use Strong Passwords (and a Password Manager)
- Set unique, complex passwords for school accounts, devices, and apps.
- Consider using a password manager to store credentials securely and avoid reusing passwords.
- Add an extra layer of protection for email, learning portals, and cloud storage.
- Many services offer simple app-based authentication or text codes.
- Install Antivirus and Anti-Malware Software
- Even on Mac or iOS devices, security software can help block malicious downloads and phishing attempts.
- Keep the software updated so it recognizes the latest threats.
- Lock Devices When Not in Use
- Use PINs, fingerprint scanning, or facial recognition.
- Enable auto-lock features to protect data if the device is lost or left unattended.
- Use a Secure Wi-Fi Connection
- Avoid logging into sensitive accounts on public or unsecured school Wi-Fi without a VPN.
- At home, change the default router password and use WPA3 or WPA2 encryption.
Updating and Patching Devices Before School Starts
Just like students need supplies like new notebooks and sharpened pencils, devices need fresh updates to be ready for the school year. Updates and patches fix security holes that hackers could exploit, so starting the year with fully updated devices is critical.
- Run System Updates
- On Windows: Go to Settings > Windows Update and install pending updates.
- On macOS: Open System Settings > General > Software Update.
- On mobile devices: Check the software update settings in iOS or Android.
- Update Apps and Browsers
- Outdated apps and browsers can be exploited. Update them from official app stores before the first day of school.
- Remove Old, Unused Apps
- Unnecessary apps not only take up space, but they may also have security vulnerabilities.
- Enable Automatic Updates
- Turn on auto-update features for operating systems, security software, and apps to stay protected throughout the year.
Following Organizational Procedures
It is also important to be aware of and adhere to your organization’s Bring Your Own Device (BYOD) policies if you are using a personal device to access school or university data/systems. These policies balance the convenience of personal devices with the need to protect institutional data, and will outline required security practices, acceptable use guidelines, and sanctions for non-compliance.

Final Thoughts
Securing laptops, tablets, and smartphones isn’t just about preventing hackers. It’s about protecting your personal information, schoolwork, and even your identity. By starting the school year with secure, fully updated devices, students can focus on what matters most: learning.
Cybersecurity is a habit, not a one-time checklist. Make device updates and security checks part of your back-to-school routine, and you’ll be building good digital habits that last long beyond the classroom.
