While no one can live without water, food, and fresh air, there's another factor that seems equally necessary: internet service. Yes, technology is part of this survival kit; humans (especially teenagers) may require Wi-Fi or personal hotspots to keep their professional and personal lives on track.

Public Wi-Fi is the kind you access at places like schools, coffee shops, libraries, or airports. Since connecting to the public internet does not require authentication, it is an attractive target for cybercriminals.

Hackers could take advantage of the vulnerability of public Wi-Fi in two different ways: by positioning themselves between you and the connection point to intercept sensitive data like emails, credit card information, or work login credentials, or by spreading malicious software to your device.

If you use public Wi-Fi frequently for work or school, there's nothing wrong with it as long as you use strong antivirus software or a VPN on your portable devices. Antivirus can protect your digital activity, detect cyberattacks, and warn you about suspicious URLs. VPNs, on the other hand, add an extra layer of defense to your data.
