Public Wi-Fi security refers to the protection measures necessary when using wireless internet in shared spaces like cafes, airports, or hotels. It’s vital to safeguard your data from potential threats. Public networks are often less secure than private ones, making users vulnerable to cyberattacks. To enhance security, avoid sensitive transactions or sharing personal information on these networks. Always connect to reputable networks and use a virtual private network (VPN) for added encryption. Turn off sharing settings, enable a firewall, and keep your device’s software updated. Vigilance and caution are key to preventing unauthorized access and data breaches on public Wi-Fi.
