Use internet connections you trust, such as your home service or Long-Term Evolution connection through your wireless carrier. Public networks are not very secure, which makes it easy for others to intercept your data. If you choose to connect to open networks, consider using antivirus and firewall software on your device or using a Virtual Private Network service, which allows you to connect to the internet securely by keeping your exchanges private. When setting up your home wireless network, use Wi-Fi Protected Accessed 3 (WPA3) encryption. All other wireless encryption methods are outdated and more vulnerable to exploitation.
