When using public WiFi it is necessary to be cautious. Why?
Any free Wi-Fi should be considered unsecure.
If you go online through an unsecured network, be aware that individuals with malicious intent may have established a Wi-Fi network with the intent to gain access to your systems.
This could allow the hacker to steal your user name and passwords, financial information, or other sensitive and personal information.
It’s also possible the hacker could infect your system with malware.
Avoid typing any sensitive information when using public or unsecured WiFi connection.
Conduct your financial transactions from a secured home connection. Passwords, credit card numbers, or other financial information are vulnerable on a public network.
When doing banking or on-line shopping avoid public WiFi networks and make sure the site you are using is security enabled.
Look for web addresses with “https://” or “shttp://” which mean the site has taken additional steps to help secure your information.
“http://” is not secure.
If you must enter credit card numbers while using a public network, make sure you see a locked padlock icon in the corner of the browser window, and make sure the web address begins with https: (the "s" stands for secure).
When in a public space it is safer to connect to the web through your wireless carrier and use your 3G or 4G connection.
