Are Public Wi-Fi Networks Safe?

The question is while these public networks can be tempting to use especially when they are free, unless it is a matter of life and death, you must never log in to them. In fact the threat level of these public networks is so severe that all modern PC operating Systems and even mobile OS have an automated warning that is displayed whenever you attempt to sign into a public network.

Because public networks are unsecured, hackers and cybercriminals have been known to hack into public networks with hacking software such that the personal information of anyone that connects to that network goes straight to the hacker, which makes it easy for the hacker to steal the user’s identity. Some hackers even create their own public networks for unsuspecting users, making the aforementioned users more vulnerable to social engineering scams.

Use strong passwords

Strong passwords that are not easily deciphered will give you an added layer of protection because it will make the hacker unable to access your accounts. It is also practical for you not to use the same password for all your accounts. Thus if the criminal breaches any of your accounts, all of your accounts are not vulnerable.

You should limit how much personal information you share on a public network. Identity information, such as social security numbers, account details, health records and crucial company data should not be shared on an untrusted network.
