If possible, always use a private network when logging onto the internet. Public wireless networks are openly connected and usually go unencrypted and unsecured. This means that hackers can easily intercept data in order to track your activity and see which websites you’re visiting. If you absolutely have to use public Wi-Fi, make sure to stay away from sensitive online activities, such as making credit card payments or sending emails to co-workers with classified information.
