When connecting through a logon page, view the site’s certificate presented by the browser to verify that the site is operated by the expected organization.In addition, turn off file and printer sharing to make it harder for a stranger to check your wireless activities, and avoid sending any confidential information (Social Security numbers, bankaccount passwords, and so on) over a Wi-Fi connection.
