A shocking statistic, but one that possibly comes from a lack of knowledge? Internet security, or lack there of, is a big issue, especially when working over public WiFi. You may as well stand in a crowded area, hold up your bank card and scream out the PIN number at the top of your voice.
I recently wrote an article on the subject, which I would recommend having a read though. A few facts may surprise you:
SecureAuth, a leader in adaptive access control, has released the results of a new survey which reveals that Brits have a risky attitude to internet browsing where they would choose to have speed over security. A concerning 71 percent of participants would choose faster internet speed over improved security; with just 29 percent choosing the opposite. Furthermore, three in five Brits will share personally identifiable information (PII) over public WiFi.
