Too many users fall for cyber security urban myths

Some computer users astonishingly believe that answering their mobile phones will leave them open to computer viruses. And such fundamental misunderstandings over IT security issues are rife among staff in businesses across the globe, according to a new study.

The 'Top Ten Cyber Security Urban Legends' released by Secure Computing Corporation warns that, while such improbable stories circulating on the internet are amusing, they highlight serious problems related to misperceptions among end users about cyber security.

Secure Computing Corporation compiled its list based on support calls, customer requests, and monitoring of internet discussion groups. It found that, while most of these legends are harmless, some can cause real harm if taken seriously.
