Over a third (35%) of UK workers who use computers say IT security is left up to them when they are outside the workplace, according to research by YouGov.
The online survey of over 2,000 people was commissioned by IT services providerDimension Data.
The company said the research had uncovered a serious gap in the security policies at many companies, particularly as the survey showed more than half of PC users (54%) worked remotely.
The research also showed that just over a quarter of British workers (26%) copied data onto mobile devices for work at least once a week, 32% shared their work computer with other members of their household, and 40% regularly use USB sticks for moving data.
"The research clearly shows that end-user education has a long way to go with 18% of UK workers revealing their work passwords to at least one other person, highlighting an entrenched lack of understanding of the importance of workplace security," said Alastair Broom, line of business director for security at Dimension Data.
