The findings, of a global survey by Internet security firm Check Point Software, indicate that enterprises are struggling to keep up with the escalating mobile and wireless computing trend.

The trend means that a majority of businesses are potentially vulnerable to unauthorised network access from lost or stolen devices.

The Check Point survey was conducted in September 2010, surveying more than 220 IT security administrators located in the Americas, the Asia Pacific, Europe, and the Middle East.

It found that 64 per cent of organisations are concerned that the growth in remote users will result in exposure to sensitive data.
