Many UK companies are running wireless networks and allowing remote access to their IT systems without having implemented the necessary security.

Research published on Tuesday found that over half of companies with wireless networks say they are not running any additional security, despite experts repeatedly warning that wireless access points are particularly vulnerable to a hacking attack.

The study, part of the Department of Trade and Industry's (DTI) 2004 Information Security Breaches Survey, found that 8 percent of companies know they have experienced a hacking attack on their network. Twenty-three percent said they didn't know whether they had been attacked.
