Poor internal security procedures and insufficient employee authentication systems are leaving UK businesses prone to internal fraud and intellectual property theft, according to a computer crime survey. Employees at one in five large UK organisations can gain unauthorised access to sensitive information because of insufficient identity and access management processes, says the Department of Trade and Industry’s (DTI’s) biennial security report. Separate research published this week by BDO Stoy Hayward says employee fraud rose 80 per cent last year, costing firms £67m.
