A recent survey of more than 700 IT decision-makers at mid-market and enterprise organizations found that 46 percent say they're vulnerable to an insider attack in spite of their existing security skills, resources, processes and technologies (h/t Softpedia).

The survey by Vormetric and the Enterprise Strategy Group also found that 54 percent of respondents say it's more difficult today to detect and prevent insider attacks than it was in 2011, and 53 percent say they're increasing security budgets due to insider threats.

"While APTs and advanced malware attacks continue in the headlines, the ESG research indicates that organizations remain vulnerable to numerous insider threat vectors," Enterprise Strategy Group senior principal analyst Jon Oltsik said in a statement [PDF]. "This situation must be addressed as it creates an unacceptable level of IT and business risk."

The survey also found that 48 percent of survey respondents believe third party contractors pose an insider threat, and 58 percent admit feeling vulnerable to such contractors abusing access rights.
