IT administrators fear that sensitive data is most likely being stolen using USB drives and e-mail systems. According to a newly published report commissioned by software maker Provilla, corporate IT administrators and other technology pros are worrying about the exposure of sensitive company information now more than ever.The results are unsurprising considering the rash of high-profile data leakage events that have been reported by well known companies — such as retailer TJX Companies — over the last several years (and since, you know, Provilla sells data leakage prevention [DLP] applications).According to the survey of 114 IT pros working at companies with over 500 employees, conducted in December 2006 by Boston-based researchers Simon Management Group, some 78 percent of respondents said they were “very concerned” about data exposure. Among the many different methods that could be employed by individuals seeking to make off with sensitive information, respondents ranked removable USB storage drives, corporate e-mail systems and Web mail sites as the three formats they are most concerned about.Other methods of data loss, including Wi-Fi leaks, printed materials and CD-based storage formats also ranked among respondents top worries.Respondents also admitted that they realize that protecting one avenue of potential data loss often leads to people using other unaddressed methods.
