More than half of IT security decision-makers surveyed by Enterprise Strategy Group said it's harder to defend systems from security lapses by insiders than it was in 2011. "One of the big revelations in the survey is that 73% of respondents said they don't block privileged users from access to sensitive data," said Allan Kessler, CEO of Vormetric, which commissioned the study. "... The fundamental problem is that the folks that have access to manage an internal system have incredible amounts of privileges. ... Very few organizations realize that they can keep privileged users from seeing data and still allow them to do their job."
