Insider threats are becoming increasingly worrisome to corporate security executives. That is one of the findings in a survey of C-level businesspeople Nuix released last week. “The insider threat seems to be a bigger concern this year than it was in previous years,” said Nuix’s Keith Lowry. “People are recognizing that it is a significant weakness that has yet to be fully addressed by most organizations.” Insider threat programs are widespread across the broad set of industries represented by 28 high-level execs participating in the study.
