According to some Data Breach Incident Response (DBIR) analyses, insider threat may be the 2nd or 3rd major reason for data loss. It’s interesting to note that the insider threat is way down in the actual number of incidents, but they count for a larger number of successful data loss incidents because the insider knows where the data is, may have legitimate access to the data, and may know the controls that need to be bypassed to exfiltrate it.
