To Err is Human: Human Error is Main Cause of PII Breaches

By Steve Muck - Published, February 7, 2011

Human error is the cause of 80 percent of the DON's PII breaches. Not knowing or not following guidance, or just being careless can result in the unintended disclosure of privacy sensitive information and potentially adversely affect many personnel.

The Social Security number is the most frequently lost, stolen or compromised PII data element. The SSN is involved in almost 70 percent of DON breaches. This sensitive identifier must be closely safeguarded or eliminated from use. SSNs are improperly disclosed by: sending SSNs in an email or in attachments, creating recall rosters with SSNs, or posting names with associated SSNs to web portals or shared drives. In these examples, SSNs were either transmitted without encryption, not properly marked or sent to recipients that did not have a need to know.
