A false positive is
- "[a]n alert that incorrectly indicates that malicious activity is occurring."
- "[a]n instance in which a security tool incorrectly classifies benign content as malicious."
- "the misidentification of an individual as a person on a terrorist watch list when he or she is not, in fact, that person."
"Every false positive also has an opportunity cost; that is, it is associated with a waste of resources — precious investigative or analytical resources that are expended in the investigation of a innocent individual. In addition, false positives put pressure on officials to justify the expenditure of such resources, and such pressures may also lead to abuses against innocent individuals."
