Cognitive computing is a deliberate transdisciplinary approach to computing whose goal is to mimic human thought, feeling, and decision-making capacity using self-aware computation. The term "self-aware " as related to consciousness, however, has some features that are poorly understood and this serves to constrain the rapid emergence of purely cognitive technology. Cognitive security draws upon many principles underlying cognitive computing, while extending the traditional notions of cybersecurity to include the perplexing problem of misinformation disinformation. Cognitive security has the potential to reinforce edge device user authentication. It lends itself to various network architectures and It applies to the Internet of Things. At the enterprise scale, however, cognitive security serves best to greatly augment, not replace, human decision-making concerning effective cybersecurity response profiles.
