This document defines a National Cybersecurity Center of Excellence (NCCoE) project to provide guidance and a reference architecture that will assist an organization in detecting, responding to, and recovering from a loss of data confidentiality. Data confidentiality refers to protection of data from unauthorized access and disclosure, including means for protecting personal privacy and proprietary information. Confidentiality is relevant for data at rest, in use, and in transit.
Lapses in data confidentiality can lead to a data breach.
A breach may include internal and external unauthorized access or disclosure.
