'A Taxonomy of Operational Cyber Security Risks' by CMU's James J. Cebula and Lisa R. Young is a year-old paper that attempts to classify all the ways that technology go wrong, and the vulnerabilities than ensue. Fascinating reading, a great primer on technology and security, and as a bonus, there's a half-dozen science fiction/technothriller plots lurking on every page.
This report presents a taxonomy of operational cyber security risks that attempts to identify and
organize the sources of operational cyber security risk into four classes: (1) actions of people,
(2) systems and technology failures, (3) failed internal processes, and (4) external events. Each
class is broken down into subclasses, which are described by their elements. This report discusses
the harmonization of the taxonomy with other risk and security activities, particularly those de-
scribed by the Federal Information Security Management Act (FISMA), the National Institute of
Standards and Technology (NIST) Special Publications, and the CERT Operationally Critical
Threat, Asset, and Vulnerability Evaluation (OCTAVE) method.
