The OCTAVE Risk Assessment Methodologies

Published: 22 April 2010

ID: G00203984

Analyst(s): Ramon Krikken


The Operationally Critical Threat, Asset, and Vulnerability Evaluation (OCTAVE) family of risk assessment methods was designed by the Networked Systems Survivability (NSS) program at Carnegie Mellon University's Software Engineering Institute (CMU/SEI). The original OCTAVE method and related documents were published in 2001, and a streamlined version called the OCTAVE Allegro method was published in 2007. Both are geared for the enterprise and provide a structured, but customizable, asset-driven analysis and mitigation planning approach that aims to be comprehensive in information risk scope and depth. In this assessment, Analyst Ramon Krikken examines the strengths and weaknesses of these risk assessment methods.
