The framework has gone through several evolutionary phases since that time, but the basic principles and goals have remained the same. OCTAVE was developed in 2001 at Carnegie Mellon University (CMU), for the United States Department of Defense. Phase 3: Develop Security Strategy and Plans.Phase 2: Identify Infrastructure Vulnerabilities.
Phase 1: Build Asset-Based Threat Profiles. The process goes on to conduct a vulnerability assessment specific to the organization. The first step is to construct profiles of threats based on the relative risk that they pose. OCTAVE is designed to leverage the experience and expertise of people within the organization. The framework defines a methodology to help organizations minimize exposure to likely threats, determine the likely consequences of an attack and deal with attacks that succeed. OCTAVE (Operationally Critical Threat, Asset, and Vulnerability Evaluation) is a security framework for determining risk level and planning defenses against cyber assaults.
