The Operationally Critical Threat, Asset, and Vulnerability Evaluation (OCTAVE) is a framework for identifying and managing information security risks. It defines a comprehensive evaluation method that allows an organization to identify the information assets that are important to the mission of the organization, the threats to those assets, and the vulnerabilities that may expose those assets to the threats. By putting together the information assets, threats, and vulnerabilities, the organization can begin to understand what information is at risk. With this understanding, the organization can design and implement a protection strategy to reduce the overall risk exposure of its information assets.[1]
OCTAVE was developed in 2001 at Carnegie Mellon University (CMU), for the United States Department of Defense. The framework has gone through several evolutionary phases since that time, but the basic principles and goals have remained the same. Two versions exist: OCTAVE-S, a simplified methodology for smaller organizations that have flat hierarchical structures, and OCTAVE Allegro, a more comprehensive version for large organizations or those with multilevel structures.[2]
How it Works[3]
OCTAVE is a flexible and self-directed risk assessment methodology. A small team of people from the operational (or business) units and the IT department work together to address the security needs of the organization. The team draws on the knowledge of many employees to define the current state of security, identify risks to critical assets, and set a security strategy. It can be tailored for most organizations.
Unlike most other risk assessment methods the OCTAVE approach is driven by operational risk and security practices and not technology. It is designed to allow an organization to:
Direct and manage information security risk assessments for themselves Make the best decisions based on their unique risks Focus on protecting key information assets Effectively communicate key security information
