Study Notes
OCTAVE Overview
- OCTAVE stands for Operationally Critical Threat, Asset & Vulnerability Evaluation, aimed at identifying and evaluating information security risks.
- Developed by Christopher Alberts at Carnegie Mellon University (CMU).
- Methodology supplies tools, techniques, and methods for risk-based strategic assessment and planning in information security.
Key Features
- Emphasizes strategy over technology; not technology focused.
- Takes into account the organization’s needs and operational context.
- Employs a top-down, qualitative risk assessment approach, specifically targeting threats based on critical assets.
- Process-driven, flexible, customizable, and self-directed led by the organization’s employees.
Comparison with Other Frameworks
- Strategic focus vs. tactical focus.
- Security practices emphasis instead of technology focus.
- Organization-wide evaluation as opposed to system-based evaluation.
- Self-directed processes compared to expert-led frameworks.
- Utilizes a top-down approach instead of a bottom-up approach.
Team Composition
- Involves both operational (business) units and the IT department in the evaluation process.
Functionality
- Identifies critical organizational assets and conducts risk analysis on them.
- Evaluates the relationship between assets, associated threats, and vulnerabilities.
- Develops practice-based protection strategies and risk mitigation plans.
OCTAVE Phases
- Employs a structured three-phase approach analyzing both organizational and technology issues:
-
Phase 1: Build Asset-Based Threat Profiles
- Determine critical assets and current protection measures.
- Identify security requirements for each critical asset.
- Identify vulnerabilities within existing practices.
- Create threat profiles for critical assets.
-
Phase 2: Identify Infrastructure Vulnerabilities
- Identify network access paths and relevant IT components tied to critical assets.
- Evaluate IT components identified in the previous step.
-
Phase 3: Develop Security Strategy and Mitigation Plans
- Conduct risk analysis based on the previous phases.
- Formulate protection strategies and mitigation plans.
-
Phase 1: Build Asset-Based Threat Profiles
Threat Profile Characteristics
- Components of a threat profile include the asset type, access method, actors involved, their motives, and potential outcomes from security requirement violations.
- Example outcomes include unauthorized access, tampering, loss/destruction of assets, and creation of unauthorized objects.
Example of Threat Profile
- For SLIIT student records on the ‘S01’ server:
- Accidental data entry leading to inconsistent records (modify outcome).
- Potential misuse of records for personal gain (risk of deliberate motive).
- Involves both insiders and outsiders as actors, with network access paths noted for exploitation.
