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.

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.
