EBIOS — Lesson 2: Risk Sources, Targeted Objectives, Ecosystem Dependencies, and Strategic Scenarios

Learning Objectives

• Map the roles, prerequisites, decisions, and evidence shaping risk Sources, Targeted Objectives, Ecosystem Dependencies, and Strategic Scenarios for a digital service owner analyzing strategic and operational cyber-risk scenarios with business, technical, and supplier stakeholders.
• Build strategic scenario and ecosystem map through a controlled activity with reviewable checkpoints.
• Resolve an ecosystem dependency is omitted from a strategic scenario, validate the correction, and record the accepted result.

Detailed Topics

• Risk Sources
• Targeted Objectives
• Ecosystem Dependencies
• Strategic Scenarios
• Decision ownership, prerequisites, and acceptance evidence for risk Sources, Targeted Objectives, Ecosystem Dependencies, and Strategic Scenarios
• Security, compliance, resilience, documentation, and support implications for EBIOS workshop analysis

Instructor Demonstration

The instructor demonstrates risk Sources, Targeted Objectives, Ecosystem Dependencies, and Strategic Scenarios within a digital service owner analyzing strategic and operational cyber-risk scenarios with business, technical, and supplier stakeholders, records each material decision in strategic scenario and ecosystem map, and contrasts the accepted state with the controlled exception where an ecosystem dependency is omitted from a strategic scenario.

Hands-On Exercise

Complete a controlled exercise focused on risk Sources, Targeted Objectives, Ecosystem Dependencies, and Strategic Scenarios. Establish the expected outcome, produce strategic scenario and ecosystem map, introduce the case where an ecosystem dependency is omitted from a strategic scenario, apply a reversible correction, and rerun the original acceptance checks.

1. Confirm the requirement, stakeholders, environment, assumptions, inputs, and expected result.
2. Perform the EBIOS workshop analysis workflow and capture evidence before and after each material decision.
3. Test normal, boundary, failure, security, compliance, recovery, and operational conditions where relevant.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Identify the business or assurance decision required within a digital service owner analyzing strategic and operational cyber-risk scenarios with business, technical, and supplier stakeholders.
• Compare control strength, evidence quality, operational impact, cost, resilience, and stakeholder trade-offs.
• Define escalation, communication, recovery, acceptance, and follow-up requirements for strategic scenario and ecosystem map.

Troubleshooting Guidance

When an ecosystem dependency is omitted from a strategic scenario, separate the visible symptom from its governing requirement, verify source evidence and recent changes, test one reversible hypothesis, and update strategic scenario and ecosystem map only after the corrected state passes normal and boundary checks.

Validation Checklist

• strategic scenario and ecosystem map identifies the approved baseline, accountable owner, inputs, and expected result.
• Evidence confirms risk Sources, Targeted Objectives, Ecosystem Dependencies, and Strategic Scenarios under normal and relevant exception conditions.
• The response to “an ecosystem dependency is omitted from a strategic scenario” is reversible, tested, and supported by before-and-after records.
• Residual EBIOS workshop analysis risk, support ownership, deadlines, and the next action are recorded.

Lesson Outcome

Learners can apply Risk Sources, Targeted Objectives, Ecosystem Dependencies, and Strategic Scenarios, explain the choices made, and defend the result using strategic scenario and ecosystem map.
