Stakeholders ​

Stakeholders (PP) are the external entities interacting with the system under study: suppliers, service providers, partners, customers, regulators. They are used in Workshop 3 of EBIOS RM to build strategic scenarios.


Role in EBIOS RM ​

A risk source can exploit a stakeholder with insufficient trust to reach your business values without a direct attack. This is the principle behind supply-chain attacks.

Example: a cybercriminal compromises a maintenance provider that has remote access to your industrial systems.


Create a stakeholder ​

  1. In Workshop 3, Stakeholders tab, click + Add
  2. Fill in the fields below

Fields ​

FieldDescription
NameLabel of the entity (e.g. ERP vendor, IT outsourcing provider, Cloud host)
TypeSupplier / Service provider / Partner / Customer / Regulator / Subcontractor
DescriptionRole in the ecosystem, services provided, nature of access
DependencyHow much the organisation depends on this entity (1 = low → 4 = critical)
Trust levelEstimated cybersecurity maturity of the entity (1 = low → 4 = high)
Access typePhysical access / Remote logical / Local logical / Shared data / No direct access
Access scopeSystems or data the stakeholder has access to

Assess the criticality of a stakeholder ​

The tool automatically computes a criticality index from the dependency and trust level:

CombinationInterpretation
High dependency + Low trustHigh risk — address as a priority in strategic scenarios
High dependency + High trustModerate risk — monitor how maturity evolves
Low dependency + Low trustLimited risk — include if access is sensitive
Low dependency + High trustLow risk — include for completeness

TIP

A stakeholder with direct access to critical supporting assets always deserves an analysis, even if its dependency is low.


When building strategic scenarios, select the stakeholder as an attack vector: the risk source uses it as an entry point to reach the targeted business value. The likelihood of the strategic scenario incorporates the stakeholder's trust level.


Stakeholder library ​

Import generic stakeholders from the library (common cloud hosts, typical IT integrators, maintenance providers…) or save your recurring stakeholders (regular subcontractors, group suppliers) to reuse them in your future projects.
