Evidence Index

Purpose

This page provides the canonical index of all security evidence collected within the Scheol Security Lab.

It ensures that evidence is:

  • uniquely identified
  • linked to risks, controls and validation scenarios
  • traceable over time
  • accessible for review and audit purposes

Evidence represents practical proof that controls are implemented and functioning.

Evidence Status Model

Each evidence item is assigned one of the following statuses:

StatusDescription
PlannedEvidence identified but not yet collected
CollectedEvidence captured and documented
ValidatedEvidence reviewed and confirms control effectiveness
OutdatedEvidence no longer reflects current state

Evidence Types

Evidence is categorized to reflect its nature:

  • Configuration → system or security configuration
  • Operational → logs and runtime behavior
  • Validation → results from verification scenarios
  • Recovery → resilience and restoration proof

Collection Principles

Evidence must be:

  • relevant → directly linked to a control or risk
  • minimal → avoid unnecessary duplication
  • understandable → readable without deep technical context
  • verifiable → reproducible if needed

Traceability Rules

Each evidence must be linked to:

  • at least one control (C-XXX)
  • at least one risk (R-XXX)

Optional but recommended:

  • a verification scenario (V-XXX)

Relationship with Other Sections

Evidence is the final layer of the security model:

  • Risk Register → defines what must be protected
  • Control Framework → defines how it is protected
  • Validation & Monitoring → tests effectiveness
  • Audit & Evidence → proves effectiveness

Governance Rule

No critical control should exist without at least one associated evidence.


Current Scope

At the current stage:

  • evidence coverage is limited and focused
  • only high-value controls are targeted
  • evidence is manually collected

This ensures:

  • consistency with lab maturity
  • avoidance of unnecessary complexity
  • focus on meaningful validation

Current Maturity

Evidence management is considered early but structured.

Established

  • evidence identification model
  • initial linkage with controls and risks
  • defined structure and index

In Progress

  • collection of first real evidence items
  • linkage with verification scenarios
  • improvement of traceability

Planned / Next Phase

  • systematic evidence collection per control
  • centralized evidence storage
  • improved audit-readiness
  • partial automation of evidence generation

This index will evolve as validation activities increase and controls mature.
