Risk Assessment and Treatment Process¶
Purpose. Defines how Soon identifies, analyses, evaluates and treats information security risks (ISO/IEC 27001:2022 6.1.2, 6.1.3, 8.2, 8.3). It is the methodology; its output is the Risk Assessment Report (ISMS-DOC-06-3) and the Risk Treatment Plan (ISMS-DOC-06-4), which together justify the Statement of Applicability.
1. Scope & inputs¶
Risk assessment covers all assets in the Information Asset Inventory within the ISMS scope. Inputs: the asset inventory, the context/issues (SWOT/PESTLE), interested-party requirements, legal/regulatory obligations (GDPR, NIS2), threat intelligence, and incident history.
2. Approach¶
Soon uses a combined asset-based and scenario-based method, kept deliberately lean for a small team:
- Identify risks — for each asset (or asset group) and key threat scenario, identify how Confidentiality, Integrity or Availability could be compromised (threat × vulnerability).
- Assign a risk owner — the person accountable for the risk decision.
- Analyse — rate Likelihood and Impact (scales below); Risk = L × I.
- Evaluate — compare the score to the acceptance criteria and risk appetite.
- Treat — choose a treatment option; identify the Annex A controls; record the target residual risk.
- Record — in the Risk Assessment Report; track actions in the Risk Treatment Plan.
3. Likelihood scale¶
| Score | Level | Meaning |
|---|---|---|
| 1 | Rare | Not expected to occur (≈ once in 5+ years) |
| 2 | Unlikely | Could occur occasionally (≈ once in 2–5 years) |
| 3 | Possible | Might well occur (≈ yearly) |
| 4 | Likely | Expected to occur (≈ several times a year) |
| 5 | Almost certain | Expected frequently / already occurring |
4. Impact scale¶
| Score | Level | Indicative impact (any one dimension qualifies) |
|---|---|---|
| 1 | Insignificant | Negligible effect; no data/PII exposure; no customer impact |
| 2 | Minor | Minor disruption; internal only; easily recovered |
| 3 | Moderate | Limited PII/customer-data exposure; short outage; minor SLA/contract impact |
| 4 | Major | Significant PII breach; notable outage; GDPR notification; contractual penalties; reputational harm |
| 5 | Severe | Large-scale data breach; prolonged outage; major regulatory fines; serious reputational/financial damage |
5. Risk rating & acceptance criteria¶
Risk = Likelihood × Impact (1–25).
| Score | Level | Action (Moderate risk appetite) |
|---|---|---|
| 1–4 | 🟢 Low | Acceptable — retain; no treatment required (monitor) |
| 5–9 | 🟡 Medium | Treat where proportionate; risk owner decides; document the decision |
| 10–25 | 🔴 High | Must be treated — not acceptable to retain, especially where customer data, GDPR compliance or availability is affected |
This reflects Soon's Moderate risk appetite (per the Context & Scope): pragmatic acceptance of low risk, active treatment of anything threatening customer data, compliance, continuity or reputation.
6. Risk treatment options¶
| Option | When used |
|---|---|
| Modify (reduce) | Apply/strengthen Annex A controls to lower likelihood or impact (the default) |
| Retain (accept) | Risk is within appetite; documented acceptance by the risk owner |
| Avoid | Stop the activity causing the risk |
| Share (transfer) | Insurance, or contractual transfer to a supplier (e.g. PCI scope to Stripe) — noting accountability remains with Soon |
After treatment, the residual risk is re-rated. Residual risk above appetite requires explicit risk-owner acceptance and sign-off at management review.
7. Roles¶
- Risk owners — accountable for individual risk decisions and treatment delivery.
- Information Security Manager (Olaf) — maintains the process, report and treatment plan; consolidates for management review.
- Management review — approves residual risk and the treatment plan periodically.
8. Frequency¶
The full risk assessment is reviewed and updated at least annually, and whenever: a significant change occurs (new product/integration, cloud change, major supplier), a significant incident happens, or the threat landscape shifts materially.
9. Link to the Statement of Applicability¶
The set of Annex A controls selected to treat risks determines which controls are applicable in the SoA. The SoA is updated whenever treatment decisions change applicability.
