<!-- FULFILLS 5.2.5-M1, 5.2.5-S1, 5.2.6-M1, A.8.8-1 | POLICY R10 -->

## 1. Purpose

This procedure governs the detection, assessment, treatment and technical review of vulnerabilities. It operationalises the associated policy ({{LINK:R10}}).

## 2. Scope

Applies within the ISMS scope ({{ISMS_SCOPE_DESCRIPTION}}).

## 3. Trigger

Regular scan ({{VULN_SCAN_FREQ}}), security advisory/CVE, penetration test ({{PENTEST_FREQ}}).

## 4. Inputs

- Scan/test reports
- Asset inventory & criticality
- Patch SLA (BL-OPS-01)

## 5. Process

1. Identification: evaluate vulnerability scan {{VULN_SCAN_FREQ}} (BL-OPS-02) and advisories.
2. Assessment & prioritisation according to criticality and exposure.
3. Initiate treatment: patch/change (VA-04) or compensating measure.
4. Technical review: hardening (BL-OPS-07) and penetration tests ({{PENTEST_FREQ}}, BL-OPS-08).
5. Tracking & verification of the remediation in {{TOOL_TICKET}}.

## 6. RACI

| 1 | Identification | {{ROLE_IT_LEAD}} | {{ROLE_IT_LEAD}} | - | - |
| 2 | Assessment & prioritisation by criticality | {{ROLE_IT_LEAD}} | {{ROLE_ISB}} | - | - |
| 3 | Initiate treatment | {{ROLE_IT_LEAD}} | {{ROLE_IT_LEAD}} | {{ROLE_ISB}} | - |
| 4 | Technical review | {{ROLE_IT_LEAD}} | {{ROLE_ISB}} | External service provider | - |
| 5 | Tracking & verification of the remediation | {{ROLE_IT_LEAD}} | {{ROLE_ISB}} | - | - |

## 7. Result & evidence

Tracked vulnerabilities with treatment status in {{TOOL_TICKET}}; test reports. Evidence is referenced in the central evidence register ({{LINK:NACHWEISREGISTER}}).

## 8. Key performance indicators (KPI)

- Mean time to remediate per criticality
- Open critical vulnerabilities
- Scan coverage
