+## 1. Purpose
+
+This procedure governs the collection, protection, evaluation and retention of security-relevant log data. It operationalises the associated policy ({{LINK:R10}}).
+
+## 2. Scope
+
+Applies within the ISMS scope ({{ISMS_SCOPE_DESCRIPTION}}).
+
+## 3. Trigger
+
+Continuous operations; security-relevant event; alert from {{TECH_SIEM}}.
+
+## 4. Inputs
+
+- Log sources/systems
+- Retention requirements (BL-OPS-04)
+- Alerting rules
+
+## 5. Process
+
+1. Connect log sources and record centrally in {{TECH_SIEM}} (BL-OPS-04).
+2. Ensure tamper protection & retention {{LOG_RETENTION}}.
+3. Evaluation & alerting: maintain rules, check anomalies.
+4. Hand over suspected cases to incident response (VA-01).
+5. Regular review of coverage and rules.
+
+## 6. RACI
