## 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.
