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
- Connect log sources and record centrally in {{TECH_SIEM}} (BL-OPS-04).
- Ensure tamper protection & retention {{LOG_RETENTION}}.
- Evaluation & alerting: maintain rules, check anomalies.
- Hand over suspected cases to incident response (VA-01).
- Regular review of coverage and rules.
