OPS-13 Logging and Monitoring - Identification of Events
Analyse logging data automatically against the defined event criteria, including correlation of relationships between events, and report identified events automatically to the appropriate departments for prompt evaluation and action.
Source: BSI C5 (121-criteria catalogue), OPS-13. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open BSI C5 (121-criteria catalogue) in the compliance library.
The edition of the catalogue is not stamped here; check the edition your attestation is issued against.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- No correlation configured, so only single event signatures are ever detected
- Alert volume so high that meaningful rules are suppressed wholesale
- Detection content never extended after new services were onboarded
- Events generated with no defined recipient outside business hours
