Evidence collection and forensics procedure
How evidence of an incident is identified, collected, preserved and handed over so that it can be relied on later.
How the register reads it
| Also called | evidence handling, chain of custody |
|---|---|
| Family | Resilience and incidents |
| Document type | Procedure. The regimes ask for the content, not the label; a line pasted as a standard, procedure, plan or schedule is placed here with the label noted. |
| Folds into | The regimes accept it folded into the incident response plan; when neither is listed, the gap is counted once, under the parent. |
| Expected owner | The information security lead (CISO or ISMS manager). |
| Review cadence | Annual (the register's default: the clauses say planned intervals and on significant change, and do not fix a period). |
| On the gap list when | never on its own: the register recognises it and names the clauses, but no ticked regime lists it as a separate document (its parent, incident response plan, is). |
| Template | Digital forensics policy. |
