Instructions
How to use this workbook
| Step | What to do |
|---|---|
| 1 | Set the As-at date on the Summary sheet. The EXAMPLE uses 2026-09-30, the example quarter end; use today's date, or type =TODAY(). Set your working hours and the date the plan was last exercised there too. |
| 2 | Open a row on the Cases sheet for every declared incident (IM-03): a case number that never changes, the title, the category and the severity at declaration from the Incident Classification, Severity & Escalation Matrix (keep it; the Severity column holds the current one, and any change is recorded with its time and reason, IM-04), the reporter, and the times it was detected, reported and triage started. Whether triage was on time calculates: 30 minutes in working hours and 60 outside them (IM-02). Record events closed at triage in your service desk; this log holds incidents. |
| 3 | Record the declaration time: it is the time of awareness, when every reporting clock starts. Within 4 hours, record the outcome of the reporting screen for NIS2, GDPR and DORA, with the reasons, whether or not a report is made (IM-06), and say whether it was reported as a NIS2 significant or DORA major incident. |
| 4 | Add each report on the Reports sheet with its duty ID from the Incident Classification, Severity & Escalation Matrix. The deadline calculates from the declaration time, or from the earlier report its clock runs from; enter the time each report is made, and the result shows On time or Late. Add contract, insurer and police notices too: they have no legal clock and are not counted in IMM-02. |
| 5 | Keep the timeline on the Timeline sheet as the incident runs: what happened or was decided, when, who, and where the evidence is (IM-07). Decisions to isolate, stop a service or report go here with who took them (IM-08). |
| 6 | Record containment, restoration and closure. Close a Severity 1 or 2 incident only after the 7-day monitoring period without recurrence. The review is due within 10 working days of closure (IM-11); severity 3 and 4 incidents are reviewed together once a quarter. Enter the review date and each review action on the Actions sheet with an owner and a due date. |
| 7 | Link each case to the risks it touches in the P05 Information Security Risk Register (they must be reassessed) and to the suppliers involved in the P06 Supplier Security Risk Register. |
| 8 | Take the Summary figures to executive management every quarter (IM-12). Delete the EXAMPLE rows on every sheet before the log is approved. Do not type over the white calculated columns. |

Yellow cells are inputs. Everything else is calculated or fixed — do not overwrite formulas.
| EXAMPLE | Rows marked EXAMPLE in the first column show how a completed row looks. Delete them before approval. |
EXAMPLE: a wholesale distributor with about 900 staff, three warehouses and an online ordering service that takes 60% of its orders, an important entity under NIS2 in its Member State; not a financial entity, so DORA's reporting duties do not apply. Its five incidents of Q3 2026, as at 2026-09-30: the ransomware incident at Warehouse 2 (INC-2026-014), reported to the authority as significant and contained 6 hours after detection; a request to change a supplier's bank details, stopped by the call-back check; an order spreadsheet sent to the wrong customer and notified under GDPR; a staff mailbox taken over, declared Severity 2 and lowered to 3 once the audit log showed no personal data had gone; and blocked attempts on the ordering platform, still open. One review action (PIA-04) is overdue.
Working hours are 08:00 to 18:00, Monday to Friday, in the EXAMPLE; change them on the Summary sheet. Review due dates count Monday to Friday and do not know your public holidays: add them to the WORKDAY formula if you need them.
Tailoring — small organisation: the Cases and Actions sheets are the minimum. If you have few incidents, keep the timeline in the case's notes and use the Reports sheet only when a report is made; keep the review for Severity 1 and 2.
Tailoring — regulated financial entity: DORA replaces NIS2's reporting for financial entities. Answer the DORA screen, record when the incident was classified as major on the Reports row for RD-10, and log RD-10 to RD-13 instead of RD-01 to RD-05. DORA Article 17(2) expects every ICT-related incident and significant cyber threat recorded, with its root cause: keep this log for all of them, not only the major ones.
Tailoring — IT run by a managed service provider: the provider's tickets are evidence, not the case log. Copy its detection, triage and containment times into the case row, name its ticket in the timeline's evidence column, and keep the log yourself: the reporting duties and the review are yours.
Cases
One row per declared incident (IM-03). Yellow columns are inputs; white columns calculate. Times are local, as the case log records them.

Definitions
Definitions
| Term | Meaning in this workbook |
|---|---|
| Event | Something observed or reported that might affect the security of our information or services. Most events are not incidents. |
| Incident | An event, declared by the incident manager, that has compromised, or threatens to compromise, the availability, authenticity, integrity or confidentiality of our data or services, and needs a managed response. |
| Near miss | An event that could have compromised our data or services but was prevented or did not happen, and needs nothing beyond logging. Logged, never declared. An attack that was stopped but still needs response work, such as warning a supplier, confirming a patch or watching for a repeat, is declared, usually at Severity 4. |
| Significant incident (NIS2) | NIS2's term: an incident that has caused or could cause severe operational disruption or financial loss to us, or considerable damage to others. Reported to the authority on NIS2's clock. |
| Major ICT-related incident (DORA) | DORA's term, for financial entities only: an ICT-related incident with a high adverse impact on systems that support critical or important functions, as tested by Delegated Regulation (EU) 2024/1772. |
| Personal data breach (GDPR) | GDPR's term: a breach of security leading to the accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to, personal data. |
| Awareness | The moment the reporting clocks start: the time the incident is declared, as recorded in the case log, unless the record shows we had reasonable certainty earlier, in which case the earlier time. |
| Containment | The incident can no longer spread or cause new harm, even though systems may not yet be restored. |
| Closure | Recovery criteria met, the monitoring period passed without recurrence, and the case log complete. |
| Case ID | The incident's number, given at declaration and never changed (IM-03). The EXAMPLE uses INC-year-number. |
| Severity at declaration | The severity set when the incident was declared. The Severity column holds the current one; a change, and its time and reason, is recorded beside it (IM-04). |
| Detected | When the first sign was seen, by a person or a tool. IMM-01 measures from here to containment. |
| Reported in working hours | Reported between the working hours set on the Summary sheet, Monday to Friday. Sets the triage limit (IM-02): Triage of every reported event must start within 30 minutes of the report in working hours and 60 minutes outside them, and must end within [[30]] minutes of starting with the event closed with a recorded reason or declared an incident. |
| Screen outcome | Every incident must be screened against every reporting duty (NIS2, GDPR, DORA where it applies, contracts and insurance) within 4 hours of declaration, and the decision and its reasons recorded whether or not a report is made. |
| Review due | 10 working days (Monday to Friday) after closure, for Severity 1 and 2 (IM-11). Severity 3 and 4 incidents are reviewed together once a quarter. |
| Deadline | From the duty's clock in the Incident Classification, Severity & Escalation Matrix: hours after awareness, or after the earlier report the clock runs from; a one-month clock is due by the end of that day a month later. For DORA's initial notification, the earlier of 4 hours after classification as major and 24 hours after awareness. |
| Overdue (action) | An action not done whose due date is before the As-at date (IMM-03). |
| NIS2 | Directive (EU) 2022/2555 on measures for a high common level of cybersecurity across the Union, as transposed in your Member State. Applies to essential and important entities. |
| GDPR | The General Data Protection Regulation, Regulation (EU) 2016/679. Applies whenever personal data is affected. |
| DORA | The Digital Operational Resilience Act, Regulation (EU) 2022/2554, with its Delegated Regulations (EU) 2024/1772 and 2025/301. Applies to financial entities only; for them its reporting replaces NIS2's. |
| CSIRT | Computer security incident response team: the national team (or the competent authority) that receives NIS2 reports. |
| P05, P06 | The Risk Management pack (the Information Security Risk Register) and the Third-Party Security Risk Management pack (the Supplier Security Risk Register) that this log links to. |
| IM-nn, IC-nn, RD-nn, IMM-nn | Rule, category, reporting duty and measure numbers used across the pack; the rules and measures are in the Security Incident Management Policy. |
| EXAMPLE | A worked example: a wholesale distributor with about 900 staff, three warehouses and an online ordering service that takes 60% of its orders, Q3 2026, as at 2026-09-30. Delete the EXAMPLE rows before approval. |
