Instructions

How to use this workbook

StepWhat to do
1Check at least once a year, after every Severity 1 incident and after a change of people, suppliers or systems that the plan relies on (IM-12). Do it with the Incident Response Plan and the contact list open.
2For each item, look at the evidence, not at what people say: open the contact list, test the out-of-hours number, sign in with the emergency account. Record where the evidence is in 'Evidence reference'.
3Enter the owner (the person who keeps the item true), the date you checked, and the result from the list: Pass, Fail, or N/A. A Fail or N/A needs a reason. The Check column prompts for anything missing.
4Items marked Critical are the ones without which the first hours of a serious incident would fail. A Fail on any of them makes the status Not ready: fix it first. Put every Fail on an action list with an owner and a due date — the Incident Case & Action Log's Actions sheet, or your own tracker.
5Read the Summary: counts by area and overall, and the readiness status. Then complete the sign-off: the person who checked, the Head of Information Security, and the executive incident lead who accepts the result.
6Add items of your own on the blank rows at the foot of the checklist, with an ID in the same form (RC-area-number) and an area from the list.
7To clear the EXAMPLE, delete the contents of the 'Row' column and of every yellow column; the items stay.

Legend

Yellow cells are inputs. Everything else is calculated or fixed — do not overwrite formulas.

EXAMPLERows 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 self-check as at 2026-09-30, the quarter of its ransomware incident (INC-2026-014). The plan was exercised on 2026-03-18. One item fails: the ransomware playbook still lacks the site isolation steps the review asked for (PIA-04, overdue). DORA's item is N/A.

Tailoring — small organisation: keep every Critical item; the others can be met simply (one contact list, one playbook for everything but ransomware and payment fraud). N/A is a reason, not a way to skip: say why in the reason column.

Tailoring — regulated financial entity: DORA replaces NIS2's reporting for financial entities. Answer RC-REP-03 instead of RC-REP-01, add items for the classification criteria of Delegated Regulation (EU) 2024/1772 and for reporting major incidents to the management body (DORA Article 17(3)), and test RD-10 to RD-13 in your exercise.

Tailoring — IT run by a managed service provider: most technical items (tooling access, logs, backups, monitoring) are met by the provider. Ask it for the evidence — a restore test report, its log retention, its out-of-hours escalation to your incident manager — and record it here; its word alone is not a Pass.

TermMeaning in this workbook
ReadinessBeing able to respond well to an incident before it happens: the plan, people, contacts, access, evidence, backups, reporting routes and suppliers in place and tested.
PassThe evidence shows the item meets its 'Pass when' criterion today.
FailThe evidence shows it does not, or there is no evidence. Give the reason and put it on the action list.
N/AThe item does not apply to you, for example DORA for an organisation that is not a financial entity. Give the reason.
Critical itemOne without which the first hours of a serious incident would fail. A Fail on any makes the status Not ready.
Rule testedThe rule of the Security Incident Management Policy the item checks (IM-01 to IM-12).
ExerciseA planned rehearsal of the plan: a discussion of a scenario, a test of a part (a restore, a call tree), or a full simulation. A live incident is not an exercise.
RetainerAn agreement with an incident response firm, or the insurer's panel, to help at short notice on agreed terms.
Decision rightsWho may take the decisions with business impact in an incident, as the Incident Response Plan sets them.
NIS2Directive (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.
GDPRThe General Data Protection Regulation, Regulation (EU) 2016/679. Applies whenever personal data is affected.
DORAThe 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.
CSIRTComputer security incident response team: the national team (or the competent authority) that receives NIS2 reports.
EXAMPLEA worked example: a wholesale distributor with about 900 staff, three warehouses and an online ordering service that takes 60% of its orders, as at 2026-09-30. Clear the EXAMPLE answers before use.
