The plan that fails is the one nobody has read, stored on the file share that just got encrypted.
An incident response plan is judged on one occasion, under time pressure, by people who did not write it. That means it has to be short, findable offline, specific about who decides what, and exercised often enough that the first time is not the real time.

- Findable offlineBecause the file share may be unavailable
- Named decisionsWho declares, who authorises, who speaks
- ExercisedA plan never rehearsed is a document
- CIS Control 17Incident response management, in the eighteen
Seven things that separate a plan from a document.
Named people, named deputies, and current numbers
Roles rather than names ages badly, and names without deputies fail the moment somebody is on a flight. A usable plan lists the person, the deputy, and how to reach both by a route that does not depend on corporate email or the corporate network, because both may be unavailable or untrusted at the moment you need them.
A declaration threshold somebody can apply at 3am
The most consequential decision in any incident is when it becomes one. A plan that says the security team will assess severity and respond appropriately provides no help to the person holding the phone. A threshold that describes observable conditions, and names who can declare, is what converts hesitation into action.
Decision rights, especially the expensive ones
Who can take a production system offline. Who can disconnect a site. Who can authorise engaging external responders, and up to what value. Who can decide not to pay. Those decisions get made under pressure by whoever is present, and a plan that pre-authorises them removes the worst delay in most real incidents.
External contacts, gathered before you need them
Incident response retainer, cyber insurer notification route and policy number, legal counsel, the regulator contact where an obligation exists, key suppliers, and the account team at each critical vendor. Assembling that list is an afternoon of work in peacetime and a very bad hour during an incident.
Scenario playbooks, not one general procedure
Ransomware, business email compromise, data exfiltration, insider action and a critical supplier outage behave differently and need different first moves. A single general procedure covers all of them badly. Three or four scenario playbooks, each two pages, cover the realistic cases well and are actually read.
Exercised, because that is where the plan gets fixed
A tabletop exercise finds the gaps that reading never does: the contact who left, the decision nobody could make, the assumption that a system would be available. NIST frames its guidance around preparing for incident responses, and exercise is where preparation becomes real rather than documented.
Available when the network is not
A plan stored only on the file share, or only in the collaboration platform, is unavailable in exactly the incidents where it matters most. Printed copies with the people who need them, plus a copy held outside the environment, is unglamorous and it is the difference between having a plan and having had one.
Is this an incident, who decides, and can we take that system offline.
Almost every plan we review answers none of the three in a way somebody could act on at two in the morning.
- Is this an incident. A threshold expressed as observable conditions, not as a judgement about severity, so the person on call can apply it without needing to be the most senior person available.
- Who decides. A named individual and a named deputy, reachable by a route that does not depend on the corporate network or corporate email, both of which may be unavailable or untrusted.
- Can we take that offline. Pre-authorised containment decisions with a named authoriser and a clear boundary, because the delay between recognising containment is needed and being permitted to do it is where most damage accumulates.
- Everything else in a plan matters less than these three. A two-page document that answers them well is more valuable than a forty-page document that answers them in principle and cannot be found during the incident.
Four things that make a plan work on the day.
We agree the decisions before we write the document
Who declares, at what threshold, who can take systems offline, who can authorise spend, who speaks externally. Those are the plan. A document written before those are agreed is a well-formatted set of open questions, and the questions get asked again at the worst possible moment.
We keep it short enough to be read under pressure
A core plan somebody can read in ten minutes, with two-page scenario playbooks for the realistic cases. Length correlates negatively with use. The comprehensive plan that covers every eventuality is the one nobody opens, because at two in the morning nobody is reading forty pages.
We verify the contact pack by calling it
Incident response retainer, insurer with the policy number, legal counsel, regulator route where an obligation exists, critical suppliers and vendor account teams. An untested contact list is a list of assumptions. Calling each one in peacetime takes an afternoon and reliably finds two or three that are wrong.
We exercise it before we call it finished
A tabletop with the actual response team, against a scenario relevant to the business. The exercise output is a correction list rather than a score, because the point is to find the gaps while they are cheap. A plan that has never been exercised is a draft, regardless of how well it reads.
Four phases, and the exercise is where the plan is finished.
- 01Weeks 1 to 2
Establish the decisions before the document
Who declares an incident, at what threshold, who authorises containment, who authorises spend, who speaks externally and who notifies whom. Those decisions are the plan. Writing the document before agreeing them produces a well-formatted set of unanswered questions.
- Declaration threshold expressed in observable conditions
- Named decision makers with named deputies
- Pre-authorised containment boundaries
- Spend authority for external response agreed in advance
- 02Weeks 3 to 4
Write it short, and build the contact pack
A core plan short enough to be read during an incident, with scenario playbooks of about two pages each. Then the external contact pack: responders, insurer, legal, regulator where applicable, critical suppliers and vendor account teams, verified rather than copied from an old document.
- A core plan of a length somebody will actually read
- Scenario playbooks for the realistic cases
- A verified external contact pack, tested by calling
- Out-of-band communication arrangements agreed
- 03Weeks 5 to 6
Exercise it, and fix what the exercise finds
A tabletop with the people who would actually respond, run against a scenario relevant to your business. The output is not a pass or fail, it is a list of corrections: the contact who has left, the decision nobody felt able to take, the system everyone assumed would be available.
- A tabletop exercise with the real response team
- A findings list from the exercise, not a certificate
- Plan corrected against what the exercise revealed
- Second exercise scheduled before the engagement closes
- 04Ongoing
Keep it current, because it decays quietly
People leave, numbers change, systems are replaced and suppliers change. A plan decays without anybody noticing, and the decay is invisible until the plan is used. A short quarterly check of contacts and a documented review after any material change is what keeps it usable.
- Quarterly contact verification
- Review after any material change to people or systems
- An exercise at least annually, ideally more often
- Offline copies refreshed when the plan changes
Six UAE situations where a plan gets written, and one where it should have been.
A regulated firm with a notification obligation
Where an obligation requires notification within a defined window, the clock starts at a point somebody has to recognise. That makes the declaration threshold and the escalation path a regulatory control rather than an operational preference, and it needs to be written, exercised and evidenced rather than understood.
An organisation renewing cyber insurance
Insurers increasingly ask whether a plan exists, when it was last exercised, and whether the notification route is documented. Those three questions are answerable in a sentence each if the work has been done and are uncomfortable if it has not. The notification route with the policy number belongs in the plan itself.
A group where the answer to who decides is unclear
Multi-entity groups have the hardest version of this problem, because the person who can authorise taking a subsidiary system offline may be in another company and another time zone. Working that out during an incident costs hours. Working it out in advance costs one meeting.
An operator where disconnecting means stopping production
Containment is straightforward when the cost of disconnecting is inconvenience. It is a genuine business decision when disconnecting halts a plant, a line or a berth. That decision cannot be made by IT and it cannot be made quickly unless the authority and the boundary were agreed beforehand.
A healthcare organisation where systems cannot simply be turned off
Clinical systems change the containment calculation entirely, and the plan has to reflect that with clinical input rather than assuming a standard playbook applies. What the plan must contain is who makes that trade-off, on what information, and what the fallback to manual process looks like.
An organisation that has just watched a peer be attacked
The cheapest possible prompt, and the best time to do this work. Attention is available, the board is asking, and nobody is under pressure. A plan written and exercised in that window costs a fraction of one written during the aftermath of your own incident, and it is considerably better.
How UAE organisations are prepared for an incident.
| Feature | Exercised and current | A plan that has never been used | No plan |
|---|---|---|---|
A written plan exists | Yes | Yes | No |
Available when the network is not | Yes | No | Not applicable |
Declaration threshold actionable | Yes | Vague | Not applicable |
Containment pre-authorised | Yes | No | No |
Contacts verified | Yes | Stale | None |
Scenario playbooks | Yes | One general procedure | No |
Exercised in the last year | Yes | No | No |
External responders identified in advance | Yes | No | No |
Insurer notification route known | Yes | Rarely | No |
First hour of a real incident | Structured | Improvised | Chaotic |
Five scenarios, and how the first hour differs in each.
| Scenario | What the first hour is about | The decision that cannot wait | |
|---|---|---|---|
| Ransomware | Determining spread and stopping it, before anything else | Whether to disconnect, and who is permitted to authorise it | |
| Business email compromise | Establishing what the account did, and whether money has moved | Contacting the bank, and who can instruct a recall | |
| Data exfiltration | Establishing what left, when, and whose it was | Whether a notification obligation has been triggered | |
| Insider action | Preserving evidence before the person is aware | Who is told, and in what order, including HR and legal | |
| Critical supplier outage or compromise | Establishing your exposure through their access and their data | Whether to sever the connection, and who owns that relationship |
Five steps, ending with an exercise rather than a document.
- 1
Establish the decisions and the obligations
Who declares an incident and at what threshold, who authorises containment and within what boundary, who authorises emergency spend and up to what value, who speaks externally, and what notification obligations apply from regulation, contract or insurance. These are agreed before anything is written.
- 2
Write a core plan somebody will read
Short, with the three questions that matter answered on the first page: is this an incident, who decides, and what can be taken offline. Roles with named individuals and named deputies. Communication arrangements that do not assume the corporate network or corporate email are available or trusted.
- 3
Build scenario playbooks for the realistic cases
Ransomware, business email compromise, data exfiltration, insider action and critical supplier compromise, each around two pages, because the first hour genuinely differs between them. A single general procedure covers all of them badly and reads as though nobody had a specific incident in mind.
- 4
Assemble and verify the contact pack
Responders, insurer with the policy number and notification route, legal counsel, regulator where applicable, critical suppliers and vendor account teams. Then verification by contacting each one, because an untested list is a list of assumptions and typically two or three of them are wrong.
- 5
Exercise, correct, and schedule the next one
A tabletop with the real response team against a scenario relevant to your business, producing a correction list rather than a score. The plan is updated against what the exercise found, offline copies distributed, and the next exercise scheduled before we finish, because that is what stops the plan decaying.
What organisations ask about incident response plans.
Fifteen questions to ask about the plan you already have.
Could you find it
- Where is it stored?If the answer is only the file share, that is a finding.
- Is there an offline copy?With the people who would need it.
- When did anyone last open it?Access logs answer this honestly.
- How long is it?Length is inversely related to use.
- Would a new joiner understand it?They may be the one on call.
Could you act on it
- What is the declaration threshold?Observable conditions, not a judgement.
- Who declares, and who deputises?Both named, not roles.
- Who can take a system offline?Pre-authorised, with a boundary.
- Who can authorise emergency spend?And up to what value.
- Who speaks to customers and press?Decided now, not then.
Is it current
- Are all the contacts still employed?Check, do not assume.
- Have the numbers been dialled?A contact pack is untested until called.
- Does it reference systems you still run?Plans outlive platforms.
- Is your insurer notification route in it?With the policy number.
- When was it last exercised?If never, it is a draft.
The pages around this one.
Ask three people where the incident response plan is stored. Then ask when they last opened it.
If the answer to the first is the file share and the answer to the second is never, you have the two most common findings already. Both are fixable in weeks, and neither is fixable during an incident.
