The CISO Decision Brief

If…, then how…

If the board asks "are we secure?", then how do I answer honestly?

The short answer

Recommendation
Answer "are we within the risk the board agreed to carry?" and give one of three positions in one sentence: within appetite; outside appetite, within tolerance; or outside tolerance. If the board has never set an appetite, say you cannot yet answer and ask it to set one.
Reasoning
No organisation is simply secure, and a confident "yes" goes in the minutes and is hard to live with after an incident. The board can judge one thing: whether the risk it carries is within the level it set. One top risk past its tolerance limit makes the whole position outside tolerance, whatever the other measures say. Trust comes from accurate answers, so a figure you do not have is promised by a date, never guessed.
Considerations
  • The top body depends on how you are governed: the board, a board risk committee it has delegated to, the management board in a two-tier structure, or executive management where there is no board.
  • An appetite that says only "low" cannot be tested against the register. It needs a level for each kind of risk.
  • A certificate shows a management system works. It does not show a risk is within appetite.

Read as text

The same flow written out: each step, its reasoning and where the pack covers it. 16 steps.
  1. Start

    A director asks: "Are we secure?"

    The board will judge the organisation's security partly by whether it trusts the person reporting. Trust comes from accurate answers, not confident ones. A 'yes' goes in the minutes and is hard to live with after an incident; a vague 'mostly' tells the director nothing.

    In the pack

  2. Step

    Answer it as "are we within the risk we agreed?"

    Security is not a state an organisation reaches. What the board can judge is whether the risk it carries is within the amount it agreed to carry. That is the one question only the board owns, because it set the appetite. Say so in a sentence, then answer that question.

    In the pack

  3. Decision

    Has the board approved a cyber risk appetite?

    Without an appetite there is no yardstick, so there is no position to report. An appetite that says only 'low' cannot be tested either. It needs a level for each kind of risk that a register score can be compared with.

    In the pack

  4. Outcome

    Say you cannot yet answer, and ask the board to set one

    Say: 'The board has not yet set a cyber risk appetite, so we cannot say whether our exposure is acceptable.' Do not invent a position. Make agreeing an appetite the first decision you put to the board, drafted from the register and agreed by the executives who own each kind of risk.

    In the pack

  5. Decision

    Do you have the current, signed-off position to hand?

    The answer should come from the figures signed off for this meeting, not from memory. If you do not have them with you, say so and promise the position by a date. A position guessed in the meeting goes in the minutes.

    In the pack

  6. Decision

    Is any top risk past its tolerance limit?

    The position follows a rule, not a feeling. One top risk past its own tolerance limit makes the whole position 'Outside tolerance', however many others are within appetite and whatever the other measures say.

    In the pack

  7. Step

    Lead with "outside tolerance" and the decision it needs

    Say it first, before any good news. The board must decide, not just note: fund or order treatment, accept the risk explicitly and record why, or change the appetite. If there is no decision on the agenda, say one is needed.

    In the pack

  8. Decision

    Is any top risk above appetite?

    Above appetite but within tolerance means a risk the board accepted for a time, while a plan brings it back. The board allowed it for a time; it is not 'secure' either.

    In the pack

  9. Step

    Say "outside appetite, within tolerance", with the plan

    Name how many top risks are above appetite, that none is past tolerance, and the plan and date to bring each back. The board may note the plan, challenge it, or decide if it needs money or a change of priority.

    In the pack

  10. Step

    Say "within appetite", and what that does not mean

    Every top risk is at or below the level the board accepted. That does not mean nothing can happen: it means the risks carried are the ones the board chose to carry. If every measure has been on target quarter after quarter while incidents happen elsewhere, check the targets: the pack treats that as a sign of measuring the wrong thing.

    In the pack

  11. Step

    Add the count, the movement and the date back

    One sentence: how many of the top risks are above appetite and past tolerance, how that compares with last time, and when each will be back within appetite. That is the whole answer; the rest supports it.

    In the pack

  12. Step

    Do not reassure beyond the evidence

    Avoid 'we are fully protected', 'it could not happen here' and an unqualified 'we are compliant'. Say instead that a control is in place, when it was tested, and that it reduces the risk without removing it. A certificate shows a management system works; it does not show a risk is within appetite.

    In the pack

  13. Step

    Label facts, estimates and opinions

    'The figure is…', 'We estimate…', 'My view is…'. A director should never mistake one for another. If asked whether you have been breached, say what you have found no evidence of, and what you would be able to see.

    In the pack

  14. Decision

    Was there a figure or fact you did not have?

    'I don't know' is a complete and acceptable answer when it is followed by what you would need to find out, and when. A figure said in the meeting goes in the minutes and outlives the meeting, so never guess one.

    In the pack

  15. Outcome

    Promise the answer by a date, and send it

    Give a date, normally within 5 working days in the pack's defaults. Have it recorded as an action, and send a one-page written answer to the chair through the board secretary by that date.

    In the pack

  16. Outcome

    Answered: the minutes record the position, not a promise

    The board now knows where it stands against its own appetite, in words it can hold you to. Afterwards, add the question and the answer that worked to your own copy of the question bank.

Practical checklist

  1. Check that the board has approved a cyber risk appetite you can compare the register with.
  2. Bring the figures signed off for this meeting, not numbers from memory.
  3. Check whether any top risk is past its tolerance limit, then whether any is above appetite.
  4. Lead with the position and the decision it needs. Put bad news first.
  5. Add how many top risks are above appetite and past tolerance, which way that is moving, and when each will be back.
  6. Label each statement as a fact, an estimate or an opinion.
  7. If you do not have a figure, promise it by a date (normally within 5 working days in the pack's defaults) and send a one-page answer to the chair through the board secretary.

Evidence to have ready

  • The board-approved risk appetite statement and the top-risk extract from the risk register.
  • The signed-off Board Reporting Data Collection Workbook, which every figure you quote comes from.
  • The action recorded for any answer you promised, and the one-page written answer you sent by that date.

Assumptions

  • Your risk register scores the top risks, and the board follows them by name.
  • The top body depends on how you are governed: the board, or a board risk committee it has delegated to; the management board in a two-tier structure; executive management where there is no board.
