The short answer

Recommendation
Rank by risk position, not by project. Take out what the budget already carries, fund risks outside tolerance first, then those outside appetite, and for each risk the money cannot cover, decide openly: phase the work, accept the risk at the right level, or put the gap to the board as a decision.
Reasoning
A fixed budget turns priorities into trade-offs. Ranking by each risk's position against the board's appetite lets every choice be explained in the words the board already sees. A risk outside tolerance takes the first call, because leaving it unfunded is a decision only the board or its equivalent can take (rule RM-08). A risk within appetite needs no new decision. Silence leaves a risk outside appetite with nobody having decided, and one kept there for more than a quarter without a treatment decision is reported by name to executive management (rule RM-12).
Considerations
  • The top approver 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.
  • Without an approved risk appetite, any ranking rests on your own judgement. Make agreeing one your first ask.
  • The pack sets no order within each group. Whether an action brings its risk back within appetite is one fair test.
  • This works inside the budget you are given. It does not size the budget.

The same flow written out: each step, its reasoning and where the pack covers it. 17 steps.
  1. Start

    Next year's budget is fixed; you must choose what to fund

    A fixed budget turns priorities into trade-offs. The basis that holds up is the risk position the board already sees each quarter, so every choice can be explained in the same words. Each funded item should trace back to a risk and its position.

    In the pack

  2. Step

    List each top risk with its position against appetite

    Take the risks from your register with their residual band and category. Each one is within appetite, outside appetite but within tolerance, or outside tolerance. The quarterly risk report already shows this by risk and by category, with the treatment actions attached.

    In the pack

  3. Decision

    Has the board set a cyber risk appetite?

    Without an approved appetite, nobody can say which risks are acceptable, so any ranking rests on your own judgement alone. Each category of risk should have an appetite level approved by the board.

    In the pack

  4. Step

    Make agreeing an appetite your first ask

    Tell the board plainly that it has not yet set a cyber risk appetite, so you cannot say whether exposure is acceptable, and ask it to agree one. An appetite statement is usually a few sentences, each allowing a risk to be judged inside or outside it. Until one is agreed, the ranking below rests on your own judgement; the pack sets no rule for it.

  5. Step

    Take out what the budget already carries

    Part of next year's money is already spoken for. Actions done in earlier years add running costs every year, and actions already approved and under way need finishing. The treatment plan shows both: running cost per year, and what is approved, under way or done. What is left is what you can choose with.

    In the pack

  6. Step

    Cost each candidate action and its expected effect

    For each action, record an owner, a due date, the one-off cost, any running cost per year, and the residual score expected when it is done. Staff time can be costed where it competes with other work. The expected position after shows whether the action brings the risk back within appetite.

    In the pack

  7. Decision

    Is any risk outside tolerance?

    Tolerance is the point at which the board said it must act, not just be told. A Critical residual risk is always outside tolerance. These risks take the first call on the budget, because leaving one unfunded is itself a decision only the board can take.

    In the pack

  8. Step

    Put these first; each needs a board decision

    For each risk outside tolerance the board decides: fund or order treatment, accept the risk explicitly and record why, or change the appetite. Only the board or its equivalent may accept it: the board, or a board risk committee it has delegated to; in a two-tier structure, the management board; where there is no board, executive management.

    In the pack

  9. Step

    Rank the rest: outside appetite first, then slipping risks

    Next come actions that bring a risk outside appetite back within it. Then actions that stop a risk within appetite from slipping. A risk within appetite needs no new decision, though its owner may still reduce it where that is cheap. The pack sets no order within each group; whether an action's expected position after is within appetite is one fair test.

    In the pack

  10. Decision

    Does the budget cover every risk outside appetite?

    Add up the ranked actions until the money runs out. Look hard at what falls below the line: each is a risk the organisation will carry for another year unless something changes.

    In the pack

  11. Decision

    What will you do about each unfunded risk?

    Every risk outside appetite needs a treatment decision, and one kept outside appetite for more than a quarter without one is reported by name to executive management. Silence leaves it outside appetite with nobody having decided. There are three routes: do less or later, carry the risk knowingly, or take the gap to the people who can change the priority or the money.

    In the pack

  12. Step

    Phase the work or choose a cheaper action

    Fund now the part that reduces the risk most and leave the rest for the next budget, as one of the options in the pack's worked board decision does. Record the residual expected after the funded part only. If the position after is still outside appetite, add actions or record an acceptance for what remains.

    In the pack

  13. Step

    Accept what remains, at the level the band sets

    Accepting is a treatment choice with named approvers. The residual band sets who may accept; a risk outside appetite needs executive management as well, never instead. Outside tolerance, only the board or its equivalent may accept. Each acceptance is recorded and reviewed by a date.

    In the pack

  14. Step

    Write the gap up as a decision for the board

    State the decision in one sentence, why now, at least two real options with what each achieves and costs, your recommendation, the risk of not deciding, and who has agreed. The board decides appetite, priority, money above management's authority and acceptance above tolerance. Choosing products or suppliers stays with management.

    In the pack

  15. Step

    Write the plan and have each risk owner approve it

    The treatment plan sets the period, the risks in scope, objectives with measures of success, and review points. Each risk owner approves the plan and the residual risk it leaves. Funding above your authority goes to whoever your organisation names for it.

    In the pack

  16. Decision

    At each quarter, has any risk's position changed?

    Each quarter, risk owners check that the expected residual is still right and the actions are still the right ones. A trigger such as a major incident, a new threat or an audit finding forces reassessment of the risks it touches. A changed position can change the order.

    In the pack

  17. Outcome

    Each risk is funded, phased or knowingly carried

    The quarterly report to executive management shows the position, its direction, treatment progress and the decisions needed. Carry the same position and decisions into the board report so both say the same.

Practical checklist

  1. List each top risk with its residual band and its position against appetite.
  2. Check that the board has set a cyber risk appetite, and ask for one if it has not.
  3. Take out the running costs of past work and the actions already approved and under way.
  4. Cost each candidate action with its owner, due date, one-off and running cost, and the residual score expected when done.
  5. Fund risks outside tolerance first, then actions that bring risks outside appetite back within it.
  6. Decide each unfunded risk openly: phase the work, accept the residual at the band's level, or write the gap up as a board decision.
  7. Have each risk owner approve the plan and the residual risk it leaves.
  8. Recheck the positions each quarter and after any trigger, and reorder if they change.

Evidence to have ready

  • The treatment plan, with each action's owner, due date, cost and expected residual, and each risk owner's approval.
  • The acceptance record for each risk carried, approved at its band's level and reviewed by its date.
  • The board decision paper for any gap, with its options, costs and recommendation, and the decision taken.
  • The quarterly risk report showing each risk's position, treatment progress and decisions needed.

Assumptions

  • You have a risk register with each risk's residual band and position against appetite, and a treatment plan with costed actions.
  • The budget is given to you. Nothing here suggests how much to spend.
