問題文
A school foundation is settling the two-part mantel sheet that goes before its risk committee. For the upper mantel the sheet carries nine entries, and the mantel has to give how many of the nine name a vulnerability that something else would have to make use of, rather than a predisposing condition that only raises or lowers the likelihood that harm follows: (1) the one password that three clerks share between them for the ledger account; (2) the campus that stands on the flood plain of the river; (3) the accounting package the supplier stopped issuing fixes for two years ago; (4) the register that nobody has ever tried to restore from its nightly copy; (5) the bursary office that has no line out to any network at all; (6) the rights that stay with a member of staff after the move to another post; (7) the single road by which every delivery reaches the campus; (8) the continuity plan whose call-out list was left half filled in; (9) the term-end reporting tool that lets any reader widen the query beyond their own faculty. For the lower mantel the sheet carries eight statements about aggregation, that is, about rolling several separate risks up into one higher figure, and the mantel has to give how many of the eight the guidelines set down, rather than being claims the guidelines do not make: (1) the rolling up of the separate risks is done chiefly at the level of the whole foundation and of the work stream, and now and then at the level of one system; (2) for a single separate risk, the worst the harm could come to sets the ceiling on the overall figure; (3) that ceiling can fail to hold where several risks come true together, or where the same one comes true again and again; (4) once the rolling up is done, the separate figures need no longer be kept on the register; (5) the amount carried can then go past the room the foundation has to carry it; (6) where a direct or an inverse relation runs between two separate risks, they may be coupled in words or correlated in numbers; (7) the rolled-up figure is arrived at by adding the separate figures together; (8) the coupling is looked for only where the separate risks bear on the same holdings. Which pairing completes the mantel sheet?
