Right. Security investment can be managed and evaluated with the same
approach as business insurances. Does an insurance produce ROI ? No, it
doesn't, but it lowers the risk to that ROI.
Would you prefer a return of 500$ with a risk of, say, 10%, or a return
of 5000$ with a 90% risk of becoming 0 ? It probably depends on your
investment and your conditions.
These are the questions that managers ask themselves when evaluating,
for instance, wether they can afford insurance against theft, or they
are willing to throw the money to phisical security, or both, or if they
are more willing to cover the eventual cost of theft itself instead.
Whenever anyone talks about ROI in security investment, you should raise
an eyebrow (Gartner reports, anyone ?).
