I just wrote a paper on the value of information security. Please see the paper here. It is something I have thought about for a long time. Information security as a technical discipline but someone has to pay for all this fun we are having. My assumption is that as Willie Sutton is quoted as saying "Go where the money is...and go there often.” Today where organized crime and nation states are going is to information. It is amazingly easy to monetize certain kinds of information. There is a buyer for everything that hackers can steal. The impact to business has been debated for some time and we go to great lengths to perform risk assessments. What we don't do such a good job of is monetizing that risk.
Consider this. If we can monetize the information asset, we should be able to monetize the risk to that asset. The key to monetizing risk is knowing the value of the asset at risk. Different systems for risk assessment have been in place for some time. They all seem to revolve around professional judgment. My argument is that using a combination of threat modeling (war planning) plus simple asset monetization will allow us to monetize risk. The results will not be perfect, but they should be directionally correct. As Doug Hubbard says it is better to be directionally correct than specifically wrong.
