Do network economics matter? Value of network to one user Total value of a network Security economics Security risk management Hacker economics Economics of deterrence Supply chain incentives Economics of Internet protocols (architecture) Economics of outages Economics of resiliency (correlation of losses) 29Jul09

Metcalfe’s Law 29Jul09 fax networks is larger today than ever, but less valuable because of substitutes such as email, Fedex, UPS, PDF’s, web, etc., thus the model does not hold Where: V = value of network j n = the number of end points or nodes p = some constant V j = n 2 * p Historic Network Value Models

New Model: Beckstrom’s Law Economics of Networks 29Jul09 The value of a network equals the net value added to each user’s transactions, summed for all users.

V i,j = ΣB - ΣC Where: V = value of network j to user i B = the benefit value of all transactions C = the cost of all transactions Value of a Network to One User New Network Model 29Jul09

V = B - C V = $26 - $16 V = $10 If it costs $26 to buy the book in a store or $16 to buy it over the Internet, including shipping, the net value is $10. Online Book Purchase Case 29Jul09

V[j] = ΣV i,j = ΣB - ΣC Network Value is Summation of Value to All Users New Network Model 29Jul09

29J ul09 Where: ΣV i,j = value of a network j to all users V i,j = net present value of all transactions to user i with respect to network j, over any time period j = identifies one network i = one user of the network B i,k = the benefit value of transaction k to individual i C i,l = the cost of transaction l to individual i r k and r l = the discount rate of interest to the time of transaction k or l t k or t l = the elapsed time in years to transaction k or l n,m,p = maximum number of individuals i and transactions k and l Beckstrom’s Law New Network Model

The “Network Effect” 29Jul09

For those networks where… The “Network Effect” 29Jul09 More users add to more total value

For those networks where… The “Inverse Network Effect” 29Jul09 More users reduce total value <

Private Golf Clubs AARP Support groups Costco FaceBook Coops YPO Your social networks Twitter Your customers Internet … Examples 29Jul09

Where: SI = Security Investments L = Losses C’ = C – SI – L (all costs except SI & L) V = B - C’ - SI - L Security Model V = B - C Economics of Security Basic Model V = B - C 29Jul09

Minimize Security Costs = SI + L The Fundamental Security Risk Management Function Economics of Security 29Jul09

Loss $ Security Investment $ 0 Pareto Chart of Best Security Investments Against Losses (hypothetical curve) Economics of Security 29Jul09

Loss $ Security Investment $ 0 Different security technology investments can be ranked in order of payoff (reduced losses per dollar of investment). IP Patch IDS DLP Economics of Security 29Jul09

Loss $ Better network protocols can drive Loss function down for most or all users. Security Investment $ 0 Economics of Protocols 29Jul09

Minimize the Hacker’s Gain Minimize V = B - C’ - SI - L For example, by seeking to reduce their Benefit or take. Increase their operating costs (making stealing more difficult). Force them to invest more in their own Security Investments (making it harder for them not to get caught). Increase their losses by improving enforcement and increasing penalties and imprisonment, for example. Economics of Deterrence 29Jul09
