The CISO Challenge: Articulating Data Worth and Security Economics

A few years ago the former eBay’s CISO, Dave Cullinane, led a sobering coaching discussion on how to articulate and communicate the value of a security solution and its economics to a CISO’s CxO peers.

Why would I blog about such old news? Because it was a great and timeless idea. And in this age of the ‘Great Data Breach’, where CISOs need all the help they can get, I thought I would share it with y’all.

Dave began by describing how to communicate the impact of an attack from malware such as Aurora, spearfishing, stuxnet, hacktivision, and so on… versus the investment required to prevent the attack.  If you are an online retailer and your web server goes down because of a major denial of service attack, what does that cost the business?  How much revenue is lost every minute that site is offline? Enough to put you out of business? See the figure below that illustrates how to approach this conversation.

If the impact of a breach and the risk of losing business is high and the investment in implementing a solution is relatively low, the investment decision is an obvious one (represented by the yellow area in the upper left corner).

However, it isn’t always this easy, is it?  When determining what your company’s brand and reputation worth, how do you develop a compelling case?

Another dimension Dave described is communicating the economics of a solution that could prevent an attack based on the probability that the attack would occur (see next figure below).

For example, consider an attack that could influence stock prices?  This is a complex scenario that is probably less likely to occur on a frequent basis and would require a sophisticated multidimensional solution with an integrated security analytics solution to correlate multiple events back to a single source.  This might place the discussion in the middle blue box, or the ‘negotiation zone’. This is where the CISO needs to know what the CxO’s risk tolerances are and articulate value in terms of the ‘coin of the realm’.

Finally, stay on top of what the business is cooking up for new initiatives that could expose or introduce new risks.  For example, is marketing looking to spin up a data warehouse on Amazon Redshift? Anyone on the analytics team tinkering with Hadoop in the cloud? Is development planning to outsource application test and development activities to offshore systems integrators? If you are participating in any of these activities, make sure your CISO isn’t the last to know when a ‘Breach Happens’!
