In light of the recent Epsilon data breach, it seems appropriate to chat briefly about the realities of balancing information risk. First and foremost, we need to make sure that we understand this thing called “risk.” In our context, risk is defined as “the probable frequency and probable magnitude of future loss” (based on Jack Jones’ FAIR definition).

My article, “Maddening Methods: Fundamentals of Risk Assessment and Analysis,” was published in the July 2010 edition of The ISSA Journal. It covers some of the key concerns around risk assessment today, including addressing common arguments posited against risk assessments and risk management.
