Julian Zelizer: Cyberthreats, by and large, remain an abstract, catch-all notion in many board rooms. Security executives should ask fundamental questions with respect to any specific cyberthreat: Is it material to the business? Zelizer asks: If it isnt, why are we even talking about it? He says CISOs and CISOs should be able to present the risks that are most likely to result in material impact to business. Zelizer says security executives must now determine if that risk is acceptable to business, and if it is, then the CISO can offer mitigating solutions.”]
