Rafal Los is the Director of Solutions Research at Accuvant. He produces the Down The Security Rabbithole podcast and writes the Following the Wh1t3 Rabbit security blog. On several occasions he's tackled the CISO role within an organization on both his podcast and blog. I would highly recommend both if you're in the infosec field or looking to get into it. In the interview Rafal talks about: what a CISO is; the role of a CISO; the skills; and different types of CISOs.
