Foreword
Newly promoted CISOs rapidly realize that the scope of the position they have taken on
is often beyond what they have been prepared for. The nature of securing an enterprise
is daunting and overwhelming. There are no simple checklists or roadmaps for success.
Many of the technical security skills a CISO has acquired during the early portion of his or
her career may provide a “sixth sense” or intuition, but technical expertise alone does not
prepare the CISO for the business and leadership challenges required for success.
The Dunning-Kruger effect “is a cognitive bias in which unskilled individuals suffer
from illusory superiority, mistakenly rating their ability much higher than average”
(Wikipedia). Successful CISOs generally realize and admit to themselves how much they
don’t know. In my career, I have met many senior security professionals and have noticed
a common set of traits among those who are successful.
They generally exhibit a strong sense of curiosity, the ability to be self-aware, the
ability to “think evil” (like the adversary), and have strong communication and critical
thinking skills. They are open to new ideas, they invite debate, and they are adaptive in
their thinking and positions when new information is presented. They develop leadership
skills and build structures that enable balance. They also recognize talent and surround
themselves with teams of capable security technologists who are the true experts.
Excellent security leaders have learned that risk is not black-and-white and that balance
needs to be applied. They are empathic and likeable. My friend Malcolm meets all these
criteria.
In Managing Risk and Information Security: Protect to Enable, he distills the
hard-acquired knowledge he has learned through his career as a business and security
leader into a concise framework that enables CISOs to cut through the chaos of securing
the enterprise. Absorb the lessons in this book and enrich them by continuing to
experiment and innovate. Threats, organizational dynamics, and technology are constantly
evolving and we as security professionals must apply the lessons outlined here and
continuously adapt ourselves to the challenge.
