Introduction
Today, digital technology defines the competitive battleground,
and organizations are constantly striving to improve their
services with new applications. These organizations are
rapidly adopting cloud technologies to keep pace with growing
business demands and take advantage of efficiencies and scalability
in the cloud. As a result, the traditional corporate perimeter is
fading, and mobile workers are driving ever-increasing usage of
SaaS applications. Organizations today are using a mix of private
and public cloud services to gain the cost savings, agility, and speed
benefits of the cloud.
As a result of this digital transformation, risk management and
data protection are top concerns for organizations migrating to
the cloud. IT leaders worry about securing the business. Whether
on-premises, in the cloud, or mobile, the entire IT architecture
must be secure to preserve the integrity and longevity of the
business. Legacy security tools, policies, and processes designed
for traditional data centers and IT operations cannot adapt to
address SaaS applications or the continuous deployment model
and pace of change in the cloud. Although many tools are avail-
able for securing the cloud — including native security services
from public cloud providers — siloed security products, manual
operations, and human errors continue to slow down the business
and create risk. Visibility and control in the cloud are challenging,
and cloud environments are complex.
To be successful, organizations need a consistent approach to
security that spans all of their operating environments, from
on-premises data centers to multiple public and private clouds.
They need tools and processes that simplify operations through
automation driven by machine learning and analytics, and cross-
platform capabilities that prevent data breaches across the cloud,
data center, and endpoints.

About This Book
Cloud Security & Compliance For Dummies consists of six chapters
that explore
» The evolution of cloud computing and cloud security
(Chapter 1)
» How to secure the cloud in your organization (Chapter 2)
» The regulatory landscape in the cloud (Chapter 3)
» How to build an effective cybersecurity team and leverage
automation in the cloud (Chapter 4)
» Coming trends in cloud security (Chapter 5)
» Best practice recommendations for securing the cloud
(Chapter 6)
Finally, if you get lost in all the acronyms and technical terms
used throughout the book, there’s a glossary in the back of the
book to help you out!
Foolish Assumptions
It’s been said that most assumptions have outlived their useless-
ness, but I’ll assume a few things nonetheless:
» You’re a chief information officer (CIO), chief technology officer
(CTO), chief information security officer (CISO), cloud architect,
IT compliance and risk manager, network practitioner, or a
security practitioner.
» You have a general understanding of cloud computing and
how it supports business agility in your organization.
» You need to better understand the scope and breakdown
of cloud risks and how to deploy security in a frictionless
manner to prevent data breaches without negatively
impacting your business and development needs —
today and in the future.

If any of these assumptions describes you, then this book is for
you! If none of these assumptions describes you, keep reading
anyway. It’s a great book and when you finish reading it, you’ll
know quite a bit about cloud security and compliance.
Icons Used in This Book
Throughout this book, I use special icons to call attention to
important information. Here’s what to expect:
This icon points out information that you should commit to your
nonvolatile memory, your gray matter, or your noggin — along
with anniversaries and birthdays!
Tips are appreciated, never expected — and I sure hope you’ll
appreciate these useful nuggets of information. This icon points
out useful nuggets of information.
This icon points out the stuff your mother warned you about.
Okay, probably not. But you should take heed nonetheless — you
may just save yourself some time and frustration!
Beyond the Book
There’s only so much I can cover in 72 short pages, so if you
find yourself at the end of this book, thinking, “Gosh, this
was an amazing book! Where can I learn more?,” just go to
www.paloaltonetworks.com/products/secure-the-cloud.
Where to Go from Here
If you don’t know where you’re going, any chapter will get you
there — but Chapter 1 might be a good place to start! However,
if you see a particular topic that piques your interest, feel free to
jump ahead to that chapter. Each chapter is written to stand on
its own, so feel free to start reading anywhere and skip around to
your heart’s content! Read this book in any order that suits you
(though I don’t recommend upside down or sideways).
