The Cybersecurity Playbook for Modern Enterprises

By: Jeremy Wittkop

Overview of this book

Security is everyone's responsibility and for any organization, the focus should be to educate their employees about the different types of security attacks and how to ensure that security is not compromised. This cybersecurity book starts by defining the modern security and regulatory landscape, helping you understand the challenges related to human behavior and how attacks take place. You'll then see how to build effective cybersecurity awareness and modern information security programs. Once you've learned about the challenges in securing a modern enterprise, the book will take you through solutions or alternative approaches to overcome those issues and explain the importance of technologies such as cloud access security brokers, identity and access management solutions, and endpoint security platforms. As you advance, you'll discover how automation plays an important role in solving some key challenges and controlling long-term costs while building a maturing program. Toward the end, you'll also find tips and tricks to keep yourself and your loved ones safe from an increasingly dangerous digital world. By the end of this book, you'll have gained a holistic understanding of cybersecurity and how it evolves to meet the challenges of today and tomorrow.

Testing the system

When you automate a task, sometimes you will have a more efficient and more effective method of achieving a necessary goal and it will be an overwhelming success. Other times you will have an outcome that is neither efficient nor effective, and it will be clear that you should return to the previous way of doing things and try again. Often, it will be somewhere in the middle. How do you test a system you have built? What is an acceptable error rate? How do you measure it?

First, we will talk about a framework for measuring test results known as the confusion matrix.

The confusion matrix

For each task, there are four possible outcomes. These four outcomes are collectively known as the confusion matrix. The following diagram is a visual representation of this simple concept:

When testing systems, each outcome will fall into one of these categories. Here is a brief description of each:

  • True...
