Overview of this book

It's not a secret that there is a huge talent gap in the cybersecurity industry. Everyone is talking about it including the prestigious Forbes Magazine, Tech Republic, CSO Online, DarkReading, and SC Magazine, among many others. Additionally, Fortune CEO's like Satya Nadella, McAfee's CEO Chris Young, Cisco's CIO Colin Seward along with organizations like ISSA, research firms like Gartner too shine light on it from time to time. This book put together all the possible information with regards to cybersecurity, why you should choose it, the need for cyber security and how can you be part of it and fill the cybersecurity talent gap bit by bit. Starting with the essential understanding of security and its needs, we will move to security domain changes and how artificial intelligence and machine learning are helping to secure systems. Later, this book will walk you through all the skills and tools that everyone who wants to work as security personal need to be aware of. Then, this book will teach readers how to think like an attacker and explore some advanced security methodologies. Lastly, this book will deep dive into how to build practice labs, explore real-world use cases and get acquainted with various cybersecurity certifications. By the end of this book, readers will be well-versed with the security domain and will be capable of making the right choices in the cybersecurity field.

Transformations in cybersecurity

Hackers in the early 2000s began experimenting with many security evasion tactics to beat the existing security tools. They had already come up with techniques to evade security tools on networks. They had also come up with a new attack method called a buffer overflow. A buffer overflow is conducted mostly on client/server apps, where payloads are delivered with data specifically aimed to fill and write outside memory buffers. For instance, hackers would supply scripts to log in input fields in a client app, which would cause the server to import files. Since the server would be expecting just a few characters in the input field, the excess data would cause a buffer overflow, causing it to fail or function erroneously. Exploit toolkits were also being modified to include security evasion tactics.
