Every small, medium, and large enterprise across the globe today carries out at least a few, if not all, operations with the help of Information Technology (IT). IT networks form the basic building blocks of these complex structures with the help of associated technologies and business logic. Securing such networks is therefore of paramount importance.

In this book, we will learn advanced skills and their real-world implementation, which will enable us to build a resilient network security apparatus, secure existing network infrastructure, and implement a high-fidelity, repeatable improvement plan to stay up to date with the latest cybersecurity threats and how to mitigate them. We will be taking a deep dive into subjects including network penetration testing, network audits, network digital forensics, threat intelligence, threat hunting, deception technology, and attack vectors impacting ICS/SCADA, IoT, and VOIP, among others.

By the end of this book, you should be able to:

• Understand the building blocks of a network and how to apply security to it
• Understand threats and vulnerabilities that commonly plague networks today
• Understand how to perform security testing for your network
• Understand how to imply business impact and risk prioritization for the purpose of remediation and management discussion
• Understand how to move to a proactive security mindset from a reactive security mindset
