Network security is one of today’s most important IT functions. Inline security, specifically, refers to solutions deployed in the flow of live network traffic and used to identify and prevent cyberattacks and other security incidents. The goal of this book is to clarify the most frequently encountered concepts of inline security and be a resource as you develop your network security architecture. For each of the 20 terms included, we provide a simple definition, common use cases, and important considerations for deployment. With a better understanding of the concepts of inline security, we hope you will find it easier to strengthen your defences and protect your organization’s assets.
