Overview of this book

As Linux continues to gain prominence, there has been a rise in network services being deployed on Linux for cost and flexibility reasons. If you are a networking professional or an infrastructure engineer involved with networks, extensive knowledge of Linux networking is a must. This book will guide you in building a strong foundation of Linux networking concepts. The book begins by covering various major distributions, how to pick the right distro, and basic Linux network configurations. You'll then move on to Linux network diagnostics, setting up a Linux firewall, and using Linux as a host for network services. You'll discover a wide range of network services, why they're important, and how to configure them in an enterprise environment. Finally, as you work with the example builds in this Linux book, you'll learn to configure various services to defend against common attacks. As you advance to the final chapters, you’ll be well on your way towards building the underpinnings for an all-Linux datacenter. By the end of this book, you'll be able to not only configure common Linux network services confidently, but also use tried-and-tested methodologies for future Linux installations.

Technical requirements

In this chapter's examples, we will use pre-packaged virtual machines, either based on Suricata-Elasticsearch-Logstash-Kibana-Scurius (SELKS) or Security Onion (two different pre-packaged Linux distributions). As in our packet capture examples, IPS solutions often operate against captured traffic, so you may need to refer to Chapter 11, Packet Capture and Analysis in Linux, to ensure you have an appropriate SPAN port configuration. More commonly, though, IPS solutions operate in line with the packet stream, usually with some decryption functionality – so, you may find yourself comparing the architecture more to our load balancer examples from Chapter 10, Load Balancer Services for Linux.

As IPS installations change frequently, this reflects on the installations for these two distributions. Because of this, we won't walk through installing packages and so on in this chapter, so please refer to the online installation for whichever solution...
