Tutorial: Firewalls with NFtables - John Hawley, VMware
Linux networking has gone through many changes over the years, and the ip filtering subsystem is no different. From ipchains, to iptables, and now to nftables, which is quickly becoming the defacto standard for network filtering on Linux. This talk is intended to get users who have a basic understanding of networking an overview of nftables, why it's a major step forward, why it's taken so long, and to get attendees the basics (including examples) they can take to deploy their own network filtering using nftables. This is primarily targeted as a teaching and 101 level discussion, and to give attendees a starting point to go further from. Basic concepts like tcp/ip, udp, network flows and such would be good understandings to have coming in, but the topics will be touched on briefly.

Tutorial: How to Ansible - John Hawley, VMware
Gone are the days when an administrator could, realistically, count the number of machines they were responsible for, and the days of very large scale deployments are here. This also means gone are the days when an admin could reasonably log into all of those machines to do the configuration by hand. Today it's best to rely on an automation framework to do this on a larger, more replicable, scale. Ansible is one such automation framework and this is a intended to walk folks through the very basics of Ansible, getting it set up, up and running, passing data, fetching information and generally getting comfortable with the basics of what configuration management is. This is a hands-on tutorial with specific walkthroughs by using virtual machines provided for the tutorial (a laptop sufficiently capable of running two virtual machines would be required).

Linux Tracing with BPF, BCC and More - Mauricio Vásquez Bernal & Alban Crequy, Kinvolk
BPF is a virtual machine inside the Linux kernel that allows to load user defined programs that are attached to different kernel hooks (kprobes, tracepoints, uprobes, etc). One BPF’s application is to perform tracing at the kernel level as BPF programs can capture information about different kernel events. BCC (BPF Compiler Collection) is a set of libraries for different languages such as Python, C++, Lua and many ready-to-use tracing tools.  This talk will give a quick introduction of BPF. It’ll present an introduction to the BCC project and its features. A demo of the more popular BCC tools will be done. It’ll also show how to create (or customize) your own tools. Finally, it’ll show how BCC is integrated with other projects to perform tracing in cloud environments like Kubernetes.

Monitoring: A New Approach - Tom King, The Linux Foundation
Monitoring consists of Collecting, Storing, Displaying and Graphing operating data for your Systems and networks. We do this to allow us to locate problems, optimize resource usage, notify personnel of issues that need resolving. In this talk, we will talk about where things are going with Monitoring/Alerting and demonstrate some current trends on the subject.

Tutorial: In Linux System Security, WE believe! - Panos Kalorogiannis, National Bank of Greece
The presentation aims and deepens the security of Linux operating systems. Specifically, it concerns system administrators and engineers, system architects, and everyday users in general.  After the presentation, the user will be able to provide optimum security to their system through SELinux, Linux pluggable authentication modules, process monitoring, manage users whether they are regular users or system users, and perform system auditing. In addition, users will be able to scan their system for vulnerabilities and check whether an update is necessary to be applied.  Finally, it would be important to note that to accelerate such actions, automation is important. This will, of course, be achieved through bash scripts.
