Course Overview
Hi everyone, and welcome. My name is Andrew Mallett, but you may also know me as The Urban Penguin. We look today at extending LPIC level 2 courses we have by adding in Topic 212, security services, and enrolling you as one of the men in black. Linux does not need securing. We all know that. Well, think again. Security of an operating system is all about the deployment and the ongoing monitoring, not so much its particular flavor. We will teach you what you need to know to manage security in Linux and how to protect your valuable IT assets. During this course, we're going to show you, among other topics, how you can create networks and routing tables, helping you isolate servers and services from threats. You'll be looking at firewall in Linux, blocking access to services, and providing internet access through to your clients using NAT. You'll also be looking at how we can access services from the internet using port forwarding. Finally, we're going to move on to assessing vulnerabilities on our system using OpenVAS, as well as using Snort to detect intruders on our system. By the end of this course, you will have gathered the knowledge required for Topic 212 of the Linux Professional Institute exam 202-450 along with the skills required to secure Linux servers on your network. In order to complete this course, you will need good Linux command- line skills and the ability to install Ubuntu 16. 04 Server.
