Course Description

Overview

Security is always a concern, and with major security holes like Shellshock and Heartbleed being announced regularly, it's more critical than ever to secure the data you are liable for. This course will walk you through the many risks and threats that exist, show you how to use best practices and other open-source tools to mitigate or counteract those threats, and teach you what you need to know to detect and recover from those attacks that do happen.
 

Objectives

In this course students will learn how to assess security risks in your enterprise Linux environment, the best techniques and tools to increase security, server hardening, how to deploy and use monitoring and attack detection tools, how to gain visibility into possible vulnerabilities, the art and science of developing your Linux security policy and response strategy, how to configure your systems for compliance with HIPAA, DISA STIG, etc., and more. This advanced, completely hands-on course adopts a highly technical approach to cover important security techniques and tools. By providing visibility both into attack vectors and possible security holes, this course provides you a complete guide on how to mitigate security risks in any Linux environment.
 

Audience

This course is for individuals already experienced in Linux system administration who want to improve their security posture. Before enrolling, you should have a solid understanding of core local system administration and networking concepts, and be experienced with Linux (or more generally UNIX), especially at the command line level.
 

Prerequisites

    To make the most of of this course, you should: Have a solid understanding of core local system administration and networking concepts equivalent to that obtained from Linux System Administration and LFS311 Linux Networking and Administration. Be experienced with Linux (or more generally UNIX), especially at the command line level.
