Enterprise Linux Security
Securing Red Hat Enterprise Linux 8 is a two day intensive course where you will be shown, in detail, security mechanisms in RHEL 8. The skills that you will learn range from file permissions, POSIX ACLS, Firewalld and SELinux. These skills will help you succeed as a Linux Administrator or gain valuable knowledge for certification exams, both practical and written.
The course is run and facilitated by Andrew Mallett, The Urban Penguin, a prolific YouTuber and author with Pluralsight. Andrew also rights training for OpenSource vendor including LINBIT and their HA software DRBD. You can be guaranteed that these two days will benefit you if you are a new or experienced Administrator or just looking to validate you skills with professional certification.
Understanding the Linux Mode:
Gain full understanding of reading and setting Linux file permissions and which rights are required to run tasks. As well as the standard permissions the course will give you control over special permissions and how they are used. You will be able to use the find command to locate files with additional privileges set.
Working with POSIX ACLS:
Extending the standard permissions with ACLs you will learn to add more users and groups into the permissions set as well as set default permissions for new files. In so doing, you will understand who services such as the Apache Web Server can be run in or more secure environment than it is out of the box .
Firewalls with Firewalld and NFTables in RHEL 8:
Firewalld has been a stable of Enterprise Linux for a while, previously it has operated with iptables at the backend. The nftables framework replaces iptables as a default network packet filtering feature on RHEL 8. You will learn to use Firewalld as an interface to nftables, securing your system from the network.
Mandatory Access Control with SELinux:
SELinux is an absolute requirement to your security in an modern Linux system. You will learn how to implement SELinux keeping your system running the way it needs. Starting the SELinux basics we will soon move onto securing the Apache Web Server and creating custom SELinux modules helping us fully understand SELinux diagnostics and tuning.
To attend this course you should have basic knowledge of Linux administration and be able to work at the Linux command line.

SELinux is the core foundation to Enterprise Security and is all too often disabled without a second thought. This course will help you to understand SELinux and how you can use it to keep your system secure. Using Red Hat Enterprise Linux 8 the course will take you through configuring the different modes of SELinux before moving onto SELinux Users, rules and eventually writing your own modules. The main topics include:
- SELinux modes
- Securing user access with SELinux users
- Understanding Type Enforcement rules
- Using Booleans to simplify security
- Diagnosing SELinux issues
- Using Permissive Domains
- Writing SELinux Modules
By the end of the 4 hour course you will be able you implement SELinux on your systems keeping the environment secure and adjusting SELinux to meet the needs of customized services.
The course is held online and courseware is provided but you will need to provide your own system to work with. Although we use RHEL 8 Enterprise Linux 7 or 8 will work and CentOS is more than ok. You will need root access to the system and we recommend using test virtual machines for the purpose of learning.
