Hello, everyone, and welcome.
My name is Andrew Mallett,
and you are just minutes away from learning to manage
security in your Linux systems.
Let me introduce you to my latest course, CompTIA Linux+: Security.
Now I'm the owner of The Urban Penguin in the UK,
training and consulting in Linux,
and I've been doing so for a number of years and working both as a
system administrator and a dabbling developer,
working a lot with Python currently,
as well as configuration management systems such as Ansible,
Puppet, and Salt.
Security is paramount,
and learning techniques to secure your system is going to help you
both in your cloud and with your local appliances.
Some of the major topics that we cover include managing your
file permissions and access control lists,
working with mandatory access control lists such as SELinux and AppArmor,
certificate authorities and working with HTTPS,
firewalling.
By the end of this course,
you're going to know how to secure a diverse range of Linux systems,
including those on RHEL‑based systems, Ubuntu and openSUSE.
Before beginning this course,
you should be familiar with working at the Linux command line, skills that you can gain from the RHEL 8: Essential Tools course.
