Introduction—101 Labs
Welcome to your 101 Labs book.
When I started teaching IT courses back in 2002, I was shocked to discover
that most training manuals were almost exclusively dedicated to theoretical
knowledge. Apart from a few examples of commands to use and
configuration guidelines, you were left to plow through without ever knowing
how to apply what you learned to live equipment or to the real world.
Fast forward another 17 years, and little has changed. I still wonder how—
when around 50% of your examination marks are based on hands-on skills
and knowledge—most books give little or no regard to equipping you with
the skills you need to both pass the exam and then make money in your
chosen career as a network, security, or cloud engineer (or whichever career
path you choose).
101 Labs is NOT a theory book
; it’s here to transform what you have
learned in your study guides into valuable and applicable skills you will be
using, from day one, on your job as a network engineer. For example, Mark
and I won’t be teaching you about SSH per se; instead, we show you how to
configure a SSH connection. If the protocol isn’t working, we show you what
the probable cause is. Sound useful? We certainly hope so.
We choose the most relevant parts of the exam syllabus and use free software
or free trials (whenever possible) to walk you through configuration and
troubleshooting commands step by step. As we go along and your confidence
grows, we will also be increasing the difficulty level. If you want to be an
exceptional network security engineer, you can also make your own labs up,
add other technologies, try to break them, fix them, and do it all over again.

101 Labs—CompTIA Security+
This book is designed to cement the theoretical knowledge you have gained
from reading or watching your Security+ study guide or video training
course. If you have yet to study up on the theoretical side of things, please
check out our cutting edge video and labs on our sister website,
https://www.howtonetwork.com
; our course also features practice exams that
may come in handy.
The goal of this book is to dramatically improve your hands-on skills and
speed, enabling you to succeed in the practical portions of the Security+
exam and also to transfer your skills to the real world as a network security
engineer. We don’t have space here to cover anything theoretical, so please
refer to your Security+ study guide to get a good understanding of the
learning points behind each lab. Every lab is designed to cover a particular
theoretical issue, such as the configuration requirements of SSH, for example.
If you want to become CompTIA Security+ certified, there’s one exam you
must first pass:
SY0-601
We’ve done our best to hit every topic mentioned in the exam syllabus on the
CompTIA website. However, please do check the syllabus on their website,
for they may change as time goes on. Their website also gives more details
on the weighting given to each subject area.
It’s also worth noting, that once we show you how to configure a certain
service or protocol a few times, we stop walking you through the steps in
subsequent labs—to save valuable space. Anyway, in times of uncertainty,
you can always flick back a few pages to see check how it’s done.
We’ve done our best to keep the topology as simple as possible. For this
reason, almost all labs have been configured on a virtual machine (with
internet access).
Please do check out our resource page, which will cover any additional
information you need, and other material that are bound to prove useful:
