In reality, cybersecurity is not an entry-level job. The
certifications like CEH may be considered “entry-level” within the
cybersecurity domain, but the field itself requires a solid technical
foundation before specialization. Without this foundation, newcomers often feel
overwhelmed, lost, and discouraged when faced with the vast amount of new
knowledge cybersecurity demands. It is critical to understand the fundamentals
of computing, networking, and IT operations before attempting to secure them.
To put it simply, you cannot protect what you do not understand.
This article explores why cybersecurity requires a
foundation in core IT concepts, what those fundamentals include, and how
students can prepare themselves for a successful career by building knowledge
step by step. We will also highlight the importance of risk management and key
cybersecurity principles like confidentiality, integrity, and availability.
Finally, we’ll discuss practical ways for students to get help mastering these
areas through guided tutoring and structured learning.
The
Misconception: Cybersecurity as an Entry-Level Field
One of the biggest issues in the industry today is
marketing. Cybersecurity is presented in glossy advertisements with promises of
high-paying jobs, often paired with quick training programs that suggest anyone
can become a cybersecurity analyst or ethical hacker in just a few months.
While the enthusiasm is commendable, the reality is more complex.
Cybersecurity certifications like CEH, CompTIA Security+,
or CompTIA CySA+ are indeed accessible compared to advanced certifications
such as CISSP or OSCP. However, “accessible” does not mean “beginner-friendly.”
They assume that candidates already have a working knowledge of how computers,
networks, and IT infrastructure function. Without that baseline, the
terminology, tools, and concepts introduced in these certifications feel like
learning a new language without first knowing the alphabet.
This is why so many students who jump straight into
cybersecurity bootcamps find themselves frustrated. They’re not unintelligent
or incapable; they’re simply being asked to climb too steep a hill without the
right equipment. The truth is that cybersecurity is a specialization, not an
introduction. Just as a surgeon must first study anatomy before specializing in
heart surgery, a cybersecurity professional must first understand IT
fundamentals before learning to defend against attacks.
Why a
Strong Foundation Matters
Cybersecurity is all about protecting systems, networks, and
data. But how can you protect something you don’t understand? Imagine being
hired to secure a building without knowing how the doors lock, how the windows
open, or how the alarm system works. You might install cameras and motion
sensors, but you wouldn’t know if the doors were sturdy enough to withstand
forced entry or if the windows could be easily bypassed.
In IT, the situation is similar. You cannot secure a network
if you don’t understand how IP addresses and routing work. You cannot harden an
operating system if you don’t know how file permissions and processes are
managed. You cannot identify a phishing attack if you don’t understand how
email protocols work. Cybersecurity requires both defensive thinking and
technical fluency—skills that are built by first learning the building blocks
of IT.
A strong foundation not only helps professionals understand
how systems work, but it also enables them to troubleshoot problems more
effectively, adapt to new technologies, and anticipate where vulnerabilities
might exist. Cybersecurity is not just about responding to threats; it is about
understanding the environment well enough to predict and prevent them.
The
Fundamentals Every Aspiring Cybersecurity Professional Must Master
Before pursuing cybersecurity certifications, students
should focus on building a solid foundation in the following areas:
1. Operating Systems
Understanding operating systems is crucial because they form
the backbone of every IT environment. This includes learning how Windows,
Linux, and macOS manage processes, memory, file systems, and user
permissions. For example:
- How
does Windows Active Directory manage user authentication?
- How
does Linux handle file permissions and security policies?
- What
are the differences in system architecture across platforms?
Without this knowledge, security topics like privilege
escalation, patch management, or malware analysis will be difficult to grasp.
2. Computer Hardware and Peripherals
Cybersecurity may focus on software and data, but hardware
still matters. Knowing how CPUs, memory, storage devices, and peripherals
interact helps professionals understand attack vectors such as firmware
vulnerabilities, USB exploits, or side-channel attacks. Even understanding
basic troubleshooting of hardware builds confidence in working with complex
systems.
3. Networking Fundamentals
Networking is perhaps the single most important area of
knowledge for aspiring cybersecurity professionals. Cybersecurity threats often
exploit the way data moves across networks. Students must learn:
- The
OSI and TCP/IP models
- IP
addressing, subnetting, and routing
- Common
protocols such as DNS, HTTP/S, FTP, and SMTP
- The
difference between switches, routers, and firewalls
- How
packets flow across a network and what tools (like Wireshark) reveal about
traffic
If you don’t understand how normal traffic flows, you cannot
detect abnormal traffic or malicious activity.
4. Risk Management Basics
Cybersecurity is not just technical—it’s also about business
and risk. Professionals must understand how to identify, assess, and mitigate
risks in an organization. This includes concepts such as:
- Threats,
vulnerabilities, and exploits
- Risk
likelihood and impact
- Risk
mitigation strategies (avoidance, acceptance, transfer, reduction)
- The
role of compliance and regulations
Risk management bridges the gap between technical security
controls and organizational decision-making.
5. The CIA Triad
At the heart of cybersecurity is the Confidentiality,
Integrity, and Availability (CIA) Triad. These three principles are the
foundation for all security decisions:
- Confidentiality
ensures that data is accessible only to authorized individuals.
- Integrity
ensures that data remains accurate and unaltered.
- Availability
ensures that systems and data are accessible when needed.
Nearly every cybersecurity control—whether it’s encryption,
backups, or access management—exists to support one or more of these
principles.
The
Problem with Skipping Fundamentals
When students skip straight to cybersecurity, they face
several challenges:
- Overwhelm
and Burnout: The sheer amount of unfamiliar terminology and concepts
leads to frustration.
- Shallow
Knowledge: Without context, students may memorize facts but fail to
apply them in real-world scenarios.
- Limited
Career Options: Many entry-level IT jobs (like help desk, system
administration, or networking support) provide the experience needed to
grow into cybersecurity. Skipping them means missing out on valuable
stepping stones.
- Employers’
Expectations: Organizations expect cybersecurity professionals to
already understand IT basics. Lacking these makes candidates less
competitive in the job market.
The result is a cycle where students spend time and money on
certifications but struggle to secure jobs, leaving them disillusioned.
Building
the Right Path Into Cybersecurity
So, if cybersecurity is not entry-level, what is the right
path? Here’s a suggested progression:
- Start
with IT Fundamentals
- Learn
basic computer hardware, operating systems, and networking.
- Entry-level
certifications like CompTIA A+ and CompTIA Network+ are
great stepping stones.
- Gain
Practical IT Experience
- Work
in roles like IT support, help desk, or junior system administrator.
- Use
labs and virtual machines to experiment with systems.
- Learn
Cybersecurity Basics
- Once
you are comfortable with IT, move to CompTIA Security+ or similar
foundational cybersecurity certifications.
- Build
familiarity with firewalls, SIEMs, vulnerability management, and incident
response.
- Specialize
in Cybersecurity
- Pursue
advanced certifications like CEH, CySA+, CISSP, or OSCP depending on your
career goals.
- Explore
areas like penetration testing, cloud security, or digital forensics.
This staged approach ensures that you not only learn
cybersecurity but also develop the broader IT skills that employers look for.
How
Tutoring Helps Students Succeed
For students struggling to build these foundations,
self-study can feel overwhelming. That’s where guided tutoring can make a
difference. With personalized support, students can learn at their own pace,
ask questions in real time, and receive explanations tailored to their learning
style.
As an experienced IT and cybersecurity professional with
decades of real-world and teaching experience, I work with students to break
down complex topics into understandable lessons. Whether you are struggling
with subnetting, Windows file permissions, or the CIA triad, tutoring sessions
provide clarity and confidence.
Through platforms like Preply and Wyzant,
I help students prepare for IT fundamentals and cybersecurity certifications in
a structured, step-by-step way. Many students who felt lost in bootcamps have
found success when given the chance to build their knowledge from the ground
up.
Wrapping It All Up
Cybersecurity is an exciting, rewarding, and essential
field—but it is not an entry-level starting point in IT. Certifications like
CEH may be labeled as “entry-level” within the domain, but they still require a
working knowledge of IT fundamentals. Skipping those fundamentals leaves
students overwhelmed, frustrated, and at a disadvantage in the job market.
The key to success is to start with the basics: operating
systems, networking, hardware, risk management, and the CIA triad. With these
in place, students can confidently progress into cybersecurity and make sense
of its tools, strategies, and challenges. Employers value candidates who
understand not only how to defend systems but also how those systems work.
For students who need extra help mastering these essentials,
tutoring can provide the personalized guidance that bootcamps often lack. By
building knowledge step by step, students transform confusion into confidence
and set themselves up for long-term career success.
Cybersecurity isn’t off-limits for beginners—it just
requires the right foundation. Start with the fundamentals, and you’ll be
prepared to climb as high as you want in this dynamic and ever-growing field.
