Cybersecurity is one of the few niches where simply reading books is not enough. You may know a lot about encryption, firewalls, vulnerabilities, but without applying practical tools, it will not be easy to succeed.
But there is one problem.
Cybersecurity includes hundreds of tools dedicated to specific tasks:
Scanning networks
Packets analysis
Vulnerability scanning
Exploitation
Password cracking
Monitoring, detection, etc.
For beginners, it is hard to cope with them all.
The good news is that you should focus only on a few tools, which will give you 80% of needed skills.
In this guide, we will discuss several categories of cybersecurity tools and provide examples of how to use them.
For each tool, I will describe:
What it does
Why it matters
How to apply it
Example
Skills
1. Network Scanning Tools
Nmap
What is it?
One of the basic and most popular tools, which allows scanning networks and discovering available devices and services.
Questions that you may answer while scanning:
“What is running and accessible?”
Capabilities
- Discover active hosts
- Find out open ports
- Identify available services (HTTP, FTP, SSH, etc.)
- Detecting OS
- Identifying possible vulnerabilities
Why it matters
All cybersecurity procedures start with reconnaissance.
You need to discover what you can work with and what needs to be attacked or protected.
Why it is important? Because you will not be able to hack something if you have no idea about it.
And Nmap is widely used during penetration testing.
Example for beginners
nmap -sV 192.168.1.1Explanation
-sV→ Discovering service versions- Scanning the specific IP address
- Showing open ports and available services
Results
PORT STATE SERVICE VERSION
80/tcp open http Apache 2.4.41
22/tcp open ssh OpenSSH 7.6What you can learn
- Network ports and protocols
- Structure
- Available services
- Service version enumeration
Shodan
What is it?
Search engine that shows connected devices on the internet.
So instead of manually scanning networks, you will be able to analyze available systems on the internet.
Available systems include:
- Cameras
- IoT
- Servers
- Database
- Industrial systems, etc.
Why it is powerful?
You will get to know the main idea:
Not only people, but various systems are available via the internet — and a huge number of them are vulnerable.
Example
First search:
apacheYou will get information about many servers with apache.
Advanced search:
apache country:"US" port:80What you can learn
- Exposure risks
- Misconfiguration
- Internet attack surface
2. Packets Analyzers

Why it matters
Security is inseparably connected with working with data and its flow through systems.
Wireshark will help you to understand:
- What is normal traffic
- What is abnormal traffic
- What could be considered malicious traffic
Example
Start Wireshark → select an appropriate interface → capture traffic → apply filter:
httpResult
You will see only HTTP traffic
Practical example
- Analysis of DNS queries → check which websites were opened by a user
- Identifying unsecured traffic
- Detection of strange activity
What you will learn
