Today, a cybersecurity career is highly promising. This article will give you an insight into the most important cybersecurity skills and the role it plays in a cybersecurity professional's career. So, let's begin!

With businesses moving online and shifting to cloud storage. Currently, the demand for cybersecurity is at its peak with that comes a high demand for cybersecurity experts who can safeguard digital data.

On that note hey guys welcome to yet another exciting article in this article I bring you the top five cybersecurity skills in 2021 So let's get started!

According to cybercrime magazine by cybersecurity ventures globally there would be nearly 3.5 million unfilled cybersecurity jobs by 2021 and the number of internet users will hit a whopping 6 billion by 2022. 

These numbers speak volumes and this shows the growing demand for cybersecurity professionals across the globe. Now that you know the high demand for cybersecurity professionals let us help you start your cybersecurity career by bagging the top 5 right cybersecurity skillset.

Many of you out there might be waiting to become a cybersecurity professional but are unsure of how to go about it and what skills you would need to get a cybersecurity job. 


The number one skill you need to have to enter the field of cybersecurity is COMPUTER NETWORKING - Networking is the backbone of the internet you must have an in-depth understanding of networking to start a career in cybersecurity.

A network is a group of interconnected devices and networking is the art of understanding how data is sent, transmitted, and received amongst these devices. You need to know various routing protocols the TCP/IP and OSI models govern networking.

The OSI model is comparatively newer basically in these models all the protocols are grouped into layers and work together to help you receive data on your device sent from a server. Learning networking will help you understand the technical aspects of data transmission which will help you secure your data. 

You can take up networking certifications like security plus and cisco CCNA to gain a strong networking foundation.

Another skill that will be beneficial for you is TO MASTER SYSTEM ADMINISTRATION - If you think about it all of us are cis admins at some level. 

System Administration - It is all about configuring and maintaining computers you must be curious to know every aspect of your computer features and settings and play around a bit. 

Carry out a trial and error method and give yourself small tasks like recovering deleted files or monitoring old viruses on a VM, explore new techniques put them into use, and expand your knowledge.


To become a cybersecurity professional you need to have a strong knowledge of operating environments such as windows, Linux, and Mac OS.

Cybersecurity professionals largely use Linux and it comes with several tools. To learn operating systems go ahead and set up and use virtual machines that are VMS and play around with them this will help you gain hands-on experience. As a cybersecurity expert, you should be comfortable working on any OS.

VMS allows you to train and research in an isolated environment and help you maximize your skills.

The next point to remember is to know KALI LINUX is the most widely known Linux distribution for ethical hacking and penetration testing. It comes with several hundred tools related to penetration testing, malware analysis, security research, computer forensics, and so on.

Kali contains several projects and you can learn a lot another good thing about kale is that it is free to use so what are you waiting for download and start right away. Remember that Linux is the backbone of cybersecurity and a commonly asked topic for cybersecurity interviews especially for pen testing roles.


It is another basic skill that every cybersecurity professional should have. Network security control refers to the different measures which are employed to enhance the security of a network. It is simple you can only safeguard your network if you know how it works, how routers firewalls, and other devices work.

A firewall is a hardware or software that blocks incoming or outgoing traffic from the internet to your computer. Firewalls are required to secure a network as a cybersecurity expert you must be able to leverage a firewall to filter and prevent unauthorized traffic onto the network. 

In addition to that as a cybersecurity expert, you must know about intrusion detection systems, intrusion prevention systems, virtual private networks, and remote access.

An intrusion detection system IDS is designed to detect unauthorized access to a system. It is used together with a firewall and a router you should be able to operate the IDS and recognize any security policy violations and malicious traffic on the network. 

As many of you may have used a VPN is a connection between a VPN server and a VPN client is a secure tunnel across the internet.


So you might be wondering if coding is really required to become a cybersecurity professional well it is true that not all cybersecurity professionals have or need coding skills however having zero coding knowledge may limit your opportunities in the future.

Knowing a couple of programming languages will help you identify the plan behind an attack and defend against deadly hacking techniques. We have C and C++. 

The C programming language is the backbone of most operating systems C and C ++ are low-level programming languages that you need to know as a cybersecurity professional.

On the other hand, PYTHON is a high-level programming language that is becoming popular among cybersecurity experts today knowing python will give you an upper hand in your career. It will help you identify and fix vulnerabilities 

JAVASCRIPT is another high-level programming language that adds interactivity to web pages. A good advantage of knowing javascript is that you can prevent cross-site scripting attacks from occurring. As in these attacks, the attacker implants malicious code in a web application.

Speaking of PHP because most of the websites are created using PHP learning it will help you defend against intruders. 

Similarly, HTML is another language cybersecurity professionals should understand as most websites use it and it is one of the easiest languages to learn.

Another programming language that you can use is GOLANG it is great for Cryptography you can solve various cybersecurity problems with it.

Then we have SQL that is a structured query language. Attackers use this language to damage the stored data.

One such example is the SQL injection attack hence having a good understanding of SQL will be highly beneficial.

Another point I'd like to highlight is to have knowledge of assembly language this will help you become a cybersecurity engineer assembly will help you understand how malware functions and thereby help you defend against it.

In the cybersecurity domain, you can't just lock into a single language and hence it is advised that you're acquainted with a couple of them. You can also do a crash course for these languages and learn them. Hence determine the best programming language for your cybersecurity role and get familiar with the basics.
