Networking and system administration

At the heart of cybersecurity lies an intricate understanding of networking. To effectively secure data, you must grasp the technical intricacies of data transmission. Earning certifications like CompTIA Security+ and Cisco CCNA is a solid starting point. System administration is equally crucial. It involves configuring and maintaining computer systems, demanding an inquisitive mindset for exploring various computer features and settings. Networking and system administration are the foundational pillars of cybersecurity, allowing you to understand data flows, system vulnerabilities, and potential entry points for malicious actors.

Top 8 Cybersecurity Skills You Must Have

Knowledge of operating systems and virtual machines

A cybersecurity professional’s proficiency should encompass operating systems like Windows, Linux, and Mac OS. Versatility across multiple OSs is essential, as the digital landscape comprises a diverse range of environments. Moreover, familiarity with Kali Linux, a Linux distribution renowned for ethical hacking and penetration testing, is invaluable. It boasts an arsenal of tools for Penetration Testing, Malware Analysis, Security Research, and more. Operating systems are the battlegrounds where cybersecurity experts defend against threats and vulnerabilities, making mastery of these environments essential.

Network security control

Network Security Control comprises various measures to bolster network security. Understanding how your network functions, the roles of routers, firewalls, and other devices is fundamental. Firewalls, both hardware and software, serve as gatekeepers to block unauthorized traffic from the internet. Cybersecurity experts employ firewalls to filter and prevent illicit network access. Proficiency in Intrusion Detection Systems (IDS), Intrusion Prevention Systems, Virtual Private Networks (VPNs), and remote access is essential. As a cybersecurity practitioner, you must operate IDS to identify security policy violations and malicious network traffic. These tools are the guardians of the digital kingdom, safeguarding against unauthorized access and malicious activity.

Cybersecurity professionals should acquaint themselves with coding languages. This knowledge is pivotal to addressing future cybersecurity challenges. Coding languages to explore include:

  • C and C++: Low-level programming languages vital for cybersecurity, allowing you to dissect and understand the inner workings of software and systems.
  • Python: A high-level language useful for identifying and resolving vulnerabilities through scripting and automation.
  • JavaScript: Ideal for countering cross-site scripting attacks, making the web safer for users.
  • PHP: A crucial skill for safeguarding websites, as it is a commonly targeted language by cybercriminals.
  • HTML: Fundamental for understanding web page structures and identifying potential vulnerabilities in web applications.
  • Go lang: Valuable for cryptography, a cornerstone of secure communication in the digital realm.
  • SQL: Vital for recognizing and mitigating SQL injection attacks, a common technique used by attackers.

Assembly Language: Essential for comprehending malware functionality, aiding in malware analysis and reverse engineering. Coding languages are the tools in a cybersecurity expert’s arsenal, allowing them to analyze, detect, and mitigate threats.

Cloud security

As organizations increasingly adopt public and hybrid cloud platforms such as AWS and Azure, professionals with cloud security skills are in high demand. Just like Application Development Security, Cloud Security emphasizes building secure systems from the outset, making professionals proficient in managing platforms like Microsoft Azure, AWS, and Google Cloud highly sought after. Cloud security is not just about securing data in the cloud but also configuring cloud environments, enforcing access controls, and ensuring data integrity, making it a critical skill in the digital age.

Blockchain security

The rise of blockchain technology underscores its significance in enhancing security. Cybersecurity experts must acquaint themselves with blockchain’s security aspects. It holds the potential to transform security in areas like Internet of Things devices, network control, supply chain integration, identity management, and mobile computing. Blockchain’s complex, decentralized nature makes it an ideal solution for securing critical data in a digital world rife with cyber threats. Understanding how to implement and maintain blockchain security is essential for future-proofing the digital landscape.

The Internet of Things (IoT)

With over 30 billion IoT devices projected to be connected globally by 2025, security vulnerabilities multiply. IoT security takes center stage, emphasizing the need to protect connected devices and networks, even those with minimal human intervention. The complexity of IoT ecosystems requires cybersecurity professionals to secure these devices, data transmissions, and networks. IoT security emphasizes protecting connected devices and networks over the Internet, especially since most of these devices access networks without human intervention or oversight. Therefore, it becomes important to make sure that proper security measures are in place so that IoT devices can be left alone to perform their functions automatically, without cybersecurity experts having to be concerned about keeping out unauthorized intruders.

Artificial Intelligence (AI)

Artificial Intelligence emerges as a game-changer in cybersecurity. It introduces automation, enabling cybersecurity professionals to identify and respond to threats more effectively. AI can evolve to handle emerging threats and hacking techniques, significantly bolstering cybersecurity measures. AI brings a level of automation and support that is unmatched by human capabilities, catching threats that may otherwise go unnoticed and unaddressed. Artificial Intelligence can also be trained to learn and evolve, making it better equipped to handle new emerging threats and hacking techniques. This makes AI a valuable ally in the ongoing battle against cyber threats.

Additional cybersecurity skills

In addition to the primary skills mentioned above, consider these supplementary skills to strengthen your cybersecurity prowess:

Risk Analysis

Identifying, managing, and mitigating risks is pivotal. Cybersecurity professionals are required to identify, manage, and mitigate risks, making them invaluable assets to organizations looking to protect their digital assets.

Information security

Protecting electronic data from unauthorized access is a foundational skill. Companies require skilled professionals who can protect their electronic data from unauthorized access.

Security incident handling & response

Preparing to handle security threats in real-time is an essential skill for any cybersecurity expert. With security incident management, you are required to identify, manage, record, and analyze security threats in real-time. As a security practitioner, you must also manage and analyze the security information and event management (SIEM) tools and services. Handling security incidents effectively is essential for minimizing damage and maintaining the integrity of an organization’s security.

Security audit

It is an internal check that is carried out to find flaws in the organization’s information system. Security audit and compliance knowledge are very crucial because any missed area of regulatory compliance might incur significant fines and penalties for the organization. Conducting security audits is essential for ensuring that an organization’s security measures are effective and compliant with relevant laws and regulations.

Laws and regulations

This is an often overlooked cybersecurity aspect. There are several cybersecurity laws and regulations that you should be aware of. These laws define how you can use the internet and protect people from becoming victims of cybercrimes. Understanding the legal and regulatory aspects of cybersecurity is essential for ensuring that an organization’s practices are in compliance with the law and that individuals’ rights are protected.


Cybersecurity is an ever-evolving field. Staying current with new hacks and tools is essential. Moreover, soft skills play a crucial role in advancing your career in cybersecurity.
