How to become a cybersecurity expert

The demand for cybersecurity experts has never been higher. As cyber threats continue to evolve, organizations of all sizes are seeking skilled professionals to protect their sensitive data and systems. Becoming a cybersecurity expert requires a strong foundation in IT and networking, proficiency in security tools, and a deep understanding of cyber threats and weaknesses. In addition to technical skills, staying updated with the latest industry trends, certifications, and hands-on experience is crucial to mastering the field and excelling in a cybersecurity career.

What is Cybersecurity?

Cybersecurity protects systems, networks, and data from digital attacks, unauthorised access, and damage. It involves the use of technologies, processes, and controls to safeguard sensitive information, ensure the confidentiality, integrity, and availability of data, and prevent cyber threats such as hacking, malware, ransomware, and phishing. Cybersecurity spans various domains, including information security, network security, application security, and operational security, and is essential for both organizations and individuals to defend against evolving cyber risks.

The growing demand for cybersecurity experts is based on the increasing frequency and competence of cyberattacks, as well as the expanding digital world. With more organizations and industries moving online, the risk of data violations, ransomware attacks, and other cyber threats has surged. This has created a pressing need for skilled professionals who can protect sensitive information, secure networks, and ensure compliance with regulatory requirements.

Key factors contributing to the growing demand include:

1. Rise in Cybercrime: Cyberattacks are becoming more complex, targeting critical infrastructure, financial systems, and personal data.

2. Digital Transformation: As businesses adopt cloud computing, IoT devices, and remote work models, the attack surface expands, necessitating strong cybersecurity measures.

3. Regulatory Compliance: Governments are enacting stricter data protection laws, such as GDPR and CCPA, requiring organizations to enhance their cybersecurity practices.

4. Shortage of Talent: The cybersecurity workforce gap means there aren’t enough qualified professionals to fill the growing number of job openings.

This demand spans across sectors like finance, healthcare, government, and tech, offering lucrative career opportunities for those pursuing cybersecurity training and certifications.

Build a Strong Foundation in IT and Networking

To succeed in cybersecurity, building a strong foundation in IT and networking is essential. Here are the key steps:

1. Understand Basic IT Concepts: Grasp the fundamentals of computer systems, including hardware, software, and data storage. Knowing how systems operate will help you understand how to secure them.

2. Learn Networking Protocols: Networking is the backbone of communication in the digital world. Learn about key protocols such as TCP/IP, DNS, HTTP, and more, which will help you detect and prevent network-based attacks.

3. Familiarize Yourself with Operating Systems: Understanding the inner workings of operating systems like Windows, Linux, and macOS is crucial. Each system has unique vulnerabilities that you’ll need to secure.

4. Master Firewalls and Routers: These are the first lines of defense in a network. Learn how firewalls block unwanted traffic and how routers facilitate secure communication between networks.

These skills will provide the technical knowledge needed to start solving real-world cybersecurity challenges.
