Let’s go!

What is Cyber security?

Cyber security is the safeguarding of files, data, computers, servers, and networks from malicious attacks. These cyberattacks aim to gain unauthorized access, alter, steal, or destroy sensitive data. Individuals and businesses use cybersecurity to protect their data and files from such cyber attacks. A cybersecurity expert employs technologies and methodologies to protect devices and networks. It includes aspects like network security, application security, data security, identity management, mobile security, disaster recovery, and penetration testing. The duties of a cybersecurity expert include ensuring the safety of digital assets and preventing cybercrime.

Why you should learn cyber security?

Cyber security is a valuable skill that comes with several benefits. Here are some of the most important benefits of learning cybersecurity:

  1. Protecting Personal Data: With the increasing reliance on digital platforms, personal data is vulnerable to cyber threats. Cybersecurity empowers individuals and businesses to safeguard their information from unauthorized access and potential theft.
  2. Career Opportunities: Cybersecurity as a service is in high demand, offering lucrative job opportunities. As cyber threats evolve, the need for skilled cybersecurity professionals is expected to continue growing.
  3. Advancing Technological Expertise: Cybersecurity involves mastering various technologies and methodologies. Learning cybersecurity enhances your technical skills, enabling you to stay up-to-date with the latest tech advancements.

Is cyber security hard to learn or practice?

Learning cybersecurity is not difficult, but certain aspects may pose challenges, especially for beginners. For example, coding can be challenging if you’re new to programming. The complexity of cybersecurity can vary depending on the specific area you focus on and your prior technical knowledge. Understanding cybersecurity concepts, networking, and coding requires time and effort. However, with proper guidance, training, and practical experience, it becomes more manageable. As you gain expertise and work on projects, you will build confidence and improve your skills. The dynamic nature of cybersecurity also means that you need to stay updated with the latest threats and defense techniques.

Requirements of a Cybersecurity Expert

Typically, a bachelor’s degree in Computer Science or equivalent education or work experience is preferred for aspiring cybersecurity experts. Additional, essential soft skills like communication, leadership, teamwork, and problem-solving abilities, are necessities for a cybersecurity expert to excel. The following skills are crucial for any aspiring cybersecurity specialist:

1. Networking and System Administration

A comprehensive understanding of computer networking is essential for a successful career in cybersecurity. Knowledge of data transmission and communication for connected devices within a network is fundamental.

2. Operating Systems and Virtual Machines

To thrive in cybersecurity, you must have in-depth knowledge of operating systems like Windows, Linux, and Mac OS. The ability to use different OS environments is essential. Practical experience with virtual machines (VMs) allows for safe experimentation and learning about operating systems.

3. Network Security Control

Expertise in network security control methods is crucial for identifying, enhancing, and maintaining the confidentiality of network assets. Understanding how routers, firewalls, and other security devices operate is vital for protecting networks. Familiarity with virtual private networks (VPNs), remote access, intrusion detection systems (IDS), and intrusion prevention systems (IPS) is essential.

4. Coding Skills

While not every cybersecurity professional needs to be a coding expert, possessing basic coding knowledge is valuable. Familiarity with relevant programming languages enables specialists to identify attack strategies and develop effective defenses.

5. Cloud Security

The demand for cybersecurity experts with cloud security expertise is on the rise, especially with public and hybrid cloud platforms like Amazon Web Services. Understanding how to implement security policies for cloud-based systems is crucial in the modern cybersecurity landscape.

Roles of a Cyber Security Expert

The roles of cybersecurity professionals vary depending on the specific position and organization they work for. Some common responsibilities of a cybersecurity specialist include:

  1. Implementing security measures for software systems, networks, and data centers during development.
  2. Safeguarding protected information and assets from unauthorized access.
  3. Evaluating and identifying vulnerabilities and risks in hardware and software.
  4. Designing and implementing effective strategies to secure IT infrastructure.
  5. Conducting testing of security strategies and defenses.
  6. Integrating firewalls into system and network infrastructures.
  7. Monitoring systems for intrusions and cyber attacks.
  8. Providing training to colleagues on security protocols and best practices.
  9. Preparing reports to keep stakeholders informed of security activities.
  10. Identifying and securing potential vulnerabilities.
  11. Responding to and mitigating attacks or intrusions.
  12. Analyzing new methods utilized by cybercriminals.
  13. Staying updated on new trends and procedures to prevent attacks.
  14. Adjusting security measures to address ongoing changes and needs.

How long does it take to be a Cyber Security Expert?

Becoming a cybersecurity expert requires time and dedication to understand the concepts and skills involved. Unlike some tech careers, achieving expertise in cyber security usually takes about a year or two, and it cannot be accomplished in a mere three months. The timeline varies based on your educational path and your prior technical knowledge.

If you opt for a traditional college education, obtaining a bachelor’s degree in cyber security would typically take four to five years, while pursuing a master’s degree would require an additional two years of study. Alternatively, enrolling in a cyber security coding boot camp could take anywhere from six months to a year to complete, offering a more condensed and focused learning experience.

Frequently Asked Questions

Can I teach myself cyber security?

Yes, like some other tech skills, self-learning cybersecurity is possible. However, it requires dedication, access to resources, and consistent practice.

Can I learn cyber security in 3 months?

Learning cyber security to a proficient level in just 3 months is highly unlikely. It typically requires more time and ongoing learning.

Is cybersecurity a lot of math?

While some aspects of cybersecurity involve math, it is not a predominant requirement for all cybersecurity roles. Basic math skills are generally sufficient for most areas.


Cybersecurity can be challenging to learn and practice, especially for beginners. However, with determination, access to resources, and consistent practice, you can develop proficiency in cyber security. The growing demand for skilled cybersecurity professionals further emphasizes the significance of the industry, making it a promising career path.
