Cybersecurity vs Computer Science [Which is Better?]

Cybersecurity and computer science are both complex fields that require a strong technical background and expertise in various areas of computing. Both of them have different curricula so it is not possible to decide which one is harder. Both courses require a high level of technical expertise, continuous learning, and problem-solving skills.

Cybersecurity is said to be challenging as it evolves cyber threats and has new technologies that can detect everything easily.

Overall, both are important fields in the world of technology, but they have different areas of focus, goals, areas of expertise, and tools and techniques.

Key Differences Simplified

Computer science: It involves the study of algorithms, programming languages, data structures, computer architecture, software engineering, and other related topics. It requires a strong foundation in mathematics, logic, and problem-solving skills. Computer scientists work on developing software and hardware systems, designing algorithms, and analyzing data.

Cybersecurity:  It involves protecting computer systems, networks, and data from cyber threats such as malware, phishing attacks, and hacking attempts. Specialists in the field of cybersecurity need to be extremely knowledgeable about network standards, cryptography, password protection, and regulatory compliance.

They also need to be capable of thinking like attackers to find weaknesses in information systems and create countermeasures. Defending those networks from attacks is the main goal of security.


Computer science and cybersecurity are both important fields in the world of technology, and both have a high demand for skilled professionals. The BLS also states that in May 2020, the average yearly pay for jobs in the computing and communication technology sector was $91,250, which is more than the average yearly pay for all sectors.

Information security analysts’ employment is expected to increase by 31% between 2019 and 2029, according to the BLS, which is substantially greater than the typical increase for all occupations. Security analysts who work with the information made an average yearly salary of $103,590 in May 2020, which was greater than the average for all occupations.

Is it compulsory to do a CS degree in cyber security? 

Many professionals in this field come from diverse educational backgrounds such as information technology, mathematics, engineering, or even non-technical fields. Overall, while a CS degree can be helpful, it is not a strict requirement for a career in cyber-security.

What are some emerging trends in these courses?

Some of the emerging trends in these courses are Artificial Intelligence (AI) and Machine Learning, Blockchain, Internet of Things (IoT), Cloud Computing, Quantum Computing, Privacy and Data Protection, and Regulations.

How does computer science contribute to the field of cybersecurity?

Computer science is a crucial part of Cybersecurity. Professionals need a strong foundation in cs to develop effective solutions that can protect against increasingly sophisticated cyber threats.

CS contributes to this field in various ways such as developing secure software, designing secure networks, analyzing cyber threats, developing cryptography, and developing Artificial Intelligence and Machine Learning Solutions.

How long does it take to earn a degree in both fields?

The time it takes to earn a degree in both fields depends on several factors, including the level of degree, the student’s course load, and whether they attend school full-time or part-time.

  • A bachelor’s degree in both fields typically takes four years to complete, although some accelerated programs or online programs may take less time.
  • A master’s degree in both fields typically takes one to two years to complete, depending on whether the student attends full-time or part-time.
  • A doctoral degree in both fields typically takes three to five years to complete, although the exact time may vary depending on the student’s research and dissertation requirements.

What are some certifications that are useful for these courses?

The certifications that are useful for both professionals are as follows:

  • CompTIA A+ Certification
  • CompTIA Network+ Certification
  • Certified Information Systems Security Professional (CISSP)
  • Certified Ethical Hacker (CEH)
  • Offensive Security Certified Professional (OSCP)

What kind of companies and industries hire both professionals?

Across a wide range of industries, computer science, and cybersecurity professionals are in demand. The professionals are hired by the following companies and industries:

  • Technology Companies
  • Financial Services
  • Government Agencies
  • Healthcare
  • Retail and E-commerce
  • Consulting Firms
