What are the Differences Between Cybersecurity and Data Science?


We continue to produce increasing amounts of data every day as technology advances and digitization expands. This is where cyber security and data science come into play.

These two powerful sectors, which today dominate the digital economy, are required for evaluating data sets and safeguarding the information extracted.

The difference between data science and cyber security can be examined in numerous aspects such as job roles, career pathways, and courses involved.  We'll look at a few of them in this article to help you find the perfect career.

Both the fields of cyber security and data science are tough and competitive fields. As a result, it is critical for applicants to have a thorough understanding of these areas. Both Cyber Security and Data Science require the ability to communicate effectively using figures and data. In comparison to data science, which was named the sexiest job of the twenty-first century by a Harvard Business Review article in 2012, cyber security has limited career options.

Cyber Security Explained

Cyber security is a field that encompasses technology, strategies, and processes for securing systems, networks, devices, and data against cyber security threats and cyber attacks, and illegal access. A person who specializes in this field is referred to as a cyber security analyst or specialist. The domain of cyber security has seen a threefold expansion in the last few due to the growing volume and intensity of cyber attacks and cyber threats, and this trend is projected to continue.

What does a Cyber Security Analyst Do?

A Cyber Security Analyst is in charge of ensuring that a company's computer and networking systems are secure and effective. Cyber security specialists must continually look for flaws in the company's technology and software to guarantee that no one has unauthorized access to data. The following are some of their additional responsibilities:

  • Firewalls are being added to networking systems.

  • Identifying access permissions.

  • securing the information technology infrastructure

  • Cyberattacks are being monitored on the network.

  • Detecting and removing potential risks or breaches.

  • Detecting cyber-assailants.

  • Security policies are being communicated to the company's employees.

Numerous institutes cater to the need for training expert cyber security analysts through intensive cyber security course programs and training.  Typically a cyber security course will teach you from the ground up about ethical hacking, cryptography, computer networks and security, application security, management of identity and access, malware threats, vulnerability analysis, sniffing, DoS, session hijacking, SQL injection, and other security practices for businesses. To become a cyber security analyst one has to go through all these necessary training to upskill oneself and to be competent in their jobs. It is ideal for aspirants to enroll in a cyber security certification training program to learn from industry experts, work on real-world projects, and receive their certification, which is also a mandatory credential.

Data Science Explained

The study of vast and complicated data sets in order to develop analytical models for uncovering insights and unlocking value-driven business decisions is known as data science. Artificial Intelligence, Machine learning, statistics, databases, modeling, and programming are all core elements of data science. 

A data scientist is an expert who specializes in obtaining raw data, transforming it into an analysis-ready format, and then feeding it into algorithms and models to derive actionable insights are all the constituents parts of the data science process.

What does A Data Scientist Do?

Data scientists are in charge of gathering vast amounts of data, processing it, and interpreting it for commercial objectives. They use the information gleaned from data to help the organization solve problems and make decisions. In addition to the responsibilities listed above, data scientists are responsible for:

  • Processes for data modeling design.

  • Creating algorithms for machine learning.

  • Database creation and maintenance.

  • Assessing the data's quality.

  • Unstructured data is being cleaned up.

  • Reports for executive and project teams are being prepared.

  • Making recommendations to the executive team.

  • To show information, data visualizations are created.

  • Collaboration with other groups.

  • Ensemble modeling to combine models

To become a data scientist one must be proficient and must have s strong Mathematical and Statistical basis. A data science course typically fulfill all the requirements in term of providing skills, knowledge, and expertise. Data science course programs are elaborately formulated t provide professionals with the familiarity with Python and R programming and the capability to use them for data mining, manipulation, calculation, graphical display, and the operation of embedded systems. Statistical modeling software, such as SQL databases and the Hadoop platform, are also required skills for data scientists.

Aside from the technical abilities described above, communication, problem-solving, critical thinking, and cooperation skills are all required soft skills for data scientist jobs.

The distinction between Cyber Security Analyst and Data Scientist

We have learned that Cyber security and Data science although dealing with the advancements ushered in by the technological revolution, both follow a different trajectory in terms of their tasks and career prospects. While Cyber security experts are responsible for safeguarding data and networks, as well as monitoring security infrastructure and auditing regulations. Data scientists' responsibilities on the contrary include data analysis, model creation, predictive analytics, and machine learning, among other things.

To be a cyber security analyst, you'll need a degree in computer engineering, information security, or computer science, as well as appropriate certifications like CISA, CISSP, CEH, and others. Unlike cyber security, data science demands a significantly higher level of education. To have a successful career in data science, an aspirant must have both a bachelor's and a master's degree in the field.

Network engineer, cyber security analyst, systems engineer, cryptographer, and more cyber security job titles exist. Data scientists, data analysts, machine learning engineers, data architects, and data engineers are just a few of the job titles in data science.
