Cyber security vs Data Science

Data Science doesn’t restrict to one job as it involves multiple disciplines such as extracting data, collecting it, building data models, performing analysis, and finally communicating the findings for business solutions. Cyber Security focuses completely on data security. It guards data systems and networks from unauthorized access, breaches, and cyber-attacks. It requires continuous data monitoring, scanning, detecting risks, and updating the system for protection. There is a lot of discussion about which is a better career choice in Cyber Security vs Data Science, but the two jobs are very different in disciplines and responsibility. It is important to understand the two fields thoroughly to make a decision.

In this article we will discuss the basic concepts of Cyber Security and Data Science while explaining the objectives, importance, skills sets, career paths, job roles and responsibilities, job positions, and educational requirements in the two fields.

Difference between Data Science and Cyber Security

The main difference between Cyber Security and Data Science is that Data Science works on the data while Cyber security protects the data. Data Science manipulates big data with scientific approaches to use in business. Whilst Cyber Security safeguards the big data pools in a business from threats.

What is Data Science?

In an organization, Data Science is responsible for working on big data sources to get insights for decision making. It requires knowledge of the organization, programming skills, scientific methods, tools, and techniques to get the end results. Data Science professionals must possess fluency in machine learning and deep learning. One of the uses of Data Science can be understood by example of corporates where Data Science extracts current and future trends to help businesses make informed decisions.

How does Data Science work?

Data Science has a lifecycle of 5 stages, which are

  1. Acquiring data- Collection of structured and unstructured data in different forms and patterns, understanding the obtained data, database management, and storage.
  2. Cleaning the data- Cleaning and processing data for readability and error-free analysis.
  3. Analyzing data- Data visualization to find patterns and trends and to build hypotheses.
  4. Modeling the data- Writing algorithms for predictive solutions on the data resulting in error-free insights.
  5. Communicating the data- Using different visualisations or presentation skills to present the findings.

Career in data science

As the data available is increasing, so increases the demand for Data Science professionals. All major businesses and organizations use data science to increase customer satisfaction, product quality, service improvement, and business expansion. To begin with, you can start with a data science graduation or diploma. But even if you are graduated in any other field, there are many data science certification courses available that can help you learn all the industry-based skills and tools to start your career

Anexas Data Science Course is conducted in three levels basic, intermediate and advanced. The course contents include the basics of data science, all programming tools, and concepts like modeling analyzing, and visualizing data. After completion, you are certified by Anexas Europe Certification. You may choose any one of the three courses based on your requirement or you may enroll in all three together.

Importance of Data Science

Data Science has changed the decision-making process of businesses completely by allowing them to take decisions based on facts and analysis rather than on prediction. A few ways in which Data Science is important to domains

  • Informed Decision making- Data-driven decisions help domains to reduce risks in planning and decision making.
  • Trends and Patterns- Data Science professionals study trends and patterns from data that domains use in deciding the correct actions to be taken.
  • Customer behavior- Data Science studies consumer habits based on customer data and search-related data, which helps domains to reach more customers.
  • Areas of improvement- Based on the findings and performances, domains improve their products, service, and customer interactions.

What is Cyber Security?

True to its meaning, Cyber Security is the security of electronics, networks, and data systems from unauthorized sources. As the importance of data is growing, more and more domains are digitizing their systems which makes it essential for Cyber security professionals to keep learning new technologies, upgrading their skills and applying innovative ideas to secure organizations against cyber criminals. 

There are 5 types of Cyber Security

  1. Application Security
  2. Data Security
  3. Network Security
  4. Mobile Security
  5. Cloud Security

How does Cyber security work?

The job of Cyber Security is to create a strong defense on all levels of the business whether it is the business data, employee details, business processes, or technology used. Cyber Security protects the organization against cyber attacks, unauthorized access, and breaches. These threats, if not stopped, can result in unwanted access, misuse of information or simply its destruction.

Some of the job roles in data security are building system firewalls, authorizing access, risk detection, monitoring system, eliminating threats and identifying cyberattacks. Cyber Security is also responsible for designing the security policies and then communicating to the employees about the security system.

Career in Cyber Security

By now we have established how important Cyber Security is to domains. All the major domains including government, military, healthcare, finance and technology hire Cyber Security professionals. You can start your career with degree courses in computer science, IT or cyber security for entry-level positions. However, for lead roles in organizations, a master’s degree or years of experience is required. There are different certification courses CISA, CISSP, CEH which help in securing good jobs in cybersecurity

Importance of Cyber Security

Cyber Security is a very important field for all government or non-governmental organizations as it secures systems networks. Domains hire new employees as well as train their current employees in cyber security. Let us discuss a few ways in which cyber security is important for major domains

  • Data Security– Implementing skills, practices, and technologies to secure an organization’s confidential data.
  • Reduce loss from cyber attacks– Cyberattcaks cost huge amounts of money, loss of reputation, and customer mistrust. Cyber Security is the only way to safeguard against cyber attacks.
  • Digitization– It is important to train organizations and their employees in the process of digitization.

Now that we know the basic concepts of Cyber Security and Data Science, let us distinguish between the fields with a head-to-head comparison.
