Introduction to Cyber Security   

Cyber Security includes practices and technologies that safeguard networks and systems against cyberattacks, unauthorised access, and cyber threats. The objective is to prevent third parties from misusing the organisation’s sensitive data.  

Cyber Security is divided into five different fields: 

a) Cloud Security 

b) Critical Infrastructure Security 

c) Application Security 

d) Internet of Things (IoT) security 

e) Network Security  

Role of a Cyber Security Analyst - Explained

A Cyber Security Analyst ensures that an organisation’s networking and computer systems are secured. Cyber Security Analysts carry out this task by identifying any underlying issue in the organisation's software and technology, focusing on Cyber Security Essentials.

These Analysts also carry out the following responsibilities:  

a) Adding firewalls to existing networking systems  

b) Assessing the access permissions   

c) Improving the security of Information Technology infrastructure  

d) Monitoring cyber-attacks on the organisation’s networking systems  

e) Detection and removal of risks related to potential data breaches  

f) Finding out the source of cyber attacks  

g) Ensuring employees of the organisation are familiar with the security policies   

Understanding Data Science    

Data Science simplifies the task of studying complex and large data sets. Consequently, it helps to extract and analyse meaningful data to make informed decisions in real-time. Data Science includes tools, Machine Learning methods, and instructions. These resources are used together to identify new raw data trends.    

Data Science includes five phases: planning, deploying, explaining, evaluating, and monitoring a data-driven model. Professionals who work in the domain of Data Science are known as Data Scientists.    

Data Scientists have the knowledge required to obtain raw data and convert it into an easy-to-analyse format. Next, this data is entered into models and algorithms to gain actionable insights.    

What is the Role of a Data Scientist?    

Data Scientists can collect vast volumes of data, process it, and interpret it for further business use. Next, the data scientist will analyse the information derived to solve the organisation's issues. Most importantly, this data helps in making informed and real-time decisions. Additionally, a Data Scientist must fulfil the following duties: 

1) Carrying out steps involved in data modelling and designing  

2) Creation of algorithms that are used in Machine Learning  

3) Creation and complete maintenance of the database  

4) Evaluating the quality of data  

5) Cleaning unstructured data  

6) Preparation of reports for the project and executive teams  

7) Offering necessary suggestions to the IT management and executive team

How are Cyber Security and Data Science Interrelated?

Cyber Security and Data Science are becoming more interrelated areas that collaborate to improve the security and effectiveness of digital systems. Both fields fundamentally depend on analysing data to guide their methods. Data Science uses statistical techniques, Machine Learning, and predictive analytics to analyse extensive datasets, revealing patterns that are extremely useful for Cyber Security experts.

In the field of Cyber Security, data plays a critical role in detecting potential risks and weaknesses. Data Science techniques assist security teams in identifying potential attacks by examining network traffic and user behaviour for anomalies. For example, Machine Learning Algorithms can be trained on past attack data, enabling systems to more rapidly and precisely identify emerging threats.

On the other hand, Data Science relies on Cyber Security to safeguard the integrity of its data. Ensuring the security of sensitive information is crucial due to increasing worries about data breaches and privacy violations. Strong security measures for cyber Security protect the data analysed by Data Scientists, building confidence in the insights obtained from it.

In short, the interrelation between Cyber Security and Data Science improves an organisation's ability to withstand Cyber threats by allowing for proactive management of risks and using trustworthy data for decision-making.

Tips for Choosing Between Cyber Security and Data Science

If you're thinking about pursuing a profession in either Cyber Security or Data Science, here are some suggestions to assist you in deciding:

1) Evaluate Your Timeline

If you're anxious to start working soon, getting a degree in Cyber Security usually takes less time. After finishing a four-year bachelor's degree, it is common to begin in an entry-level role. Although some positions in Data Science allow applicants with just a bachelor's degree, a majority prefer candidates with higher-level qualifications. 

2) Assess Your Interest in Business

Both areas require technical skills, however Data Scientists implement their discoveries in real-life business situations. They assess data to assess business situations, anticipate results, and inform decision-making. If you find satisfaction in studying Business Intelligence, a profession in Data Science could be a perfect match. 

In contrast, Cyber Security experts prioritise protecting infrastructures according to business requirements and commonly perform separate technical duties. They commonly collaborate with business specialists to establish requirements and create suitable security solutions.

3) Reflect on Your Skills

Both disciplines necessitate programming, critical thinking, and problem-solving skills, but they each call for distinct areas of expertise. If you are skilled in Mathematics and Statistics and like working with different programming languages, Data Science might be a better fit for you. Data Scientists frequently possess a solid background in Machine Learning and Data Visualisation methods.
