Updated on 18th Mar, 23 484 Views

Both cyber security and data science are highly competitive and demanding professions. So, it is important for aspirants to have in-depth knowledge of these domains. Possessing the skill to communicate using figures and data is essential for both Cyber Security and Data Science. The domain of cyber security has niche career opportunities as compared to data science, which was called the sexiest job of the 21st century by a Harvard Business Review article in 2012.

In this blog, we will cover the following:

What is Cyber Security?

Cyber Security is a domain and body of knowledge consisting of technologies, practices, and processes to secure networks, systems, and devices, and maintain data privacy from cyber threats, cyberattacks, and unauthorized access. Sometimes, cyber security is also referred to as Information Technology Security; the professionals specializing in this domain are known as cyber security experts. With the increasing volume and sophistication of cyberattacks and cyberthreats, the domain of cyber security has witnessed a threefold increase in the past few years and is expected to continue doing so.

Organizations are now focusing on onboarding the right professionals with the required skill set in cyber security. These days, almost every organization relies on the cloud for data storage. This data, which is present online, is under a cyberthreat every second. Hence, the need for a strong cyber security network is increasing with every passing day.

Importance of Cyber Security

Cyber security finds its importance and application across various sectors in the economy, such as government agencies, military, corporate, finance, medicine, etc. The entire network of data sharing (intra as well as inter) requires a strong cyber security system at place. This has also been one of the driving reasons behind the training and development of employees by organizations. We will explore some of the benefits of cyber security below:

Data security

As a lot of organizational data is available and stored online, it is exposed to numerous threats. Implementation of the best cyber security practices ensures the protection of all kinds of sensitive or confidential organizational data.

Mitigation of cyberattack loss

It is estimated that by 2025, cyberattacks and cybercrimes will cost the world around $10.5 trillion annually. This would, in turn, lead to customer distrust and loss of business reputation. Cyber security measures and strong network security is the only way to mitigate this loss. Hence, organizations around the globe are hiring security experts at higher remuneration levels.

Support for digitization

With almost every customer’s data being available online due to digitization, cyber security has become pertinent for many organizations. Companies have leveraged digitization for offering ease of living to their customers. This has further increased the need for cyber security. Hence, cyber security training and development is conducted in organizations to support the ongoing digitization.
