A significant portion of our activities occurs online, leaving behind a digital trail. We conduct shopping transactions through online platforms or applications, where we input sensitive financial details like credit card information. Social media platforms are used to share personal photos and information. Additionally, many of us work remotely, necessitating the storage and transmission of sensitive company data online, ranging from employee records to proprietary information.

As new technologies like artificial intelligence (AI) and cryptocurrency become more common, there has been a huge increase in cyber attacks – 2138 cyber attacks per organization in 2023, as per This means there’s a big need for experts in cybersecurity to protect against these attacks. A report by Cybercrime Magazine says that in 2023, there were approximately  3.5 million unfilled jobs in cybersecurity worldwide. And right now, there’s basically no one unemployed in the cybersecurity field.

Importance of Cyber Security

The significance of cyber security spans across various sectors of the economy, including government agencies, military, corporate, finance, and medicine. Some of the major advantages of cyber security are:
