IMPORTANCE OF CYBER SECURITY
The next main question that arises, is that Is Cyber Security Important? With an increasing number of users, devices, and programs in the modern enterprise, combined with the increasing usage of data — much of which is sensitive or confidential — the importance of cybersecurity continues to grow. Not just on the industry or organizational level but the importance of cyber security tends to remain the same at a personal level also. With the advancements and growth in various technologies, the risk of attacks and threats is increasing day by day, and to defend against those attacks, the importance of cyber security takes place.
