Final Thoughts

The fight against cybersecurity is never-ending. Soon, there won't be a conclusive answer to the issue. The complexity of IT systems, the intrinsic nature of information technology (IT), and human fallibility in forming judgments about what activities and information are safe or hazardous from a cybersecurity viewpoint are the primary causes of cybersecurity challenges.

There are no magic solutions or even combinations of solutions (cybersecurity applications) that will "fix the issue" permanently since none of these variables is anticipated to alter shortly. 

Innovation creates new IT applications. However, it also creates new opportunities for criminals, terrorists, and other adversaries to operate. As a result, improving a system's cybersecurity posture must be seen as a continuous effort rather than something that can be completed once and then ignored.
