Abstract
The world is changing, for good or for bad — only we can decide and help shape it. This paper explores and examines the faster-than-ever changing security landscape, including cyber security vulnerabilities, modern threats, threats that these methods pose, and various issues that arose in subsequent years and continue to threaten the digital environment and our world. It reviews different countermeasures for these threats, evaluates and compares different security tools, from legacy to state-of-the-art and artificial intelligence (AI)-based new ones, which help to mitigate those evolving threats and dangers. Finally, the paper assesses the current situation in the cyber security job market, personnel and security management.
