an increase in cybersecurity issues
The contemporary world, characterized by digitization, has led to an increase in cybersecurity issues. Cybercriminal aims at exploiting the current vulnerabilities through a simple phenomenon such as a virus. The security of a system is based on the unavailability of a virus.
