Building Security Perimeters to Protect Network Systems Against Cyber Threats [Future Directions]

Due to the wide variety of devices used in computer network systems, cybersecurity plays a major role in securing and improving the performance of the network or system. Although cybersecurity has received a large amount of global interest in recent years, it remains an open research space.
