Francis Aidan Ruambo

Abstract: Network Security strategies evolves parallel with the advancement and development of computer systems and services. The ubiquity of ICT devices and services offers undeniable efficiency in executing our daily routine activities. Challenges in the aspects of security and continuous availability of the ICT resources and services, trigger the evolution of network security strategies. In this review paper, a brief overview of evolving strategies adopted within the dynamic paradigm of network security is highlighted and challenges are reviewed. Additionally, interesting areas for future research in securing the computer network ecosystem are suggested. The review finds that, as long as computer systems and services are dynamically evolving, then the network security strategies will also continue to be an evolving and volatile paradigm. In order to enhance network security, there is a need of incorporating new innovative strategies whilst embracing network security best practices and principles to mitigate appropriately the evolving threats within the computer network ecosystem.
