ABSTRACT
Cybersecurity has been a mainstream challenge over the years for security analysts and architects alike. The changes in the scenario for virtually accomplishing almost every regular activity, due to the coronavirus pandemic, have only increased the use of systems around the globe. With the increase in such usage of systems, it is essential to better design systems concerning their security aspects. It is essential to understand the basic security services that a system must comply with, to avoid scenarios of becoming compromised in terms of a breach or an attack. This chapter covers general security services and the modeling aspects associated with any system. It also looks at the latest research done on such services and security models in recent times. We explore the risks associated with a system and how, for a specific use-case of virtual reality implementation, we task the reader to see what risks can be mapped out and tackled. This chapter acts as a baseline for an individual to understand security services, the risks associated with a system, and the security models available that can be used while designing any system.
