Framework Analysis and Zero Trust Security Issues in Contemporary Network Systems

The security perimeter is expanding, so no one can be trusted to permit network or data access. Furthermore, there is a significant danger associated with insider threats, which facilitate data leaks from the network. To strengthen an organization's security posture, zero trust security must totally replace traditional security. In addition to limiting resource access through the principle of least privilege, the zero-trust paradigm emphasises how important it is to authenticate and validate each individual and device. Devices are granted access only after they have received their login credentials and access privileges. User identity, application security, and device security are a few of the factors that decide these. The zero trust framework is a practical way to solve issues with contemporary network systems and secure legacy systems. This article looks at complete framework analysis and zero trust security challenges in a number of contemporary networks,including the financial industry, IoT (Internet of Things), enterprise, and 5G networks.
