Cyber Notes Cast - Network Security Perimeter Why Is This Concept Obsolete

For a long time, companies had data centers as their IT infrastructures, which needed to be protected from external agents. Business-critical data was embedded in these allocations, including internal networks, client devices, Internet gateways, applications, and servers. To protect these assets, firewalls, antivirus programs, intrusion systems, and demilitarized zones were used, separating those who had access authorization from those who did not. In this type of structure, anyone could access most of the network, regardless of their need and the tasks they performed in the company. On the other hand, accessing it remotely was a major challenge due to the Network Security Perimeter. The digital transformation process, along with the migration of infrastructures to the cloud and the adoption of remote work models, has led companies to decentralize their infrastructures. One of the direct consequences of this movement was the development and adoption of Zero Trust-based models and micro-segmentation, since the Network Security Perimeter has become inefficient.
