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

Presented by


About this talk

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. In this cyber notes cast episode, we will explore this subject. To facilitate your listening, we divided our text into topics: What Is a Network Security Perimeter. Why Many Experts Believe the Network Security Perimeter has Become Outdated. Three Changes that Contributed to Making the Network Security Perimeter Obsolete. New Ways to Handle Network Security Today. Internet of Things and the Network Security Perimeter. About senhasegura. Conclusion. Enjoy this Cyber Notes Cast episode!
