Description: Perimeter security refers to a set of measures designed to protect the boundary of a network, which includes the implementation of firewalls, intrusion detection systems, and other security technologies. Its primary goal is to prevent unauthorized access and protect sensitive data within an organization. In the context of Zero Trust in cloud environments, perimeter security evolves as it acknowledges that traditional network boundaries have diminished due to the adoption of cloud services and the increasing mobility of users. This means that security is no longer solely based on protecting the physical perimeter but extends to continuous verification of users and devices, regardless of their location. Key features of perimeter security include network segmentation, ongoing traffic monitoring, and the implementation of role-based access policies. In a Zero Trust environment, every access attempt is considered potentially insecure, requiring rigorous authentication and authorization before granting access to critical resources. This evolution in perimeter security is crucial to address modern threats, where attacks can originate from both external and internal sources, and where data protection is more important than ever.
