Securing containerized workloads deployed in cloud-native environments requires applying granular security policies, but traditional controls often lack the necessary context of who is accessing which application. This visibility gap makes it difficult for security teams to enforce fine-grained access, often resulting in overly permissive rules that unnecessarily expand the attack surface. CN-Series firewalls now provide qualification and official support for User-ID™ in Kubernetes as CNF mode. This integration allows your security team to transition security enforcement from relying solely on network topology to leveraging precise user identity information. When you implement User-ID™ with CN-Series, you gain improved visibility into application usage, enabling you to apply security policy controls based on the specific user accessing the service. This capability is specifically designed for CN-Series deployments operating within the cloud-native Kubernetes platform. By binding user context to traffic, you ensure security incidents logged, reported, and analyzed provide a complete picture rooted in user actions, transforming the way you approach forensics. You reduce the attack surface significantly by enforcing need-based user access and ensure that security policies are consistently applied across your distributed microservices.
