CN-Series firewalls are specifically designed for containerized environments.
Why A, C, and E are correct:
A. Prevention of sensitive data exfiltration from Kubernetes environments: CN-Series provides visibility and control over container traffic, enabling the prevention of data leaving the Kubernetes cluster without authorization.
C. Inbound, outbound, and east-west traffic between containers: CN-Series secures all types of container traffic: ingress (inbound), egress (outbound), and traffic between containers within the cluster (east-west).
E. Enforcement of segmentation policies that prevent lateral movement of threats: CN-Series allows for granular segmentation of containerized applications, limiting the impact of breaches by preventing threats from spreading laterally within the cluster.
Why B and D are incorrect:
B. All Kubernetes workloads in the public and private cloud: While CN-Series can protect Kubernetes workloads in both public and private clouds, the statement "all Kubernetes workloads" is too broad. Its focus is on securing the network traffic around those workloads, not managing the Kubernetes infrastructure itself.
D. All workloads deployed on-premises or in the public cloud: CN-Series is specifically designed for containerized environments (primarily Kubernetes). It's not intended to protect all workloads deployed in any environment. That's the role of other Palo Alto Networks products like VM-Series, PA-Series, and Prisma Access.
Palo Alto Networks References: The Palo Alto Networks documentation on CN-Series firewalls clearly outlines these use cases. Look for information on:
CN-Series Datasheets and Product Pages: These resources describe the key features and benefits of CN-Series, including its focus on container security.
CN-Series Deployment Guides: These guides provide detailed information on deploying and configuring CN-Series in Kubernetes environments.
These resources confirm that CN-Series is focused on securing container traffic within Kubernetes environments, including data exfiltration prevention, securing all traffic directions (inbound, outbound, east-west), and enforcing segmentation
