Intrusion Prevention System (IPS):The CN-Series firewalls incorporate an Intrusion Prevention System to detect and prevent exploits and attacks on applications and systems. This feature is essential for securing east-west traffic, as it can identify and block threats within the data center traffic between pods in different trust zones.

Layer 7 Visibility:CN-Series firewalls provide Layer 7 (application layer) visibility, enabling deep inspection of application traffic. This allows the firewall to understand and enforce policies based on the application and its behavior, rather than just ports and protocols, ensuring comprehensive security for east-west traffic within a Kubernetes environment.

The CN-Series firewall prevents data exfiltration by inspecting the content of outbound traffic. It uses advanced security features, such as threat prevention and data loss prevention (DLP), to detect and block suspicious activities and unauthorized data transfers, ensuring sensitive data remains within the secure environment.

Identifying Unknown Vulnerabilities:

Network runtime security is beneficial because it can identify unknown vulnerabilities that are not listed in known CVE lists. This type of security focuses on monitoring the behavior of applications and containers in real-time, which helps detect anomalies and potential threats that static analysis might miss.

CN-Series for DevOps deployments:

The CN-Series firewall is specifically designed to secure containerized environments and is ideal for protecting extensive DevOps deployments. It integrates seamlessly with Kubernetes and other container orchestration platforms, providing the necessary security controls for DevOps processes.

The number of required flex credits for a VM-Series firewall primarily depends on the vCPU allocation. Flex credits are used to license VM-Series firewalls, and the number of credits required is determined by the number of virtual CPUs (vCPUs) allocated to the firewall. Higher vCPU allocations provide greater performance capabilities and thus require more flex credits.

User IP mappings:

Panorama can push user-to-IP mapping information to the NSX manager, enabling dynamic security policy enforcement based on user identity.

Security Profiles:

Security profiles in Palo Alto Networks firewalls are used to scan for threats in allowed traffic. These profiles include features such as Antivirus, Anti-Spyware, Vulnerability Protection, URL Filtering, and others that inspect traffic and detect potential threats.

Consistent Security Across the Environment:

CN-Series firewalls are designed to provide security for containerized environments by protecting traffic between pods and other workload types. This ensures that security policies are consistently enforced across all elements of the environment, maintaining a unified security posture.

VM-Series Auto Scaling:

The VM-Series firewalls are designed to integrate with cloud environments like AWS and support auto-scaling. This allows for the deployment of a single auto-scaling group (ASG) of VM-Series firewalls to secure inbound traffic from the internet to AWS application workloads.

The CN-Series firewalls are purpose-built for securing Kubernetes environments. They provide network security, visibility, and threat prevention specifically tailored to containerized applications and microservices running in Kubernetes.
