Paloalto Networks PSE-SoftwareFirewall - Palo Alto Networks Systems Engineer (PSE): Software Firewall Professional

The CN-Series firewalls are specifically designed to secure Kubernetes and containerized environments, making them ideal for protecting microservices-based applications. They provide network security by integrating directly with the container orchestration platform.

YAML File Structure:

The structure of a YAML file repository for managing configurations typically follows the order of Kubernetes/Deployment_Type/Environment. This hierarchy ensures that the configurations are organized logically, with Kubernetes-specific settings at the top level, followed by the type of deployment, and then the specific environment.

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.

The Cloud NGFW by Palo Alto Networks is a managed cloud service designed to provide advanced network security capabilities within AWS deployments. This service leverages Palo Alto Networks’ technology to deliver scalable and comprehensive security without the need for users to manage the infrastructure themselves. It is ideal for organizations looking to integrate robust security within their cloud environments efficiently.

The VM-Series plugin supports integration with multiple public cloud platforms, including:

Amazon Web Services (AWS):The VM-Series firewalls can be deployed in AWS to provide comprehensive security for cloud applications and data, leveraging AWS's native services and integration capabilities.

Azure:The VM-Series firewalls also integrate with Microsoft Azure, offering advanced security features and policies for applications and data hosted in Azure's cloud environment.

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.

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.

CN-Series for EKS Security:

The CN-Series firewalls are specifically designed to secure Kubernetes environments, such as Amazon EKS. Deploying them in a high availability (HA) pair ensures robust, fault-tolerant security for containerized workloads, providing continuous protection and high availability.

Transit Gateway and Security VPC:

Using a transit gateway in conjunction with a Security VPC is a recommended design for outbound high availability (HA) in AWS. This configuration ensures that traffic can be routed efficiently and securely through the VM-Series firewalls deployed in the Security VPC.
