CN-Series devices obtain a VM-Series authorization key from Panorama. Panorama is the centralized management platform for Palo Alto Networks firewalls, including CN-Series and VM-Series. It provides the necessary authorization keys and other configurations to ensure proper deployment and operation of the firewalls.

Geneve (Generic Network Virtualization Encapsulation) is the protocol used for communication between VM-Series firewalls and a Gateway Load Balancer (GWLB) in AWS. Geneve provides a flexible encapsulation method and is specifically supported for integrating with AWS GWLB to ensure seamless traffic flow and security inspection.

The CN-Series firewalls are specifically designed to secure containerized environments. They can secure traffic between Kubernetes pods, which are the smallest deployable units in a Kubernetes cluster, and are often composed of one or more containers. The primary focus of CN-Series firewalls is to ensure security within Kubernetes environments by managing traffic and enforcing security policies at the pod level.

NAT (Network Address Translation) protects and hides an internal network in an outbound flow by translating internal private IP addresses to a public IP address. This process masks the internal IP addresses from external networks, providing security and privacy for the internal network. NAT is commonly used in outbound traffic to allow multiple devices on a local network to communicate with external networks while appearing as a single IP address.

For deploying VM-Series firewalls in an AWS environment, it is important to note that only active-passive HA is supported. This setup ensures that one firewall handles the traffic while the other remains in standby mode, ready to take over in case the active firewall fails. This limitation is essential to consider when planning for high availability and fault tolerance in AWS deployments.

For deploying VM-Series firewalls in high availability (HA), it is crucial to ensure that both firewalls in the HA pair have identical licenses and subscriptions to ensure feature parity and uninterrupted service during failover. Additionally, both firewalls must be deployed on the same type of hypervisor to ensure compatibility and proper synchronization of state and configurations between the active and passive units.

When implementing active-active high availability (HA), a floating IP address must be configured to allow the HA pair to share a single IP address that may be used as the network's gateway IP address. This floating IP address ensures that either of the active-active firewalls can assume control of the traffic without interruption in case of a failover.

Zero Trust implementation revolves around the principle that no entity, inside or outside the network, should be trusted by default. The primary methods that benefit an organization are:

Security automation is seamlessly integrated: Zero Trust requires continuous monitoring and verification of every device and user attempting to access resources. Automation helps in efficiently managing these processes, ensuring that security policies are consistently enforced without human error. Automated tools can quickly detect anomalies, respond to threats, and update access controls dynamically.

Tags in a VM-Series firewall environment allow administrators to dynamically adjust security policy rules based on changes within the virtual environment. These tags can be used to label and categorize virtual machines (VMs) or other entities within the environment, and policies can be created to automatically respond to these tags. This facilitates adaptive security measures that align with the current state and requirements of the environment.
