Auto scaling templates for VM-Series firewalls enable deployment of a single auto scaling group (ASG) of VM-Series firewalls to secure inbound traffic from the internet to Amazon Web Services (AWS) application workloads. An ASG is a collection of EC2 instances that share similar characteristics and can be scaled up or down automatically based on demand or predefined conditions. Auto scaling templates for VM-Series firewalls are preconfigured templates that provide the necessary resources and configuration to deploy and manage VM-Series firewalls in an ASG on AWS. Auto scaling templates for VM-Series firewalls can be used to secure inbound traffic from the internet to AWS application workloads by placing the ASG of VM-Series firewalls behind an AWS Application Load Balancer (ALB) or a Gateway Load Balancer (GWLB) that distributes the traffic across the firewalls. The firewalls can then inspect and enforce security policies on the inbound traffic before sending it to the application workloads. Auto scaling templates for HA-Series, CN-Series, and IPA-Series firewalls do not enable deployment of a single ASG of VM-Series firewalls to secure inbound traffic from the internet to AWS application workloads, as those are different types of firewalls that have different deployment models and use cases.

Dynamic Address Group is the PAN-OS feature that allows for automated updates to address objects when VM-Series firewalls are setup as part of an NSX deployment. NSX is a software-defined network (SDN) solution that provides network virtualization, automation, and security for cloud-native applications. Dynamic Address Group is an object that represents a group of IP addresses based on criteria such as tags, regions, interfaces, or user-defined attributes. Dynamic Address Group allows Security policies to adapt dynamically to changes in the network topology or workload characteristics without requiring manual updates. When VM-Series firewalls are setup as part of an NSX deployment, they can leverage the NSX tags assigned to virtual machines (VMs) or containers by the NSX manager or controller to populate Dynamic Address Groups and update Security policies accordingly. Boundary automation, Hypervisor integration, and Bootstrapping are not PAN-OS features that allow for automated updates to address objects when VM-Series firewalls are setup as part of an NSX deployment, but they are related concepts that can be used for other purposes.

To deploy a VM-Series firewall on NSX, you need to enable communication between Panorama and the NSX Manager. This allows Panorama to receive information about the virtual machines and services in the NSX environment. You also need to register the VM-Series firewall as a service on the NSX Manager. This allows NSX to redirect traffic to the VM-Series firewall for inspection3.

The two deployment modes of VM-Series firewalls that are supported across NSX-T are:

• Bootstrap
• Service Cluster

NSX-T is a software-defined network (SDN) solution that provides network virtualization, automation, and security for cloud-native applications. Bootstrap is a method of deploying and configuring VM-Series firewalls in NSX-T using a bootstrap package that contains the initial setup information, such as licenses, certificates, software updates, and configuration files. Service Cluster is a mode of deploying VM-Series firewalls in NSX-T as a group of firewalls that act as a single logical firewall to provide scalability and high availability. Prism Central, Host-based, and Service Insertion are not deployment modes of VM-Series firewalls in NSX-T, but they are related concepts that can be used for other purposes.

CN-Series high availability (HA) pair is the best solution for securing an EKS environment. EKS is a managed service that allows users to run Kubernetes clusters on AWS. CN-Series is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. CN-Series HA pair consists of two CN-Series firewalls deployed in active-passive mode to provide redundancy and failover protection. VM-Series single host, PA-Series using load sharing, and API orchestration are not optimal solutions for securing an EKS environment, as they do not offer the same level of integration, scalability, and automation as CN-Series.

The two methods of Zero Trust implementation that can benefit an organization are:

• Boundaries are established
• Access controls are enforced

Zero Trust is a security model that assumes no trust for any entity or network segment, and requires continuous verification and validation of all connections and transactions. Zero Trust implementation can benefit an organization by improving its security posture, reducing its attack surface, and enhancing its visibility and compliance. Boundaries are established is a method of Zero Trust implementation that involves defining and segmenting the network into smaller zones based on data sensitivity, user identity, device type, or application function. Boundaries are established can benefit an organization by isolating and protecting critical assets from unauthorized access or lateral movement. Access controls are enforced is a method of Zero Trust implementation that involves applying granular security policies based on the principle of least privilege to each zone or connection. Access controls are enforced can benefit an organization by preventing data exfiltration, malware propagation, or credential theft. Compliance is validated and security automation is seamlessly integrated are not methods of Zero Trust implementation, but they may be potential outcomes or benefits of implementing Zero Trust.

The two actions that can be performed for VM-Series firewall licensing by an orchestration system are:

• Creating a license
• Registering an authorization code

An orchestration system is a software tool that automates and coordinates complex tasks across multiple devices or platforms. An orchestration system can perform various actions for VM-Series firewall licensing by using the Palo Alto Networks Licensing API. The Licensing API is a RESTful API that allows programmatic control of license management for VM-Series firewalls. Creating a license is an action that can be performed for VM-Series firewall licensing by an orchestration system using the Licensing API. Creating a license involves generating a license key for a VM-Series firewall based on its CPU ID and the license type. Registering an authorization code is an action that can be performed for VM-Series firewall licensing by an orchestration system using the Licensing API. Registering an authorization code involves activating a license entitlement for a VM-Series firewall based on its authorization code and CPU ID. Renewing a license and downloading a content update are not actions that can be performed for VM-Series firewall licensing by an orchestration system using the Licensing API, but they are related tasks that can be done manually or through other methods.

Using the management interface as the HA1 backup link helps avoid split brain in active-passive high availability (HA) pair deployment. High availability (HA) is a feature that provides redundancy and failover protection for firewalls in case of hardware or software failure. Active-passive HA is a mode of HA that consists of two firewalls in a pair, where one firewall is active and handles all traffic, while the other firewall is passive and acts as a backup. Split brain is a condition that occurs when both firewalls in an HA pair assume the active role and start processing traffic independently, resulting in traffic duplication, policy inconsistency, or session disruption. Split brain can be caused by network failures, device failures, or configuration errors that prevent the firewalls from communicating their HA status and synchronizing their configurations and sessions. Using the management interface as the HA1 backup link helps avoid split brain in active-passive HA pair deployment. The HA1 interface is used for exchanging HA state information and configuration synchronization between the firewalls. Using the management interface as the HA1 backup link provides redundancy and failover protection for the HA1 interface, ensuring that the firewalls can maintain their HA communication and avoid split brain. Using a standard traffic interface as the HA2 backup, enabling preemption on both firewalls in the HA pair, or using a standard traffic interface as the HA3 link do not help avoid split brain in active-passive HA pair deployment, but they are related features that can enhance performance and reliability.

The two private cloud environments that Palo Alto Networks have deep integrations with are:

• VMware NSX-T
• Cisco ACI

A private cloud environment is a cloud computing service that provides infrastructure as a service (IaaS) or platform as a service (PaaS) to customers within a private network or data center. A private cloud environment requires network security that can protect the traffic between different virtual machines (VMs) or other resources from cyberattacks and enforce granular security policies based on application, user, content, and threat information. Palo Alto Networks have deep integrations with VMware NSX-T and Cisco ACI, which are two private cloud environments that provide network virtualization, automation, and security for cloud-native applications. VMware NSX-T is a private cloud environment that provides software-defined networking (SDN) and security for heterogeneous endpoints and workloads across multiple hypervisors, containers, bare metal servers, or clouds. Cisco ACI is a private cloud environment that provides application-centric infrastructure (ACI) and security for physical and virtual endpoints across multiple data centers or clouds. Palo Alto Networks have deep integrations with VMware NSX-T and Cisco ACI by enabling features such as dynamic address groups, service insertion, policy redirection, service chaining, orchestration, monitoring, logging, and automation for VM-Series firewalls and Panorama on these platforms. Dell APEX and Nutanix are not private cloud environments that Palo Alto Networks have deep integrations with, but they are related platforms that can be used for other purposes.
