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 factors that lead to improved return on investment for prospects interested in Palo Alto Networks virtualized next-generation firewalls (NGFWs) are:

• Decreased likelihood of data breach
• Reduced time to deploy

Palo Alto Networks virtualized NGFWs are virtualized versions of the Palo Alto Networks next-generation firewall that can be deployed on various cloud or virtualization platforms. Palo Alto Networks virtualized NGFWs provide comprehensive security and visibility across hybrid and multi-cloud environments, protecting applications and data from cyberattacks. By using Palo Alto Networks virtualized NGFWs, prospects can decrease the likelihood of data breach by applying granular security policies based on application, user, content, and threat information, and by leveraging cloud-delivered services such as Threat Prevention, WildFire, URL Filtering, DNS Security, and Cortex Data Lake. By using Palo Alto Networks virtualized NGFWs, prospects can also reduce the time to deploy by taking advantage of automation and orchestration tools such as Terraform, Ansible, CloudFormation, ARM templates, and Panorama plugins that simplify and accelerate the deployment and configuration of firewalls across different cloud platforms. Reduced operational expenditures and reduced insurance premiums are not factors that lead to improved return on investment for prospects interested in Palo Alto Networks virtualized NGFWs, but they may be potential benefits or outcomes of using them.

Deployment of the NSX Distributed Firewall (DFW) must be configured in an NSX environment to ensure proper operation of a VM-Series firewall in order to secure east-west traffic. East-west traffic is the traffic that flows between applications or workloads within a network or a cloud environment. NSX environment 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. NSX DFW is a feature that provides distributed stateful firewalling at the hypervisor level for every virtual machine (VM) in an NSX environment. Deployment of the NSX DFW must be configured in an NSX environment to ensure proper operation of a VM-Series firewall in order to secure east-west traffic by enabling features such as service insertion, policy redirection, service chaining, orchestration, monitoring, logging, and automation for VM-Series firewalls and Panorama on NSX environment. VMware Information Sources, User-ID agent on a Windows domain server, and device groups within VMware Services Manager do not need to be configured in an NSX environment to ensure proper operation of a VM-Series firewall in order to secure east-west traffic, as those are not required or relevant components for NSX integration.

Microsegmentation is a technology that allows for granular control of east-west traffic in a software-defined network. Microsegmentation divides the network into smaller segments or zones based on application or workload characteristics, and applies security policies to each segment. This reduces the attack surface and prevents unauthorized access or lateral movement within the network. Routing, MAC Access Control List, and Virtualization are not technologies that provide microsegmentation, but they are related concepts that can be used in conjunction with microsegmentation.

A design consideration for a prospect who wants to deploy VM-Series firewalls in an Amazon Web Services (AWS) environment is that only active-passive high availability (HA) is supported. 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. Active-passive HA is the only mode of HA that is supported for VM-Series firewalls in an AWS environment, due to the limitations of AWS networking and routing. Active-active HA, which is another mode of HA that consists of two firewalls in a pair that both handle traffic and synchronize sessions, is not supported for VM-Series firewalls in an AWS environment. A design consideration for a prospect who wants to deploy VM-Series firewalls in an AWS environment is not that special AWS plugins are needed for load balancing, resources are shared within the cluster, or high availability (HA) clusters are limited to fewer than 8 virtual appliances, as those are not valid or relevant factors for firewall deployment in an AWS environment.
