In AWS, VM-Series firewalls support only active-passive high availability (HA) configuration. This means that one firewall is active and processing traffic, while the other remains passive and takes over in the event of a failure. This design consideration ensures continuous availability and reliability of firewall services in the AWS environment.

Containers are typically designed to run a specific application or service, meaning they have a limited and well-defined set of processes. This makes it easier to implement and manage runtime security based on allow lists, as any deviation from the expected processes can be quickly identified and mitigated.

Reference: Security best practices for container environments emphasize the use of allow lists to enforce runtime security, leveraging the predictable nature of container processes.

Full set of APIs enabling programmatic control of policy and configuration:

Palo Alto Networks provides a comprehensive set of APIs that allow for the automation and orchestration of security policies and configurations in an SDN environment.

OpenShift:

The CN-Series firewall supports deployment in Red Hat OpenShift environments. OpenShift is a Kubernetes-based container platform that provides a comprehensive solution for container orchestration.

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.

For a customer deploying VM-Series firewalls in a private data center and concerned about protecting resources from malware and lateral movement, the following subscriptions are recommended:

Threat Prevention:This subscription provides comprehensive threat detection and prevention capabilities, including IPS, anti-virus, anti-spyware, and vulnerability protection.

WildFire:This advanced threat intelligence service analyzes suspicious files and identifies new malware, providing protection against zero-day exploits and threats.

Prospects interested in Palo Alto Networks virtualized next-generation firewalls (NGFWs) can achieve improved return on investment (ROI) through the following factors:

Reduced operational expenditures: Virtualized NGFWs reduce the need for physical hardware, lowering the costs associated with purchasing, maintaining, and managing hardware appliances. This also includes savings on power, cooling, and physical space requirements.

App-ID is a feature that provides application-based segmentation and helps prevent lateral threat movement within a network. By identifying and controlling applications traversing the network regardless of port, protocol, or encryption (SSL or SSH), App-ID allows granular security policies to be applied, thereby limiting the spread of threats within the network.

Service Cluster Mode:

In NSX-T, the Service Cluster mode allows the VM-Series firewalls to be deployed as part of a service cluster, where they can provide security services to workloads.
