Registering an Authorization Code:

An orchestration system can automate the registration of authorization codes, which is a critical step in licensing the VM-Series firewall. This process involves submitting the code to Palo Alto Networks to activate the license.

The Palo Alto Networks Next-Generation Firewall must be integrated into the Layer 3 underlay network to secure traffic within a Cisco ACI environment.

Reference: Integration documentation for Cisco ACI and Palo Alto Networks indicates the necessity of Layer 3 integration for policy enforcement and traffic management.

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.

VM-Series firewalls provide advanced application-level security for web-server instances on AWS. These virtual firewalls leverage Palo Alto Networks’ next-generation firewall capabilities to offer features like application identification, threat prevention, and URL filtering, ensuring comprehensive security for web applications hosted on AWS.

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.

CN-Series for DevOps deployments:

The CN-Series firewall is specifically designed to secure containerized environments and is ideal for protecting extensive DevOps deployments. It integrates seamlessly with Kubernetes and other container orchestration platforms, providing the necessary security controls for DevOps processes.

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.

In a CN-Series (Cloud Native) environment, protecting communications between Docker containers is crucial. CN-Series firewalls are designed to provide advanced firewalling capabilities within containerized environments:

Firewalling: The CN-Series firewall provides Layer 7 visibility, allowing for application-layer security policies and protections. It ensures that all inter-container traffic is inspected, filtered, and secured according to the defined security policies. This includes blocking malicious traffic, preventing unauthorized access, and providing micro-segmentation within the Kubernetes clusters.

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.

Security Profiles:

Security profiles in Palo Alto Networks firewalls are used to scan for threats in allowed traffic. These profiles include features such as Antivirus, Anti-Spyware, Vulnerability Protection, URL Filtering, and others that inspect traffic and detect potential threats.

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.

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.

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.

Palo Alto Networks has deep integrations with:

Cisco ACI:Integration with Cisco Application Centric Infrastructure (ACI) allows for automated security provisioning and enforcement within the Cisco data center environment, leveraging the tight coupling of network and security policies.

VMware NSX-T:Integration with VMware NSX-T enables advanced security features and visibility within VMware's software-defined data center (SDDC) environment, facilitating automated security policies and enforcement across virtualized workloads.

Ping monitoring:

This mechanism involves monitoring the reachability of a specified IP address. If the firewall cannot ping the address, it may trigger a failover.
