TLS decryption is the offering that inspects encrypted outbound traffic. TLS decryption is a feature that allows the firewall to decrypt and inspect outbound SSL/TLS traffic from internal clients to external servers. TLS decryption can inspect encrypted outbound traffic by applying threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis, to the decrypted traffic and blocking any malicious content or activity. WildFire, Content-ID, and Advanced URL Filtering (AURLF) are not offerings that inspect encrypted outbound traffic, but they are related solutions that can enhance security and visibility.

CN-Series firewall can protect communications between Dockers by firewalling. Dockers are software platforms that provide containerization technology for packaging and running applications in isolated environments. Communications between Dockers are network connections between containers within a Docker host or across Docker hosts. CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. CN-Series firewall can protect communications between Dockers by firewalling, which is the process of inspecting and enforcing security policies on network traffic based on application, user, content, and threat information. CN-Series firewall can also leverage threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis, to block any malicious content or activity in the communications between Dockers. CN-Series firewall does not protect communications between Dockers by runtime security, vulnerability management, or data loss prevention (DLP), as those are not features or functions of CN-Series firewall.

Access to the Cloud NGFW for AWS console must be enabled when using Terraform templates with a Cloud next-generation firewall (NGFW) for Amazon Web Services (AWS). Terraform is an open-source tool that allows users to define and provision infrastructure as code using declarative configuration files. Terraform templates are files that specify the resources and configuration for deploying and managing infrastructure components, such as firewalls, load balancers, networks, or servers. Cloud NGFW for AWS is a cloud-native solution that provides comprehensive security and visibility across AWS environments, including VPCs, regions, accounts, and workloads. Cloud NGFW for AWS is deployed and managed by Palo Alto Networks as a service, eliminating the need for customers to provision, configure, or maintain any infrastructure or software. Access to the Cloud NGFW for AWS console must be enabled when using Terraform templates with a Cloud NGFW for AWS, as the console is the web-based interface that allows customers to view and manage their Cloud NGFW for AWS instances, policies, logs, alerts, and reports. The console also provides the necessary information and credentials for integrating with Terraform, such as the API endpoint, access key ID, secret access key, and customer ID. AWS CloudWatch logging, access to the Palo Alto Networks Customer Support Portal, and AWS Firewall Manager console access do not need to be enabled when using Terraform templates with a Cloud NGFW for AWS, as those are not required or relevant components for Terraform integration.

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.

NAT is the element that protects and hides an internal network in an outbound flow. NAT is a feature that translates the source or destination IP address or port of a packet as it passes through the firewall. NAT can protect and hide an internal network in an outbound flow by replacing the private IP addresses of the internal hosts with a public IP address of the firewall or another device, making them appear as a single entity to the external network. This prevents external hosts from directly accessing or identifying the internal hosts, and also conserves the public IP address space. DNS sinkholing, User-ID, and App-ID are not elements that protect and hide an internal network in an outbound flow, but they are related features that can enhance security and visibility.
