Free Practice Questions for Paloalto Networks PSE-SoftwareFirewall Exam

Identifying Unknown Vulnerabilities:

Network runtime security is beneficial because it can identify unknown vulnerabilities that are not listed in known CVE lists. This type of security focuses on monitoring the behavior of applications and containers in real-time, which helps detect anomalies and potential threats that static analysis might miss.

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.

Within a Cisco ACI architecture, Palo Alto Networks Next-Generation Firewalls (NGFWs) are deployed using service graphs. Service graphs in Cisco ACI define the sequence of network services that traffic must pass through. By configuring service graphs, administrators can seamlessly integrate Palo Alto Networks firewalls into the fabric to inspect and secure traffic flows.

NAT (Network Address Translation) protects and hides an internal network in an outbound flow by translating internal private IP addresses to a public IP address. This process masks the internal IP addresses from external networks, providing security and privacy for the internal network. NAT is commonly used in outbound traffic to allow multiple devices on a local network to communicate with external networks while appearing as a single IP address.

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.

The CN-Series firewalls are purpose-built for securing Kubernetes environments. They provide network security, visibility, and threat prevention specifically tailored to containerized applications and microservices running in Kubernetes.

VM-Series qcow2 image:

The qcow2 image format is commonly used in OpenStack environments. The VM-Series firewalls are provided in the qcow2 format for compatibility with OpenStack.

VM-Series Auto Scaling:

The VM-Series firewalls are designed to integrate with cloud environments like AWS and support auto-scaling. This allows for the deployment of a single auto-scaling group (ASG) of VM-Series firewalls to secure inbound traffic from the internet to AWS application workloads.

Software next-generation firewall (NGFW) credits can be used to enable DNS security on Palo Alto Networks firewalls. These credits allow customers to activate DNS Security service, which provides real-time protection against DNS-based threats by leveraging machine learning and continuous analysis.
