PSE-SoftwareFirewall Exam Dumps - Paloalto Networks PSE-Software Firewall Professional Questions and Answers

TLS decryption is the feature that inspects encrypted outbound traffic. By decrypting TLS/SSL traffic, the firewall can inspect the content for threats and enforce security policies. This is crucial for preventing malware and other threats that might hide within encrypted traffic.

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.

Address Group:

Address groups in Palo Alto Networks firewalls allow for the grouping of multiple addresses or address objects. This capability enables the sharing of cloud-learned tags with on-premises firewalls, facilitating the consistent application of security policies across hybrid cloud environments.

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.

Dynamic address groups in Palo Alto Networks firewalls provide flexibility by allowing network resources to be added without requiring changes to existing policies and rules:

Dynamic address group: These groups automatically update based on tags and attributes assigned to network objects. When new resources are added with the appropriate tags, they are dynamically included in the address group, and the associated policies automatically apply to them without manual intervention.

Independent Upgrade:

The VM-Series plugin can be upgraded independently of the PAN-OS version. This allows for flexibility in maintaining and enhancing the plugin without the need for a complete PAN-OS upgrade.

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.

Enabling Threat Prevention on Palo Alto Networks firewalls provides comprehensive protection against inbound threats by inspecting traffic for exploits, malware, and other malicious activities.

Reference: The Threat Prevention service is detailed in the PAN-OS documentation, highlighting its role in securing inbound traffic by leveraging various threat detection and prevention techniques.

Visibility into application-level cluster traffic:

VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster lack the necessary visibility into the traffic and communications occurring at the application level within the cluster. This limitation impedes their ability to effectively protect containerized workloads.
