NetSec-Pro Exam Dumps - Paloalto Networks Network Security Administrator Questions and Answers

A security profile group named“default”is automatically applied to all new security rules unless a specific profile group is explicitly configured.

“If a security profile group named ‘default’ exists, it will be automatically applied to any newly created security policy rules to ensure consistent protection.”

(Source: Security Profile Groups)

This behavior ensures that newly created policies are always protected by default security profiles, minimizing human error.

When implementing SSL Forward Proxy decryption for outbound traffic, two key challenges that must be evaluated are:

Incomplete certificate chains: This occurs when the firewall cannot validate the entire certificate chain for a site, which may cause decryption failures.

Certificate pinning: Applications like banking apps may use certificate pinning to prevent MITM (man-in-the-middle) attacks, and these applications will break if SSL Forward Proxy is used.

“When decrypting outbound SSL traffic, you must consider incomplete certificate chains, which can cause decryption to fail if the firewall cannot validate the entire chain. Also, be aware of certificate pinning in applications that prevents decryption by rejecting forged certificates.”

For IoT Security toaccurately classify and monitorIoT devices, the following logs must be forwarded to Strata Logging Service:

Enhanced application logs– provide detailed application usage and behaviors, essential for profiling device types and roles.

“Enhanced Application logs provide additional context on IoT device behavior and usage patterns, and must be forwarded to Strata Logging Service for IoT Security to build accurate Device-ID profiles.”

Threat logs– essential for detecting suspicious or malicious activities by IoT devices.

“Threat logs are critical for identifying potential exploits or suspicious activities involving IoT devices and are required for accurate threat visibility within IoT Security.”

These logs collectively ensure accurate device classification and real-time threat visibility.

Content-IDis the core of Palo Alto Networks' prevention architecture, providingsingle-pass application layer inspectionto deliver real-time threat prevention across all traffic.

“Content-ID uses a single-pass architecture to perform application-layer (Layer 7) traffic inspection and real-time threat prevention. Unlike traditional firewalls that rely on multiple scans, Content-ID inspects traffic once to enforce multiple security controls simultaneously.”

By consolidating security functions in a single pass, it ensures both efficiency and comprehensive security.

When usingAWS centralized deploymentsfor Cloud NGFW, the service deploys NGFW instances intoselected VPCsas additional workloads to secure that traffic.

“In centralized deployments, Cloud NGFW instances are deployed as security appliances within the selected VPCs, ensuring consistent traffic inspection and protection.”

This approach minimizes complexity and ensures direct security policy enforcement within AWS.

To fully manage a firewall from Strata Cloud Manager (SCM), it’s essential to establish trust and ensure reliable connectivity:

Configure NTP and DNS servers

The firewall must have accurate time (NTP) and name resolution (DNS) to securely communicate with SCM and related cloud services.

“To ensure successful management, configure the firewall’s NTP and DNS settings to synchronize time and resolve domain names such as stratacloudmanager.paloaltonetworks.com.”

Install a device certificate

A device certificate authenticates the firewall’s identity when connecting to SCM.

“The device certificate authenticates the firewall to Palo Alto Networks cloud services, including SCM. It’s a fundamental requirement to establish secure connectivity.”

These steps ensuretrust, secure communication, and successful onboarding into SCM.

Enterprise DLPuses cloud analysis to inspect and classify sensitive data innon-file-based formats(e.g., in-line data streams, SaaS communications).

“Enterprise DLP inspects data in non-file-based traffic flows, forwarding suspicious data patterns to the cloud for classification and verdicts.”

The other services focus on file-based scanning (WildFire), URL access control (Advanced URL Filtering), or inline SaaS application controls (SaaS Security Inline).

When migrating from aperpetual VM-Series firewall license to a flexible VM licensing model, two critical steps are needed:

Allocate same number of vCPUs– This ensures that the VM-Series capacity remains consistent and avoids resource bottlenecks.

“When migrating perpetual VM-Series licenses to flexible VM licensing, allocate the same vCPU and memory resources to ensure equivalent performance.”

(Source: VM-Series Flexible Licensing Migration)

Limit to same security services– Flexible licensing requires maintaining the same security services to preserve licensing compliance.

“Ensure that you allow only the same security services on the flexible VM instance as were licensed on the perpetual VM.”

InPalo Alto Networks' Single-Pass Parallel Processing (SP3)architecture, SSL/TLS decryption occurs only during theslow pathwhen the firewall first encounters a new session.

“SSL/TLS decryption, which requires CPU-intensive cryptographic operations, is performed during the slow path when establishing new sessions. Once decrypted, traffic is processed in the fast path for subsequent packets.”

(Source: Packet Flow and SP3 Architecture)

After the initial decryption in the slow path, decrypted traffic is handled by fast path for efficiency.

In Prisma Access, theinterzonesecurity policy rule isavailableand plays a crucial role in controlling trafficbetweenzones.

“You can configure an interzone rule to control traffic that flows between different zones in Prisma Access, enabling granular security policy enforcement.”

(Source: Prisma Access Security Policies)

This ensures comprehensive control of traffic crossing security boundaries in the cloud-delivered architecture.
