NetSec-Pro Sample Questions Answers

To inspect SaaS app traffic (often encrypted), you must configure:

SSL Forward Proxy

“The SSL Forward Proxy decryption profile enables the firewall to decrypt outbound SSL traffic, essential for visibility into SaaS app usage.”

(Source: SSL Forward Proxy Overview)

Validate certificates

“Validating and deploying the appropriate root and intermediate CA certificates is critical for establishing trust and preventing SSL errors during decryption.”

(Source: Certificate Deployment and Validation)

Without these steps, SaaS decryption and policy enforcement would be incomplete.

SD-WANsolutionsoptimize application experienceand provide secure, dynamic connectivity across distributed locations by leveraging real-time path metrics (latency, jitter, loss).

“By implementing SD-WAN, traffic is routed intelligently based on real-time network performance metrics. Zone protection profiles ensure security while maximizing application performance.”

(Source: SD-WAN Architecture)

Key advantage:

Secure connectivity and best user experience across campuses and branches.

Palo Alto Networks'Enterprise DLPuses a centralized DLP profile that can be applied consistently across both Prisma Access and NGFWs using Strata Cloud Manager (SCM). This eliminates the need for duplicating efforts across multiple locations.

“Enterprise DLP profiles are created and managed centrally through the Cloud Management Interface and can be used seamlessly across NGFW and Prisma Access deployments.”

Panorama allows engineers to createcustom reportsand generatePDF summaryformats for consistent reporting across NGFWs.

Custom Reports

“Custom Reports provide tailored reporting based on URL categories, application usage, and threat visibility. They are generated within Panorama and can include data on newly categorized AI URL types.”

Together, these options provide aconsistent, standardized methodto push insights about AI-based URL categories to branch devices.

CASB integration should focus on comprehensive data protection, which includesencryption for data-at-rest and in transit, frequentkey updates, and usingstrong encryption algorithmsto ensure confidentiality and data integrity.

“CASB solutions should enforce encryption for data-at-rest and in transit, implement key rotation policies, and leverage robust encryption algorithms to protect sensitive SaaS application data.”

In cloud environments like Azure, theVM-Series NGFWis deployed to createLayer 3 segmentation zonesclosest to the application workloads.

“In Azure, deploy VM-Series firewalls in Layer 3 mode to enforce security policies closest to private applications, meeting strict compliance and segmentation requirements.”

Layer 3 segmentation ensures security policies are enforced at the right boundary to isolate traffic within Azure’s virtual networks.

To fully leverageinline cloud analysisin Advanced Threat Prevention, security profiles (e.g., anti-spyware) must beupdated or newly createdto enable local deep learning and inline cloud analysis models.

“To activate inline cloud analysis, update your Anti-Spyware profile to enable advanced inline detection engines, including deep learning-based models and cloud-delivered signatures.”

This ensuresreal-time protectionfrom sophisticated threats beyond static signatures.

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.”

(Source: Content-ID Overview)

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

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.”

(Source: IoT Security Logging Requirements)

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.”

(Source: IoT Security Logs)

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

Prisma Access for secure remote access

“Prisma Access extends consistent security and optimized connectivity to branch locations, enabling secure access for mobile and branch users.”

(Source: Prisma Access Overview)

Centralized management for consistent policy enforcement

“Centralized management using Strata Cloud Manager or Panorama ensures security policies and updates are uniformly applied across distributed locations, preventing policy drift and security gaps.”

(Source: Strata Cloud Manager Best Practices)

These two practices are foundational for modern, distributed enterprise networks to maintain security posture and performance.

Dynamic path selectionis the foundation of SD-WAN, leveraging real-time performance data to dynamically route traffic over the best available path.

“Dynamic path selection continuously monitors performance metrics (loss, latency, jitter) and makes real-time routing decisions to ensure application SLAs are met across the WAN.”

(Source: Prisma SD-WAN Dynamic Path Selection)

Establishing dynamic path selection first ensures the rest of the SD-WAN optimizations (e.g., failover, QoS) work effectively.

TheSP3 architectureof Palo Alto NGFWs ensures that additional security services (CDSS) only cause aminor reduction in performance, as traffic is inspected once in a single pass.

“The single-pass parallel processing (SP3) architecture performs application identification and security enforcement simultaneously in one pass, resulting in only minor performance impacts when enabling multiple security services.”

(Source: SP3 Architecture)

Unlike traditional multi-pass engines, SP3 architecture optimizes performance while delivering comprehensive security.

Threat logs for Prisma Access mobile users can be reviewed in bothStrata Cloud Manager (SCM)andStrata Logging Service. Prisma Cloud and service connection firewalls are not directly tied to mobile user traffic logs.

“Prisma Access logs are available in the Strata Cloud Manager and can also be sent to the Strata Logging Service for detailed analysis and threat visibility.”

To allow third-party contractors controlled access, security policies must combineuser identificationandtime-based access controls:

User-ID

“User-ID enables security policies to be based on user identity rather than IP addresses, ensuring precise policy enforcement for specific users such as contractors.”

(Source: User-ID Overview)

Schedule

“Schedules allow policies to be active only during specific times, providing time-based access control (e.g., after business hours).”

(Source: Security Policy Schedules)

Together, they ensure that only authorized users (contractors) have access, and only when explicitly allowed.
