Free Palo Alto Networks NetSec-Analyst Exam Dumps Questions & Answers

An organization relies heavily on an internal application that utilizes mutual TLS (mTLS) for secure communication between various microservices. The security team wants to gain visibility into this internal mTLS traffic using a Palo Alto Networks firewall. Implementing standard SSL Inbound Inspection has failed, as it breaks the mTLS handshake. What is the most granular and effective approach to inspect this traffic while preserving the integrity of the mTLS connection, or if preservation is impossible, what is the best alternative for visibility?

• A.Configure SSL Forward Proxy decryption with the firewall's root CA distributed to all microservices.
• B.Apply a 'No Decryption' policy for the mTLS traffic and rely on endpoint security for visibility.
• C.For true mTLS decryption, packet capture and offline analysis are often required, as inline decryption by a firewall breaks the mutual authentication. The firewall should be configured for 'No Decryption' for this specific traffic, and alternative logging (e.g., application logs, NetFlow) used for metadata.
• D.Implement SSL Inbound Inspection, but manually import both server and client certificates and private keys for all communicating microservices onto the firewall for re-signing.
• E.Utilize 'SSL Decryption Excluding Server Certificates' by importing only the server certificates (not private keys) of the microservices into a decryption profile, allowing inspection up to the certificate exchange phase.

A large enterprise utilizes a Palo Alto Networks firewall for its perimeter security. They have stringent compliance requirements, necessitating that all 'traffic', 'threat', and 'URL' logs be sent to a centralized logging platform (10.0.0.10) over UDP, while 'system' and 'configuration' logs must be sent to an internal audit server (10.0.0.20) over TCP, specifically in a custom format called 'AuditLogFormat'. All other log types should not be forwarded externally. The solution must be highly efficient and avoid sending unnecessary data.

• A.Implement two Log Forwarding Profiles. Profile 'LFP_Main' for 10.0.0.10 (UDP, default format) selecting 'traffic', 'threat', 'URL' in its 'Included Log Types'. Profile 'LFP_Audit' for 10.0.0.20 (TCP, 'AuditLogFormat') selecting 'system', 'configuration'. 'LFP_Main' will be attached to Security Policies. 'LFP_Audit' will be selected under 'Device Log Settings' for System and Configuration logs.
• B.It's not possible to apply specific log types to different destinations using a single Log Forwarding Profile with distinct formats and transport protocols for each. Multiple profiles are mandatory, and applying them globally or to specific policies can be complex.
• C.Configure a single Log Forwarding Profile. For 10.0.0.10 (UDP, default), set a filter:
  
• D.Create a single Log Forwarding Profile. Add 10.0.0.10 (UDP) with filters for 'traffic', 'threat', 'URL'. Add 10.0.0.20 (TCP, 'AuditLogFormat') with filters for 'system', 'configuration'. Apply this profile to all relevant security rules, as well as the 'Device -> Log Settings -Y System' and 'Device Log Settings Configuration' sections.
• E.Create two Log Forwarding Profiles. Profile 'Pl' for 10.0.0.10, include 'traffic', 'threat', 'URL'. Profile 'P2' for 10.0.0.20, include 'system', 'configuration', set 'AuditLogFormat'. Apply 'Pl' to security policies and 'P2' to global settings.

A large e-commerce platform is experiencing intermittent slowdowns during peak shopping hours. Analysis shows a surge in new TCP connections from various source IPs, many of which appear to be legitimate but are overwhelming the server's connection table. The security team suspects a sophisticated SYN flood attack that mimics legitimate traffic. Which of the following DoS protection profile settings, when applied to the relevant security rule, would be most effective in mitigating this specific type of attack without significantly impacting legitimate user experience, and why?

• A.Utilize 'SYN Flood Protection' with 'Action: Protect' and a 'Max Concurrent Sessions' threshold set significantly lower than the server's capacity, combined with 'Client Hello Timeout' to quickly identify incomplete handshakes.
• B.Configure 'IP Address Block' for sources exceeding a 'Connection Rate' of 1000 connections/second for 60 seconds to immediately blackhole attacking IPs.
• C.Activate 'SYN Cookies' with a high 'Activation Rate' and a low 'Alarm Rate' to quickly drop malicious SYN requests while allowing legitimate ones to proceed.
• D.Enable 'Random Early Drop (RED)' on the 'TCP Flood' DoS protection profile with a very low 'Low Threshold' to aggressively drop connections before the server is overwhelmed.
• E.Implement 'Path Monitoring' with 'Action: Block' to identify and block suspicious paths, ensuring only trusted routes are used for traffic.

A cybersecurity firm manages numerous Palo Alto Networks firewalls for clients, leveraging Panoram a. They need to implement a security policy where certain applications (e.g., specific SaaS apps) are only accessible from specific source IP ranges, which are dynamically updated via an external asset management system. Furthermore, different client firewalls may have different source IP ranges for the same application. How can this be achieved in Panorama using variables and dynamic objects efficiently, without creating a unique policy for every client and every application?

• A.Utilize Panorama's Variables' within a shared Security Policy Rule. The source IP ranges for the applications would be defined as 'Runtime Variables' that are dynamically populated per device group, or using 'Device Group Variables' that override a default value. Dynamic Address Groups (DAGs) would be used for the application FQDNs, updated by an external script.
• B.Configure 'Policy Based Forwarding' rules on each firewall to direct traffic for specific applications to different egress interfaces based on the source IP, bypassing security policies for this specific requirement.
• C.Use a single security policy rule applying to all firewalls. The source IP ranges are hardcoded into the rule, and administrators manually update them whenever the external asset management system changes.
• D.Employ 'Application Filters' in security policies to match applications. The source IP enforcement is handled by network ACLs upstream of the firewalls.
• E.Create a separate device group and template stack for each client, and within each stack, define unique address objects and security policies for every application based on the client's specific IP ranges.

A company is experiencing performance issues with their cloud-based CRM application (e.g., Salesforce), which uses App-ID: salesforce-base. Users in remote branches report slow response times, even though their internet links appear healthy. Investigation reveals occasional transient packet loss spikes and latency jitter affecting the application's performance. The network team wants to implement an SD-WAN policy that proactively steers Salesforce traffic away from paths experiencing degradation, even if the degradation is intermittent and temporary. Which of the following is the most appropriate configuration?

• A.Implement QOS policies on the WAN interfaces to prioritize Salesforce traffic. Configure a separate security policy for Salesforce to always use the most direct internet link, bypassing SD-WAN intelligence.
• B.Configure health checks on all internet-facing interfaces. If any interface experiences degradation, manually disable that interface in the network configuration to force traffic to other links.
• C.Utilize a standard static route for Salesforce traffic to a primary internet link. Implement BFD (Bidirectional Forwarding Detection) on the link to rapidly detect failures and switch to a pre-configured backup static route.
• D.Create an SLA profile for Salesforce with strict thresholds for latency and packet loss. Configure a PBF rule for Salesforce traffic, and within the PBF, specify a primary path and a secondary path. The PBF will automatically failover if the primary path violates the SL
• E.Define an SD-WAN policy for Salesforce. Use 'Dynamic Path Selection' with an SLA profile that monitors latency, jitter, and packet loss. Set the 'Path Selection Type' to 'Best Path' and configure multiple preferred paths. The system will continuously evaluate paths and select the one currently meeting the SLA.
