PSE-Strata-Pro-24 Exam Dumps : Palo Alto Networks Systems Engineer Professional - Hardware Firewall

Advanced WildFire is Palo Alto Networks' cloud-based malware analysis and prevention solution. It determines whether files are malicious by executing them in a sandbox environment and observing their behavior. To address the customer's concern about the file categorization, the systems engineer must provide evidence of the file's behavior. Here’s the analysis of each option:

Option A: Review the threat logs for information to provide to the customer

Threat logs can provide a summary of events and verdicts for malicious files, but they do not include the detailed behavior analysis needed to convince the customer.

While reviewing the logs is helpful as a preliminary step, it does not provide the level of proof the customer needs.

This option is not sufficient on its own.

Option B: Use the WildFire Analysis Report in the log to show the customer the malicious actions the file took when it was detonated

WildFire generates an analysis report that includes details about the file's behavior during detonation in the sandbox, such as network activity, file modifications, process executions, and any indicators of compromise (IoCs).

This report provides concrete evidence to demonstrate why the file was flagged as malicious. It is the most accurate way to assure the customer that WildFire's decision was based on observed malicious actions.

This is the best option.

Option C: Open a TAG ticket for the customer and allow support engineers to determine the appropriate action

While opening a support ticket is a valid action for further analysis or appeal, it isnot a direct way to assure the customer of the current WildFire verdict.

This option does not directly address the customer’s request for immediate proof.

This option is not ideal.

Option D: Do nothing because the customer will realize Advanced WildFire is right

This approach is dismissive of the customer's concerns and does not provide any evidence to support WildFire's decision.

This option is inappropriate.

WildFire Analysis Reports

When high traffic from Palo Alto Networks NGFWs to Active Directory servers causes performance issues, optimizing the way NGFWs gather user-to-IP mappings is critical. Palo Alto Networks offers multiple ways to collect user identity information, andCloud Identity Engineprovides a solution that reduces the load on AD servers while still ensuring efficient and accurate mapping.

Option A (Correct):Cloud Identity Engineallows NGFWs to gather user-to-IP mappings directly from Active Directory authentication logs or other identity sources without placing heavy traffic on the AD servers. By leveraging this feature, the NGFW can offload authentication-related tasks and efficiently identify users without overloading AD servers. This solution is scalable and minimizes the overhead typically caused by frequent User-ID queries to AD servers.

Option B:UsingGlobalProtect Windows SSOto gather user information can add complexity and is not the most efficient solution for this problem. It requires all users to install GlobalProtect agents, which may not be feasible in all environments and can introduce operational challenges.

Option C:Data redistributioninvolves redistributing user-to-IP mappings from one NGFW (hub) to other NGFWs (spokes). While this can reduce the number of queries sent to AD servers, it assumes the mappings are already being collected from AD servers by the hub, which means the performance issue on the AD servers would persist.

Option D:UsingGlobalProtect agentsto gather user information is a valid method for environments where GlobalProtect is already deployed, but it is not the most efficient or straightforward solution for the given problem. It also introduces dependencies on agent deployment, configuration, and management.

How to Implement Cloud Identity Engine for User-ID Mapping:

EnableCloud Identity Enginefrom the Palo Alto Networks console.

Integrate the Cloud Identity Engine with the AD servers to allow it to retrieve authentication logs directly.

Configure the NGFWs to use the Cloud Identity Engine for User-ID mappings instead of querying the AD servers directly.

Monitor performance to ensure the AD servers are no longer overloaded, and mappings are being retrieved efficiently.

Cobalt Strike is a popular post-exploitation framework often used by attackers for Command and Control (C2) operations. Malleable C2 profiles allow attackers to modify the behavior of their C2 communication, making detection more difficult. Stopping these attacks inreal timerequires deep inline inspection and the ability to block zero-day and evasive threats.

Why "Advanced Threat Prevention and PAN-OS 10.2" (Correct Answer B)?Advanced Threat Prevention (ATP) on PAN-OS 10.2 usesinline deep learning modelsto detect and blockCobalt Strike Malleable C2 attacksin real time. ATP is designed to prevent evasive techniques and zero-day threats, which is essential for blocking Malleable C2. PAN-OS 10.2 introduces enhanced capabilities for detecting malicious traffic patterns and inline analysis of encrypted traffic.

ATP examines traffic behavior and signature-less threats, effectively stopping evasive C2 profiles.

PAN-OS 10.2 includes real-time protections specifically for Malleable C2.

Why not "Next-Generation CASB on PAN-OS 10.1" (Option A)?Next-Generation CASB (Cloud Access Security Broker) is designed to secure SaaS applications and does not provide the inline C2 protection required to stop Malleable C2 attacks. CASB is not related to Command and Control detection.

Why not "Threat Prevention and Advanced WildFire with PAN-OS 10.0" (Option C)?Threat Prevention and Advanced WildFire are effective for detecting and preventing malware and known threats. However, they rely heavily on signatures and sandboxing for analysis, which is not sufficient for stoppingreal-time evasive C2 traffic. PAN-OS 10.0lacks the advanced inline capabilities provided by ATP in PAN-OS 10.2.

Why not "DNS Security, Threat Prevention, and Advanced WildFire with PAN-OS 9.x" (Option D)?While DNS Security and Threat Prevention are valuable for blocking malicious domains and known threats, PAN-OS 9.x does not provide the inline deep learning capabilities needed for real-time detection and prevention of Malleable C2 attacks. The absence of advanced behavioral analysis in PAN-OS 9.x makes this combination ineffective against advanced C2 attacks.
