Paloalto Networks PSE-Strata-Pro-24 Exam With Confidence Using Practice Dumps

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

Policy Optimizer is a feature designed to help administrators improve the efficiency and effectiveness of security policies on Palo Alto Networks Next-Generation Firewalls (NGFWs). It focuses on identifying unused or overly permissive policies to streamline and optimize the configuration.

Why "Identify Security policy rules with unused applications" (Correct Answer C)?Policy Optimizer provides visibility into existing security policies and identifies rules thathave unused or outdated applications. For example:

It can detect if a rule allows applications that are no longer in use.

It can identify rules with excessive permissions, enabling administrators to refine them for better security and performance.By addressing these issues, Policy Optimizer helps reduce the attack surface and improves the overall manageability of the firewall.

Why not "Recommend best practices on new policy creation" (Option A)?Policy Optimizer focuses on optimizingexisting policies, not creating new ones. While best practices can be applied during policy refinement, recommending new policy creation is not its purpose.

Why not "Show unused licenses for Cloud-Delivered Security Services (CDSS) subscriptions and firewalls" (Option B)?Policy Optimizer is not related to license management or tracking. Identifying unused licenses is outside the scope of its functionality.

Why not "Act as a migration tool to import policies from third-party vendors" (Option D)?Policy Optimizer does not function as a migration tool. While Palo Alto Networks offers tools for third-party firewall migration, this is separate from the Policy Optimizer feature.

Advanced DNS Security on Palo Alto Networks firewalls is designed to identify and prevent a wide range of DNS-based attacks. Among the listed options, "High entropy DNS domains" is a specific example of a DNS attack that Advanced DNS Security can detect and block.

Why "High entropy DNS domains" (Correct Answer A)?High entropy DNS domains are often used in attacks where randomly generated domain names (e.g., gfh34ksdu.com) are utilized by malware or bots to evade detection. This is a hallmark of Domain Generation Algorithms (DGA)-based attacks. Palo Alto Networks firewalls with Advanced DNS Security use machine learning to detect such domains by analyzing the entropy (randomness) of DNS queries. High entropy values indicate the likelihood of a dynamically generated or malicious domain.

Why not "Polymorphic DNS" (Option B)?While polymorphic DNS refers to techniques that dynamically change DNS records to avoid detection, it is not specifically identified as an attack type mitigated by Advanced DNS Security in Palo Alto Networks documentation. The firewall focuses more on the behavior of DNS queries, such as detecting DGA domains or anomalous DNS traffic patterns.

Why not "CNAME cloaking" (Option C)?CNAME cloaking involves using CNAME records to redirect DNS queries to malicious or hidden domains. Although Palo Alto firewalls may detect and block malicious DNS redirections, the focus of Advanced DNS Security is primarily on identifying patterns of DNS abuse like DGA domains, tunneling, or high entropy queries.

Why not "DNS domain rebranding" (Option D)?DNS domain rebranding involves changing the domain names associated with malicious activity to evade detection. This is typically a tactic used for persistence but is not an example of a DNS attack type specifically addressed by Advanced DNS Security.

Advanced DNS Security focuses on dynamic, real-time identification of suspicious DNS patterns, such as high entropy domains, DNS tunneling, or protocol violations. High entropy DNS domains are directly tied to attack mechanisms like DGAs, making this the correct answer.
