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

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.

User-ID Best Practices:

The appropriate CDSS subscription to inspect and mitigate suspicious DNS traffic isAdvanced DNS Security. Here’s why:

Advanced DNS Securityprotects against DNS-based threats, including domain generation algorithms (DGA), DNS tunneling (often used for data exfiltration), and malicious domains used in attacks. It leverages machine learning to detect and block DNS traffic associated with command-and-control servers or other malicious activities. In this case, unusually high DNS traffic to an unfamiliar IP address is likely indicative of a DNS-based attack or malware activity, making this the most suitable service.

Option A:Advanced Threat Prevention (ATP) focuses on identifying and blocking sophisticated threats in network traffic, such as exploits and evasive malware. While it complements DNS Security, it does not specialize in analyzing DNS-specific traffic patterns.

Option B:Advanced WildFire focuses on detecting and preventing file-based threats, such as malware delivered via email attachments or web downloads. It does not provide specific protection for DNS-related anomalies.

Option C:Advanced URL Filtering is designed to prevent access to malicious or inappropriate websites based on their URLs. While DNS may be indirectly involved in resolving malicious websites, this service does not directly inspect DNS traffic patterns for threats.

Option D (Correct):Advanced DNS Security specifically addresses DNS-based threats. By enabling this service, the customer can detect and block DNS queries to malicious domains and investigate anomalous DNS behavior like the high traffic observed in this scenario.

How to Enable Advanced DNS Security:

Ensure the firewall has a valid Advanced DNS Security license.

Navigate toObjects > Security Profiles > Anti-Spyware.

Enable DNS Security under the "DNS Signatures" section.

Apply the Anti-Spyware profile to the relevant Security Policy to enforce DNS Security.

Best Practices for DNS Security Configuration.

Strata Cloud Manager (SCM), part of Palo Alto Networks’ Prisma Access and Prisma SD-WAN suite, provides enhanced visibility and control for managing compliance and security policies across the network. In the Premium version of SCM, compliance frameworks are pre-integrated to help organizations streamline audits and maintain adherence to critical standards.

A. Payment Card Industry (PCI)

PCI DSS (Data Security Standard) compliance is essential for businesses that handle payment card data. SCM Premium provides monitoring, reporting, and auditing tools that align with PCI requirements, ensuring that sensitive payment data is processed securely across the network.

B. National Institute of Standards and Technology (NIST)

NIST is a comprehensive cybersecurity framework used in various industries, especially in the government sector. However, NIST is not specifically included in SCM Premium; organizationsmay need separate configurations or external tools to fully comply with NIST guidelines.

C. Center for Internet Security (CIS)

CIS benchmarks provide security best practices for securing IT systems and data. SCM Premium includes CIS compliance checks, enabling organizations to maintain a strong baseline security posture and proactively address vulnerabilities.

D. Health Insurance Portability and Accountability Act (HIPAA)

HIPAA is a framework designed to protect sensitive healthcare information. While Palo Alto Networks provides general solutions that can be aligned with HIPAA compliance, it is not explicitly included as a compliance framework in SCM Premium.

Key Takeaways:

The frameworks included in SCM Premium are PCI DSS and CIS.

Other frameworks like NIST and HIPAA may require additional configurations or are supported indirectly but not explicitly part of the Premium compliance checks.
