A security engineer has been tasked with protecting a company's on-premises web servers but is not authorized to purchase a web application firewall (WAF).
Which Palo Alto Networks solution will protect the company from SQL injection zero-day, command injection zero-day, Cross-Site Scripting (XSS) attacks, and IIS exploits?
Threat Prevention and PAN-OS 11.x
Advanced Threat Prevention and PAN-OS 11.x
Threat Prevention, Advanced URL Filtering, and PAN-OS 10.2 (and higher)
Advanced WildFire and PAN-OS 10.0 (and higher)
Protecting web servers from advanced threats like SQL injection, command injection, XSS attacks, and IIS exploits requires a solution capable of deep packet inspection, behavioral analysis, andinline prevention of zero-day attacks. The most effective solution here isAdvanced Threat Prevention (ATP)combined withPAN-OS 11.x.
Why "Advanced Threat Prevention and PAN-OS 11.x" (Correct Answer B)?Advanced Threat Prevention (ATP) enhances traditional threat prevention by usinginline deep learning modelsto detect and block advanced zero-day threats, includingSQL injection, command injection, and XSS attacks. With PAN-OS 11.x, ATP extends its detection capabilities to detect unknown exploits without relying on signature-based methods. This functionality is critical for protecting web servers in scenarios where a dedicated WAF is unavailable.
ATP provides the following benefits:
Inline prevention of zero-day threats using deep learning models.
Real-time detection of attacks like SQL injection and XSS.
Enhanced protection for web server platforms like IIS.
Full integration with the Palo Alto Networks Next-Generation Firewall (NGFW).
Why not "Threat Prevention and PAN-OS 11.x" (Option A)?Threat Prevention relies primarily on signature-based detection for known threats. While it provides basic protection, it lacks the capability to block zero-day attacks using advanced methods like inline deep learning. For zero-day SQL injection and XSS attacks, Threat Prevention alone is insufficient.
Why not "Threat Prevention, Advanced URL Filtering, and PAN-OS 10.2 (and higher)" (Option C)?While this combination includes Advanced URL Filtering (useful for blocking malicious URLs associated with exploits), it still relies onThreat Prevention, which is signature-based. This combination does not provide the zero-day protection needed for advanced injection attacks or XSS vulnerabilities.
Why not "Advanced WildFire and PAN-OS 10.0 (and higher)" (Option D)?Advanced WildFire is focused on analyzing files and executables in a sandbox environment to identify malware. While it is excellent for identifying malware, it is not designed to provide inline prevention for web-based injection attacks or XSS exploits targeting web servers.
A systems engineer should create a profile that blocks which category to protect a customer from ransomware URLs by using Advanced URL Filtering?
Ransomware
High Risk
Scanning Activity
Command and Control
When configuring Advanced URL Filtering on a Palo Alto Networks firewall, the "Ransomware" category should be explicitly blocked to protect customers from URLs associated with ransomware activities. Ransomware URLs typically host malicious code or scripts designed to encrypt user data and demand a ransom. By blocking the "Ransomware" category, systems engineers can proactively prevent users from accessing such URLs.
Why "Ransomware" (Correct Answer A)?The "Ransomware" category is specifically curated by Palo Alto Networks to include URLs known to deliver ransomware or support ransomware operations. Blocking this category ensures that any URL categorized as part of this list will be inaccessible to end-users, significantly reducing the risk of ransomware attacks.
Why not "High Risk" (Option B)?While the "High Risk" category includes potentially malicious sites, it is broader and less targeted. It may not always block ransomware-specific URLs. "High Risk" includes a range of websites that are flagged based on factors like bad reputation or hosting malicious content in general. It is less focused than the "Ransomware" category.
Why not "Scanning Activity" (Option C)?The "Scanning Activity" category focuses on URLs used in vulnerability scans, automated probing, or reconnaissance by attackers. Although such activity could be a precursor to ransomware attacks, it does not directly block ransomware URLs.
Why not "Command and Control" (Option D)?The "Command and Control" category is designed to block URLs used by malware or compromised systems to communicate with their operators. While some ransomware may utilize command-and-control (C2) servers, blocking C2 URLs alone does not directly target ransomware URLs themselves.
By using the Advanced URL Filtering profile and blocking the "Ransomware" category, the firewall applies targeted controls to mitigate ransomware-specific threats.
While responding to a customer RFP, a systems engineer (SE) is presented the question, "How do PANW firewalls enable the mapping of transactions as part of Zero Trust principles?" Which two narratives can the SE use to respond to the question? (Choose two.)
Emphasize Zero Trust as an ideology, and that the customer decides how to align to Zero Trust principles.
Reinforce the importance of decryption and security protections to verify traffic that is not malicious.
Explain how the NGFW can be placed in the network so it has visibility into every traffic flow.
Describe how Palo Alto Networks NGFW Security policies are built by using users, applications, and data objects.
The question asks how Palo Alto Networks (PANW) Strata Hardware Firewalls enable the mapping of transactions as part of Zero Trust principles, requiring a systems engineer (SE) to provide two narratives for a customer RFP response. Zero Trust is a security model that assumes no trust by default, requiring continuous verification of all transactions, users, and devices—inside and outside the network. The Palo Alto Networks Next-Generation Firewall (NGFW), part of the Strataportfolio, supports this through its advanced visibility, decryption, and policy enforcement capabilities. Below is a detailed explanation of why options B and D are the correct narratives, verified against official Palo Alto Networks documentation.
Step 1: Understanding Zero Trust and Transaction Mapping in PAN-OS
Zero Trust principles, as defined by frameworks like NIST SP 800-207, emphasize identifying and verifying every transaction (e.g., network flows, application requests) based on context such as user identity, application, and data. For Palo Alto Networks NGFWs, "mapping of transactions" refers to the ability to identify, classify, and control network traffic with granular detail, enabling verification and enforcement aligned with Zero Trust.
The PAN-OS operating system achieves this through:
App-ID: Identifies applications regardless of port or protocol.
User-ID: Maps IP addresses to user identities.
Content-ID: Inspects and protects content, including decryption for visibility.
Security Policies: Enforces rules based on these mappings.
Which two statements correctly describe best practices for sizing a firewall deployment with decryption enabled? (Choose two.)
SSL decryption traffic amounts vary from network to network.
Large average transaction sizes consume more processing power to decrypt.
Perfect Forward Secrecy (PFS) ephemeral key exchange algorithms such as Diffie-Hellman Ephemeral (DHE) and Elliptic-Curve Diffie-Hellman Exchange (ECDHE) consume more processing resources than Rivest-Shamir-Adleman (RSA) algorithms.
Rivest-Shamir-Adleman (RSA) certificate authentication method (not the RSA key exchange algorithm) consumes more resources than Elliptic Curve Digital Signature Algorithm (ECDSA), but ECDSA is more secure.
When planning a firewall deployment with SSL/TLS decryption enabled, it is crucial to consider the additional processing overhead introduced by decrypting and inspecting encrypted traffic. Here are the details for each statement:
Why "SSL decryption traffic amounts vary from network to network" (Correct Answer A)?SSL decryption traffic varies depending on the organization’s specific network environment, user behavior, and applications. For example, networks with heavy web traffic, cloud applications, or encrypted VoIP traffic will have more SSL/TLS decryption processing requirements. This variability means each deployment must be properly assessed and sized accordingly.
Why "Perfect Forward Secrecy (PFS) ephemeral key exchange algorithms such as Diffie-Hellman Ephemeral (DHE) and Elliptic-Curve Diffie-Hellman Exchange (ECDHE) consume more processing resources than Rivest-Shamir-Adleman (RSA) algorithms" (Correct Answer C)?PFS algorithms like DHE and ECDHE generate unique session keys for each connection, ensuring better security but requiring significantly more processing power compared to RSA key exchange. When decryption is enabled, firewalls must handle these computationally expensive operations for every encrypted session, impacting performance and sizing requirements.
Why not "Large average transaction sizes consume more processing power to decrypt" (Option B)?While large transaction sizes can consume additional resources, SSL/TLS decryption is more dependent on the number of sessions and the complexity of the encryption algorithms used, rather than the size of the transactions. Hence, this is not a primary best practice consideration.
Why not "Rivest-Shamir-Adleman (RSA) certificate authentication method consumes more resources than Elliptic Curve Digital Signature Algorithm (ECDSA), but ECDSA is more secure" (Option D)?This statement discusses certificate authentication methods, not SSL/TLS decryption performance. While ECDSA is more efficient and secure than RSA, it is not directly relevant to sizing considerations for firewall deployments with decryption enabled.
