PCNSE PCNSE Advanced Threat Prevention 5 — Questions and Answers
Question 1: Which Advanced Threat Prevention capability specifically protects against injection-based attacks within web application traffic by analyzing HTTP request patterns?
- WildFire sandboxing
- Vulnerability Protection signatures for web attacks (e.g., SQLi, XSS) (Correct answer)
- Anti-Spyware DNS sinkholing
- File Blocking with custom MIME types
Correct answer: Vulnerability Protection signatures for web attacks (e.g., SQLi, XSS)
Vulnerability Protection profiles include signatures that detect and block common web attack patterns like SQL injection and cross-site scripting in HTTP traffic.
Question 2: An organization uses PAN-OS Zone Protection profiles. Which threat protection setting within a Zone Protection profile helps mitigate reconnaissance activity?
- Antivirus scanning
- Reconnaissance Protection (port scan and host sweep detection) (Correct answer)
- WildFire file forwarding
- URL filtering category enforcement
Correct answer: Reconnaissance Protection (port scan and host sweep detection)
Zone Protection profiles include Reconnaissance Protection that detects and blocks TCP/UDP port scans and host sweep attempts before they reach security policies.
Question 3: What is the significance of the 'threat-id' field in a PAN-OS threat log entry?
- It identifies the firewall that generated the log
- It uniquely identifies the specific threat signature that triggered the log entry (Correct answer)
- It specifies the destination IP address of the threat actor
- It indicates the WildFire verdict assigned to the traffic
Correct answer: It uniquely identifies the specific threat signature that triggered the log entry
The threat-id is a unique identifier for the specific Palo Alto Networks threat signature that matched the traffic, enabling precise lookup in threat databases.
Question 4: A firewall is deployed in tap mode. Which Threat Prevention actions will be enforced on matched traffic?
- All configured actions including block and reset
- Only 'Alert' and 'Allow' — tap mode cannot block traffic (Correct answer)
- Only WildFire submissions; all other actions are skipped
- Drop and reset actions only, not alert
Correct answer: Only 'Alert' and 'Allow' — tap mode cannot block traffic
In tap mode, the firewall receives a copy of traffic and cannot inject packets to block or reset connections, so only passive actions like alerting are effective.
Question 5: Which setting in a WildFire Analysis profile controls which file types are forwarded to WildFire for analysis?
- File Blocking profile MIME type list
- Application and file type selections within the WildFire Analysis profile (Correct answer)
- Antivirus profile decoder settings
- Security policy application filter
Correct answer: Application and file type selections within the WildFire Analysis profile
The WildFire Analysis profile specifies application and file type combinations (e.g., PE files over FTP, PDFs over SMTP) that the firewall forwards to WildFire.
Question 6: What is the primary purpose of the 'botnet report' available under Monitor in PAN-OS?
- It lists all URL filtering policy matches from the past 24 hours
- It identifies internal hosts exhibiting botnet-like behavior such as C2 communication and IRC traffic (Correct answer)
- It shows WildFire analysis results for PE files
- It generates a compliance report for PCI-DSS auditors
Correct answer: It identifies internal hosts exhibiting botnet-like behavior such as C2 communication and IRC traffic
The Botnet Report analyzes traffic logs to identify internal hosts showing behavioral indicators of botnet infection, such as repeated C2 beaconing or unusual IRC connections.
Question 7: When a Palo Alto Networks firewall detects an exploit attempt that matches a Vulnerability Protection signature with action 'Block-IP,' what additional configuration is required for the block to take effect?
- A separate DoS Protection policy must reference the same zone
- The 'Track-By' option and block duration must be configured within the Block-IP action settings (Correct answer)
- An EDL (External Dynamic List) must include the attacker's IP
- A Security policy with application 'threat' must exist
Correct answer: The 'Track-By' option and block duration must be configured within the Block-IP action settings
The Block-IP action requires configuring whether to track by source, destination, or both, along with the duration for which the IP will be blocked.
