Paloalto Networks NetSec-Pro Exam With Confidence Using Practice Dumps

The firewall must be running a PAN-OS version that is supported by Panorama. This means that Panorama must be running the same or a newer PAN-OS version as the one being installed on the firewalls to maintain compatibility.

“Before you upgrade the firewall, ensure that Panorama is running the same or a later PAN-OS version than the firewall. Panorama must always be at the same or a higher version to maintain compatibility.”

When implementing SSL Forward Proxy decryption for outbound traffic, two key challenges that must be evaluated are:

Incomplete certificate chains : This occurs when the firewall cannot validate the entire certificate chain for a site, which may cause decryption failures.

Certificate pinning : Applications like banking apps may use certificate pinning to prevent MITM (man-in-the-middle) attacks, and these applications will break if SSL Forward Proxy is used.

“When decrypting outbound SSL traffic, you must consider incomplete certificate chains, which can cause decryption to fail if the firewall cannot validate the entire chain. Also, be aware of certificate pinning in applications that prevents decryption by rejecting forged certificates.”

Protecting against malicious and misconfigured domains requires two critical services:

Advanced Threat Prevention

Provides signature-based and advanced analysis to identify threats, including DNS-based attacks.

“Advanced Threat Prevention enables the NGFW to detect and prevent exploits and malware-based communications, including those leveraging DNS.”

Advanced DNS Security

Specifically designed to detect and sinkhole malicious and misconfigured DNS queries.

“DNS Security uses real-time intelligence to block DNS-based threats, protect against data exfiltration, and automatically sinkhole suspicious domain lookups.”

By combining these services in security policies, NGFWs ensure robust protection against domain-based threats and misconfigurations.
