Network Security Administrator PCNSA Syllabus Exam Questions Answers

To see how new and modified App-IDs impact your Security policy, you need to follow the path Device > Dynamic Updates > Review App-IDs on PAN-OS 11.x. This option allows you to perform a content update policy review for both downloaded and installed content. You can view the list of new and modified App-IDs and their descriptions, and see which Security policy rules are affected by them. You can also modify the rules or create new ones to adjust your Security policy as needed1. References: See How New and Modified App-IDs Impact Your Security Policy, Updated Certifications for PAN-OS 10.1, Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0) or [Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0)].

Palo Alto Networks firewalls can map IP addresses to usernames using various methods, such as User-ID agents, Captive Portal, GlobalProtect, XML API, and HTTP headers. These methods allow the firewall to enforce security policies based on user identity, rather than just IP address. Some of these methods are:

• Using the XML API: The XML API allows external systems to send user mapping information to the firewall using HTTPS requests. The firewall can then use this information to identify the users behind the IP addresses and apply the appropriate policies1.
• A user connecting into a GlobalProtect gateway using a GlobalProtect Agent: GlobalProtect provides secure remote access to the network by establishing a VPN tunnel between the user’s device and the firewall. When a user connects to a GlobalProtect gateway using a GlobalProtect agent, the firewall can authenticate the user and map the user’s IP address to the username1.
• Usernames inserted inside HTTP Headers: The firewall can also extract usernames from HTTP headers in web traffic. This method requires the web server or proxy server to insert the username into a custom HTTP header that the firewall can read. The firewall can then use this information to map the IP address to the username1.
