Exam NetSec-Generalist Topic 4 Question 17 Discussion

Prisma Access, a cloud-delivered security platform by Palo Alto Networks, supports specific predefined zones to streamline policy creation and enforcement. These zones are integral to how traffic is managed and secured within the service.
Available Zones in Prisma Access:
Trust Zone:
This zone encompasses all trusted and onboarded IP addresses, service connections, or mobile users within the corporate network. Traffic originating from these entities is considered trusted.
Untrust Zone:
This zone includes all untrusted IP addresses, service connections, or mobile users outside the corporate network. By default, any IP address or mobile user that is not designated as trusted falls into this category.
Clientless VPN Zone:
Designed to provide secure remote access to common enterprise web applications that utilize HTML, HTML5, and JavaScript technologies. This feature allows users to securely access applications from SSL-enabled web browsers without the need to install client software, which is particularly useful for enabling partner or contractor access to applications and for safely accommodating unmanaged assets, including personal devices. Notably, the Clientless VPN zone is mapped to the trust zone by default, and this setting cannot be changed.
Analysis of Options:
A . DMZ:
A Demilitarized Zone (DMZ) is a physical or logical subnetwork that separates an internal local area network (LAN) from other untrusted networks, typically the internet. While traditional network architectures often employ a DMZ to add an extra layer of security, Prisma Access does not specifically define or utilize a DMZ zone within its predefined zone structure.
B . Interzone:
In the context of Prisma Access, "interzone" is not a predefined zone available for user configuration. However, it's worth noting that Prisma Access logs may display a zone labeled "inter-fw," which pertains to internal communication within the Prisma Access infrastructure and is not intended for user-defined policy application.
C . Intrazone:
Intrazone typically refers to traffic within the same zone. While security policies can be configured to allow or deny intrazone traffic, "Intrazone" itself is not a standalone zone available for configuration in Prisma Access.
D . Clientless VPN:
As detailed above, the Clientless VPN is a predefined zone in Prisma Access, designed to facilitate secure, clientless access to web applications.
Conclusion:
Among the options provided, D. Clientless VPN is the correct answer, as it is an available predefined zone in Prisma Access.
