SSE-Engineer Questions and Answers

Embargo rules inPrisma Accessare designed toblock traffic from specific countriesthat are subject to regulatory or policy-based restrictions. These rules help organizations enforce compliance bypreventing inbound and outbound connectionsto or from regions that may pose security risks or arerestricted due to legal or geopolitical reasons. They are commonly used toalign with government sanctions and corporate security policies.

For complete data visibility inPrisma Access (Managed by Panorama),log forwarding profilesmust be applied toall security policiesto ensure that traffic logs are correctly sent toStrata Logging Service. If log forwarding is missing or misconfigured, some traffic data may not appear in theApplication Command Center (ACC), leading to incomplete insights. Verifying and correctly assigning log forwarding ensures that all relevant network activity is captured and available for analysis.

When terminating aPartner Interconnect-based Colo-ConnectinPrisma Access, theCustomer Premises Equipment (CPE)must supportIPSecas the overlay protocol. Prisma Access establishes secureIPSec tunnelsbetween theColo-Connect infrastructure and the CPE, ensuringencrypted communicationand reliable connectivity.IPSecprovidessecure site-to-cloud integration, enabling customers to extend their private network securely over the Prisma Access infrastructure.

When the "Overlapping Subnets" checkbox is selected during the Remote Network onboarding process in Prisma Access, the deployment enables Private Application access using Prisma Access for Users(ZTNA or Private Access). This feature is designed to handle scenarios where multiple sites use the same IP subnet by leveraging NAT (Network Address Translation) and segmentation to avoid conflicts.

Since overlapping subnets can create routing challenges for direct remote network-to-remote network communication, Prisma Access does not support Remote Network-to-Remote Network or Mobile User communication in this case. Private application access is supported as Prisma Access correctly routes requests based on application-layer intelligence rather than IP-based routing.

Palo Alto Networks documentation clearly states that when configuring the traffic replication feature in Prisma Access, you mustspecify an internal security applianceas the destination for the mirrored traffic. This appliance, typically a Palo Alto Networks next-generation firewall or a third-party security tool, is responsible for receiving and analyzing the replicated traffic for various purposes like threat analysis, troubleshooting, or compliance monitoring.

Let's analyze why the other options are incorrect based on official documentation:

B. Dedicated cloud storage location:While Prisma Access logs and other data might be stored in the cloud, themirrored trafficfor real-time analysis is directly streamed to a designated security appliance, not a passive storage location.

C. Panorama:Panorama is the centralized management system for Palo Alto Networks firewalls. While Panorama can receive logs and manage the configuration of Prisma Access, it is not the direct destination for real-time mirrored traffic intended for immediate analysis.  

D. Strata Cloud Manager (SCM):Strata Cloud Manager is the platform used to configure and manage Prisma Access. It facilitates the setup of traffic replication, including specifying the destination appliance, but it does not directly receive or analyze the mirrored traffic itself.  

Therefore, the mirrored traffic from the traffic replication feature in Prisma Access is directed to a specified internal security appliance for analysis.

To meet the customer’s requirements,GlobalProtect and Remote Networksshould be used as follows:

GlobalProtect: This enables secure access for mobile users, ensuring internet filtering, data center connectivity, and access to branch locations.

Remote Networks: This is used to provide security and connectivity for branch locations, ensuring internet filtering and data center access.

Service Connections: These allow both mobile users and branch locations to securely connect to the data center for internal resources.

This configuration ensures that mobile users and branch locations can securely access the internet while maintaining asegregated and secureconnection to internal resources. It also aligns with Prisma Access's best practices forsecurity enforcement, traffic filtering, and centralized management.

After configuringdomain-based split tunnelingforzoom.us, the expected behavior can be confirmed by checking therouting table on the client machine. If split tunneling is correctly configured, the traffic forzoom.usshould be routedoutsidethe GlobalProtect VPN tunnel, while other traffic follows the tunnel path. Reviewing the routing table ensures thatonly the intended traffic is excluded from the tunnel, confirming that the split tunnel configuration is working as expected.

To meet the customer’s requirements, two separate Prisma Access instances should be deployed:

Instance 1should includemobile users, remote networks, and private accessfor internal connectivity. This ensures that mobile users can access the internet, data centers, and remote branch locations while enforcing security policies.

Instance 2should be configured withremote networks and private application accessfor B2B connections. This instance will restrict access to only the required internally developed applications using non-standard ports, ensuring that partners cannot access other corporate resources.

By usingspecific configuration scopes for different connection types, the security team can manage access to mobile users and branch locations, while the network team can manage B2B partner connections. This ensuresproper segmentation of management responsibilitieswhile maintaining security and compliance.

TheStrata Logging Serviceallowslog replay, which enables resending logs that were not successfully forwarded to an external syslog server due to disruptions. By configuring areplay profilewith the affected time range and associating it with thesyslog server profile, Prisma Access will resend the missing logs, ensuring that all relevant data is restored in the external logging system. This approach is the most efficient and automated way to recover missing logs.

The"400 Bad Request"error when attemptingSAML authenticationthrough theCloud Identity Engine (CIE)suggests amisconfiguration in the SAML metadata. This typically occurs when theendpoint URLs, certificates, or entity IDsdo not match betweenCloud Identity Engine and the IdP portal. To resolve this, verify that:

TheSAML metadatauploaded toCloud Identity Enginematches theconfiguration from the IdP.

TheACS (Assertion Consumer Service) URL, Entity ID, and certificateare correctly set.

There are no incorrect or expired certificates in theCloud Identity Engine and IdP configuration.

By ensuring theSAML metadatais properly configured inboth systems, authentication should proceed without errors.
