In anExplicit Proxy deploymentwhereno agentcan be used on the endpoint,SAML (Security Assertion Markup Language)is the supported authentication method formobile users.SAMLallows authentication via anIdentity Provider (IdP)without requiring an agent on the endpoint, making it ideal for web-based authentication incloud and remote access environments. It enablesSingle Sign-On (SSO)and secure authentication without direct integration withLDAP or Kerberos, which typically require an agent or local network presence.

When network routers appear multiple times with different IP addresses in IoT Security, it is likely because they have multiple interfaces with separate IPs. Merging these entries into a single device with multiple interfaces ensures that the system correctly identifies each router as a unique entity while maintaining visibility across all its interfaces. This approach prevents unnecessary duplicates, improves asset management, and enhances security monitoring.

In Prisma Access's default routing mode, the service connections establish BGP sessions with the customer premises equipment (CPE) in the data centers. To ensure traffic destined for mobile users in a specific region (e.g., North America) traverses the service connection in that same region, you need to control the route advertisements.

Filtering out the mobile user pool prefixes from the other region on each service connection achieves this by:

Preventing the data center in one region from learning the specific mobile user prefixes of the other region.For example, the North American service connection would filter out the mobile user pool prefixes allocated to European users.

Ensuring that when a data center needs to send traffic to a mobile user, it will only see and use the route advertised by the service connection in the appropriate geographical region.This forces the traffic to enter the Prisma Access infrastructure through the intended regional service connection.

Let's analyze why the other options are incorrect based on official documentation regarding default routing mode:

A. Configure BGP on the customer premises equipment (CPE) to prefer the assigned community string attribute on the mobile user prefixes in its respective Prisma Access region.While BGP communities can be used for influencing routing decisions, in the context ofdefault routing modeand ensuring regional traffic flow, relying solely on the CPE to prefer community strings might not be the most robust or direct method to guarantee traffic traverses the correct regional service connection. The service connection itself needs to control the advertisement of prefixes.

C. Configure BGP on the customer premises equipment (CPE) to prefer the MED attribute on the mobile user prefixes in its respective Prisma Access region.The BGP MED (Multi-Exit Discriminator) attribute is primarily used to influence the path selectionbetweenautonomous systems (AS) or within the same AS at different entry points. In this scenario, where serviceconnections are advertising prefixes, filtering at the source (service connection) is a more direct and reliable way to ensure regional traffic flow than relying on the MED attribute on the CPE.

D. Configure each service connection to prepend the BGP ASN five times for mobile user pool prefixes originating from the other region.BGP AS path prepending is a mechanism to make a path less desirable. While this could influence routing, it doesn't guarantee that traffic will always take the intended regional path. Filtering provides a more definitive control over which routes are advertised and learned.

Therefore, configuring each service connection to filter out the mobile user pool prefixes from the other region in the advertisements to the data center is the verified method to ensure traffic destined for mobile users traverses the service connection in the appropriate region when using Prisma Access in default routing mode.

Prisma Access applies security rules in a hierarchical order, where rules at higher levels take precedence over those at lower levels. If a more permissive rule is placed higher in the hierarchy, it may allow traffic before the restrictive Web Security rule is evaluated. To resolve this, the engineer shouldreorder the rules to ensure the restrictive Web Security rule is positioned higher in the hierarchyso it is applied before any broader or conflicting rules.

The error messages indicate that Prisma Access is encountering certificate issues while attempting to decrypt traffic to "google.com." This suggests that theserver has pinned certificates, meaning it does not allow man-in-the-middle (MITM) decryption by Prisma Access. Since pinned certificates prevent traffic decryption, a solution is tocreate a "do not decrypt" rule for the hostname "google.com."This will allow traffic to flow without triggering certificate errors while maintaining secure communication with Google's servers.

When configuringRemote Browser Isolation (RBI)inPrisma Access (Managed by Strata Cloud Manager)for mobile users, aURL access management profilemust be created with thesite access action set to "Isolate". This profile is thenapplied to a Security policyto enforce isolation for specific URLs. This ensures thatweb traffic to designated high-risk or untrusted sitesisredirected to a remote, secure browser instance, protecting endpoints from potential web-based threats.

InPrisma Access, configuring anotification profileallows engineers to receive alerts when IPSec tunnels experience downtime or instability. By definingspecific conditions for remote network IPSec tunnels, the notification profile ensures that the engineer is proactively informed abouttunnel failures, flapping, or degraded performance. This approach enables timely troubleshooting and minimizes disruptions for users relying on the IPSec tunnels.

Configuring a webhook allows the company to receive real-time notifications when Prisma Access changes its egress IP addresses, ensuring that policy rules are updated automatically. Downloading a client certificate is necessary for authentication to the Egress IP API, allowing secure API access for retrieving updated IP addresses. These actions ensure that security policies remain effective without manual intervention.

TheCloud Dynamic User Groupcapability inCloud Identity Engineenables the creation ofSecurity policiesthat useEntra ID (formerly Azure AD) attributesfor user identification. This allows PrismaAccess to dynamically applyuser-based security rulesbased onreal-time Entra ID attributes, ensuring that access policies adapt to user changes such asgroup membership, device compliance, or role updates.

Ensuring that theRemote_Network_Templateis selected when adding the User-ID Agent in Panorama is crucial because User-ID information must be associated with the correctRemote Networkconfiguration for policies to apply properly. Additionally, theService_Conn_Templatemust be selected when adding the User-ID Agent in Panorama, as theservice connectionis responsible for distributing User-ID mappings between theon-premises firewall and Prisma Access. If either of these configurations is incorrect, the user information will not be properly mapped, and traffic will not match user-based policies.

When multitenancy is enabled in Prisma Access (Managed by Panorama), a key characteristic is the isolation of resources between tenants. Palo Alto Networks documentation emphasizes that each tenant operates within its own logically separate Prisma Access environment. This includes dedicated compute instances, ensuring that the performance and security of one tenant are not impacted by the activities of another.

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

A. Service connection licenses will be assigned only to the first tenant, and these service connections can be shared with the other tenants. This statement is incorrect. In a multitenant Prisma Access deployment, licenses are typically managed and allocated per tenant. While the underlying infrastructure might be shared by Palo Alto Networks, the logical resources and often the licensing are segmented for each tenant. Sharing service connections across completely separate tenants would violate the principle of tenant isolation.  

B. A single tenant cannot consist solely of mobile users or solely of remote networks. This statement is incorrect. Prisma Access multitenancy allows for flexibility in how tenants are configured. A tenant can be designed to exclusively serve mobile users, exclusively connect remote networks, or a combination of both, depending on the organizational structure and requirements.  

D. There is flexibility to manage different tenants using separate Panoramas, which allows for better organization and management of the multiple tenants. While it is possible to have multiple Panorama instances managing different parts of a large infrastructure, when discussing multitenancy within a single Prisma Access instance (as implied by the question "enabling multitenancy in Prisma Access (Managed by Panorama))", all configured tenants are managed by that single Panorama instance. Managing different tenants with separate Panoramas is a different architectural consideration, not a defining characteristic of enabling multitenancy within one Prisma Access deployment managed by a specific Panorama.

Therefore, the defining characteristic of Prisma Access multitenancy (Managed by Panorama) is the allocation of dedicated Prisma Access instances and compute resources for each tenant, ensuring logical separation and resource isolation

InPrisma Access, security policies are evaluated based on theirconfiguration scope. If the engineer configured aSecurity policyunder theRemote Networks scope, but traffic from the branch locations is instead matching aSecurity policy under the Prisma Access configuration scope, the intended policy will not take effect. This happens becausePrisma Access evaluates security rules based on the highest-level applicable configuration first, which can override more specific Remote Networks policies.

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 successfully creating aSAML authentication type and authentication profileinCloud Identity Engine, the next step is toconfigure a corresponding SAML authentication profile in Strata Cloud Managerand link it to theCloud Identity Engine profile. This ensures thatPrisma Access (Managed by Strata Cloud Manager)can authenticate mobile users using the configured SAML identity provider (IdP), enabling seamless user authentication and access control.

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.
