By usingsecurity checks under posture settingsinStrata Cloud Manager (SCM), the senior engineer can enforcepolicy compliance standardsbyautomatically denyingany security policy that does notalign with best practices. This ensures that junior engineers can create policies while preventing configurations that might introduce security gaps. This proactive approacheliminates manual oversightand enforces compliance at the time of policy creation, reducing risk and ensuring consistent security enforcement.

User mapping learned from sources other thangateway authenticationcan cause intermittent access issues if it conflicts with the expected user identity used in HIP-based policies. If the firewall is associatingthe user with an outdated or incorrect mapping, traffic may not match the intended security policies, leading todenials by the Catch-All Deny rule.

If thefirewall loses user mapping due to missed HIP report checks, the user may temporarily lose access to policies that require a validHost Information Profile (HIP)match. When the VPN connection is refreshed, the HIP check is re-initiated, restoring access until the issue repeats.

TheBGP peernot coming up despite anestablished IPSec tunnelindicates a potentialBGP configuration issue.

Secret– IfMD5 authenticationis configured for BGP, both Prisma Access and theCustomer Premises Equipment (CPE)must have thesame secret (authentication key). A mismatch will prevent BGP from establishing a session.

Peer AS Number– TheAutonomous System (AS) numberof the BGP peer must match what is expected on both sides of the connection. If the AS number is incorrect, the BGP session will fail to establish.

By verifying these elements, the engineer can troubleshoot and establish a successfulBGP peering sessionover theIPSec tunnel.

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 a large branch office experiences a high volume of employees logging in within a short time frame, the following apply:

Maximum pending TCP DNS requests is 64– This means that Prisma Access can queue up to 64 pending DNS requests over TCP before dropping additional requests. If more requests are received simultaneously, some may fail or experience delays.

Maximum number of TCP DNS retries is 3– If a DNS request fails over TCP, Prisma Access will attempt to retry the request up to three times before failing over to another method or returning an error.

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.

When onboarding toPrisma Access, usingDedicated IP addresseshelps address concerns about the time required to updateSaaS-allowed IP lists. Withdedicated egress IPs, the customer receivesfixed, predictable IP addressesthat do not change dynamically. This eliminates the need to frequently updateSaaS providers' allowlists, ensuring seamless access to cloud applications without interruptions due to IP address changes.

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 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.
