SSE-Engineer Sample Questions Answers

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.

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.

SaaS Security Inline allows engineers to customize the risk scores assigned to different SaaS applications based on various factors. By manipulating these risk scores, you can influence how these applications are treated within Security policies.

To limit the use of unsanctioned SaaS applications:

Lower the risk score of sanctioned applications:This makes them less likely to trigger policies designed to restrict high-risk activities.

Increase the risk score of unsanctioned applications:This elevates their perceived risk, making them more likely to be caught by Security policies configured to block or limit access based on risk score thresholds.

Then, you would create Security policies that take action (e.g., block access, restrict features) based on these adjusted risk scores. For example, a policy could be configured to block access to any SaaS application with a risk score above a certain threshold, which would primarily target the unsanctioned applications with their inflated scores.

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

B. Increase the risk score for all SaaS applications to automatically block unwanted applications.Increasing the risk score forallSaaS applications, including sanctioned ones, would lead to unintended blocking and disruption of legitimate business activities. Risk score customization is intended for differentiation, not a blanket increase.

C. Build an application filter using unsanctioned SaaS as the category.While creating an application filter based on the "unsanctioned SaaS" category is a valid way to identify these applications, it directly filters based on the category itself, not the risk score. Risk score customization provides a more nuanced approach where you can define thresholds and potentially allow some low-risk activities within unsanctioned applications while blocking higher-risk ones.

D. Build an application filter using unsanctioned SaaS as the characteristic.Similar to option C, using "unsanctioned SaaS" as a characteristic in an application filter allows you to directly target these applications. However, it doesn't leverage the risk score customization feature to control access based on a graduated level of risk.

Therefore, the most effective way to use risk score customization to limit unsanctioned SaaS application usage is by lowering the risk scores of sanctioned applications and increasing the risk scores of unsanctioned ones, and then building Security policies that act upon these adjusted risk scores.

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.

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.

Service connections enable secure connectivity between Prisma Access and on-premises data centers, allowing mobile users and branch locations to access internal applications. They facilitate seamless integration of internal networks with Prisma Access while maintaining security policies. Colo-Connect provides a dedicated and optimized pathway for traffic between Prisma Access and data centers, ensuring stable performance and reduced latency over the internet. Both components together support secure and efficient data center connectivity while aligning with the customer's access control and filtering requirements.

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.

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 amultitenant deployment, access control must be configured at theChild Tenantlevel to ensure that security administrators have full control over Security policyonly within their assigned tenantwhile restricting access to other tenants. By selectingPrisma Access & NGFW Configuration, the assigned users gain full administrative accessonly for security policy managementwithin the designated tenant, aligning with RBAC best practices for controlled access inPrisma Access Managed by Strata Cloud Manager.

Updating theCloud Services plugininPrisma Accessdoes not disrupt existing traffic flows because the upgrade process is designed to beseamless and transparent. Prisma Access ensures high availability by maintainingactive sessions and policieswhile applying the update in the background. This allows ongoing connections to continue without interruptions, minimizing impact on user experience.

In aPanorama Managed Prisma Access multitenant environment,Access Domainsprovide granularrole-based access control (RBAC). By defining anAccess Domain, the network security team can be granted full administrative privileges for aspecific tenant's configurationwhile ensuring theycannot access or modify other tenants. This method enforces proper segmentation andensures compliance with multitenant security policies.

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.
