Palo Alto Networks Security Operations Generalist : SecOps-Generalist

A global company is implementing granular control over SaaS application usage using Palo Alto Networks Strata NGFWs at branch offices and Prisma Access for remote users. They have configured decryption policies to inspect SSL/TLS traffic for sanctioned SaaS applications like Office 365 and Salesforce. However, users accessing unsanctioned shadow IT applications via encrypted channels are still successfully bypassing security controls. Additionally, some legitimate applications are experiencing functionality issues after decryption is enabled. What are potential reasons for these issues and necessary steps to address them?

• A. The security policy rules using App-ID are ordered incorrectly, allowing 'allow' rules for 'any' application to match encrypted traffic before the decryption policy is evaluated.
• B. Application functionality issues may arise if the application uses client-side certificates, pinned certificates, or relies on specific SSL/TLS negotiation steps that are disrupted by the decryption proxy.
• C. Decryption is not properly configured for all relevant traffic zones, causing some encrypted traffic to pass through uninspected.
• D. The applications identified by App-ID are not all being processed by the decryption policy before reaching security profiles.
• E. The firewall/Prisma Access might be encountering SSL/TLS protocol versions or cipher suites that are not supported for decryption, leading to decryption failures and fallback to non-decrypted paths (potentially allowing unsanctioned apps).

When configuring Security Policy rules in Prisma Access for remote users, what are some key advantages of using User-ID (mapped to Active Directory groups) and App-ID compared to traditional firewall policies based solely on IP addresses, ports, and security zones?

• A. Improved performance by allowing the firewall to bypass deep packet inspection for trusted users and applications.
• B. Enhanced security posture by allowing policies to be defined based on 'who is doing what', rather than just 'where the traffic is going'.
• C. Granular control based on user identity (e.g., allow Finance users to access Finance app) and application identity (e.g., allow only specific collaboration tools), independent of IP addresses or ports.
• D. Reduced administrative overhead by eliminating the need for security zones or NAT policies.
• E. Consistent policy enforcement for users regardless of their changing IP address (e.g., when moving between locations or getting a new DHCP lease).

An organization relies on Palo Alto Networks NGFWs (PA-Series and VM-Series) to protect against the latest threats. Which dynamic updates are MOST critical for ensuring these firewalls have the most current information to identify applications, detect known malware and vulnerabilities, and identify malicious websites?

• A. URL Filtering updates
• B. Threat Prevention updates (Antivirus, Vulnerability Protection, Anti-Spyware signatures)
• C. App-ID updates
• D. WildFire updates
• E. PAN-OS software updates

A network administrator is configuring outbound internet access for an internal subnet (192.168.20.0/24) on a Palo Alto Networks Strata NGFW. They are using Dynamic IP and Port (DIPP) Source NAT (SNAT) to translate internal IPs to a single public IP (203.0.113.10) on the firewall's internet-facing interface. The NAT policy rule is configured as follows:

After this NAT rule is successfully matched, the firewall proceeds to evaluate Security Policy rules. When creating the Security Policy rule to allow this outbound internet traffic, what combination of Source Address and Destination Address should MOST logically be used in the Security Policy rule to match the traffic flow after the NAT rule is applied and determined?

• A. Source Address: 203.0.113.10, Destination Address: any
• B. Source Address: 192.168.20.0/24, Destination Address: 203.0.113.10
• C. Source Address: any, Destination Address: any
• D. Source Address: any, Destination Address: 203.0.113.10
• E. Source Address: 192.168.20.0/24, Destination Address: any

A branch office has a Prisma SD-WAN ION device deployed. The internal network is segmented into a 'Corporate' VLAN (employees) and a 'Guest-WIFI' VLAN (visitors). Both VLANs are configured on interfaces connected to the ION device. The security requirement is to allow Corporate users full internet access with deep security inspection but only allow Guest users basic web browsing and email, with stricter content filtering. How are Security Zones used on the Prisma SD-WAN ION to enforce these differing access policies between the internal segments and the internet?

• A. Security Zones are defined in the cloud management console but don't map directly to interfaces on the ION device.
• B. Each internal VLAN interface is assigned to a different Security Zone (e.g., 'Corporate-Zone', 'Guest-Zone'), and separate Security Policy rules are created from each internal zone to the 'Internet' zone with different application and URL filtering profiles.
• C. Security Zones are not used on ION devices; policy is applied based on VLAN IDs directly.
• D. All internal VLAN interfaces are assigned to a single 'Internal' zone, and policy differentiation is solely based on user groups via User-ID.
• E. Zones are used for traffic steering (Path Policy) but not for security policy enforcement.
