In Prisma Access, theinterzonesecurity policy rule isavailableand plays a crucial role in controlling trafficbetweenzones.

“You can configure an interzone rule to control traffic that flows between different zones in Prisma Access, enabling granular security policy enforcement.”

This ensures comprehensive control of traffic crossing security boundaries in the cloud-delivered architecture.

Protecting againstmaliciousandmisconfigured domainsrequires two critical services:

Advanced Threat Prevention

Provides signature-based and advanced analysis to identify threats, including DNS-based attacks.

“Advanced Threat Prevention enables the NGFW to detect and prevent exploits and malware-based communications, including those leveraging DNS.”

(Source: Advanced Threat Prevention)

Advanced DNS Security

Specifically designed to detect and sinkhole malicious and misconfigured DNS queries.

“DNS Security uses real-time intelligence to block DNS-based threats, protect against data exfiltration, and automatically sinkhole suspicious domain lookups.”

Bycombiningthese services in security policies, NGFWs ensure robust protection against domain-based threats and misconfigurations.

Threat logs for Prisma Access mobile users can be reviewed in bothStrata Cloud Manager (SCM)andStrata Logging Service. Prisma Cloud and service connection firewalls are not directly tied to mobile user traffic logs.

“Prisma Access logs are available in the Strata Cloud Manager and can also be sent to the Strata Logging Service for detailed analysis and threat visibility.”

Content-IDis the core of Palo Alto Networks' prevention architecture, providingsingle-pass application layer inspectionto deliver real-time threat prevention across all traffic.

“Content-ID uses a single-pass architecture to perform application-layer (Layer 7) traffic inspection and real-time threat prevention. Unlike traditional firewalls that rely on multiple scans, Content-ID inspects traffic once to enforce multiple security controls simultaneously.”

By consolidating security functions in a single pass, it ensures both efficiency and comprehensive security.

When usingAWS centralized deploymentsfor Cloud NGFW, the service deploys NGFW instances intoselected VPCsas additional workloads to secure that traffic.

“In centralized deployments, Cloud NGFW instances are deployed as security appliances within the selected VPCs, ensuring consistent traffic inspection and protection.”

This approach minimizes complexity and ensures direct security policy enforcement within AWS.

Enterprise DLPuses cloud analysis to inspect and classify sensitive data innon-file-based formats(e.g., in-line data streams, SaaS communications).

“Enterprise DLP inspects data in non-file-based traffic flows, forwarding suspicious data patterns to the cloud for classification and verdicts.”

(Source: Enterprise DLP Overview)

The other services focus on file-based scanning (WildFire), URL access control (Advanced URL Filtering), or inline SaaS application controls (SaaS Security Inline).

Adecryption policyallows the firewall to inspect encrypted traffic and apply security controls toPost-quantum Cryptography (PQC)usage, as PQC algorithms are typically implemented within encrypted sessions.

“Decryption policies enable the firewall to see and control encrypted traffic. This visibility and control extend to new cryptographic algorithms, including PQC, to ensure that security measures are applied consistently.”

(Source: Palo Alto Networks Decryption Overview)

By decrypting sessions, you ensure that even PQC traffic can be inspected, logged, and subject to security profiles for visibility and policy enforcement.

Negated source addressesexclude traffic from the specified region. To avoid accidental connectivity loss for trafficfrom that region, create a separate Security policy toexplicitly permit it.

“When you use a negated region in a Security policy rule, ensure to create an additional Security policy to permit traffic from the excluded (negated) region to avoid unintentional drops.”

(Source: Prisma Access Policy Best Practices)

This ensuresexplicit inclusivity for the excluded region, maintaining reliable connectivity.

Prisma Access for secure remote access

“Prisma Access extends consistent security and optimized connectivity to branch locations, enabling secure access for mobile and branch users.”

(Source: Prisma Access Overview)

Centralized management for consistent policy enforcement

“Centralized management using Strata Cloud Manager or Panorama ensures security policies and updates are uniformly applied across distributed locations, preventing policy drift and security gaps.”

(Source: Strata Cloud Manager Best Practices)

These two practices are foundational for modern, distributed enterprise networks to maintain security posture and performance.

For IoT Security toaccurately classify and monitorIoT devices, the following logs must be forwarded to Strata Logging Service:

Enhanced application logs– provide detailed application usage and behaviors, essential for profiling device types and roles.

“Enhanced Application logs provide additional context on IoT device behavior and usage patterns, and must be forwarded to Strata Logging Service for IoT Security to build accurate Device-ID profiles.”

(Source: IoT Security Logging Requirements)

Threat logs– essential for detecting suspicious or malicious activities by IoT devices.

“Threat logs are critical for identifying potential exploits or suspicious activities involving IoT devices and are required for accurate threat visibility within IoT Security.”

(Source: IoT Security Logs)

These logs collectively ensure accurate device classification and real-time threat visibility.
