Dynamic path selection is the foundation of SD-WAN, leveraging real-time performance data to dynamically route traffic over the best available path.

“Dynamic path selection continuously monitors performance metrics (loss, latency, jitter) and makes real-time routing decisions to ensure application SLAs are met across the WAN.”

(Source: Prisma SD-WAN Dynamic Path Selection)

Establishing dynamic path selection first ensures the rest of the SD-WAN optimizations (e.g., failover, QoS) work effectively.

The Anti-spyware profile includes DNS-based protections like sinkholing and detection of DNS queries to malicious domains, offering real-time protection against attacks that exploit DNS misconfigurations.

“The Anti-Spyware profile protects against DNS-based threats by sinkholing DNS queries to malicious domains and detecting suspicious DNS activity, thus blocking data exfiltration and C2 communication.”

GlobalProtect logs

These logs provide detailed insights into the user’s connectivity, tunnel status, and authentication events.

“GlobalProtect logs include detailed information about connection establishment, tunnel negotiation, and any errors that can prevent mobile users from accessing applications.”

Autonomous Digital Experience Management (ADEM)

ADEM helps visualize end-to-end performance and identifies network issues affecting SaaS app access for mobile users.

“ADEM provides real-time and historical visibility into user experience, enabling quick identification and resolution of connectivity or performance issues for SaaS applications.”

A centralized certificate automation approach reduces management overhead and security risks by standardizing processes, automating renewals, and continuously monitoring the certificate lifecycle.

“Implementing a centralized certificate management approach with automation and continuous monitoring ensures optimal security while reducing operational complexity in hybrid environments.”

For large lists of specific URLs, creating a custom URL category and importing the list is the most efficient approach for granular URL filtering.

“You can create custom URL categories to define specific URLs or patterns and enforce policies for these categories. This is the most efficient way to handle large sets of URLs.”

This approach saves time compared to manual rule creation or using generic application filters.

The Strata Logging Service offers scalable log storage to accommodate data growth, which ensures organizations can retain logs for compliance and threat hunting as their environments expand.

“The Strata Logging Service is designed to scale dynamically to accommodate growing log retention needs, allowing enterprises to maintain comprehensive visibility as they expand their network footprint.”

Palo Alto Networks' Enterprise DLP uses a centralized DLP profile that can be applied consistently across both Prisma Access and NGFWs using Strata Cloud Manager (SCM). This eliminates the need for duplicating efforts across multiple locations.

“Enterprise DLP profiles are created and managed centrally through the Cloud Management Interface and can be used seamlessly across NGFW and Prisma Access deployments.”

To prevent SYN flood attacks , the NGFW uses SYN cookies to validate legitimate session establishment.

“SYN cookies allow the firewall to verify the legitimacy of new session requests without allocating resources until the handshake is completed. This prevents SYN flood attacks from exhausting system resources.”

(Source: Flood Protection Best Practices)

SYN cookies mitigate resource exhaustion by ensuring only legitimate connections are established.

CASB integration should focus on comprehensive data protection, which includes encryption for data-at-rest and in transit , frequent key updates , and using strong encryption algorithms to ensure confidentiality and data integrity.

“CASB solutions should enforce encryption for data-at-rest and in transit, implement key rotation policies, and leverage robust encryption algorithms to protect sensitive SaaS application data.”
