To preventSYN flood attacks, the NGFW usesSYN cookiesto 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.

To create custom Prisma Access reports withinSCM, you first configure adashboardthat aggregates the relevant logs and analytics. This allows you to define the data points you want to include.

“Dashboards in SCM can be customized to include Prisma Access data sources, enabling you to create and generate reports that meet specific business and security requirements.”

(Source: SCM Dashboards and Reporting)

Once configured, you can export the dashboard as acustom report.

“Use the dashboard’s data visualization to create custom reports for Prisma Access, which can be exported as PDFs for distribution.”

To fully leverageinline cloud analysisin Advanced Threat Prevention, security profiles (e.g., anti-spyware) must beupdated or newly createdto enable local deep learning and inline cloud analysis models.

“To activate inline cloud analysis, update your Anti-Spyware profile to enable advanced inline detection engines, including deep learning-based models and cloud-delivered signatures.”

(Source: Inline Cloud Analysis and Deep Learning)

This ensuresreal-time protectionfrom sophisticated threats beyond static signatures.

TheAnti-spyware profileincludes 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.”

Dynamic path selectionis 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.

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.”

When migrating from aperpetual VM-Series firewall license to a flexible VM licensing model, two critical steps are needed:

Allocate same number of vCPUs– This ensures that the VM-Series capacity remains consistent and avoids resource bottlenecks.

“When migrating perpetual VM-Series licenses to flexible VM licensing, allocate the same vCPU and memory resources to ensure equivalent performance.”

(Source: VM-Series Flexible Licensing Migration)

Limit to same security services– Flexible licensing requires maintaining the same security services to preserve licensing compliance.

“Ensure that you allow only the same security services on the flexible VM instance as were licensed on the perpetual VM.”

For large lists of specific URLs, creating acustom URL categoryand 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.”

(Source: Custom URL Categories)

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