Paloalto Networks Network Security Administrator NetSec-Generalist Question # 3 Topic 1 Discussion

ABest Practice Assessment (BPA)evaluates firewall configurations against Palo Alto Networks' recommendedbest practices. In this case, theCloud-Delivered Security Services (CDSS)update settings do not align with best practices, as they are currently set toweekly updates, whichdelays threat prevention.

Applications and Threats – Update Daily

Regular updates ensure the firewalldetects and blocks the latest exploits, vulnerabilities, and malware.

Weekly updates aretoo slowand leave the network vulnerable to newly discovered attacks.

WildFire – Update Every Five Minutes

WildFire is Palo Alto Networks' cloud-based malware analysis engine, whichidentifies and mitigates new threats in near real-time.

Updating every five minutesensures that newly discovered malware signatures are applied quickly.

A weekly update would significantlydelaythreat response.

(B) Antivirus should be updated daily.

While frequent updates are recommended,Antivirus in Palo Alto firewalls is updated hourly by default(not daily).

(D) URL Filtering should be updated hourly.

URL Filtering databases are updated dynamically in the cloud, and do not require fixed hourly updates.

URL filtering effectiveness depends on cloud integration rather than frequent updates.

Firewall Deployment– Ensuring dynamic updates align with best practices enhances security.

Security Policies– Applications, Threats, and WildFire updates are critical for enforcing protection policies.

Threat Prevention & WildFire– Frequent updates reduce the window of exposure to new threats.

Panorama– Updates can be managed centrally for branch offices.

Zero Trust Architectures– Requires real-time threat intelligence updates.
