Exam PSE-Strata-Pro-24 Topic 1 Question 28 Discussion

North-south traffic refers to the flow of data in and out of a network, typically between internal resources and the internet. To secure this type of traffic, Palo Alto Networks recommends specific CDSS subscriptions in addition to DNS Security:
A: SaaS Security
SaaS Security is designed for monitoring and securing SaaS application usage but is not essential for handling typical north-south traffic.
B: Advanced WildFire
Advanced WildFire provides cloud-based malware analysis and sandboxing to detect and block zero-day threats. It is a critical component for securing north-south traffic against advanced malware.
C: Enterprise DLP
Enterprise DLP focuses on data loss prevention, primarily for protecting sensitive data. While important, it is not a minimum recommendation for securing north-south traffic.
D: Advanced Threat Prevention
Advanced Threat Prevention (ATP) replaces traditional IPS and provides inline detection and prevention of evasive threats in north-south traffic. It is a crucial recommendation for protecting against sophisticated threats.
E: Advanced URL Filtering
Advanced URL Filtering prevents access to malicious or harmful URLs. It complements DNS Security to provide comprehensive web protection for north-south traffic.
Key Takeaways:
* Advanced WildFire, Advanced Threat Prevention, and Advanced URL Filtering are minimum recommendations for NGFWs handling north-south traffic, alongside DNS Security.
* SaaS Security and Enterprise DLP, while valuable, are not minimum requirements for this use case.
