A systems engineer (SE) is working with a customer that is fully cloud-deployed for all applications. The customer is interested in Palo Alto Networks NGFWs but describes the following challenges:
"Our apps are in AWS and Azure, with whom we have contracts and minimum-revenue guarantees. We would use the built-in firewall on the cloud service providers (CSPs), but the need for centralized policy management to reduce human error is more important."
Which recommendations should the SE make?
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.
