5V0-41.21 Exam Dumps : VMware NSX-T Data Center 3.1 Security

The NSX Edge nodes require access to the Internet to download category and reputation definitions, and a layer 7 gateway firewall rule must be configured on the tier-1 gateway uplink to capture DNS traffic. This will allow the URL Analysis service to analyze incoming DNS traffic and block malicious requests. For more information, please see this VMware Documentation article[1], which explains how to configure URL Analysis on NSX.

Zero-Trust with segmentation is a security strategy that uses micro-segmentation to protect a network from malicious actors. By breaking down the network into smaller segments, the NSX Distributed Firewall can create a zero-trust architecture which limits access to only users and devices that have been authorized. This reduces the risk of a malicious actor gaining access to sensitive data and systems.

Lateral Movement of Attacks prevention is another use-case for the NSX Distributed Firewall. Lateral movement of attacks are when an attacker is already inside the network and attempts to move laterally between systems. The NSX Distributed Firewall can help protect the network from these attacks by controlling the flow of traffic between systems and preventing unauthorized access.
