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.

When configuring members of a Security Group, the permitted membership criteria are Virtual Machine, Physical Machine, Cloud Native Service Instance, and IP Set.

For more information on configuring members of a Security Group, please refer to the NSX-T Data Center documentation: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/nsx-t-3.0-security/GUID-C0F9A9A7-9A1E-41D9-A237-FED7A6F20A0A.html

The tier-0 gateway is the entry point of the NSX-T Data Center network, and it is where the North-South service insertion takes place. The uplink of the tier-0 gateway is the point of connection between the NSX-T Data Center network and the external network.

The guest VM vNIC is the interface card inside the guest virtual machine, which is used to connect the guest VM to the NSX-T Data Center network. North-South services can be inserted at this point as well.

The component in a transport node that receives the firewall configuration from the central control plane is the NSX-MPA (Management Plane Agent). The NSX-MPA runs on each transport node and is responsible for connecting to the NSX-T central control plane and receiving the configuration for the transport node. It is also responsible for pushing the configuration down to the other components on the transport node, such as the NSX-Proxy, NSX-Appl-Proxy, and NSX-CCP.
