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.

NSX-T Endpoint Protection provides agentless antivirus protection for virtual machines running on VMware ESXi hosts. It uses the VMware vShield Endpoint API to scan the virtual machines without requiring the installation of antivirus agents. The service is integrated with third-party antivirus solutions, such as McAfee and Symantec, to provide real-time protection against malware and other threats.

For more information on NSX-T Endpoint Protection, please refer to the NSX-T Data Center documentation: 

The two prerequisites before configuring the VMware Identity Manager (vIDM) service for NSX-T Data Center are Configure vIDM Integration and Certificate Thumbprint from vIDM. In order to use vIDM for authentication, it must be integrated with NSX-T Data Center, which will involve configuring the vIDM integration service. Additionally, a certificate thumbprint from vIDM must be provided to NSX-T Data Center to enable secure communication between the two services. Time synchronization and assigning roles to users are not necessary prerequisites for configuring the vIDM service. References: [1]   [2]

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.

[1] 

To use URL Analysis, you will need to have a Tier-1 gateway and a Layer 7 DNS firewall rule on the NSX Edge cluster. Additionally, you will need to configure an OFW rule allowing traffic OUT to the Internet. Lastly, a medium-sized edge node (or higher), or a physical form factor edge is also required as the URL Analysis service will run on the edge node. For more information, please see this VMware Documentation article[1], which explains how to configure URL Analysis on NSX.

 Component Manager is used to deploy the Partner Service VM on every host of a cluster configured for guest introspection.

For further reading, see the VMware NSX-T Data Center Administration Guide (  for more information on configuring guest introspection.

NSX provides a feature called Guest Introspection that allows administrators to provide security services to virtual machines, including antivirus protection. One of the components of Guest Introspection is the Guest Introspection Thin Agent, which must be deployed to provide Linux-based VMs with antivirus protection. The Thin Agent is a lightweight agent that runs inside the guest operating system of virtual machines and communicates with the NSX Manager to provide security services.

Once the Guest Introspection Thin Agent is deployed, the administrator can configure the antivirus service to scan virtual machines for malware and take action on any threats that are detected.
