In order to block the gambling websites, the security administrator needs to update the URL Analysis Attributes in NSX-T. URL Analysis Attributes are used to control access to web content, and can be configured to deny access to certain web destinations based on domain names or categories.
For more information on URL Analysis Attributes and how to configure them, please refer to the NSX-T Data Center documentation [1]: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/nsx-t-3.0-url-profile/GUID-F8BA3F3F-4A27-4B4F-8D2A-A013F68E1619.html

The NSX administrator has enabled logging for the distributed firewall rule, and the logs are stored in the /var/log/dfwpktlogs.log file on the ESXi host. This log file stores the packet logs for the distributed firewall rules, and the logs can be used for auditing and troubleshooting the distributed firewall.

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: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/nsx-t-3.0-endpoint-protection/GUID-25C22F02-4B30-47D4-8F0C-3BC9F9C3AFD3.html

The four use cases for NSX Tags are Manageability, Third-party sharing/context sharing, Security, and Troubleshooting (Traceability). NSX Tags provide an easy way to organize, document, and manage virtual networks and can be used to track changes and enforce security policies. They can also be used to share context between third-party providers, such as cloud service providers, to ensure that security policies are adhered to. Additionally, NSX Tags can be used for logging and troubleshooting by providing traceability and making it easier to debug network issues.
