Security Groups are a way to define objects that you want to group together to protect. They can be statically defined or defined dynamically. Security Groups can be defined using some of the following objects:
Grouping objects together can make the application of firewall rules that much easier and cut down on the amount of rules that need to be generated in NSX
To create a security group, navigate to Networking & Security > Service Composer > Security Groups. Click the “New Security Group” icon.
Identity based firewall allows you to make distributed firewall rules based off Active Directory users and groups. A few things need to be in place for this to work. You must have a cluster that is prepared for NSX. You must setup AD synchronization so that NSX can see the users and groups and you must have Guest Introspection and/or AD Event Log Scraper in place. Guest Introspection must be deployed on the clusters where IDFW VMs are running. When network events are created, a guest agent installed on the VM (VMware Tools full installation) forward the information through guest introspection on to the NSX manager. With Active Directory event log scraper, you must point the NSX manager to a AD domain controller. The NSX manager then pulls the events from the AD security event log and filter through the firewall rules accordingly. IDFW monitors where AD users log in, maps the login to a IP address, and that is used by the DFW to apply rules. Read Full Article
Using NSX Edge, you can create a L2 VPN that can stretch multiple logical networks, whether VLAN or VXLAN, across geographical sites. With L2 VPN, a VM can remain on the same subnet when moved between sites and their IP addresses do not have to change. To configure a L2 VPN, you configure a L2 VPN server (destination Edge) and an L2 VPN client (source Edge). Then you enable L2 VPN services on both. But before we can create the L2 VPN, we must create a trunk port on our NSX edge. Read Full Article
