When considering how to implement security within out virtual environments the ideal solution is to block all traffic except for service that we as the administrator specify. Sometimes this is difficult to implement into an existing environment as we need to have a full understanding of how the applications communicate and what services are required. One easy way to get started is to group together common workloads into NSX Security Groups and apply rules just to these workloads.
In this video I will walk through creating 3 type of security groups that can be used alongside the distributed firewall (DFW) to protect virtual machines.
Using Security Groups is a great way to get started with DFW configuration and this is one method of grouping virtual machines within NSX. If you would like to know more about VMware NSX then please get in touch.
