This is something that has been long sought after by many. The hardening guide is 38 pages long packed with hardening information for the vRA Appliance, IaaS Server, Identity Appliance, and Application services appliance. This document takes you through the hardening of the SLES 11, PostgresSQL, Windows Host including SQL Server, IIS, and Microsoft .Net. The hardening guide also covers the network security and securing communications between the vRA components.
The network security section of the guide includes a complete list of all the vRA components and the ports/protocols that are used by the component. Even if you are not ready to start creating a fully hardened deployment it’s worth taking a look at the guide and becoming familiar with the the communications between the different components.
