Securing VMs

So you enabled the vSphere Compliance module in vRealize Operations Manager and now your VMs are all reporting the following alert.

“Virtual Machine is violating Risk Profile 1 in VMware vSphere Security Configuration Guide”

Viewing the details shows symptoms similar to the following:

0017

I’m not going to cover the details on what each setting does but for the most part these are safe to run, however if your are concerned about what it might do you should test it for yourself.

Note: This will not remove the floppy drive since the VM needs to be powered down and I didn’t need to disable that for many of the VMs when I built this.

    1. Thanks for your reply, my point with this was to how to automate some of the task related to “checking off” that security box for an auditor but I realize that the title could be misleading.

      Thank you for all your work in making ESXi secure by default and reducing the managment effort that we have to put in to make it secure!
