Not only will this make it more difficult for attackers but the result of removing administrative privileges from the root user will also disable SSH access for this user automatically and also prevent login access to the ESXi Host Client or ESXi API, so you actually get three benefits by simply applying this configuration in your environment. As a result, this can lock you out of your ESXi hosts or worse, enable an attacker to encrypt your workloads, especially as the rise ransomeware attacks has been increasing.Īnother ESXi security configuration that is definitely worth applying and mentioned in the ESXi security documentation is to create a new ESXi local administrative user and then remove the administrative privileges for the default root account user, which most attackers will assume this account exists on your ESXi host.
ESXI SHELL PASSWORD
By restricting ESXi Shell access for the vpxuser, you prevent attackers, which can also be insiders who have access to vCenter Server the ability to just change the ESXi root password without knowing the original password. It turns out that users with ESXi Shell access can also modify other local users password on ESXi host including the root user. While this might sound like a pretty basic feature, applying this towards the vCenter Server service account vpxuser can help add another layer of protection for your ESXi hosts against attackers. Speaking of new ESXi security enhancements, one of the new features that was introduced in ESXi 8.0 is the ability to disable ESXi Shell access for non-root users. After answering some of the security related questions, especially on the Automation examples, I figure it would be useful to share this information more broadly so that folks are aware of some of the new and existing security enhancements along with some of their implications if you are not implementing them. In certain areas of the ESXi security documentation, I noticed that it mentions CLI and API, but it does not always provide an example that customers can then reference and use in their Automation, which is really the only guaranteed method to ensure configurations are consistent across your vSphere environment. It is definitely worth re-reviewing this section from time to time to take advantage of all the ESXi security enhancements to help protect and secure your vSphere environment. Tee /vmfs/volumes/storage/test/test.While responding to a few ESXi security configuration questions, I was referencing our ESXi Security documentation, which includes a lot of useful information and latest best practices. Vmkfstools -X 20G /vmfs/volumes/storage/test/test.vmdk Vmkfstools -clonevirtualdisk /vmfs/volumes/storage/iso/system.vmdk -diskformat thin /vmfs/volumes/storage/test/test.vmdk There are set of generated parameters like uuid.bios, uuid.location, vm.createDate and most of others are just defaults I did tried to remove all non required options till I was able to register an vm and it seems that almost everything can be removed, I have stopped after some period where it loose any sence You can create folder in ESXi, put this file there and register VM
