VMware for Beginners — What is vSphere Trust Authority: Part 17(a)

What is vSphere Trust Authority?

VMware’s vSphere has a security tool called “vSphere Trust Authority” that helps keep your virtual environment safe from unwanted access and changes. The system authenticates ESXi and vCenter Server systems using hardware and software security methods to do this.

vSphere Trust Authority (vTA) is a new feature in VMware vSphere 7.0 meant to improve a vSphere system’s security. It gives vSphere infrastructure components a way to build trust with each other and make sure they work in a known and proven state.

A Trusted Platform Module (TPM) chip is used by vSphere Trust Authority to store secure keys and information about the software running on an ESXi host. The TPM chip checks the software on an ESXi server when it starts up. The system then sends this data to the vCenter Server, which checks it against a known good figure. If the reading is correct, the ESXi host is thought to be reliable.
