In the following sections, we will explore how vSphere Trust Authority works, the areas of security it improves, the deployment use cases of vSphere Trust Authority, and supporting examples to help both technical security and executive decision makers understand how it can strengthen their virtual infrastructure. By the end of this article, readers should have a comprehensive understanding of the benefits of vSphere Trust Authority and how it can help organizations establish a more secure and compliant virtual infrastructure.


What is VMware vSphere Trust Authority?


VMware vSphere Trust Authority is a security solution designed to help organizations establish trust in their virtual infrastructure. By using digital certificates and cryptographic techniques, Trust Authority verifies the trustworthiness of each component of the virtual infrastructure, including the hypervisor, virtual machines (VMs), and hosts. Once verified, components are assigned a trust level based on their level of risk, which is used to determine whether the component is allowed to run. Trust Authority enables organizations to establish a secure and trusted computing environment that is resistant to attacks and other security threats.


How does vSphere Trust Authority work?


vSphere Trust Authority works by establishing trust in each component of the virtual infrastructure. It uses digital certificates to verify the identity and integrity of each component and ensure that it is trustworthy. Once a component is verified, it is assigned a trust level based on its level of risk. This trust level is used to determine whether the component is allowed to run on the virtual infrastructure.


Areas of security that are improved by vSphere Trust Authority


In essence, Trust Authority is designed to provide organizations with a way to establish a trusted computing environment. It accomplishes this by using a combination of cryptographic techniques and digital certificates to verify the identity and integrity of each component. This trust level is used to determine whether the component is allowed to run on the virtual infrastructure. Trust Authority enables organizations to establish a secure and trusted computing environment that is resistant to attacks and other security threats.

vSphere Trust Authority improves security in several areas of the virtual infrastructure, including:


  • Platform security: vSphere Trust Authority verifies the trustworthiness of the hypervisor and ensures that it is free of vulnerabilities and malware. An example is using technologies such as VM Encryption, which not only introduces data encryption for both the virtual machine (VM) but the underlying datastores, but which is also the prerequisite and enhancement for other security features such as Virtual Trusted Platform Modules (vTPMs) on VMs.

  • VM security: vSphere Trust Authority verifies the identity and integrity of each VM. VMware offers several solutions to help organizations establish a secure VM environment. Trust Authority can enforce policies that protect against unauthorized access to VMs by providing granular control over who can access VMs and what actions they can perform. For example, an organization can set up a policy that requires multi-factor authentication for anyone attempting to access a VM.

  • Host security: vSphere Trust Authority verifies the trustworthiness of each host. For example, vSphere Secure Boot with Trusted Platform Modules (TPMs) helps ensure that the hypervisor boots securely and with the correct firmware. Secure Boot uses digital signatures to verify the integrity of the hypervisor and firmware, preventing unauthorized components from running. TPMs allow for a secure location for “secrets” to be stored including vendor digitally signed certificates.

  • Compliance: Compliance is a critical consideration for organizations in today's digital landscape. vSphere Trust Authority supports compliance with the Payment Card Industry Data Security Standard (PCI DSS) by enabling organizations to establish a trusted computing environment. This helps protect critical systems and data from cyber threats and maintain regulatory compliance. Additionally, vSphere Encryption provides encryption at rest, helping organizations meet compliance requirements for data protection. By encrypting data, organizations can maintain compliance with various data privacy and protection regulations, such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA).

Deployment use cases of vSphere Trust Authority


vSphere Trust Authority can be used in a variety of deployment scenarios, including:

  • Private clouds: In a private cloud, vSphere Trust Authority establishes trust in the virtual infrastructure by ensuring that only trusted components are allowed to run. This helps protect sensitive data and critical systems from unauthorized access. The unique protection provided by vSphere Trust Authority in a private cloud is the ability to assign trust levels to each component of the cloud, enabling a scalable and adaptable solution.

  • Hybrid clouds: In a hybrid cloud deployment, vSphere Trust Authority establishes trust between different clouds. By ensuring that only trusted components are allowed to run on the hybrid cloud, it helps prevent attacks that exploit vulnerabilities in the cloud infrastructure. The unique protection provided by vSphere Trust Authority in a hybrid cloud is the ability to establish trust across different clouds and prevent security threats arising from a lack of trust.

  • Multi-tenant environments: In a multi-tenant environment, vSphere Trust Authority establishes trust between different tenants. By ensuring that each tenant's data is protected from unauthorized access, organizations can maintain the privacy and security of their clients' data. The unique protection provided by vSphere Trust Authority in a multi-tenant environment is the ability to establish trust between different tenants and prevent data breaches and attacks that exploit vulnerabilities in the environment.

  • Virtual desktop infrastructure (VDI): In a virtual desktop infrastructure deployment, vSphere Trust Authority establishes trust in the hypervisor and the VMs. By assigning trust levels to each component of the VDI environment, organizations can ensure that only trusted components are allowed to run. This helps protect sensitive data and critical systems from cyber threats. The unique protection provided by vSphere Trust Authority in a VDI environment is the ability to establish trust in the hypervisor and VMs, enabling a scalable and adaptable solution to meet the organization's specific security needs.

Challenges to deploying Trust Authority


While VMware vSphere Trust Authority can provide organizations with significant benefits in terms of security and compliance, there are some potential drawbacks and challenges to consider when planning, designing, and deploying it.


One of the main challenges is the complexity of deploying and managing Trust Authority, especially in large or complex environments. Organizations need to have a clear understanding of their virtual infrastructure and security requirements, as well as a solid plan for implementing and maintaining Trust Authority. This can require significant resources, including specialized expertise, tools, and processes.


Another challenge is compatibility with existing hardware and software components. Trust Authority relies on hardware-assisted security features, such as TPM chips, to establish and maintain trust. If an organization's existing hardware does not support these features, they may need to upgrade or replace it, which can be costly and time-consuming.


Trust Authority requires a significant amount of configuration and management, which can be challenging for organizations with limited IT resources or expertise. The process of establishing and maintaining trust can be complex and time-consuming and requires ongoing monitoring and maintenance to ensure that the virtual infrastructure remains secure and compliant.


The use of Trust Authority can also introduce some performance overhead, especially in environments with high workloads or strict latency requirements. This can be mitigated through careful design and configuration but may still be a consideration for some organizations.


The biggest drawbacks and challenges to planning, designing, and deploying vSphere Trust Authority include its complexity, compatibility with existing hardware and software, configuration and management requirements, and potential performance overhead. Organizations need to carefully weigh these factors against the benefits of Trust Authority before deciding whether to implement it in their environment.
