VMware vSphere & vSAN, The 1st & Only HCI Solution That is Part of a DISA STIG


On 13 APR 2017, VMware announced that VMware vSAN has been added to the VMware vSphere STIG Framework. The updated DISA STIG defines secure installation requirements for deploying vSAN on U.S. Department of Defense (DoD) networks. VMware worked closely with DISA to include vSAN in this update to the existing VMware vSphere STIG Framework. With this update, VMware HCI, comprised of vSphere and vSAN, is the first and only HCI solution that has DISA published and approved STIG documentation.

What is DISA?

DISA is an acronym for Defense Information Systems Agency.


Our Mission

DISA, a Combat Support Agency, provides, operates, and assures command and control, information sharing capabilities, and a globally accessible enterprise information infrastructure in direct support to joint warfighters, national level leaders, and other mission and coalition partners across the full spectrum of operations.

What is a STIG?

STIG is an acronym for Security Technical Implementation Guides (STIGs)


The Security Technical Implementation Guides (STIGs) and the NSA Guides are the configuration standards for DOD IA and IA-enabled devices/systems. Since 1998, DISA has played a critical role enhancing the security posture of DoD’s security systems by providing the Security Technical Implementation Guides (STIGs). The STIGs contain technical guidance to “lock down” information systems/software that might otherwise be vulnerable to a malicious computer attack.

The purpose of a DISA STIG, is to reduce information infrastructure vulnerabilities. These guides are primarily created as guidance for deployment and operations of U.S. Government infrastructure, though it is not uncommon for other organizations use them as well.

This is because information security is not exclusive to the U.S. Government. Security is important to organizations across all verticals, such financial, health care, and retail to name a few. Any organization that is interested in operating with a more security aware posture, can use these publicly available STIGs to better secure their environment. DISA STIGs can be found on the Information Assurance Support Environment website.

The acronym STIG is not a copyrighted term, but is uniquely associated with DISA.

DISA is mandated to develop STIGs against a very specific set of standards in collaboration with the NSA and other organizations. This is a formal process that is very time consuming, requiring close collaboration among all involved. When the Risk Management Executive signs and approves the STIG, it validates that the product in the STIG meets the risk acceptance level for use in the DoD. If important requirements are not met, DISA can and will refuse to sign/approve a proposed STIG.

It is not uncommon to hear the term “STIG Compliant,” but this does not indicate being included in a certified, approved, and published DISA STIG. Achieving the inclusion in a DISA STIG is no small feat. Only through the coordination with and approval by DISA can security guidelines be part of a DISA STIG.

At VMware, we are excited to have VMware HCI included in the VMware vSphere STIG Framework to be able to provide this level of security to customers who need complete certainty about their security profile.
