The VA Decision Matrix displays the current and future VAIT position regarding different releases of a TRM entry. These decisions are based upon the best information available as of the most current date. The consumer of this information has the responsibility to consult the organizations responsible for the desktop, testing, and/or production environments to ensure that the target version of the technology will be supported.

Legend:

White	Authorized: The technology/standard has been authorized for use.
Yellow	Authorized w/ Constraints: The technology/standard can be used within the specified constraints located below the decision matrix in the footnote[1] and on the General tab.
Gray	Authorized w/ Constraints (POA&M): This technology or standard can be used only if a POA&M review is conducted and signed by the Authorizing Official Designated Representative (AODR) as designated by the Authorizing Official (AO) or designee and based upon a recommendation from the POA&M Compliance Enforcement, has been granted to the project team or organization that wishes to use the technology.
Orange	Authorized w/ Constraints (DIVEST): VA has decided to divest itself on the use of the technology/standard. As a result, all projects currently utilizing the technology/standard must plan to eliminate their use of the technology/standard. Additional information on when the entry is projected to become unauthorized may be found on the Decision tab for the specific entry.
Black	Unauthorized: The technology/standard is not (currently) permitted to be used under any circumstances.
Blue	Authorized w/ Constraints (PLANNING/EVALUATION): The period of time this technology is currently being evaluated, reviewed, and tested in controlled environments. Use of this technology is strictly controlled and not available for use within the general population. If a customer would like to use this technology, please work with your local or Regional OI&T office and contact the appropriate evaluation office displayed in the notes below the decision matrix. The Local or Regional OI&T office should submit an inquiry to the TRM if they require further assistance or if the evaluating office is not listed in the notes below.

Release/Version Information:

VA decisions for specific versions may include a ‘.x’ wildcard, which denotes a decision that pertains to a range of multiple versions.

For example, a technology authorized with a decision for 7.x would cover any version of 7.(Anything) - 7.(Anything). However, a 7.4.x decision would cover any version of 7.4.(Anything), but would not cover any version of 7.5.x or 7.6.x on the TRM.

VA decisions for specific versions may include ‘+’ symbols; which denotes that the decision for the version specified also includes versions greater than what is specified but is not to exceed or affect previous decimal places.

For example, a technology authorized with a decision for 12.6.4+ would cover any version that is greater than 12.6.4, but would not exceed the .6 decimal ie: 12.6.401 is ok, 12.6.5 is ok, 12.6.9 is ok, however 12.7.0 or 13.0 is not.

Any major.minor version that is not listed in the VA Decision Matrix is considered Authorized w/ Constraints (POA&M).

Decision Constraints


[12]	Users should check with their supervisor, Information System Security Officer (ISSO) or local OIT representative for permission to download and use this software. Downloaded software must always be scanned for viruses prior to installation to prevent adware or malware. Freeware may only be downloaded directly from the primary site that the creator of the software has advertised for public download and user or development community engagement. Users should note, any attempt by the installation process to install any additional, unrelated software is not authorized and the user should take the proper steps to decline those installations.

[13]	Due to National Institute of Standards and Technology (NIST) identified security vulnerabilities, extra vigilance should be applied to ensure the versions remain properly patched to mitigate known and future vulnerabilities. The local ISSO (Information System Security Officer) can provide assistance in reviewing the NIST vulnerabilities.

[14]	In cases where the technology is used for external connections, a full Enterprise Security Change Control Board (ESCCB) review is required in accordance VA Directive 6004 , VA Directive 6517, and VA Directive 6513. The local ISSO (Information System Security Officer) can advise on the ESCCB review process.

[15]	Veterans Affairs (VA) users must ensure VA sensitive data is properly protected in compliance with all VA regulations. All instances of deployment using this technology should be reviewed by the local ISSO (Information System Security Officer) to ensure compliance with both VA Handbook 6500 and VA Directive 6500.

[16]	If free trialware is utilized, the software must be purchased or removed at the end of the trial period. Users must not utilize ActiveTcl, as it is at the time of writing, unapproved in the TRM. Users must not utilize Diagnostics and Recovery Toolset (DaRT), as it is at the time of writing, unapproved in the TRM.

[17]	The Federal Information Processing standards (FIPS) 140-2 certification status of this technology was not able to be verified. This technology will require a 3rd party FIPS 140-2 or 140-3 certified solution for any data containing PHI/PII or VA sensitive information, where applicable. More information regarding the Cryptographic Module Validation Program (CMVP) can be found on the NIST website.

As open-source software, this product may be left without clearly defined support options which may result in suboptimal enterprise level support.
Due to the rapid release schedule of this technology, the VA may be unable to update to the most recent patch and may require a deployment model requiring the use of specific versions.
There are other authorized solutions that provide similar functionality available on the TRM. The use of several similar solutions may increase organization requirements for support and maintenance.
There are known Common Vulnerabilities and Exposures (CVEs) associated with this technology. Please see https://nvd.NIST.gov/vuln/search for more details.
The potential exists to store Personally Identifiable Information (PII), Protected Health Information (PHI) and/or VA Sensitive data and proper security standards must be followed in these cases

Architectural Benefits

This technology is compatible with virtual machines, therefore consistent with the enterprise Server Virtualize First Policy (VAIQ 7266972 08-27-2012).
