Decision Constraints


[1]	If free trialware is utilized, the software must be purchased or removed at the end of the trial period. This technology requires using a Universal Service Bus (USB) technology to transfer data into the records. As such, proper precautions need to be taken to protect data. This technology should not be used with Open Java Development Kit (OpenJDK) as it is unapproved for use at this time. There are other approved java environments available. See Category tab for details. Users must ensure that Google Chrome, Firefox, and Microsoft Edge are implemented with VA-approved baselines. (Refer to the ‘Category’ tab under ‘Runtime Dependencies’) Per the Security Assessment Review, users must abide by the following constraints: ESChat PC Client for Windows will require a 3rd party FIPS 140-2 or its successor certified solution for any data containing PHI/PII or VA sensitive information. System Owners/Administrators need to be aware that Windows Defender blocks the installation of the product. Once the file is downloaded, the unblock option must be checked in the file properties to allow installation. To mitigate, an administrator shall monitor the .exe files used by the application with a file integrity checker to ensure no unauthorized changes occur. To mitigate, the vendor must maintain all third-party components during the entire product lifecycle, including responding to vulnerabilities discovered in third-party components used in the product. To mitigate, the ISSO shall educate and prohibit users from using the integrated cloud service capability until the VA Cloud Security Requirements have been met and the affected A&A package has been appropriately updated. To mitigate, an administrator shall verify that the version of the software that they are requesting is the same version number that shows up on the installed systems Programs and Features. To mitigate, an administrator shall contact the vendor to request a hash to use to verify the validity of the downloaded installer file as well as the installed executable and ensure that these files are validated before use.

[2]	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.

[3]	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 approved and the user should take the proper steps to decline those installations.

[4]	Technology must remain patched and operated in accordance with Federal and Department security policies and guidelines in order to mitigate known and future security vulnerabilities.

[5]	Due to potential information security risks for cloud-based technologies, users should coordinate closely with their facility ISSO for guidance and assistance on cloud products. If further guidance is needed contact the Enterprise Cloud Solution Office (ECSO), which is the body responsible for new software development in and migration of existing systems to the VA Enterprise Cloud (VAEC) and ensuring organizational information, Personally Identifiable Information (PII), Protected Health Information (PHI), and VA sensitive data are not compromised within the VAEC.
