Review the application documentation and interview the application administrator. Identify all software components. Review the version information and identify the vendor if COTS software. Access the vendor website to verify the version is still supported. Ask the application representative for proof that the application and all of its components are supported. Examples of proof may include: design documentation that includes support information, support specific contract documentation, successful creation of vendor support tickets, website toll free support phone numbers etcetera. If any of the software components are not supported by a COTS vendor or a GOTS organization, this is a finding.
