NISP Tips on eMASS DCSA “TRExport” Spreadsheet Information

The “Test Results” field is one of the most heavily scrutinized areas within the TRExport” spreadsheet, and understandably so, as DCSA personnel want to know exactly what test procedures were performed for validating the control. With that said, you need to provide relevant, factual, detailed information. But remember, DCSA personnel do not want to read a novel - as they often object to overly long, multi-paragraph, wordy answers just as much as they do to short and/or templated answers.  Also, per a recent presentation by DCSA personnel:

  • “Test Results are not Implementation Narrative details or ConMon.”
  • “Test Results are a summary of the actions that have already taken place to validate that controls have been effectively implemented.”
  • For example, for MP-2.1, Media Protection, you’ll need to describe how the control was actually tested. An excellent example answer would be the following:

The ABC Company ISSM validated that a Media Protection Policy and Procedures document is in place, reviewed and updated as needed on an annual basis. The document contains all necessary information pertaining to defining personnel roles and responsibilities. ISSM also conducted physical inspection of the information system to confirm that the only types of media allowed are external USB Drives and external optical drives, both of which are secured at all times. Also, ISSM confirmed through physical inspection that there are hardware plugs on vacant ports, only authorized personnel can handle media, and if necessary, media will be destroyed per DoD guidelines.
