What it makes you produce

One item for your checklist.

  1. Something you fill in and send back

    Hours, once you know which one is missing.

    • A report — contract number, supplier, brand, model number and item description — with mitigation detail and the prevention steps taken and planned within 10 business days after it

      Owed when you identify a Kaspersky Lab covered article in what you supply or use — the first report is due within three business days of that

      FAR 52.204-23(c)

When it is used

All contracts, no threshold, including commercial/COTS.

Read closely

Paragraph (b) is the prohibition on providing such an article or using one in developing a deliverable, and paragraph (d) carries the substance into all subcontracts, commercial ones included. The check itself is a software inventory. Reports on a defense order go to dibnet.dod.mil. The model text for the FAR overhaul prints this number as reserved and consolidates the prohibition into FAR 52.240-91.
