Publication context, recorded scope and the Rackstamp guides that use this source.

SOURCE CHECK / 2026-10-29

Source context

Recorded scope and limits

Re-read the PCI SSC glossary entries for CDE, system components, scoping and segmentation. The CDE and broader assessment scope must not be treated as identical, and physical labels do not determine either. The guide defers actual scope decisions to the entity and its responsible reviewer. Checked October 29, 2026.

Use the task guides below to see how this source informs a labeling decision. Check the publication scope and the edition adopted by your project before applying it. A publisher overview is not the full text of a standard, and software documentation does not prescribe a physical label format.

Read the library’s edition and applicability notes.

What this source establishes

Provides publisher wording for scope vocabulary. No requirement is restated, and no requirement is asserted to be satisfied by labeling alone.
