Where this suit touches others

Data and Inference and Lifecycle: data covers what is kept and where; lifecycle covers what happens to it when the household, the device or the provider changes.

STRIDE, LINDDUN, CAPEC and CWE

Of the 6 entries here, STRIDE fits 1 cleanly and 4 only loosely, and none of its categories applies to 1. LINDDUN fits 1 cleanly and 3 only loosely, and has no category for 2. CAPEC 3.9 has nothing for any of them. CWE 5.0 names the weakness directly for 1, has only a broader weakness for 1 and has nothing for 4. All four frameworks miss 4 of them: no clean STRIDE or LINDDUN prompt, and no direct CAPEC or CWE match. The table below gives the mapping entry by entry, with the names of the CAPEC patterns and CWE weaknesses; what the mapping shows across the whole taxonomy is in Mapping the Care Assistant Threat Taxonomy to STRIDE, LINDDUN, CAPEC and CWE. The Excel, SKOS and STIX downloads carry the same mapping as text.
