Display subtechniques in the matrix views.

[manonviallet]

Description

There are several issues today with the matrice view display of attack patterns:

• when asking to display only used techniques, the tactics columns where there are no used techniques does not disappear, where as in list view, they are not displayed at all. It would be clearer for the matrice display that unused techniques AND tactics are not displayed when the filter is activated (but it is useful to have the possibility to display the whole matrice, to see what is missing) ;
• The sub-techniques are not displayed in the matrice, whereas in the list view, it is the techniques which are not displayed. At least for the list view, it would be interesting to have an imbrication of techniques and sub-techniques similar to what is done with countries and regions.
• The color code should be explained, as it is not clear why some boxes are redder than others : more relations : this is biased by the fact that the relations are not several same relations to the same technique, but several unique relations to several different sub-techniques.

Environment

2. OpenCTI version 5.0.1
3. OpenCTI client frontend

(update of the issue : the first point which has been suppressed was actually already implemented, but we had never ordered the tactics, so it was not working, of course. My bad)

Ok so @manonviallet this is not a bug (2 other points are most likely feature requests).
