The Security settings are quite confusing with very different security features grouped together and quite a number of settings dumped into a "Miscellaneous" tab.
The use of a "Miscellaneous" section is usually an indication of a not-so-well-conceived UI.

For example, settings like "Warn when trying to send unsigned messages" certainly belong to the "Composing" tab. Probably this is the case for all settings in the "Miscellaneous" tab.

The threshold setting for "Warn if certificates/Keys expire soon" should probably be hidden in a "configure thresholds" dialog as they add unnecessary complexity to the UI, while being initially all the same (= 14 days) and rarely changed.

Also, the "S/MIME" validation settings should probably go to a respective dialog, too, as they are utterly complex, while there is usually no need to change them even for the few people using KMail with S/MIME.

Certainly it would be a good idea to doublecheck which security options make more sense on a "per-identity" basis and/or whether a default configuration that may be overwritten per-identity (such as with templates) would make sense. I leave this to be tackled in another ticket.
