French term
intéressant la Défense Nationale
“Présentent un caractère de secret de la défense nationale au sens de la présente section les procédés, objets, documents, informations, réseaux informatiques, données informatisées ou fichiers intéressant la Défense nationale qui ont fait l’objet de mesures de classification destinées à restreindre leur diffusion et leur accès."
"Pénétration frauduleuse sur un terrain, dans une construction ou dans un engin ou appareil quelconque affecté à l’autorité militaire ou placé sous son contrôle.
Nuisance à la Défense nationale et entrave au fonctionnement normal des organismes intéressant la Défense Nationale.
Trois ans d’emprisonnement.
..."
These seem to be somewhere between "coming under the jurisdiction of National Defence" (which sounds too specifically legal to my ears) and "involved in National Defence" (which doesn't sound specific enough).
Not sure an expression could be found which might apply to both examples above but obviously that'd be preferable.

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.
