Principe du besoin de savoir<\/h1>\n

Que signifie le principe du \"besoin de savoir\" ?<\/strong><\/p>\n

Le principe du besoin d'en conna\u00eetre (Need-to-know), \u00e9galement appel\u00e9 principe de n\u00e9cessit\u00e9, d\u00e9crit le fait que chaque employ\u00e9 d'un service responsable ne re\u00e7oit que les informations qui lui sont utiles et dont il a besoin pour accomplir sa t\u00e2che. Il s'agit donc d'une TOM importante pour atteindre un niveau de s\u00e9curit\u00e9 ad\u00e9quat (article 32, paragraphe 1, du RGPD), car elle permet d'\u00e9viter la diffusion inutile d'informations et de limiter la prise de connaissance de celles-ci au minimum n\u00e9cessaire. Par exemple, moins de personnes ont acc\u00e8s \u00e0 certaines donn\u00e9es \u00e0 caract\u00e8re personnel (parce qu'elles n'en ont pas non plus besoin), moins le risque de violation des donn\u00e9es est \u00e9lev\u00e9. La mise en pratique du principe du besoin d'en conna\u00eetre se fait par exemple \u00e0 l'aide d'un concept de droits d'utilisateur.<\/p>\n

Exemple pratique<\/h2>\n

Lors du traitement des donn\u00e9es, l'entreprise tient compte du principe du besoin de savoir, en ne collectant que les donn\u00e9es n\u00e9cessaires et en informant de mani\u00e8re transparente sur leur utilisation.<\/p>","protected":false},"excerpt":{"rendered":"
