La s\u00e9curit\u00e9 des donn\u00e9es priv\u00e9es et professionnelles devient de plus en plus importante, car la criminalit\u00e9 se d\u00e9place de plus en plus vers l'Internet. La s\u00e9curit\u00e9 des donn\u00e9es ne concerne pas seulement la protection des donn\u00e9es sensibles, mais aussi, de mani\u00e8re g\u00e9n\u00e9rale, la s\u00e9curit\u00e9 de toutes les donn\u00e9es de l'entreprise. Les entreprises ont ici diff\u00e9rentes possibilit\u00e9s d'optimiser la protection et la s\u00e9curit\u00e9.<\/p>\n

Droits d'acc\u00e8s<\/h2>\n

Le contr\u00f4le des droits d'acc\u00e8s est un \u00e9l\u00e9ment important de la s\u00e9curit\u00e9 des donn\u00e9es. De nombreux syst\u00e8mes offrent d\u00e9j\u00e0 la possibilit\u00e9 d'imposer des restrictions simples, par exemple en autorisant simplement certaines actions dans les dossiers. Les entreprises ne peuvent toutefois pas \u00e9viter d'utiliser des outils appropri\u00e9s pour prot\u00e9ger les donn\u00e9es.<\/p>\n

Il est ainsi possible de distribuer des droits d'acc\u00e8s et d'utilisation non seulement pour des dossiers, mais aussi pour des fichiers individuels ou des zones de collections de donn\u00e9es. Il est particuli\u00e8rement important que ces droits soient \u00e9galement contr\u00f4l\u00e9s r\u00e9guli\u00e8rement. Il arrive r\u00e9guli\u00e8rement que des collaborateurs licenci\u00e9s n'aient pas d\u00e9sactiv\u00e9 leurs comptes et que ceux-ci aient ensuite caus\u00e9 des dommages consid\u00e9rables dans l'entreprise.<\/p>\n

Versionnement<\/h2>\n

La s\u00e9curit\u00e9 des donn\u00e9es n'est plus garantie non plus lorsque l'on travaille avec une base de donn\u00e9es obsol\u00e8te. Deux facteurs en sont g\u00e9n\u00e9ralement responsables : un manque d'espace de stockage partag\u00e9 et l'absence de versionnage indiquant quand un document a \u00e9t\u00e9 modifi\u00e9.<\/p>\n

Gr\u00e2ce au stockage dans le nuage, le premier probl\u00e8me au moins peut \u00eatre facilement r\u00e9solu. En ce qui concerne le versionnement, il existe des logiciels appropri\u00e9s qui documentent qui a fait quelles modifications et quand. L'avantage est qu'ils montrent non seulement qui a travaill\u00e9 dessus, mais aussi quelles modifications ont \u00e9t\u00e9 apport\u00e9es. C'est indispensable pour les documents qui sont trait\u00e9s en commun par une \u00e9quipe, mais il est aussi souvent utile de pouvoir suivre l'\u00e9volution d'un document pour les fichiers qui ne sont utilis\u00e9s que par une seule personne.<\/p>\n

Cr\u00e9er des sauvegardes<\/h2>\n

Autrefois, on faisait des copies de tous les documents, aujourd'hui ce sont les sauvegardes des supports de donn\u00e9es qui doivent \u00eatre faites \u00e0 intervalles r\u00e9guliers. Cela ne concerne pas seulement les supports de donn\u00e9es dans l'entreprise, mais aussi, par exemple, les serveurs qui sont utilis\u00e9s. Les back-ups sont n\u00e9cessaires pour R\u00e9cup\u00e9ration des donn\u00e9es du serveur<\/a> est indispensable, car une perte peut survenir suite \u00e0 des attaques de pirates ou \u00e0 d'autres probl\u00e8mes. Si une sauvegarde est disponible, la perte de donn\u00e9es est minimale et les temps d'arr\u00eat peuvent \u00eatre r\u00e9duits.<\/p>\n

De nombreuses entreprises se demandent \u00e0 quelle fr\u00e9quence il est judicieux de sauvegarder les donn\u00e9es du serveur. La r\u00e9ponse \u00e0 cette question est toujours individuelle. Plus la fr\u00e9quence d'utilisation est \u00e9lev\u00e9e, plus les sauvegardes doivent \u00eatre fr\u00e9quentes. Pour les petites et moyennes entreprises, une sauvegarde quotidienne est g\u00e9n\u00e9ralement suffisante. Les entreprises qui re\u00e7oivent des centaines de commandes de clients par jour devraient envisager de faire un back-up toutes les quelques heures.<\/p>\n

Les sauvegardes doivent \u00eatre conserv\u00e9es pendant un certain temps. De nombreuses entreprises conservent m\u00eame les sauvegardes jusqu'\u00e0 un an. La raison en est que si des donn\u00e9es ont \u00e9t\u00e9 endommag\u00e9es par des virus, il faut souvent un certain temps pour s'en apercevoir. Les donn\u00e9es endommag\u00e9es sont alors souvent copi\u00e9es lors des sauvegardes. S'il n'y a plus de sauvegarde qui pr\u00e9sente un \u00e9tat des donn\u00e9es avant un dommage, de telles informations ne peuvent g\u00e9n\u00e9ralement plus \u00eatre restaur\u00e9es.<\/p>\n

S\u00e9curit\u00e9 physique<\/h2>\n

La s\u00e9curit\u00e9 physique des supports de donn\u00e9es doit \u00e9galement \u00eatre prise en compte dans la s\u00e9curit\u00e9 des donn\u00e9es. Comme pour l'acc\u00e8s aux fichiers, l'acc\u00e8s \u00e0 la salle des serveurs, par exemple, doit \u00eatre prot\u00e9g\u00e9 par des autorisations. Par ailleurs, l'entretien et le stockage des supports de donn\u00e9es sont \u00e9galement des facteurs importants. Une sauvegarde est inutile si elle se trouve sur un support de donn\u00e9es qui a \u00e9t\u00e9 expos\u00e9 \u00e0 une chaleur excessive, par exemple \u00e0 la suite d'un mauvais stockage, ce qui l'a rendu inutilisable.<\/p>\n

Les entreprises qui travaillent en grande partie sans papier sont dans ce cas \u00e9galement soumises \u00e0 des dispositions l\u00e9gales qui r\u00e8glent la mani\u00e8re dont les supports de donn\u00e9es doivent \u00eatre conserv\u00e9s pour satisfaire \u00e0 l'obligation de conservation.<\/p>","protected":false},"excerpt":{"rendered":"
