Le verrouillage d’un ordinateur apr\u00e8s une p\u00e9riode d’inactivit\u00e9 est une mesure de s\u00e9curit\u00e9 indispensable et recommand\u00e9e par tous les professionnels de l’informatique. En particulier dans les environnements partag\u00e9s ou publics, cela permet de s’assurer qu’un poste de travail non surveill\u00e9 ne devient pas une opportunit\u00e9 pour des personnes malveillantes. PowerShell est un pilier de nombreuses op\u00e9rations informatiques dans les environnements Windows et offre un moyen polyvalent de d\u00e9finir un d\u00e9lai d’inactivit\u00e9.\u00a0<\/strong><\/p>\n

Contexte<\/h2>\n

Le d\u00e9lai d’inactivit\u00e9 n’est pas seulement une question de s\u00e9curit\u00e9, mais aussi de gestion des ressources. Les professionnels de l’informatique et les fournisseurs de services g\u00e9r\u00e9s (MSP)<\/a> utilisent souvent cette fonction pour \u00e9conomiser de l’\u00e9nergie, r\u00e9duire l’usure du mat\u00e9riel et cr\u00e9er une premi\u00e8re couche de s\u00e9curit\u00e9. Le script fourni permet d’automatiser ce processus, ce qui permet de le configurer et de ne plus s’en soucier.<\/p>\n
