Açıklama

sudo caches used credentials for a default of 5 minutes. This is for ease of use when there are multiple administrative tasks to perform. The timeout can be modified to suit local security policies. Audit: Passes when every timestamp_timeout in /etc/sudoers and /etc/sudoers.d is between 0 and 15 minutes; with none set the sudo default of 5 minutes applies.

Düzeltme yöntemi: Kılavuz veya altyapı yaması

If the currently configured timeout is larger than 15 minutes, edit the file listed in the audit section with visudo -f <PATH TO FILE> and modify the entry timestamp_timeout= to 15 minutes or less as per your site policy. The value is in minutes. This particular entry may appear on its own, or on the same line as env_reset. See the following two examples: Defaults env_reset, timestamp_timeout=15 Defaults timestamp_timeout=15 Defaults env_reset
