Ensure users must provide password for escalation

低等級 2自動化linux

說明

sudo can be configured to require users to authenticate before running commands with elevated privileges. The NOPASSWD tag, where present in the sudoers configuration, lets a user run sudo commands without entering a password; without it, sudo prompts for the user's password before escalating privileges.

修補方式

修補方法: 操作指南或基礎設施修補檔

Based on the outcome of the audit procedure, use visudo -f <PATH TO FILE> to edit the relevant sudoers file. Remove any line with occurrences of NOPASSWD tags in the file. Because sudo applies the last matching Defaults (and per-rule) definition, ensure no later-parsed file in /etc/sudoers.d re-introduces a NOPASSWD tag; see this section's overview for how the sudoers files combine.
