Ensure password fields are not empty

高レベル 1自動ros

説明

An account with an empty password field means that anybody may log in as that user without providing a password. The audit requires every account in /etc/shadow to have a non-empty password field. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

修正方法

修正方法: ガイダンスまたは IaC パッチ

If any accounts in the /etc/shadow file do not have a password, run the following command to lock the account until it can be determined why it does not have a password: # passwd -l <username> Also, check to see if the account is logged in and investigate what it is being used for to determine if it needs to be forced off.
