Ensure password fields are not empty

高等級 1自動化ros

說明

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.

檢查方式

稽核方法: Shell 指令

shell

[ -r /etc/shadow ] || exit 1

修補方式

修補方法: 操作指南或基礎設施修補檔

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.
