Ensure authentication required for single user mode

中级别 1自动化ros

说明

Single user mode is used for recovery when the system detects an issue during boot or by manual selection from the bootloader. The audit requires the root account to have a password set in /etc/shadow, so single-user mode asks for it. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

检查方式

审计方法: Shell 命令

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁
