Ensure the Sudo Timeout Period Is Set to Zero

高级别 1自动化macos

说明

The sudo command allows the user to run programs as the root user. Working as the root user allows the user an extremely high level of configurability within the system. This control, along with the control to use a separate timestamp for each tty, limits the window where an unauthorized user, process, or attacker could utilize legitimate credentials that are valid for longer than required. Audit: Requires a 0.0 minute sudo timestamp timeout and /etc/sudoers.d owned by root:wheel. Run as root.

检查方式

审计方法: Shell 命令

shell

v=$(/usr/bin/sudo -V 2>/dev/null) || exit 1
c=$(printf '%s\n' "$v" | /usr/bin/grep -c "Authentication timestamp timeout: 0.0 minutes")
o=$(/usr/bin/stat -f '%Su:%Sg' /etc/sudoers.d 2>/dev/null)
if [ "$c" -ge 1 ] && [ "$o" = root:wheel ]; then echo compliant; else echo "timeout-zero=$c owner=$o"; fi

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁
