CIS 基准测试未通过主机配置测试

添加以下 docker 工件的审核规则后：

$ sudo auditctl -l
-w /usr/bin/dockerd -p rwxa -k docker
-w /var/lib/docker -p rwxa -k docker
-w /etc/docker -p rwxa -k docker
-w /lib/systemd/system/docker.service -p rwxa -k docker
-w /lib/systemd/system/docker.socket -p rwxa -k docker
-w /etc/default/docker -p rwxa -k docker
-w /etc/docker/daemon.json -p rwxa -k docker
-w /usr/bin/docker-containerd -p rwxa -k docker
-w /usr/bin/docker-runc -p rwxa -k docker
$

CIS 基准实用程序（https://github.com/docker/docker-bench-security）不通过：

$ sudo ./docker-bench-security.sh -c tests/1_host_configuration.sh

我正在使用Ubuntu 18.04，并且已在文件中添加了所有规则/etc/audit/rules.d/audit.rules，并且工作正常。

对于CentOS 6，文件位于/etc/audit/audit.rules。
