0x00 前言简述
本人从事安全运维方面的工作（PS:曾经做过等保等方面的安全服务），由于最近单位在做等保测评，所以自然而然的与信安的测评人员一起对接相关业务系统的检查，在做主机系统测评检查时发现了系统中某些配置不符合等保要求，需要对不满足要求的主机做进一步整改，好在我们众多的系统基本都是运行在虚拟机上搭建的kubernetes集群中，这样一来就可以尽可能减少加固系统给应用带来的影响，我们可以一台一台加固更新。
在这样环境的驱动下不得不将通宵熬夜，我准备好了枸杞和保温杯，当然也把测试环境也准备了一套，并将以前写的安全加固脚本进行重新整理，根据当前业务服务器系统版本进行更新和测试。（我还年轻，我还可加班！）
我们企业内部主要有WindowsServer2019、CentOS7、以及Ubuntu20.04三类操作系统，可以看出操作系统版本都还是比较新的，所以在下面的安全配置核查脚本以及安全加固脚本主要针对上述的三个版本的操作系统。
Linux 系统中采用Shell脚本、WiindowsServer系统中采用的是PowerShell脚本。

0x01 WindowServer2019 配置核查与安全加固
Windows Server 安全配置策略基线加固项
- 系统账号策略
- 系统事件审核策略
- 系统组策略安全选项策略
- 注册表相关安全策略
- 防火墙服务相关安全策略
- 针对于系统暂无办法通过注册表以及组策略配置的安全加固项
- 从微软安全中心拉取服务器安全补丁列表信息与本地已打补丁做比较
废话不多，上才艺（脚本 ）

.SYNOPSIS
Windows Server 安全配置策略基线检测脚本 （脚本将会在Github上持续更新）
.DESCRIPTION
Windows Server 操作系统配置策略核查 (符合等保3级的关键检查项)
.EXAMPLE
WindowsSecurityBaseLine.ps1 -Executor WeiyiGeek -MsrcUpdate False
- Executor : 脚本执行者
- MsrcUpdate : 是否在线拉取微软安全中心的服务器安全补丁列表信息(建议一台主机拉取好之后将WSUSList.json和WSUSListId.json拷贝到当前脚本同级目录下)
.NOTES
注意:不同的版本操作系统以下某些关键项可能会不存在会有一些警告(需要大家提交issue，共同完成)。

function InstallDocker(){
# 1.卸载旧版本
sudo apt-get remove docker docker-engine docker.io containerd runc
# 2.更新apt包索引并安装包以允许apt在HTTPS上使用存储库
sudo apt-get install -y \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common
# 3.添加Docker官方GPG密钥 # -fsSL
sudo curl https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
# 4.通过搜索指纹的最后8个字符进行密钥验证
sudo apt-key fingerprint 0EBFCD88
# 5.设置稳定存储库
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
# 6.Install Docker Engine 默认最新版本
sudo apt-get update && sudo apt-get install -y docker-ce=5:20.10.7~3-0~ubuntu-focal docker-ce-cli=5:20.10.7~3-0~ubuntu-focal containerd.io docker-compose
# - 强制IPv4
# sudo apt-get -o Acquire::ForceIPv4=true install -y docker-ce=5:19.03.15~3-0~ubuntu-focal docker-ce-cli=5:19.03.15~3-0~ubuntu-focal containerd.io docker-compose
# 7.安装特定版本的Docker引擎，请在repo中列出可用的版本
apt-cache madison docker-ce
# docker-ce | 5:20.10.6~3-0~ubuntu-focal| https://download.docker.com/linux/ubuntu focal/stable amd64 Packages
# docker-ce | 5:19.03.15~3-0~ubuntu-focal | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages
# 使用第二列中的版本字符串安装特定的版本，例如:5:18.09.1~3-0~ubuntu-xenial。
# $sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io
#8.将当前用户加入docker用户组然后重新登陆当前用户使得低权限用户
sudo gpasswd -a ${USER} docker
# sudo gpasswd -a weiyigeek docker
#9.加速器建立
mkdir -vp /etc/docker/
sudo tee /etc/docker/daemon.json <<-'EOF'

第一次投稿给安全客，心里还是有点小激动的，在投稿时让我想起曾经深夜挖洞的过往，不知不觉已过几年了，颇多的感慨，仰望众多大佬的脚步前行，勿忘初心、不骄不躁。
后续我将针对 数据库应用软件以及中间件方面的等保测评项进行搜寻整理，编写安全加固配脚本供大家使用，争取再搞一个系列。
文章中脚本如有错误，欢迎各位大佬指正。
