wazuh环境配置

1.进入官网下载OVA启动软件

Virtual Machine (OVA) - Installation alternatives (wazuh.com)

2.进入VMware像配置其他虚拟机一样进行配置即可

3.上面会有提示：账号为，wazuh-user；密码，wazuh

4，将网络连接模式更改为NAT，否则不能连上网

5.重启网络，查看ip 连接xshell

service network restart

ip addr

6 .开启小皮Apache，输入ip进行访问，我在Microsoft不能访问，所以用的Firefox进行访问成功，然后登录wazuh，用户名和密码默认为admin

注意如果没有出现下面图则重启一下wazuh

systemctl restart wazuh-manager

案例复现
wazuh初体验理解

当我们使用本地的cmd通过ssh一直连接wazuh的时候便会出现十级报错，此次在后台可以明显的看到有爆破的提示扫描，通过分析其具体的数据包以及对应的规则理解到wuzuh在外来访问的时候，会触发到解码器，其作用是用来抓取关键信息，其中核心便是正则表达式进行正则匹配，当数据来了之后，wazuh程序会分析我们的日志，把这些日志信息发到相对应的解码器去，通过解码器去进行解码，解码完后，再发送到相应的规则，然后把解码完的数据通过规则，再次进行匹配，最终展示到仪表盘的Modules里的Security events里

在Nginx目录下/var/www/html创建index.php并写入案例

<?php
function fun($var): bool{
$blacklist = ["\$_", "eval","copy" ,"assert","usort","include", "require", "$", "^", "~", "-", "%", "*","file","fopen","fwriter","fput","copy","curl","fread","fget","function_exists","dl","putenv","system","exec","shell_exec","passthru","proc_open","proc_close", "proc_get_status","checkdnsrr","getmxrr","getservbyname","getservbyport", "syslog","popen","show_source","highlight_file","`","chmod"];

foreach($blacklist as $blackword){
if(strstr($var, $blackword)) return True;
}

return False;
}
error_reporting(0);
//设置上传目录
define("UPLOAD_PATH", "./uploads");
$msg = "Upload Success!";
if (isset($_POST['submit'])) {
$temp_file = $_FILES['upload_file']['tmp_name'];
$file_name = $_FILES['upload_file']['name'];
$ext = pathinfo($file_name,PATHINFO_EXTENSION);
if(!preg_match("/php/i", strtolower($ext))){
die("只要好看的php");
}

$content = file_get_contents($temp_file);
if(fun($content)){
die("诶，被我发现了吧");
}
$new_file_name = md5($file_name).".".$ext;
$img_path = UPLOAD_PATH . '/' . $new_file_name;

if (move_uploaded_file($temp_file, $img_path)){
$is_upload = true;
} else {
$msg = 'Upload Failed!';
die();
}
echo '<div style="color:#F00">'.$msg." Look here~ ".$img_path."</div>";
}
