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

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

    $blacklist = ["\$_", "eval","copy" ,"assert","usort","include", "require", "$", "^", "~", "-", "%", "*","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;
}
