阿里云windows服务器安全设置(防火墙策略)

通过防火墙策略限制对外扫描行为

请您根据您的服务器操作系统，下载对应的脚本运行，运行后您的防火墙策略会封禁对外发包的行为，确保您的主机不会再出现恶意发包的情况，为您进行后续数据备份操作提供足够的时间。

上述文件下载到机器内部直接执行即可。

设置iptables，限制访问

/sbin/iptables -P INPUT ACCEPT
/sbin/iptables -F
/sbin/iptables -X
/sbin/iptables -Z

/sbin/iptables -A INPUT -i lo -j ACCEPT
/sbin/iptables -A INPUT -p tcp --dport 22 -j ACCEPT
/sbin/iptables -A INPUT -p tcp --dport 80 -j ACCEPT
/sbin/iptables -A INPUT -p tcp --dport 8080 -j ACCEPT
/sbin/iptables -A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT
/sbin/iptables -A INPUT -m state --state ESTABLISHED -j ACCEPT
/sbin/iptables -P INPUT DROP
 service iptables save

以上脚本，在每次重装完系统后执行一次即可，其配置会保存至/etc/sysconfig/iptables
