服务器软防ddos_服务器防火墙软件

防火墙是什么

所谓防火墙是指一种将内部网和公众访问网分开的方法，实际上是一种建立在现代通信网络技术和信息安全技术基础的应用性安全技术，隔离技术。

防火墙分两种类型，一种是基于硬件的：叫做硬件防火墙，简称硬防；另一种是基于软件的：叫做软件防火墙，简称软防。

硬防：即硬件防火墙，是指把防火墙程序做到芯片里面，由硬件执行这些功能，能减少CPU的负担，使路由更稳定。它是保障内部网络安全的一道重要屏障。它的安全和稳定，直接关系到整个内部网络的安全。因此，日常例行的检查对于保证硬件防火墙的安全是非常重要的。

软防：软防就是软件防火墙，系统中存在的很多隐患和故障在暴发前都会出现这样或那样的苗头，例行检查的任务就是要发现这些安全隐患，并尽可能将问题定位，方便问题的解决。

简单的服务器使用介绍：长期使用服务器架设游戏，架设网站，要定期的进行数据备份，数据保存。服务器被攻击，这边尽量选择高防护的服务器，现在国内的机器防护基本是100G起。一般主要攻击主要是UDP CC 攻击，这些攻击不好防护，找好对应机房的防护策略，要机房做好对应的防护机器，当然机房的防护能力也很重要，机房会针对您业务端口加防护加策略防止服务器入侵的方式很简单，定期服务器杀毒，然后修改复杂密码，安装防护软件。这三种也有防范作用，但是对于技术高超的黑客来说，再好的防护也没用。
