dmz是啥意思？
DMZ是英文“demilitarized zone”的缩写，中文名称为“隔离区”，也称“非军事化区”。它是为了解决安装防火墙后外部网络不能访问内部网络服务器的问题，而设立的一个非安全系统与安全系统之间的缓冲区，这个缓冲区位于企业内部网络和外部网络之间的小网络区域内，在这个小网络区域内可以放置一些必须公开的服务器设施，如企业Web服务器、FTP服务器和论坛等。另一方面，通过这样一个DMZ区域，更加有效地保护了内部网络，因为这种网络部署，比起一般的防火墙方案，对攻击者来说又多了一道关卡。 网络设备开发商，利用这一技术，开发出了相应的防火墙解决方案。称“非军事区结构模式”。DMZ通常是一个过滤的子网，DMZ在内部网络和外部网络之间构造了一个安全地带。 DMZ防火墙方案为要保护的内部网络增加了一道安全防线，通常认为是非常安全的。同时它提供了一个区域放置公共服务器，从而又能有效地避免一些互联应用需要公开，而与内部安全策略相矛盾的情况发生。在DMZ区域中通常包括堡垒主机、Modem池，以及所有的公共服务器，但要注意的是电子商务服务器只能用作用户连接，真正的电子商务后台数据需要放在内部网络中。 在这个防火墙方案中，包括两个防火墙，外部防火墙抵挡外部网络的攻击，并管理所有内部网络对DMZ的访问。内部防火墙管理DMZ对于内部网络的访问。内部防火墙是内部网络的第三道安全防线(前面有了外部防火墙和堡垒主机)，当外部防火墙失效的时候，它还可以起到保护内部网络的功能。而局域网内部，对于Internet的访问由内部防火墙和位于DMZ的堡垒主机控制。在这样的结构里，一个黑客必须通过三个独立的区域(外部防火墙、内部防火墙和堡垒主机)才能够到达局域网。攻击难度大大加强，相应内部网络的安全性也就大大加强，但投资成本也是最高的。
“网络攻击”用英语怎么说
网络攻击：利用网络存在的漏洞和安全缺陷对网络系统的硬件、软件及其系统中的数据进行的攻击。
英文翻译：network attack;
ARP是什么意思?
简单来说就是有个机子中了病毒,它伪造IP地址和你冲突,或是伪造网关,便你的计算机不能正常的接收数据,从而掉线
ARP（AddressResolutionProtocol）地址解析协议用于将计算机的网络IP地址转化为物理MAC地址。ARP协议的基本功能就是通过目标设备的IP地址，查询目标设备的MAC地址，以保证通信的顺利进行。在每台安装有TCP/IP协议的电脑里都有一个ARP缓存表，表里的IP地址与MAC地址是一一对应的，如果系统ARP缓存表被修改不停的通知路由器一系列错误的内网IP或者干脆伪造一个假的网关进行欺骗的话，网络就肯定会出现大面积的掉线问题。ARP攻击在现今的网络中频频出现，有效的防范ARP形式的网络攻击已成为确保网络畅通必要条件。
英文原义：Address
Resolution
Protocol
中文释义：（RFC-826）地址解析协议
局域网中，网络中实际传输的是“帧”，帧里面是有目标主机的MAC地址的。所谓“地址解析”就是主机在发送帧前将目标IP地址转换成目标MAC地址的过程。ARP协议的基本功能就是通过目标设备的IP地址，查询目标设备的MAC地址以保证通信的顺利进行。
注解：简单地说，ARP协议主要负责将局域网中的32为IP地址转换为对应的48位物理地址，即网卡的MAC地址，比如IP地址为192.168.0.1网卡MAC地址为00-03-0F-FD-1D-2B。整个转换过程是一台主机先向目标主机发送包含IP地址信息的广播数据包，即ARP请求，然后目标主机向该主机发送一个含有IP地址和MAC地址数据包，通过MAC地址两个主机就可以实现数据传输了。
应用：在安装了以太网网络适配器的计算机中都有专门的ARP缓存，包含一个或多个表，用于保存IP地址以及经过解析的MAC地址。在Windows中要查看或者修改ARP缓存中的信息，可以使用arp命令来完成，比如在Windows
XP的命令提示符窗口中键入“arp
-a”或“arp
-g”可以查看ARP缓存中的内容；键入“arp
-d
IPaddress”表示删除指定的IP地址项（IPaddress表示IP地址）。arp命令的其他用法可以键入“arp
/?”查看到.
