1.无线加密
首先我们来说一下无线加密(U盘加密:http://www.kkzj.com/)吧,这是目前最为常见的保护方式,主要是通过无线路由器的WEB界面,进行无线网络加密设置。AP或无线路由器的加密类型目前有两种,64位和128位加密类型,用户可以分别输入10个或26个字符串的加密密码来对无线网络进行保护。这里需要提醒大家的一点是,在出厂时无线路由器的无线加密功能都是关闭的,如果你拿来直接使用的话,那么你的网络就是极度不安全的,因此建议大家先设置好无线路由器的加密功能。另外,也建议大家设置密码时最好包含字符、数字、公式以及汉字等,这样的密码安全系数会比较高。
2.关闭DHCP服务器
DHCP的主要功能是让电脑自动分配IP地址给局域网,这样可以免去用户自己动手设置IP子网掩码、地址以及其他所需要的TCP/IP参数。不过由于DHCP功能是开启的,这意味着只要在任何能覆盖信号的范围内的电脑都可以获取IP地址,而非法用户的非法连接则会给无线网络带来了安全隐患。因此,禁用DHCP功能是一种较为有效的安全防护措施。
3.开启IP地址、IPMAC地址过滤
启用无线路由器的IP地址过滤功能后,只有IP地址在列表中的用户才能正常访问无线网络,不在列表的用户就无法连入网络了。不过要注意的一点,在“过滤规则”中要选择“仅允许已设MAC地址列表中已生效的MAC地址访问无线网络”选项,否则的话无线路由器会对所有用户连入网络的用户都进行阻止,
此外,在无线局域网中禁用了DHCP功能的,建议为使用无线服务的电脑都设置一个固定的IP地址,然后将这些IP地址都输入IP地址允许列表中。这样就可以有效的保护无线网络的安全了。
4.禁用SSID广播
简单的来讲SSID,就是你为你的无线网络所起的名字,由于同一厂商出厂的产品所用的SSID是一样的,这就让一些人有机可乘,他们可以通过初始字符串的方式来非法入侵你的无线网络,大大降低了你的无线网络的安全系数。因此把SSID广播功能关闭是很必要的。
这里要大家注意的一点是,关闭SSID广播不会影响使用,只是会让其他人的搜索信号菜单不显示你的SSID名。在信号搜索菜单中无法找到你的无线网络,也就可以有效避免非法用户入侵。
在这个科技信息发达的时代,无线网络的安全变得越来愈重要了。不少公司或者个人都把无线网络安全问题放在了首要的位置。所以学会以上四招来保证我们无线网络的安全是非常有必要的。
