WiFi渗透与防御：筑牢网络安全防线

在当今数字时代，WiFi网络已成为现代生活的基石，为我们提供了便捷的网络连接，赋能了物联网设备。然而，与便利性并存的，是日益严重的网络安全隐患。

WiFi渗透：网络攻防中的关键环节

WiFi渗透技术是指攻击者利用WiFi网络的漏洞或弱点，获取未经授权的访问权限，从而窃取数据、破坏网络或发起其他恶意活动。了解WiFi渗透技术对于网络安全攻防演练至关重要，有助于企业和个人识别网络安全薄弱点，并采取相应的防御措施。

常见的WiFi渗透技术包括：

WPS暴力破解： 利用WPS协议的漏洞，通过不断尝试不同的PIN码来破解路由器的密码。
字典攻击： 攻击者使用包含常见密码的字典，对路由器的密码进行逐个尝试。
钓鱼攻击： 攻击者通过创建虚假WiFi热点，诱骗用户连接，并窃取用户的登录信息。
ARP欺骗： 攻击者通过向网络中的主机发送伪造的ARP回复，将自己冒充成其他合法主机，从而窃取数据或发起其他攻击。
DoS攻击： 攻击者通过向WiFi网络发送大量数据，使网络堵塞，导致合法用户无法正常访问网络。
