无线网络在很大程度上突破了有线网络的限制,使用户获得了可移动性和方便性,但正因如此无线网络也面临更大的安全威胁,要求我们有更高一级的安全防范意识和防范措施,根据不同的安全需要,对无线网络的固有物理特性和组网结构进行透彻的分析,在不同的层面采取恰当的措施,保障无线网络的安全可用是完全可行的。 The wireless network has largely broken the wired network restrictions, allowing users to gain the mobility and convenience, but because of this wireless network also faces greater security threats, requiring us to have a higher level of security awareness And precautionary measures. According to different security needs, we thoroughly analyze the inherent physical characteristics and network structure of the wireless network. It is absolutely feasible to take appropriate measures at different levels to ensure the safe and available wireless network.
