As Wi-Fi continues to spread, its security issues are highlighted. 802.11 is the wireless LAN standard established by IEEE. Wi-Fi is a commercial 802.11 standard. Because the Wi-Fi Alliance early no mature security mechanism, resulting in the spread of the net people.
This article provides security analysis for the hidden SSID mac binding WEP WPA WPA2 and its Enterprise edition. Because the Wi-Fi Alliance early no mature security mechanism, resulting
keys, and more authentication mechanisms to provide a higher level of security. In the area of user authentication, 802.1X client authentication requests can also be authenticated by an external RADIUS server. The certification belongs to the transition period method and each vendor realizes the different methods, which directly cause the compatibility problem.
This approach requires expertise deployment and RADIUS server support, which is expensive and is typically used for enterprise wireles
wireless data, you should use a more secure encryption method, such as WPA. To help you understand these options, here are some of the existing wireless encryption methods and security technologies: · WEP (Wired Equivalent protocol). WEP is an encryption method that is used by some manufacturers eager to produce wireless devices to hastily piece together fake encryption standards before protocol standards are finalized. As a result, this standard lat

Then add the following lines to the file:Iface wlan0 inet staticaddress 192.168.42.1netmask 255.255.255.0Gateway 192.168.1.1The bottom half of the file would now look something like this:Allow-hotplug Wlan0#iface Wlan0 inet Manual#wpa-conf/etc/wpa_supplicant/wpa_supplicant.confIface wlan0 inet staticaddress 192.
login usernames and passwords. The factory usernames and passwords of wireless ADSL cats of the same model and manufacturer are the same, you can also enter the username and password modification option of the wireless ADSL cat, and change it to your easy-to-remember username or password.
In addition, the security protection of wireless ADSL cats can be more "automatic", for example, WEP/WPA encryption or MAC address filtering to further improve secu

WPA is a subset of 802.11i. It fixes WEP vulnerabilities by changing keys and hybrid keys, it also uses 802.1x and Its Extended Authentication Protocol (EAP) based on a central authentication server such as Radius 。

With the increasing popularity of Wi-Fi, security issues have also been highlighted. 802.11 is a wireless LAN standard developed by IEEE. Wi-Fi is a commercial standard of 802.11. Due to the lack of mature security mechanisms in the early days of the Wi-Fi Alliance, the network hit flood occurs.This document analyzes the security of MAC-bound wep wpa WPA2 and its Enterprise Edition. Due to the lack of mature security mechanisms in the early days of th
HOSTAPD and WPA_SUPPLICANTHOSTAPDHOSTAPD includes IEEE 802.11 access point Management (Authentication/association), IEEE 802.1X/WPA/WPA2 Authenticato R, EAP server, and RADIUS authentication server functionality. It can be build with various configuration option, e.g., a standalone AP management solution or a RADIUS authentication se RVer with support for number of EAP methods.The design goal for HOSTAPD is to use hardware, driver, and OS Independent,

But on Mac OSX and Linux, Kismet can be compatible with many wireless cards.Third, WiFi AnalyzerWiFi Analyzer is a free Android app that can be used to search for AP hotspots on Android tablets and Android phones. WIFI Analyzer can display AP specific information on the 2.4GHz band, as well as devices on some 5G bands. You can send the AP information list (XML file) to the mailbox or other programs, or to the screen, WiFi Analyzer can graphically display the signal streng

It lists all the details of the ap in the GHz channel and supports other devices in the 5 GHz channel. You can also share AP details in XML format by email or other applications or screenshots. It is
