Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network.
Internet users use eavesdropping via the Internet to improve information security. [2] A typical network eavesdropper may be called a Black-hat hacker and is considered a low-level hacker as it is simple to network eavesdrop successfully. [1] The threat of network eavesdroppers is a growing concern.
A "soft access point" (soft AP) can be set up on a Wi-Fi adapter using for example Windows' virtual Wi-Fi or Intel's My WiFi. This makes it possible, without the need of a physical Wi-Fi router, to share the wired network access of one computer with wireless clients connected to that soft AP.
These include design flaws in the Wi-Fi standard, affecting most devices, and programming errors in Wi-Fi products, making almost all Wi-Fi products vulnerable. The vulnerabilities impact all Wi-Fi security protocols, including WPA3 and WEP. Exploiting these flaws is complex but programming errors in Wi-Fi products are easier to exploit.
Some wireless networking devices may not support the latest security mechanisms, and users must therefore leave their network unsecured. For example, the Nintendo DS and Nintendo DS Lite can only access wireless routers using the discredited WEP standard, however, the Nintendo DSi and Nintendo 3DS both support WPA encryption.
An evil twin is a fraudulent Wi-Fi access point that appears to be legitimate but is set up to eavesdrop on wireless communications. [1]This type of attack, also known as a man-in-the-middle attack, may be used to steal the passwords of unsuspecting users, either by monitoring their connections or by phishing, which involves setting up a fraudulent web site and luring people there.
A wireless intrusion detection system (WIDS) monitors the radio spectrum for the presence of unauthorized, rogue access points and the use of wireless attack tools. The system monitors the radio spectrum used by wireless LANs, and immediately alerts a systems administrator whenever a rogue access point is detected.
