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.
Screenshot of Android Wi-Fi configuration with the Security set to "Enhanced Open" Opportunistic Wireless Encryption (OWE) is a Wi-Fi standard which ensures that communication between a public hotspot and end devices is protected from other end devices. In contrast to conventional public hotspots, the data is transmitted in encrypted form.
The WPS protocol defines three types of devices in a network: Registrar A device with the authority to issue and revoke access to a network; it may be integrated into a wireless access point (AP), or provided as a separate device. Enrollee A client device seeking to join a wireless network. AP An access point functioning as a proxy between a ...
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
Inter-Access Point Protocol or IEEE 802.11F is a recommendation that describes an optional extension to IEEE 802.11 that provides wireless access point communications among multivendor systems. [ 1 ] 802.11 is a set of IEEE standards that govern wireless networking transmission methods.
An infrastructure BSS is created by an infrastructure device called an access point (AP) for other devices to join. (Note that the term IBSS is not used for this type of BSS but refers to the independent type discussed below.) The operating parameters of the infrastructure BSS are defined by the AP. [3]
When a device leaves the network, the GTK also needs to be updated. This is to prevent the device from receiving any more multicast or broadcast messages from the AP. To handle the updating, 802.11i defines a Group Key Handshake that consists of a two-way handshake: The AP sends the new GTK to each STA in the network.
