Chapter 5 Terms

Security+ SY0-501 7th Edition Terms (Chapter 5)

802.1x The IEEE standard that defines port-based security for wireless network access control.
access point (AP) The point at which access to a network is accomplished. This term is often used in relation to a wireless access point (WAP).
bluejacking The sending of unsolicited messages over a Bluetooth connection.
bluesnarfing The gaining of unauthorized access through a Bluetooth connection.
disassociation An attack in which the intruder sends a frame to the AP with a spoofed address to make it look like it came from the victim and disconnects them from the network.
evil twin An attack in which a rogue wireless access point poses as a legitimate wireless service provider to intercept information that users transmit.
interference The byproduct of electrical processes. One common form of interference is Radio Frequency Interference (RFI), which is usually projected across a radio spectrum.
IV attack An attack that involves looking at repeated results in order to crack the WEP secret key.
jamming Purposely obstructing or interfering with a signal.
near field communication (NFC) Technology that enables communication between devices when they’re “touched” together. Often used to verify (often through RFID or Wi-Fi) that the device is present.
radio frequency identification (RFID) A technology that incorporates the use of electromagnetic coupling in the radio frequency (RF) portion of the spectrum to identify items uniquely (object, animal, person, credit cards, door access tokens, antishoplifting devices, and so on).
replay attack An attack that captures portions of a session to play back later to convince a host that it is still talking to the original connection.
rogue access point An unauthorized wireless access point on a network.
SSID The Service Set Identifier (SSID) is used by the access point of a wireless LAN to identify itself and is intended to be unique for a particular area/entity on a network.
Wi-Fi A wireless network operating in the 2.4 GHz or 5 GHz range.
Wi-Fi Protected Setup (WPS) An authentication process that requires the user to do something in order to complete the enrollment process. Examples include pressing a button on the router within a short time period, entering a PIN, or bringing the new device close.
Wired Equivalent Privacy (WEP) A security protocol for 802.11b (wireless) networks that attempts to establish the same security for them as would be present in a wired network.
wireless access point A connection device used for clients in a radio frequency (RF) network.
Wi-Fi Protected Access version 2 (WPA2) The 802.11i standard. It is an enhancement to earlier standards, which were much weaker.
