Section 17: Book Chapter 20 - Wireless Networking
TKIP is ___ and AES is ___
WPA & WPA2 (Wi-Fi Protected Access)
What is a PoE injector?
A device which uses PoE to transmit electrical power over Ethernet cables.
If you spot a WAP on the ceiling of a large room with no obvious power outlet nearby, how is it most-likely powered? A. PoE B. RADIUS C. Battery D. Solar
A. PoE (Power over Ethernet)
Which is not a wireless encryption standard? A. WEP B. WPA C. WEP2 D. WPA2
C. WEP2
What is the Rate Limit?
Can limit the upstream or downstream of a specific WAP (Wireless Access Point)
What are two WAP's sharing the same SSID known as?
ESSID's
What is EAP (Extensible Authentication Protocol)?
A protocol that enables systems to use hardware-based identifiers, such as fingerprint scanners or smart card readers, for authentication.
What is RC4?
An RC stream cipher that will accept keys up to 128 bits in length.
What is an ESSID?
Extended Service Set Identifier - Name for a set of wireless base stations, all with the same name.
WPA 2
Implements all of the IEEE 802.11i standards
What is WPA (Wi-Fi Protected Access)?
Security standard that improves on older security standards by authenticating network users and providing more advanced encryption techniques; generally used for wireless communications
What is TACACS+?
TACACS+ is a Cisco Proprietary protocol that enables AAA. Uses TCP port 49 for communication. Very Secure.
What is a Captive Portal?
Technical solution that forces clients using web browsers to complete a specific process before it allows them access to the network.
What is the 802.11i standard?
The IEEE standard for wireless network encryption and authentication that uses the EAP (Extensible Authentication Protocol) authentication method, strong encryption, and dynamically assigned keys, which are different for every transmission. 802.11i specifies AES encryption and weaves a key into each packet.
What is WEP (Wired Equivalent Privacy)?
Wired Equivalent Privacy - A key encryption technique for wireless networks that uses keys both to authenticate network clients and to encrypt data in transit.
What is Power over Ethernet (PoE)?
A feature that might be available on high-end wired network adapters that allows power to be transmitted over Ethernet cable to remote devices.
What is WPS (Wi-Fi Protected Setup)?
A feature with many wireless devices that allows users to configure wireless security with a push button or a PIN. When enabled, it is vulnerable to attacks using free open source software. Very user friendly but not very secure.
What is a RADIUS server?
A server that offers centralized authentication services to a network's access server, VPN server, or wireless access point via the RADIUS protocol.
What is AES (Advanced Encryption Standard)?
An encryption standard used by WPA2 and is currently the strongest encryption standard used by Wi-Fi.
What is AAA?
Authorization, Authentication, and Accounting
What is TKIP (Temporal Key Integrity Protocol)?
Deprecated encryption standard that provided a new encryption key for every sent packet. A security protocol created by the IEEE 802.11i task group to replace WEP.
What is a Personal/Pre-shared Key (PSK)?
It is a password for your wireless network that has a key created by the user in charge of the network/business and gives the password out individually to people who need to use it.
What do you use to determine WAP location?
Powerful wireless analysis tools
What protocols do enterprise networks often use for authentication?
RADIUS TACACS+
