set of addresses for external traffic.
Network Time Protocol (NTP)
A protocol that lets devices synchronize their time with a time server. NTP uses TCP or UDP port
123 by default.
Passphrase
A text string that automatically generates WEP keys on wireless client adapters.
Power Over Ethernet (PoE)
A PoE provides power to PoE‐enabled devices using an 8‐pin CAT 5 Ethernet cable, eliminating the
need for a power source.
Preamble
Synchronizes transmissions in a WLAN. The preamble type defines the length of the Cyclic
Redundancy Check block for communication between a device and roaming wireless stations.
Protected Extensible Authentication Protocol (PEAP)
Authentication protocol of IEEE 802.1x used to send authentication data and passwords over
802.11 WLANs.
Quality of Service (QoS)
A network's ability to deliver data with minimum delay. QoS also refers to the networking
methods used to provide bandwidth for real‐time multimedia applications.
Remote Authentication Dial‐In User Service (RADIUS)
Networking protocol that provides centralized authentication, authorization, and accounting
management for computers to connect and use a network service. Because of its broad support
and ubiquitous nature, the RADIUS protocol is often used by ISPs and enterprises to manage
access to the Internet or internal networks, WLANs, and integrated e‐mail services.
Service Set Identifier (SSID)
Name of a WLAN. All wireless devices on a WLAN must use the same SSID to communicate with
each other.
Simple Network Management Protocol (SNMP)
An Internet‐standard protocol for managing devices on IP networks.
Snooping
Passively watching a network for data, such as passwords, that can be used to benefit a hacker.
Temporal Key Integrity Protocol (TKIP)
An encryption protocol that uses 128‐bit keys. Keys are dynamically generated and distributed by
the authentication server. TKIP regularly changes and rotates encryption keys, with an encryption
key never being used twice.
Transmission Control Protocol/Internet Protocol (TCP/IP)
A protocol that allows communications over and between networks. TCP/IP is the basis for
Internet communications.
