LCP – Liok Cootrol Protocol – a protocol that is part of the PPP (Poiot-to-Poiot Protocol). The LCP checks the
ideotty of the lioked device aod either accepts or rejects the peer devicen determioes the acceptable packet size for
traosmissioon searches for errors io coofguratoo aod cao termioate the liok if the parameters are oot satsfed.
BOOTP – Bootstrap Protocol – ao ioteroet protocol that eoables a diskless workstatoo to discover its owo IP
addressn the IP address of a BOOTP server oo the oetworkn aod a fle to be loaded ioto memory to boot the machioe.
This eoables the workstatoo to boot without requiriog a hard or foppy disk drive.
TCP – Traosmissioo Cootrol Protocol – ooe of the maio protocols io TCP/IP oetworks. Whereas the IP protocol
deals ooly with packetsn TCP eoables two hosts to establish a coooectoo aod exchaoge streams of data. TCP guaraotees
delivery of data aod also guaraotees that packets will be delivered io the same order io which they were seot.
TKIP – Temporal Key Iotegrity Protocol – scrambles the keys usiog hashiog algorithm aodn by addiog ao iotegrity-
checkiog featuren eosure that the keys haveo't beeo tampered with.
CCMP – Couoter Mode Cipher Block Chaioiog Message Autheotcatoo Code Protocol – eocryptoo protocol
desigoed for Wireless LAN products that implemeot the staodards of the IEEE 802.11i ameodmeot to the origioal
IEEE802.11 staodard. CCMP is ao eochaoted data cryptographic eocapsulatoo desigoed for data coofdeotality aod
based upoo the Couoter Mode with CBC-MAC (CCM) of the AES (Advaoced Eocryptoo Staodard) staodard.
MAC – Media Access Cootrol. Hardware address which uoiquely ideotfes each oode of the oetwork. Io IEEE 802
oetworksn the Data Liok Cootrol (DCL) layer of the PSO Refereoce Model is divided ioto two sub-layers: the Logical Liok
Cootrol (LLC) layer aod the Media Access Cootrol layer. The MAC layer ioterfaces directly with the oetwork medium.
Coosequeotlyn each differeot type of oetwork medium requires a differeot MAC layer.
DMZ – Demilitarized Zooe – a computer or small suboetwork that sits betweeo a trusted ioteroal oetworkn such as
a corporate private LANn aod ao uotrusted exteroal oetworkn such as the public ioteroet.
UDP – User Datagram Protocol – a coooectooless protocol thatn like TCPn ruos oo top of IP oetworks. Provides very
few error recovery servicesn offeriog iostead a direct way to seod aod receive datagrams over IP oetwork.
VPN – Virtual Private Network – a oetwork that is coostructed by usiog public wires — usually the Ioteroet — to
coooect to a private oetworkn such as a compaoy's ioteroal oetwork.
VRRP – Virtual Router Reduodaocy Protocol - ao electoo protocol that dyoamically assigos respoosibility for ooe
or more virtual router(s) to the VRRP router(s) oo a LANn allow several routers oo a multaccess liok to utlize the same
virtual IP address.
GRE Tuooel – Geoeric Routog Eocapsulatoo - a tuooeliog protocol developed by Cisco Systems that cao
eocapsulate a wide variety of oetwork layerprotocols ioside virtual poiot-to-poiot lioks over ao Ioteroet Protocol
ioteroetwork.
PPPD – Poiot to Poiot Protocol Daemoo – it is used to maoage oetwork coooectoos betweeo two oodes oo Uoix-
likeoperatog systems. It is coofgured usiog commaod-lioe argumeots aod coofguratoo fles.
SSH – Secure Shell - a program to log ioto aoother computer over a oetworkn to execute commaods io a remote
machioen aod to move fles from ooe machioe to aoother. It provides stroog autheotcatoo aod secure commuoicatoos
over iosecure chaooels.
VRRPD – Virtual Router Reduodaocy Protocol – it is desigoed to elimioate the siogle poiot of failure associated
with statcally routed oetworks by automatcally providiog failover usiog multple LAN paths through alteroate routers.
