MD5
(Message Direct algorithm 5) A one-way hashing algorithm used in many
authentication algorithms to derive cryptographic keys. MD5 takes a message of
an arbitrary length and creates a 128-bit message digest. See also,
authentication.
MIB
(Management Information Base) A set of parameters an SNMP management
station can query or establish in the SNMP agent of a network device (for
example, a router). Standard minimal MIBs have been defined, and vendors
often have their own private enterprise MIBs. In theory, any SNMP manager can
talk to any SNMP agent with a properly defined MIB. See also, SNMP and
station.
MS-CHAP
(Microsoft Challenge Handshake Authentication Protocol) Microsoft's extension
to CHAP. MS-CHAP is a mutual authentication protocol that also permits a
single login in a Microsoft network environment. See also, connectivity.
NAT
(Network Address Translation) RFC 3022 defines a way to translate global
routable IP addresses into local and private non-routable ones.
NTP
(Network Time Protocol) An Internet standard protocol (built on top of TCP/IP)
that ensures the accurate synchronization (to the millisecond) of computer clock
times in a network of computers. NTP synchronizes client workstation clocks to
the U.S. Naval Observatory master clocks in Washington, D.C. and Colorado
Springs, CO. Running as a continuous background client program on a
computer, NTP sends periodic time requests to servers, obtaining server time
stamps and using them to adjust the client's clock. See also, SNTP.
Odyssey
An 802.1X security and access control application for wireless LANs (WLANs),
developed by Funk Software, Inc. See also, 802.1X.
