Layer for the Transport Layer, using asymmetric cryptography
for key exchange, symmetric encryption for confidentiality, and
message authentication codes for message integrity.
Syslog
Syslog is a standard for computer data logging. Syslog can be
used for computer system management and security auditing as
well as generalized informational, analysis, and debugging
messages
TCP
Transmission control protocol. The most common transport
layer protocol used on Ethernet and the Internet.
TCP/IP
Transmission control protocol over Internet Protocol. The de
facto standard Ethernet protocols incorporated into 4.2BSD
Unix. TCP/IP was developed by DARPA for Internet working
and encompasses both network layer and transport layer
protocols. While TCP and IP specify two protocols at specific
protocol layers, TCP/IP is often used to refer to the entire US
Department of Defense protocol suite based upon these,
including Telnet, FTP, UDP and RDP.
UDP
The User Datagram Protocol (UDP) is one of the core members
of the Internet protocol suite. With UDP, computer applications
can send messages, in this case referred to as datagrams, to
other hosts on an Internet Protocol (IP) network without prior
communications to set up special transmission channels or data
paths.
UMT
User management tool
UTC
Coordinated Universal Time. A coordinated time scale,
maintained by the Bureau International des Poids et Mesures
(BIPM), which forms the basis of a coordinated dissemination
of standard frequencies and time signals. UTC is derived from
International Atomic Time (TAI) by the addition of a whole
number of "leap seconds" to synchronize it with Universal
Time 1 (UT1), thus allowing for the eccentricity of the Earth's
orbit, the rotational axis tilt (23.5 degrees), but still showing the
Earth's irregular rotation, on which UT1 is based. The
Coordinated Universal Time is expressed using a 24-hour
clock, and uses the Gregorian calendar. It is used for aeroplane
and ship navigation, where it is also sometimes known by the
military name, "Zulu time." "Zulu" in the phonetic alphabet
stands for "Z", which stands for longitude zero.
VPN
A Virtual Private Network (VPN) extends a private network
across public networks like the Internet. It enables a host
computer to send and receive data across shared or public
networks as if it were a private network with all the
functionality, security and management policies of the private
network.
