TCP/IP
Name used for all traffic protocols used in the Internet (i.e. for IP, ICMP, TCP, UDP,
etc.). TCP/IP does not stand for any particular protocol!
TLS
Transport Layer Security. New version of SSL protocol. This version is approved by
the IETF and it is accepted by all the top IT companies (i.e. Microsoft Corporation).
UDP
User Datagram Protokol is a transmission protocol which transfers data through in-
dividual messages (so called datagrams). It does not establish new connections nor
it provides reliable and sequentional data delivery, nor it enables error correction
or data stream control. It is used for transfer of small-sized data (i.e. DNS queries)
or for transmissions where speed is preferred from reliability (i.e. realtime audio
and video files transmission).
VPN
Virtual Private Network, VPN represents secure interconnection of private networks
(i.e. of individual offices of an organization) via the Internet. Traffic between both
networks (so called tunnel) is encrypted. This protects networks from tapping.
VPN incorporates special tunneling protocols, such as Microsoft’s IPSec and PPTP
(Point-to-Point Tunnelling Protocol).
WinRoute contains a proprietary VPN implemetation called Kerio VPN.
