Protocol, Transfer
protocol
Small lexicon of routers
Devices that communicate with each other must use the same rules. They
have to "speak the same language". Such rules and standards are called
protocols or transfer protocols. Frequently used protocols include IP, TCP,
PPP, HTTP and SMTP. TCP/IP is the umbrella term for all protocols that are
based on IP.
Service provider Supplier, company or institution that gives users access to the Internet or to
an online service.
Spoofing, Anti-
Spoofing
SNMP
In Internet terminology, spoofing means to specify a forged address. The
forged Internet address is used to pose as an authorised user.
Anti-spoofing means mechanisms to reveal or prevent spoofing.
SNMP (Simple Network Management Protocol) is a widespread mechanism
for the central control of network components such as servers, routers,
switches, printers, computers etc.
SNMP defines the communication process and the structure of the data
packages. UDP via IP is used for the transport.
SNMP does not define the values which can be read or changed.
This is done in an MIB (Management Information Base). The MIB is a
description file in which the individual values are listed in a table. The MIB is
for specific network components or for a class of components, such as
switches.
SNMP Trap SNMP trap is a message which is sent unprompted by the SNMP agent
(Simple Network Management Protocol) from a network component.
SSH
Symmetric
encryption
SSH (Secure SHell) is a protocol that enables secure, encrypted data
exchange between computers. Secure SHell is used for remote access to
the input console from LINUX-based machines.
With symmetric encryption, data is encrypted and decrypted with the same
key. DES and AES are two examples of symmetric encryption algorithms.
They are fast, but time-consuming to administer as the number of users
increases.
