Glossary
* (asterisk character)
– The ‘wildcard’ character, used to signify “all within this group or function” (e.g,.
use * to specify all domain names). A special symbol that stands for one or more characters. Many
operating systems and applications support wildcards for identifying files and directories. This lets you
select multiple files with a single specification. For example, in DOS and Windows, the asterisk (*) is a
wild card that stands for any combination of letters.
: (colon character)
– The character used by the RouteFinder WebAdmin softtware for a port range. For
example, to enter the S-Port/Client source port number as a port range, enter 1024:64000.
, (comma character)
– The character used by the RouteFinder WebAdmin softtware for a series (list) of
port numbers. For example, to enter the S-Port/Client source port number as a list of port numbers, enter
25, 80, 110.
- (dash character)
– An acceptable RouteFinder WebAdmin entry field character. For example, from
VPN|IPSec configurations|New connection|Secret) you can enter a shared Secret using
alphanumeric characters, the dash (-) or the space or underline (_) characters.
_ (space or underscore character)
– An acceptable RouteFinder WebAdmin entry field character. For
example, from VPN|IPSec configurations|New connection|Secret) you can enter a shared Secret
using alphanumeric characters, the dash (-) or the space or underline (_) characters.
3DES (Triple Data Encryption Standard)
– The 3DES encryption algorithm combines three uses of
single DES with two keys, making the key size 112 bits. With the increase in size, 3DES is much more
secure than DES, but 3DES runs slower than DES. The RouteFinder supports up to 256 tunnels with
3DES encryption throughput of 15M bps (e.g., 3DES can be configured in WebAdmin from VPN|IPSEC
Configurations).
The RouteFinder uses 3DES as an encryption algorithm and not simple DES (Data Encryption Standard)
because simple DES is generally known to be insecure and out of date.
The RouteFinder default selection is 3des-md5-96 .
AES (Advanced Encryption Standard)
– The U.S. government statndard for data encryption.
Rijndael was chosen as the U.S. government encryption standard to protect sensitive data and to spur the
digital economy, replacing DES. The algorithms used by the Rijndael AES have since been adopted by
businesses and organizations worldwide.
Alias
–
A name, usually short and easy to remember, that is translated into another name, usually long
and difficult to remember.
Anonymous FTP
– Anonymous FTP allows a user to retrieve documents, files, programs, and other
archived data from anywhere in the Internet without having to establish a userid and password. By using
the special userid of "anonymous" the network user will bypass local security checks and will have access
to publicly accessible files on the remote system.
ARP (Address Resolution Protocol)
– An IETF standard that allows an IP node to determine the
hardware (datalink) address of a neighboring node. ARP provides a method of converting Protocol
Addresses (e.g., IP addresses) to Local Network Addresses (e.g., Ethernet addresses). ARP exists as a
low-level protocol within the TCP/IP suite and is used to "map" IP addresses to Ethernet (or other)
addresses (i.e., ARP provides the physical address when only the logical address is known).
Attack
– An attempt at breaking part or all of a cryptosystem; can be either a successful or unsuccessful
attempt. Many types of attacks can occur (e.g., algebraic attack, birthday attack, brute force attack,
chosen ciphertext attack, chosen plaintext attack, known plaintext attack, linear cryptanalysis,
middleperson attack).
