Glossary
"A" stands for address, and refers to name-to-address mapped records in DNS.
A record address
Address Resolution Protocol. A low-level TCP/IP protocol that maps a hardware address, or MAC
ARP
address, to an IP address. An example hardware address is 00:00:a6:00:01:ba. The first three groups
of characters (00:00:a6) identify the manufacturer; the rest of the characters (00:01:ba) identify the
system card. ARP is defined in RFC 826.
Adaptive Security Algorithm. Used by the FWSM to perform inspections. ASA allows one-way
ASA
(inside to outside) connections without an explicit configuration for each internal system and
application. See also
adaptive security appliance.
ASA
Adaptive Security Device Manager. An application for managing and configuring a single FWSM.
ASDM
Also called public key systems, asymmetric encryption allows anyone to obtain access to the public
asymmetric
key of anyone else. Once the public key is accessed, one can send an encrypted message to that person
encryption
using the public key. See also encryption,
Cryptographic protocols and services that verify the identity of users and the integrity of data. One of
authentication
the functions of the
ensures that it is not tampered with in transit. It also provides confirmation about the origin of the
datastream. See also AAA, encryption, and VPN.
B
Border Gateway Protocol. BGP performs interdomain routing in TCP/IP networks. BGP is an Exterior
BGP
Gateway Protocol, which means that it performs routing between multiple autonomous systems or
domains and exchanges routing and access information with other BGP systems. The FWSM does not
support BGP. See also EGP.
Bandwidth Limited Traffic stream. Stream or flow of packets whose bandwidth is constrained.
BLT stream
Bootstrap Protocol. Lets diskless workstations boot over the network as is described in RFC 951 and
BOOTP
RFC 1542.
Bridge Protocol Data Unit. Spanning-Tree Protocol hello packet that is sent out at configurable
BPDU
intervals to exchange information among bridges in the network. Protocol data unit is the OSI term
for packet.
C
Certificate Authority, Certification Authority. A third-party entity that is responsible for issuing and
CA
revoking certificates. Each device with the public key of the CA can authenticate a device that has a
certificate issued by the CA. The term CA also refers to software that provides CA services. See also
certificate, CRL,
A temporary repository of information accumulated from previous task executions that can be reused,
