Numerics
See DES.
3DES
A
Authentication, authorization, and accounting. See also
AAA
Area Border Router. In OSPF, a router with interfaces in multiple areas.
ABR
access control entry. Information entered into the configuration that lets you specify what type of traffic
ACE
to permit or deny on an interface. By default, traffic that is not explicitly permitted is denied.
The adaptive security appliance CLI uses several command modes. The commands available in each
Access Modes
mode vary. See also
command-specific configuration
access control list. A collection of ACEs. An ACL lets you specify what type of traffic to allow on an
ACL
interface. By default, traffic that is not explicitly permitted is denied. ACLs are usually applied to the
interface
A set of object-oriented programming technologies and tools used to create mobile or portable
ActiveX
programs. An ActiveX program is roughly equivalent to a Java applet.
See ARP.
Address Resolution
Protocol
The translation of a network address and/or port to another network address/or port. See also
address translation
interface
Advanced Encryption Standard. A symmetric block cipher that can encrypt and decrypt information.
AES
The AES algorithm is capable of using cryptographic keys of 128, 192 and 256 bits to encrypt and
decrypt data in blocks of 128 bits. See also DES.
Authentication Header. An IP protocol (type 51) that can ensure data integrity, authentication, and
AH
replay detection. AH is embedded in the data to be protected (a full IP datagram, for example). AH can
be used either by itself or with ESP. AH is an older
networks than ESP. AH provides authentication services but does not provide encryption services. It is
provided to ensure compatibility with
authentication
Advanced Inspection and Prevention. For example, the AIP SSM or AIP SSC, which runs IPS software.
