Date Added: 08/29/14
Definition: See DES.

Term: A record address
ID: 33797
Category: Cisco Systems
Date Added: 08/29/14
Definition: "A" stands for address, and refers to name-to-address mapped records in DNS.

Term: AAA
ID: 33798
Category: Cisco Systems
Date Added: 08/29/14
Definition: Authentication, authorization, and accounting. See also TACACS+ and RADIUS.

Term: ABR
ID: 33799
Category: Cisco Systems
Date Added: 08/29/14
Definition: Area Border Router. In OSPF, a router with interfaces in multiple areas.

Term: Access Modes
ID: 33800
Category: Cisco Systems
Date Added: 08/29/14
Definition: The security appliance CLI uses several command modes. The commands available in each mode vary. See also user EXEC mode, privileged EXEC mode, global configuration mode, command-specific configuration mode.

Term: ACE
ID: 33801
Category: Cisco Systems
Date Added: 08/29/14
Definition: Access Control Entry. Information entered into the configuration that lets you specify what type of traffic to permit or deny on an interface. By default, traffic that is not explicitly permitted is denied.

Term: ACL
ID: 33802
Category: Cisco Systems
Date Added: 08/29/14
Definition: Access Control List. A collection of ACEs. An ACL lets you specify what type of traffic to allow on an interface. By default, traffic that is not explicitly permitted is denied. ACLs are usually applied to the interface which is the source of inbound traffic. See also rule, outbound ACL.

Term: ActiveX
ID: 33803
Category: Cisco Systems
Date Added: 08/29/14
Definition: A set of object-oriented programming technologies and tools used to create mobile or portable programs. An ActiveX program is roughly equivalent to a Java applet.

Term: Address Resolution Protocol
ID: 33804
Category: Cisco Systems
Date Added: 08/29/14
Definition: See ARP.

Term: address translation
ID: 33805
Category: Cisco Systems
Date Added: 08/29/14
Definition: The translation of a network address and/or port to another network address/or port. See also IP address, interface PAT, NAT, PAT, Static PAT, xlate.

Term: AES
ID: 33806
Category: Cisco Systems
Date Added: 08/29/14
Definition: Advanced Encryption Standard. A symmetric block cipher that can encrypt and decrypt information. 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.

Term: AH
ID: 33807
Category: Cisco Systems
Date Added: 08/29/14
Definition: Authentication Header. An IP protocol (type 51) that can ensure data integrity, authentication, and 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. This is an older IPSec protocol that is less important in most networks than ESP. AH provides authentication services but does not provide encryption services. It is provided to ensure compatibility with IPSec peers that do not support ESP, which provides both authentication and encryption. See also encryption andVPN. Refer to the RFC 2402.

Term: APCF
ID: 33808
Category: Cisco Systems
Date Added: 08/29/14
Definition: Application Profile Customization Framework. Lets the security appliance handle non-standard applications so that they render correctly over a WebVPN connection.

Term: ARP
ID: 33809
Category: Cisco Systems
Date Added: 08/29/14
Definition: Address Resolution Protocol. A low-level TCP/IP protocol that maps a hardware address, or MAC 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.

Term: ASA
ID: 33810
Category: Cisco Systems
Date Added: 08/29/14
Definition: Adaptive Security Algorithm. Used by the security appliance to perform inspections. ASA allows one-way (inside to outside) connections without an explicit configuration for each internal system and application. See also inspection engine.

Term: ASA
ID: 33811
Category: Cisco Systems
Date Added: 08/29/14
Definition: adaptive security appliance.

Term: ASDM
ID: 33812
Category: Cisco Systems
Date Added: 08/29/14
Definition: Adaptive Security Device Manager. An application for managing and configuring a single security appliance.

Term: asymmetric encryption
ID: 33813
Category: Cisco Systems
Date Added: 08/29/14
Definition: Also called public key systems, asymmetric encryption allows anyone to obtain access to the public key of anyone else. Once the public key is accessed, one can send an encrypted message to that person using the public key. See also encryption, public key.

Term: authentication
ID: 33814
Category: Cisco Systems
Date Added: 08/29/14
Definition: Cryptographic protocols and services that verify the identity of users and the integrity of data. One of the functions of the IPSec framework. Authentication establishes the integrity of datastream and 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.

Term: Auto Applet Download
ID: 33815
Category: Cisco Systems
Date Added: 08/29/14
Definition: Automatically downloads the WebVPN port-forwarding applet when the user first logs in to WebVPN.

Term: auto-signon
ID: 33816
Category: Cisco Systems
Date Added: 08/29/14
Definition: This command provides a single sign-on method for WebVPN users. It passes the WebVPN login credentials (username and password) to internal servers for authentication using NTLM authentication, basic authentication, or both.

Term: Backup Server
ID: 33817
Category: Cisco Systems
Date Added: 08/29/14
Definition: IPSec backup servers let a VPN client connect to the central site when the primary security appliance is unavailable.

Term: BGP
ID: 33818
Category: Cisco Systems
Date Added: 08/29/14
Definition: Border Gateway Protocol. BGP performs interdomain routing in TCP/IP networks. BGP is an Exterior 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 security appliance does not support BGP. See also EGP.

Term: BLT stream
ID: 33819
Category: Cisco Systems
Date Added: 08/29/14
Definition: Bandwidth Limited Traffic stream. Stream or flow of packets whose bandwidth is constrained.

Term: BOOTP
ID: 33820
Category: Cisco Systems
Date Added: 08/29/14
Definition: Bootstrap Protocol. Lets diskless workstations boot over the network as is described in RFC 951 and RFC 1542.
