certificate

Digital representation of user or device attributes, including a public key, that is signed with an

authoritative private key.

cidDump

A script that captures a large amount of information including the IPS processes list, log files, OS

information, directory listings, package information, and configuration files.

CIDEE

Cisco Intrusion Detection Event Exchange. Specifies the extensions to SDEE that are used by Cisco

IPS systems. The CIDEE standard specifies all possible extensions that may be supported by Cisco IPS

systems.

CIDS header

The header that is attached to each packet in the IPS system. It contains packet classification, packet

length, checksum results, timestamp, and the receive interface.

cipher key

The secret binary data used to convert between clear text and cipher text. When the same cipher key is

used for both encryption and decryption, it is called symmetric. When it is used for either encryption

or decryption (but not both), it is called asymmetric.

Cisco IOS

Cisco system software that provides common functionality, scalability, and security for all products

under the CiscoFusion architecture. Cisco IOS allows centralized, integrated, and automated

installation and management of internetworks while supporting a wide variety of protocols, media,

services, and platforms.

CLI

command-line interface. A shell provided with the sensor used for configuring and controlling the

sensor applications.

CollaborationApp

A component of the IPS. Shares information with other devices through a global correlation database

to improve the combined efficacy of all the devices.

command and

control interface

The interface on the sensor that communicates with the IPS manager and other network devices. This

interface has an assigned IP address.

community

In SNMP, a logical group of managed devices and NMSs in the same administrative domain.

composite attack

Spans multiple packets in a single session. Examples include most conversation attacks such as FTP,

Telnet, and most Regex-based attacks.

connection block

ARC blocks traffic from a given source IP address to a given destination IP address and destination

port.

console

A terminal or laptop computer used to monitor and control the sensor.

console port

An RJ45 or DB9 serial port on the sensor that is used to connect to a console device.

control interface

When ARC opens a Telnet or SSH session with a network device, it uses one of the routing interfaces

of the device as the remote IP address. This is the control interface.

control transaction

CT. An IPS message containing a command addressed to a specific application instance. Control

transactions can be sent between a management application and an IPS sensor, or between applications

on the same IPS sensor. Example control transactions include start, stop, getConfig.

Control Transaction

Server

A component of the IPS. Accepts control transactions from a remote client, initiates a local control

transaction, and returns the response to the remote client.

Control Transaction

Source

A component of the IPS. Waits for control transactions directed to remote applications, forwards the

control transactions to the remote node, and returns the response to the initiator.
