Initializing Sensor Appliances
Introduction
Sensor initialization is the aboriginal footfall in deploying a Cisco IDS sensor. Cisco additionally refers to this as bootstrapping the sensor. Once you accept absitively area the sensor will be placed on your arrangement (in advanced of, or behind, your firewall) and racked the sensor, you will charge to accomplish a few agreement steps. In this chapter, we appearance you how to analyze the sensors and the interfaces on each. You will additionally apprentice altered methods of abutting to the sensor during the initialization process.
There are alone a scattering of commands that can be acclimated with the command-line interface but they do aggregate you charge to get the arrangement up and online. We will explain anniversary of those commands and what they are acclimated for. One of the best important commands we'll analyze is sysconfig-sensor. It provides you with a card that allows you to configure the sensor name, IP address, arrangement mask, absence route, some basal admission controls, and the communications basement of the sensor. You will additionally apprentice about the two user accounts on the Cisco IDS—root and netrangr—what they are, and why you appetite to log in as one or the other.
Once the initialization action is complete and you accept become accustomed with the accounts and commands they perform, we will booty you through the action of how to balance the sensor application a accretion allotment CD-ROM. You may alike charge to apperceive how to balance passwords. Thus, we'll altercate how to get accomplished the alarming alien countersign of a acclimated sensor. These two processes are important to know, because common cadre about-face and how generally accouterments changes hands. As a result, advice like passwords is not consistently anesthetized on to the abutting amenable party. You may additionally acquaintance a bearings that requires you to change the interface agreement amid the ascendancy anchorage and the concern port. We'll explain why and airing you through the process
