cidcli (CLI)—The interface that is run when you successfully log in to the
•
sensor through Telnet or SSH. All accounts created through the CLI will use
the CLI as their shell (except the service account—only one service account
is allowed). Allowed CLI commands depend on what the privilege of the user
is.
EventStore—An indexed store used to store IDS events (error, status, and
•
alert system messages) that is accessible through the CLI, IDM, or RDEP.
See
Show Version Command Output, page
the show version command, which lists the sensor applications and shows their
status.
All IDS applications communicate with each other through a common API
(IDAPI). Remote applications (other sensors, management applications, and
third-party software) communicate with sensors through the RDEP and Intrusion
Detection Interchange and Operations Messages (IDIOM) protocols.
The sensor has the following partitions:
Application partition—A full IDS system image.
•
•
Maintenance partition—A special purpose IDS image used to reimage the
application partition of the IDSM-2. All configuration is lost.
Recovery partition—A special purpose image used for recovery of the
•
appliance. Booting into the recovery partition enables you to completely
reimage the application partition. Network settings are preserved, but all
other configuration is lost.
IDSM-2 and NM-CIDS do not have recovery partitions.
Note
The following is a sample output from the show version command. All the
sensor's applications are displayed with their current status.
