58 © 2004, Cisco Systems, Inc. All rights reserved. CSIDS IDS MC Updates The IDS MC must operate with the same software and signature version as the Sensors it manages. When you update the Sensor, you must also update the IDS MC. A compressed (.zip) update file must be used to upgrade the IDS MC. To update the IDS MC, the update file must reside on the IDS MC server at X:\Program Files\CSCOpx\MDC\etc\ids\updates.

66 © 2004, Cisco Systems, Inc. All rights reserved. CSIDS Summary

67 © 2004, Cisco Systems, Inc. All rights reserved. CSIDS Summary The IDS MC provides a web-based interface for configuring and managing multiple IDS Sensors. The IDS MC can be installed on Windows-based and Solaris-based servers. The IDS MC allows the grouping of Sensors into Sensor groups for ease of management and configuration.

68 © 2004, Cisco Systems, Inc. All rights reserved. CSIDS Summary (Cont.) For the IDS MC to understand the software installed on the Sensor, it must operate with the same software and signature version as the Sensors it manages. Therefore, if you apply a service pack or signature update to a Sensor managed by the IDS MC, you must also update the IDS MC. The IDS MC provides a mechanism for controlling the approval and deployment of Sensor configuration files. The IDS MCs reporting capability provides a method for determining the status of configuration deployment.
