# Related information

Find more information about the Network Intrusion Detection System \(NIDS\) extension class, OT extension classes, and related applications.

## Extension classes overview

The extension classes help you understand how Operational Technology Management works with the Configuration Management Database \(CMDB\).

-   **[Network Intrusion Detection System \(NIDS\) CI extension class](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/servicenow-platform/cmdb-network-ids-nids-ci-extension-class.md)**

    The Network Intrusion Detection System \(NIDS\) \[cmdb\_ci\_nids\] class builds the relationships between passive network monitoring appliances, and the devices on the network that it discovers.

-   **[Operational Technology \(OT\) extension classes](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/servicenow-platform/cmdb-ci-class-models-operation-technology.md)**

    The Configuration Management Database \(CMDB\) updates classes for OT.


## Related applications

-   **[Vulnerability Response](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/security-management/vuln-landing-page.md)**

    When integrated with Operational Technology Vulnerability Response, the ServiceNow Vulnerability Response application aids you in prioritizing and resolving OT vulnerabilities based on process criticality.

-   **[CMDB CI Class Models app](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/servicenow-platform/cmdb-ci-class-models.md)**

    The CMDB CI Class Models store app adds class models that extend the CMDB class hierarchy, including class descriptions, identification rules, identifier entries, and dependent relationships.

-   **[Industrial Process Manager](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/industrial-process-manager/industrial-process-manager-overview.md)**

    Use the Industrial Process Manager application to create the ISA-95 Equipment Model data foundation that is required for the ServiceNow Industrial solution, enabling you to create your own version of the equipment models in each of your industrial sites.

-   **[Operational Technology Manager](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-manager/operational-technology-manager.md)**

    The Operational Technology Manager application enables you to aggregate OT device data from multiple sources, so that you can build the foundational data relationships used in the Industrial solution.
