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.​ A NIDS Manager manages the NIDS
sensors that detect the devices and builds "detects::detected by" relationships between the NIDS records (parent) and the CIs it discovers (child).​

This topic lists the relevant classes that the CMDB CI Class Models app adds or updates. See the class columns table for further details about the columns added for each class.

CMDB CI Class Models is a ServiceNow Store app that adds class models that extend the CMDB class hierarchy. The new or updated classes include class descriptions, identification rules, identifier entries, and, if applicable, dependent relationships. You can use the added classes just like any other CMDB class. Applications such as Discovery and Service Mapping Patterns can use the class extensions to populate CIs and discover technologies and software.

See the [full release notes for all CMDB CI Class Models](https://www.servicenow.com/docs/bundle/store-release-notes/page/release-notes/store/it-operations-management/store-rn-itom-cmdb-class-models.html?emcs_t=S2h8ZW1haWx8Ym9hcmRfc3Vic2NyaXB0aW9ufE1FMlVTSFREVDc3S0hTfDMzNDcxMjV8U1VCU0NSSVBUSU9OU3xoSw).

This section lists the classes that the CMDB CI Class Models app adds or updates.See the class columns table for further details about the columns added for each class.  
CMDB CI Class Models: Release 1.30 adds the following classes for the Network Intrusion Detection System (NIDS). For the list of classes in the base system, including classes that this app might extend, see [CMDB tables descriptions](https://servicenow-prod.fluidtopics.net/4cOwgEVj_nQ7LgaXZkKfwQ "List of tables in the CMDB in a base system with its name, label, and a description of the type of information that is stored in the table.").{#cmdb-network-ids-nids-ci-extension-class__table_olh_1xp_t4b__entry__3}

| Class | Extends | Description |
|-|-|-|
| Network Intrusion Detection System (NIDS) (cmdb_ci_nids) | cmdb_ci_ids_network | NIDS is an intrusion detection system within the network that examines the traffic from all devices on the network. NIDS scanners build relationships between the OT network scanning appliances, and the OT devices on the network.​ An NIDS Manager manages the NIDS sensors.​ |

## Class columns {#cmdb-network-ids-nids-ci-extension-class__section_nwl_mvv_nkb}

CMDB CI Class Models: Release 1.30 adds the following columns to the Network Intrusion Detection System (NIDS) \[cmdb_ci_nids\] class.
{#cmdb-network-ids-nids-ci-extension-class__table_itb_kft_5qb__entry__3}

| Column label | Column name | Description |
|-|-|-|
| NIDS source ID | Correlation_id | Identifier of the NIDS device. Uses the assigned Correlation ID for the NIDS as its nids_source_id. |
| NIDS source name | nids_source_name | Name of the NIDS device. |
| Network type assignment | network_type_assignment | Designates if the device is on an IT or OT network. |
| NIDS assignment site | isa_entity_site | ISA site assigned to the NIDS. This information is available when the logged in user has an assigned ISA Admin role. |

## Roles and Access Control Logic (ACLs) {#cmdb-network-ids-nids-ci-extension-class__section_agt_nt2_s4b}

The NIDS Admin (cmdb_nids_admin) role is associated with the Network Intrusion
Detection System (NIDS) \[cmdb_ci_nids\] class: Can create, read, update, and delete Network IDS
(NDIS) OT records. To view the Network IDS Application selection on the application menu, you
must have this role.

## Key relationship structure {#cmdb-network-ids-nids-ci-extension-class__section_edm_155_yjb}

For each CMDB CI record with a "Detected by" relationship with an NIDS record, a ServiceNow
Operational Technology Certified Service Graph Connector does the
following:

1. Assigns the following NIDS-related metadata values to the CI:
   1. Location
   2. Company
   3. Related users (Owned by, Managed by, Supported by, Assigned to)
   4. Related user groups (Approval group, Managed by Group, Support group, Change group)
   {#cmdb-network-ids-nids-ci-extension-class__ol_ykb_nf3_crb}
2. If the NIDS network type is set to OT, it assigns the following NIDS-related metadata values to the CI:
   1. Creates an OT device (cmdb_ot_entity) record for the CI, using the cmdb_ot_entity reference on the CI.
   2. Assigns the NIDS assignment zone to the OT device record.
   3. If the Industrial Process Manager is installed, assign the NIDS assignment site to the OT device record.
   {#cmdb-network-ids-nids-ci-extension-class__ol_zkb_nf3_crb}
3. <var class="keyword varname">Life Cycle Stage</var> and <var class="keyword varname">Life Cycle Stage Status</var> values for the CI are used to capture the learning mode of a sensor.
   * If <var class="keyword varname">Life Cycle Stage</var> is Operational and <var class="keyword varname">Life Cycle Stage Status</var> is Learning Mode, then validation is unsuccessful.
   * If <var class="keyword varname">Life Cycle Stage Status</var> is In Use, validation is successful.
