# Operational Technology dependencies

The following tables describe the application dependencies required for Operational Technology \(OT\) device management and OT vulnerability management.

## OT device management

For a full view of your OT device data and its management, you need the applications and features in the following table.

**Note:** OT licenses for Operational Technology Service Management \(OTSM\) apply to OTSM, not ITSM. For more information, see the [OT Dependencies \[KB3146763\] article](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB3146763) in the Now SupportKnowledge Base.

Creates the foundational data and relationships that enable your enterprise to use the Operational Technology Management solution.For more information, see [Operational Technology Manager](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-manager/operational-technology-manager.md).

</td></tr><tr><td>

IT Discovery for OT Networks \(sn\_otsm\_discovery\)

</td><td>

Discovers IT class OT devices. These devices are located in designated Purdue levels within your Industrial Control System \(ICS\) networks. IT class items include switches, routers, and computers that exist both in data centers and in your factories.For more information, see [IT Discovery for Operational Technology \(OT\) Networks](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/discovery-for-operational-technology.md).

</td></tr><tr><td>

OT Enhanced Access Control \(sn\_ot\_enhanced\_acl\)

</td><td>

Implements data filters, deny unless access control rules \(ACLs\), and ACL query rules to help improve system security.For more information, see [Enhanced Access Control for Operational Technology](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-manager/ot-enhanced-access-control.md).

</td></tr><tr><td>

OT Manager Foundation \(sn\_otm\_gen\_ai\)

</td><td>

Uses generative AI to help streamline processes in the Industrial Workspace related to your OT device data.For more information, see [Operational Technology \(OT\) Manager Foundation](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/now-assist-for-otm-landing.md).

</td></tr><tr><td>

OT Asset Management \(com.sn\_otam\)

</td><td>

A specialized offering within the suite of Enterprise Asset Management solutions for managing OT and Operational Equipment \(OE\) assets. With OT Asset Management, you can effectively manage the lifecycle of OT and OE assets.For more information, see [OT Asset Management](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/it-asset-management/ot-asset-management.md).

</td></tr><tr><td>

Operational Technology Change Management \(sn\_ot\_chg\_mgmt\)

</td><td>

Enables your team members to work collaboratively on changes to OT devices or industrial equipment configurations.For more information, see [Operational Technology Change Management](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-change-management/operational-technology-change-management-landing-page.md).

</td></tr><tr><td>

Recommended Actions for Operational Technology Service Management \(OTSM\) \(sn\_otsm\_ra\)

</td><td>

Enables you to set up and apply real-time actionable recommendations for speeding up the triaging process and resolving issues quickly across various records in the Industrial Workspace, including OT incidents.For more information, see [Recommended Actions for Operational Technology Service Management \(OTSM\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/recommended-actions-for-otsm/recommended-actions-for-otsm.md).

</td></tr><tr><td>

ServiceNow Otto for Operational Technology \(OT\) Service Management \(sn\_otsm\_gen\_ai\)

</td><td>

Enables teams to summarize OT incident details and generate incident resolution notes to share with other users.For more information, see [ServiceNow Otto for Operational Technology \(OT\) Service Management](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/now-assist-for-operational-technology-service-management.md).

Operational Technology Vulnerability Response \(sn\_otvr\)

</td><td>

Enables effective prioritization and remediation of OT device vulnerabilities at the site level. By using the CMDB relationships of OT devices, vulnerable devices or items can be prioritized based on the criticality of the production process they automate.For more information, see [Operational Technology Vulnerability Response](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-vulnerability-response/oper-tech-vulnerability-response-landing-page.md).

</td></tr><tr><td>

Hardware Vulnerability Assessment \(sn\_otvr\_pro\)

</td><td>

Enables you to assess the firmware vulnerabilities of the OT devices in inventory and create vulnerable items \(VIT\) against the impacted OT devices.For more information, see [Operational Technology Hardware Vulnerability Assessment](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/industrial-workspace/understanding-hwd-vuln-assessment.md).

</td></tr><tr><td>

Vulnerability Solution Management \(sn\_vul\_solution\)

</td><td>

Automates the correlation of vulnerabilities in your environment with the solutions that can remediate them. It identifies the patches, configuration updates, and controls with the highest impact for your organization, eliminating the need for manual research.For more information, see [Vulnerability Solution Management](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/security-management/vuln-solution-mgmt.md).
