    Summary of Operational Technology dependencies

    This guide outlines the essential ServiceNow applications and features required for comprehensive management of Operational Technology (OT) devices and vulnerabilities. It covers dependencies for two main areas: OT device management and OT vulnerability management. Understanding and implementing these dependencies ensures effective OT asset lifecycle management, security, and incident resolution within your industrial environment.

    OT device management

    To achieve a full view and management capabilities of OT device data, the following applications are required:

    • Operational Technology Manager (snotfoundation): Establishes foundational data and relationships for OT management solutions.
    • IT Discovery for OT Networks (snotsmdiscovery): Discovers IT-class OT devices such as switches, routers, and computers within ICS networks.
    • OT Enhanced Access Control (snotenhancedacl): Applies security through data filters and access control rules to protect OT data.
    • OT Manager Foundation (snotmgenai): Leverages generative AI to streamline OT device data processes in the Industrial Workspace.
    • OT Asset Management (com.snotam): Manages the lifecycle of OT and Operational Equipment (OE) assets within Enterprise Asset Management.
    • Operational Technology Change Management (snotchgmgmt): Facilitates collaboration on OT device and equipment configuration changes.
    • Recommended Actions for OTSM (snotsmra): Provides real-time actionable recommendations to accelerate issue triaging and resolution in OT incidents.
    • ServiceNow Otto for OT Service Management (snotsmgenai): Uses AI to summarize OT incident details and generate resolution notes for team communication.

    Note: OT licenses apply specifically to Operational Technology Service Management (OTSM), not to IT Service Management (ITSM).

    OT vulnerability management

    For comprehensive OT vulnerability tracking and remediation, these applications are essential:

    • Operational Technology Vulnerability Response (snotvr): Prioritizes and remediates OT device vulnerabilities using CMDB relationships and production criticality.
    • Hardware Vulnerability Assessment (snotvrpro): Assesses firmware vulnerabilities in OT devices and creates Vulnerable Items (VITs) for impacted devices.
    • Vulnerability Solution Management (snvulsolution): Automates correlation between vulnerabilities and remediation solutions like patches and configuration updates.
    • Operational Technology Manager (snotfoundation): Provides foundational data structures for OT vulnerability management.
    • OT Enhanced Access Control (snotenhancedacl): Enhances security through access control rules for vulnerability data.
    • OT Manager Foundation (snotmgenai): Employs generative AI to optimize OT vulnerability processes in the Industrial Workspace.

    Practical impact for ServiceNow customers

    By deploying these applications and features, your organization can:

    • Gain an integrated and accurate view of OT assets and their lifecycle status.
    • Improve security posture through enhanced access control and vulnerability prioritization.
    • Accelerate incident triage and resolution using AI-driven recommendations and automation.
    • Collaborate effectively on OT device changes to minimize operational risks.
    • Streamline vulnerability assessments and remediation efforts at the site level, aligned with production criticality.

    Implementing these dependencies is crucial to managing OT environments efficiently, securing critical infrastructure, and ensuring operational continuity within industrial settings.

    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.
    Application/Feature Description
    Operational Technology Manager (sn_ot_foundation) Creates the foundational data and relationships that enable your enterprise to use the Operational Technology Management solution.

    For more information, see Operational Technology Manager.
    IT Discovery for OT Networks (sn_otsm_discovery) 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.
    OT Enhanced Access Control (sn_ot_enhanced_acl) 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.
    OT Manager Foundation (sn_otm_gen_ai) 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.
    OT Asset Management (com.sn_otam) 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.
    Operational Technology Change Management (sn_ot_chg_mgmt) Enables your team members to work collaboratively on changes to OT devices or industrial equipment configurations.

    For more information, see Operational Technology Change Management.
    Recommended Actions for Operational Technology Service Management (OTSM) (sn_otsm_ra) 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).
    ServiceNow Otto for Operational Technology (OT) Service Management (sn_otsm_gen_ai) 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.

    OT vulnerability management

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

    Application/Feature Description
    Operational Technology Vulnerability Response (sn_otvr) 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.
    Hardware Vulnerability Assessment (sn_otvr_pro) Enables you to assess the firmware vulnerabilities of the OT devices in inventory and create vulnerable items (VIT) against the impacted OT devices.
