This process helps maintain CMDB integrity by identifying and removing stale or obsolete CIs associated with infrastructure or applications that no longer exist. Show full answer Show less Using the CMDB Data Manager within CMDB Workspace, you can create attestation policies that define which CIs require verification and how frequently this should occur. Attestation tasks are assigned to knowledgeable users who can validate or reject the CIs. Rejected CIs can then be retired, archived, or deleted, keeping your CMDB clean and accurate. ## Key Features * **Attestation Policies:** Define which CIs to attest and set the frequency for attestation tasks. * **Task Assignment and Management:** Assign attestation tasks to users familiar with the CIs; users manage these tasks through the Tasks view in CMDB Workspace. * **Smart Detection and Auto-Attestation:** Automatically identify and attest CIs based on recent discovery results, streamlining the attestation process. ## Smart Detection Details Smart detection allows you to auto-attest CIs discovered within a configurable time window, provided discovery is enabled or Service Graph Connectors are implemented. It uses specific system properties to filter candidate CIs: * **Discovery Window:** Specifies the number of days (default 30) in which a CI must have been discovered to qualify for auto-attestation. * **Discovery Source Exclusion:** Excludes CIs discovered by unreliable sources from auto-attestation candidates. * **Smart Detection Enablement:** Controlled by a system property that enables or disables smart detection (default is enabled). ## Key Outcomes * Improved CMDB accuracy by validating that CIs represent actual, existing IT infrastructure and applications. * Systematic removal of stale or obsolete CIs, reducing clutter and ensuring reliable configuration data. * Reduced manual effort through smart detection and auto-attestation capabilities, accelerating the attestation workflow. * Better assignment and tracking of attestation tasks via CMDB Workspace, empowering users to efficiently maintain CMDB integrity. Verify the existence of actual IT infrastructure and applications that you own, systematically and in bulk. As CIs are continuously ingested into the CMDB from various data sources, ensure the integrity of the CMDB. Remove any stale CIs that are associated with IT infrastructure or applications that no longer exists. Use the [CMDB Data Manager in CMDB Workspace](https://www.servicenow.com/docs/UtriErXMjwcjBC5hlJBMug "Use the CMDB Data Manager in CMDB Workspace to administer policies, CIs life-cycle and attestation tasks, view analytics about on-going CMDB Data Manager processes, and to approve or reject assigned tasks.") to [create an Attestation policy](https://www.servicenow.com/docs/Vh0a7mlqb5tcuH~QZasq9Q "Create a CMDB Data Manager policy in CMDB Workspace to automatically process CIs life-cycle events such as deletion. Applying consistent and standard life-cycle policies to CIs helps maintain the health of the CMDB."), specifying CIs that need to be attested and the attestation frequency. Assign Attestation tasks to users that are familiar with or that manage the CIs, and who can attest or reject the IT infrastructure or applications that those CIs represent. Rejected CIs that are no longer needed can then be retired, archived, or deleted from the CMDB. Users can go to the [Tasks view in CMDB Workspace](https://www.servicenow.com/docs/DCVeOSfwJh5SHzRbeCzDdg "The Task view in CMDB Workspace provides task owners access for tracking and managing their tasks such as CMDB Health related tasks, certification, attestation, and lifecycle tasks generated by the CMDB Data Manager.") to see their assigned attestation tasks, and then [review and process the tasks](https://www.servicenow.com/docs/R7ipu_K3kYX8iGfsfehFJA "Review attestation tasks that are assigned to you or to an assignment group that you belong to in accordance with CMDB Data Manager Attestation policies. Check the physical existence of IT infrastructure or applications associated with CIs in the attestation task and then process those CIs as appropriate."). ## Smart detection and auto-attestation {#attesting-cis__section_ci_attestation_smart_detection} Smart detection streamlines and simplifies CI attestation. With smart detection you can auto-attest CIs that are automatically detected by discovery programs, based only on recent discovery results. The following conditions must be met to enable smart detection: * [Discovery](https://www.servicenow.com/docs/access?context=r-discovery&version=brazil&pubname=brazil-it-operations-management&ft:locale=en-US) is enabled in your organization or [Getting started with Service Graph Connectors](https://www.servicenow.com/docs/mRCOEjfrvYv2Aq05aVS7WA "Service Graph Connectors, including API Service Graph Connectors, are predefined integrations that ingest third-party data and API data into the Configuration Management Database (CMDB) from various domains, such as security, servers, software or monitoring, Internet of Things (IoT), and cloud.") are implemented. * The system property sn_cmdb_ws.attestation.smart_detection.disabled is set to false (default value). {#attesting-cis__ul_x3x_gqs_gtb} In addition, smart detection uses the following system properties as filters when creating a list of CIs that are candidates for auto-attestation. To be included as candidates for auto-attestation, CIs must be discovered: * Within the discovery time window specified by the sn_cmdb_ws.attestation.smart_detection.discovery_window system property (for example, within the last 30 days) * By any discovery source that isn't excluded by the sn_cmdb_ws.attestation.smart_detection.discovery_source.exclusion system property {#attesting-cis__ul_ccv_l4p_dtb}Then, when you [review those candidate CIs](https://www.servicenow.com/docs/R7ipu_K3kYX8iGfsfehFJA "Review attestation tasks that are assigned to you or to an assignment group that you belong to in accordance with CMDB Data Manager Attestation policies. Check the physical existence of IT infrastructure or applications associated with CIs in the attestation task and then process those CIs as appropriate."), you can choose to auto-attest them. ## Properties associated with Attestation {#attesting-cis__section_qmp_s3s_wsb} {#attesting-cis__table_cny_5y4_ts__entry__2} | Property | Description | |-|-| | sn_cmdb_ws.attestation.smart_detection.disabled | Disables smart detection. * Type: true \| false * Default value: false * Values: * true: Disable smart detection. * false: Enable smart detection. {#attesting-cis__ul_jjr_ky4_bnb} * Location: [Add to System Properties \[sys_properties\]](https://www.servicenow.com/docs/access?context=t_AddAPropertyUsingSysPropsList&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US) table. * Learn more: [Review attestation tasks in CMDB Workspace](https://www.servicenow.com/docs/R7ipu_K3kYX8iGfsfehFJA "Review attestation tasks that are assigned to you or to an assignment group that you belong to in accordance with CMDB Data Manager Attestation policies.
