    Summary of Azure Disk Encryption Set pattern-based discovery

    The Azure Disk Encryption Set pattern-based discovery enables ServiceNow customers to identify and map Azure Disk Encryption Set resources within their cloud environment using the Discovery and Service Mapping Patterns application. This discovery populates detailed information into both CMDB and non-CMDB tables, supporting comprehensive visibility and management of Azure encryption resources.

    Key Features

    • Pattern Activation: The Azure Disk Encryption Set pattern is disabled by default. From Visibility Content version 6.28.0 onward, enabling or disabling this pattern does not count as a customization, allowing it to receive automatic updates while preserving activation status after upgrades.
    • Discovery Prerequisites: Customers must meet Microsoft Azure discovery prerequisites and configure Azure service accounts correctly, especially when discovering Azure GovCloud (US) accounts, which require a datacenter URL.
    • Data Population: Discovery results are stored in both CMDB and non-CMDB tables:
      • Non-CMDB: The cmdbazurediskencryptionsetdiskencryptionset table stores specific encryption set details such as encryption type, identity type, key URL, location, provisioning state, and tenant information.
      • CMDB: The cmdbcicmpresource table captures core cloud resource data including install status, operational status, object ID, and resource type (set as microsoft.compute/diskencryptionsets).
    • CI Relationships: The pattern establishes relationships among resources to accurately represent structure and dependencies. For example, encryption sets are linked to resource groups and Azure datacenters.
    • Tag Collection: The discovery collects Azure tags and stores them in the cmdbkeyvalue table, maintaining tag name and value pairs for enhanced resource metadata management.

    Practical Benefits for ServiceNow Customers

    • Gain precise visibility into Azure Disk Encryption Sets within the CMDB, supporting security and compliance efforts.
    • Automate the discovery and ongoing updates of encryption-related cloud resources, reducing manual tracking.
    • Leverage comprehensive CI relationships to understand resource dependencies, improving impact analysis and change management.
    • Support Azure GovCloud (US) discovery requirements, ensuring coverage of specialized cloud environments.
    • Maintain up-to-date encryption resource metadata, including tags, enhancing reporting and governance.

    Discovery and Service Mapping Patterns finds Azure services on your cloud environment. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Pattern-based discovery and mapping requirements

    Verify the Microsoft Azure discovery prerequisites
    For more information, see the prerequisites section in Microsoft Azure Cloud discovery using patterns.
    Enable the relevant pattern
    The pattern for this service is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating a pattern won't be considered a customization, and it will continue to receive updates. Patterns that were previously activated or deactivated will reset to the latest predefined version after upgrading while retaining the last active field value. For more information on enabling patterns, see Activate a disabled pattern.
    Configure the Discovery schedule to support GovCloud
    Discovering Azure GovCloud (US) accounts requires using a datacenter URL when setting up an Azure service account. For more information, see Set up Azure service accounts.

    Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

    Data stored in non-CMDB tables

    Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Azure - Disk Encryption Set - Extended Inventory(LP) pattern.

    You can review the non-CMDB Azure tables by navigating to All > Configuration > Azure. You can also search the navigation filter for the specific pattern name.

    Table 1. Azure Disk Encryption Set [cmdb_azure_disk_encryption_set_disk_encryption_set]
    Field Description
    Encryption Type [encryption_type] The method used to encrypt the resource data.
    Identity type [identity_type] The classification of the identity assigned to the resource. For example: SystemAssigned or UserAssigned.
    Key Url [key_url] The URL where the encryption key is stored or accessible.
    Location [location] The geographic region where the resource is deployed.
    Object Id [object_id] The unique identifier of the resource.
    Provisioning State [provisioning_state] The current status of the resource provisioning process.
    Resource Group [resource_group] Name of the resource group.
    Tenant Id [tenant_id] The identifier for the tenant that owns the resource.
    Configuration Item [configuration_item] References the Cloud Resource [cmdb_ci_cmp_resource] table.

    Data stored in CMDB tables

    Discovery and Service Mapping Patterns application populates data in the CMDB when running the Azure - Disk Encryption Set - Extended Inventory(LP) pattern.

    Table 2. Cloud Resource [cmdb_ci_cmp_resource]
    Field Description
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Location [location] The geographic region where the resource is deployed.
    Name [name] The name of the resource.
    Object ID [object_id] The unique identifier of the resource.
    Operational status [operational_status] Operational status of the resource. Default value is Operational.
    Resource type [resource_type] Type of resource. The value is set to microsoft.compute/diskencryptionsets.

    CI relationships

    The pattern creates these relationships to support discovery.

    CI Relationship CI
    Resource Group [cmdb_ci_resource_group] Contains::Contained by Cloud Resource [cmdb_ci_cmp_resource]
    Cloud Resource [cmdb_ci_cmp_resource] Hosted on::Hosts Azure Datacenter [cmdb_ci_azure_datacenter]
    Azure Disk Encryption Set [cmdb_azure_disk_encryption_set_disk_encryption_set] References Cloud Resource [cmdb_ci_cmp_resource]

    Azure tag discovery

    The pattern collects tags and populates them in the Key Value [cmdb_key_value] table.
    Table 3. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag name.
    Value [value] Tag value.
