Cloud Discovery uses Patterns to discover certificate data that the Amazon AWS Cloud Certificate Manager (ACM) manages. Discovering this data requires installing and updating Discovery and Service Mapping Patterns and Certificate Inventory and Management.

Request apps on the Store

Visit the ServiceNow Store website to view all the available apps and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the ServiceNow Store version history release notes.

Prerequisites

Verify the configuration of an AWS account
For more information, see Exploring Cloud Discovery
Verify the installation of the plugins
Certificate Inventory and Management (sn_disco_certmgmt) at least 3.4.0
Discovery and Service Mapping Patterns (sn_itom_pattern) at least 1.12.0
Verify that Cloud Discovery has permissions to discover AWS
Run the following commands with AWS CLI to check the permissions and policies attached to your active IAM role:
  • List Certificates

    AWS_PAGER='' aws acm list-certificates --region <region>

  • Describe Certificates

    AWS_PAGER='' awsacm describe-certificate --certificate-arnarn:aws:acm:<region>:<accout_id>:certificate/<certificate_id>

  • Get Certificates

    AWS_PAGER='' awsacm get-certificate --certificate-arnarn:aws:acm:<region>:<account_id>:certificate/<certificate_id>

  • Get tags

    AWS_PAGER='' awsresourcegroupstaggingapi get-resources --tags-per-page 100 --resource-type-filters 'acm:certificate'

Set the configuration of the system property
When the system property sn_itom_pattern.issuer_certificate_search_by_idn is set to false, Discovery uses the certificate fingerprints to find issuers and root issuers.
Verify the MID Server requirements
The MID Server must have either ALL capability or AWS capability.
Verify the configuration of Cloud Discovery schedule
For more information, see Create a discovery schedule in Cloud Discovery Workspace

Verify the REST API Permissions

Download the Cloud Discovery patterns spreadsheet so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available quarterly, so check periodically to be sure you have the latest version of the spreadsheet.

Data collected by Discovery during horizontal discovery

The Amazon AWS - Certificates Manager pattern and Amazon AWS - Collect Certificates Tags shared library support the discovery of the following table and fields.
Field Description
Unique Certificates [cmdb_ci_certificate] ​
Name

The host name/domain associated with the certificate.

For example, *.service-now.com
Fingerprint

The hash value of the certificate.

For example, d708c8583c78c176d5df1a4f01aac746294 e390a03038f280b0d8f5efbc8a0f
Fingerprint algorithm

The algorithm that's being used to hash the certificate. For example, Discovery calculates fingerprints by the SHA-256 algorithm, so the value that is populated is: SHA-256
Serial Number The serial number of the certificate. For example, 70 d8 c9 52 77 1c 2d 54 97 00 0e 21 05 84 dd 76 b5 e8 c1 73
Subject common name

The host name/domain associated with the certificate. For example, *.service-now.com
Subject distinguished name

The distinguished name of the entity that the certificate is issued to.​

The subject distinguished name consists of the following
  • Common name (CN).
  • Organization (O)- The organization that owns the domain that the certificate is issued to.
  • organizational unit (OU)- The organizational unit that owns the domain that the certificate is issued to.
Issuer common name

The common name of the certificate issuer. For example, Entrust Certification Authority.
Issuer distinguished name

The distinguished name of the certificate issuer.

The issuer distinguished name consists of the following
  • Common Name (CN)- the authority that issued the certificate. For example, Entrust Certification Authority.
  • Organization (O)- The organization that issued the certificate. For example, "Entrust", Inc.
  • Organizational Unit (OU)- The unit that has the legal rights to issue the certificate.
Renewal tracking

Indicates whether to create any priority 1 or priority 3 tasks for the expiring certificates.

Discovery sets Renewal tracking to priority3 when the system property glide.discovery.certs.enable_renewal_task_creation_for_discovered_certificates is set to true.
Valid From The certificate is valid from this date (UTC). For example, 2023-09-25 10:43:03
Valid To

The expiry date of the certificate (UTC). For example, 2024-09-24 10:43:03
Subject organization

The organization (O) that the certificate is issued to.
Subject organizational unit The organizational unit (OU) that the certificate is issued to.
Subject country The country (C) of the organization that the certificate is issued to. Populated in a two-letter country code.
Subject state The region, state (ST), or province of the organization that the certificate is issued to. Populated with two-letter code.
Subject locality The city, location (L) of the organization that the certificate is issued to.
Subject email The email address of the organization that the certificate is issued to.
Issuer A reference to the entity that signed and issued the certificate. The reference is available if the issued certificate is a part of the same payload.
Root Issuer A reference to the root certificate. The reference is available if the issued certificate is a part of the same payload.
Subject alternative name The name of the certificate domain record.

CI relationships

The Amazon AWS - Certificates Manager pattern and Amazon AWS - Collect Certificates Tags shared library support the discovery of the following relationships:
