AWS IAM Policy pattern-based discovery

Discovery and Service Mapping Patterns finds AWS IAM Policies 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 AWS discovery prerequisites

For more information, see the prerequisites section in AWS discovery using patterns.

Remove resources from the Resource Inclusion List table

Verify that the relevant resource isn't listed in the Resource Inclusion List [sa_cloud_inventory_resource_whitelist] table to avoid duplicate discovery. For more information on removing resources from the Resource Inclusion List, see AWS Resource Inventory discovery with 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.

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 Amazon AWS - IAM Policy - Extended Inventory (LP) pattern.

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

Table 1. AWS IAM Policy [cmdb_aws_iam_policy]

Name [name]	Name of the IAM policy.
Object ID [object_id]	The Amazon Resource Name (ARN) of the IAM policy.
Policy ID [policy_id]	The stable and unique string identifying the policy.
Is Customer Managed [is_customer_managed]	Indicates whether the policy is customer-managed. Policies managed by customers: the value is true Policies managed by AWS: the value is false
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 Amazon AWS - IAM Policy - Extended Inventory (LP) pattern.

Table 2. Cloud Resource [cmdb_ci_cmp_resource]

Field	Description
Name [name]	Name of the IAM policy.
Object ID [object_id]	The ARN of the IAM policy.
Resource type [resource_type]	Type of resource. The value is set to AWS::IAM::Policy.

CI relationships

The Amazon AWS - IAM Policy - Extended Inventory (LP) pattern creates the following relationships and references to support AWS IAM Policy discovery. References link to records in other tables and don't appear in the CI Relationship [cmdb_rel_ci] table.

Table 3. CI relationships

CI	Relationship	CI
Cloud Resource [cmdb_ci_cmp_resource]	Hosted on::Hosts	Cloud Service Account [cmdb_ci_cloud_service_account]

Table 4. CI references

CI	Field	Referenced CI
AWS IAM Policy [cmdb_aws_iam_policy]	Configuration Item [configuration_item]	Cloud Resource [cmdb_ci_cmp_resource]
Key Value [cmdb_key_value]	Configuration item [configuration_item]	Cloud Resource [cmdb_ci_cmp_resource]

AWS Tag discovery

The Amazon AWS - IAM Policy - Extended Inventory (LP) pattern collects tags and populates them in the Key Value [cmdb_key_value] table.

Table 5. Key Value [cmdb_key_value]

Field	Description
Key [key]	Tag name.
Value [value]	Tag value.
Configuration item [configuration_item]	References the Cloud Resource [cmdb_ci_cmp_resource] table.
