Discovery and Service Mapping Patterns finds AWS Network access control lists (ACLs) 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 {#aws-acl-pattern__section_rpj_fj2_bgc}

Verify the AWS discovery prerequisites
:   For more information, see the prerequisites section in [Amazon AWS Cloud components discovery using patterns](https://servicenow-prod.fluidtopics.net/nnBwzYmMo_kpTZpG3y5~xQ "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

Configure the Discovery schedule to support GovCloud
:   Discovering AWS GovCloud (US) accounts requires using a datacenter URL when setting up an AWS service account. For more information, see [Create AWS service accounts](https://servicenow-prod.fluidtopics.net/CvTA68TY3ph_FRR49RbdPg "Create AWS service accounts on the ServiceNow AI Platform to access your AWS account during AWS discovery.").

## Data collected by Discovery during horizontal discovery {#aws-acl-pattern__section_ggp_ql2_bgc}

Discovery populates the data in the CMDB when running the Amazon AWS - ACL (LP) pattern.  
{#aws-acl-pattern__table_network_acl__entry__2}

| Field | Description |
|-|-|
| Name \[name\] | Name of the network ACL. |
| Object ID \[object_id\] | Unique identifier, allocated by AWS for this resource. |
[Table 1. Network ACL \[cmdb_ci_network_acl\]]

{#aws-acl-pattern__table_network_acl}  
{#aws-acl-pattern__table_endpoint_acl__entry__2}

| Field | Description |
|-|-|
| Name \[name\] | Name of the endpoint. |
| Object ID \[object_id\] | Unique identifier, allocated by AWS for this resource. |
[Table 2. ACL Endpoint \[cmdb_ci_endpoint_acl\]]

{#aws-acl-pattern__table_endpoint_acl}

## CI relationships {#aws-acl-pattern__section_dc4_ghc_dgc}

The Amazon AWS - ACL (LP) pattern creates the following relationships and references to support AWS Network ACL discovery. References link to records in other tables and don't appear in the CI Relationship \[cmdb_rel_ci\] table.  
{#aws-acl-pattern__table_relationships__entry__3}

| CI | Relationship | CI |
|-|-|-|
| Network ACL \[cmdb_ci_network_acl\] | Hosted on::Hosts | AWS Datacenter \[cmdb_ci_aws_datacenter\] |
| Cloud Network \[cmdb_ci_network\] | Contains::Contained by | Network ACL \[cmdb_ci_network_acl\] |
| Network ACL \[cmdb_ci_network_acl\] | Implement End Point To::Implement End Point From | ACL Endpoint \[cmdb_ci_endpoint_acl\] |
| Cloud Subnet \[cmdb_ci_cloud_subnet\] | Use End Point To::Use End Point From | ACL Endpoint \[cmdb_ci_endpoint_acl\] |
