Azure Container Registry

To scan a repository in Azure Container Registry (ACR), create a new registry scan setting.

Configure an ACR Registry Scan

Prerequisites:

• You have installed a Defender somewhere in your environment.
• The Defender can establish a connection with the ACR over port 443. Ensure that the port is open for the image to be accessed successfully.
• The Azure Service Principle is assigned the Contributor role. Azure Credentials for details.

1. Log in to Console, and select Defend > Vulnerabilities > Images > Registry settings.
2. Add registry.
3. In Add New Registry, enter the following values:

   1. In Version, select Azure Container Registry.
   2. Under Registry, enter the Fully Qualified Domain Name (FQDN) for the registry’s ACR login server.

      The format for the FQDN is <REGISTRY_NAME>.azurecr.io, where <REGISTRY_NAME> is a unique value specified when the registry was created. Example: example.azurecr.io.
   3. In Repository, enter the name of the repository to scan. Example: library/alpine.
   4. Enter Tag numbers to scan, leave blank, or enter a wildcard (*) to scan all the tags.
   5. Optionally, enter Tags to exclude, to avoid scanning images with specified tags.
   6. In Credential, configure how Prisma Cloud authenticates with ACR.

      Select a credential from the drop-down list.

      If there are no credentials in the list, click Add new to create an Azure credential where the service principal authenticates with a password.
   7. In OS type, specify whether the repo holds Linux or Windows images.
   8. In Scanners scope, specify the collections of defenders to use for the scan.

      Console selects the available Defenders from the scope to execute the scan job according to the Number of scanners setting. For more information, see deployment patterns.
   9. In Number of scanners, enter the number of Defenders across which scan jobs can be distributed.
   10. In Cap, limit the number of images to scan.

       Set Cap to 5 to scan the five most recent images, or enter a different value to increase or decrease the limit. Set Cap to 0 to scan all images.
4. Select Add and scan.

   Verify that the images in the repository are being scanned under Monitor > Vulnerabilities > Images > Registries.
