    Scan images in Amazon EC2 Container Registry (ECR)

    To scan a repository, Prisma Cloud has to authenticate with ECR using either an IAM user (service account) or IAM role. The minimum permissions policy required is
    AmazonEC2ContainerRegistryReadOnly
    . It is a managed, predefined policy. AWS managed policies grant the minimum set of permissions required for common use cases so you don’t need to spend a lot of time investigating permissions yourself.

    Authenticate Prisma Cloud to ECR

    The
    AmazonEC2ContainerRegistryReadOnly
     permissions policy is currently defined as follows:
    {
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PrismaCloudComputeECRScanning",
            "Effect": "Allow",
            "Action": [
                "ecr:BatchCheckLayerAvailability",
                "ecr:BatchGetImage",
                "ecr:DescribeImages",
                "ecr:DescribeRepositories",
                "ecr:GetAuthorizationToken",
                "ecr:GetDownloadUrlForLayer",
                "ecr:GetRepositoryPolicy",
                "ecr:ListImages"
            ],
            "Resource": "*"
        }
    ]
}
    Prerequisites:
     You have installed a Defender somewhere in your environment.
    1. Open Console and go to
      Defend > Vulnerabilities > Registry
      .
    2. Click
      Add registry
      .
    3. In the dialog, enter the following information:
      1. In
        Version
        , select
        Amazon EC2 Container Registry
        .
      2. In
        Registry
        , enter the URL for the registry. This should be of format:
        <acct_id>.dkr.ecr.<region>.amazonaws.com
      3. In
        Repository
        , enter the name of the repository to scan.
      4. In the
        Tag
         field, enter an image tag. Leave this field blank to scan all tags.
      5. You can use an IAM user, IAM role, or AWS STS.
      6. In
        OS type
        , specify whether the repo holds
        Linux
         or
        Windows
         images.
      7. 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.
      8. In
        Number of scanners
        , enter the number of Defenders across which scan jobs can be distributed.
      9. Set
        Cap
         to the number of most recent images to scan. Leaving
        Cap
         set to
        5
         will scan the 5 most recent images. Setting this field to
        0
         will scan all images.
      10. Click
        Add
        .
    4. Click the
      Save
       button.

    Results

    Verify that the images in the repository are being scanned.
    1. Go to
      Monitor > Vulnerabilities > Images > Registries
      .
      A progress indicator at the top right of the window shows the status of the current scan. As the scan of each image is completed, its findings are added to the results table.
    2. To get details about the vulnerabilities in an image, click on it.
      To force a specific repository to be scanned again, select
      Scan
       from the top right of the results table, then click on the specific registry to rescan.
