Scan Images in Amazon Elastic Container Registry (ECR)

To scan a repository, Prisma Cloud has to authenticate with Amazon 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": "*"
        }
    ]
}
