### Description{% #description %}

ECR repositories should enable image scanning on push to detect known vulnerabilities before images are deployed. This reduces the risk of running vulnerable or compromised containers.

For `AWS::ECR::Repository` resources, `Properties.ImageScanningConfiguration.ScanOnPush` must be set to `true`. Resources missing `ImageScanningConfiguration`, or with `ScanOnPush` set to `false`, will be flagged.

To remediate, set `ImageScanningConfiguration.ScanOnPush` to `true` on the repository resource.

Secure configuration example:

```yaml
MyEcrRepository:
  Type: AWS::ECR::Repository
  Properties:
    RepositoryName: my-repo
    ImageScanningConfiguration:
      ScanOnPush: true
```

## Compliant Code Examples{% #compliant-code-examples %}

```yaml
AWSTemplateFormatVersion: "2010-09-11"
Resources:
  MyRepository:
    Type: AWS::ECR::Repository
    Properties:
      RepositoryName: "test-repository"
      ImageScanningConfiguration:
        ScanOnPush: "true"
```

```json
{
  "AWSTemplateFormatVersion": "2010-09-11T00:00:00Z",
  "Resources": {
