Prowler's Infrastructure as Code (IaC) provider enables scanning of local or remote infrastructure code for security and compliance issues using [Trivy](https://trivy.dev/). This provider supports a wide range of IaC frameworks, allowing assessment of code before deployment.

## Supported IaC Formats

Prowler IaC provider scans the following Infrastructure as Code configurations for misconfigurations and secrets:

| Configuration Type | File Patterns                                |
|--------------------|----------------------------------------------|
| Kubernetes         | `*.yml`, `*.yaml`, `*.json`                  |
| Docker             | `Dockerfile`, `Containerfile`                |
| Terraform          | `*.tf`, `*.tf.json`, `*.tfvars`              |
| Terraform Plan     | `tfplan`, `*.tfplan`, `*.json`               |
| CloudFormation     | `*.yml`, `*.yaml`, `*.json`                  |
| Azure ARM Template | `*.json`                                     |
| Helm               | `*.yml`, `*.yaml`, `*.tpl`, `*.tar.gz`, etc. |
| YAML               | `*.yaml`, `*.yml`                            |
| JSON               | `*.json`                                     |
| Ansible            | `*.yml`, `*.yaml`, `*.json`, `*.ini`, without extension |

## How It Works

- Prowler App leverages [Trivy](https://trivy.dev/docs/latest/guide/coverage/iac/#scanner) to scan local directories (or specified paths) for supported IaC files, or scans remote repositories.
- No cloud credentials or authentication are required for local scans.
- For remote repository scans, authentication can be provided via [git URL](https://git-scm.com/docs/git-clone#_git_urls), CLI flags or environment variables.
  - Check the [IaC Authentication](/user-guide/providers/iac/authentication) page for more details.
- Mutelist logic ([filtering](https://trivy.dev/latest/docs/configuration/filtering/)) is handled by Trivy, not Prowler.
- Results are output in the same formats as other Prowler providers (CSV, JSON, HTML, etc.).

## Prowler App

<VersionBadge version="5.14.0" />

### Supported Scanners

Scanner selection is not configurable in Prowler App. Default scanners, misconfig and secret, run automatically during each scan.

### Step 1: Access Prowler Cloud/App

1. Navigate to [Prowler Cloud](https://cloud.prowler.com/) or launch [Prowler App](/user-guide/tutorials/prowler-app)
2. Go to "Configuration" > "Cloud Providers"

    ![Cloud Providers Page](/images/prowler-app/cloud-providers-page.png)

3. Click "Add Cloud Provider"

4. Select "Infrastructure as Code"

5. Add the Repository URL and an optional alias, then click "Next"

### Step 2: Enter Authentication Details

6. Optionally provide the [authentication](/user-guide/providers/iac/authentication) details for private repositories, then click "Next"

### Step 3: Verify Connection & Start Scan

7. Review the provider configuration and click "Launch scan" to initiate the scan

## Prowler CLI

<VersionBadge version="5.8.0" />

### Supported Scanners

Prowler CLI supports the following scanners:

- [Vulnerability](https://trivy.dev/docs/latest/guide/scanner/vulnerability/)
- [Misconfiguration](https://trivy.dev/docs/latest/guide/scanner/misconfiguration/)
- [Secret](https://trivy.dev/docs/latest/guide/scanner/secret/)
- [License](https://trivy.dev/docs/latest/guide/scanner/license/)

By default, only misconfiguration and secret scanners run during a scan. To specify which scanners to use, refer to the [Specify Scanners](#specify-scanners) section below.

### Usage

Use the `iac` argument to run Prowler with the IaC provider. Specify the directory or repository to scan, frameworks to include, and paths to exclude.

#### Scan a Local Directory (default)

```sh
prowler iac --scan-path ./my-iac-directory
```

#### Scan a Remote GitHub Repository

```sh
prowler iac --scan-repository-url https://github.com/user/repo.git
```

##### Authentication for Remote Private Repositories

Authentication for private repositories can be provided using one of the following methods:

- **GitHub Username and Personal Access Token (PAT):**
  ```sh
  prowler iac --scan-repository-url https://github.com/user/repo.git \
    --github-username <username> --personal-access-token <token>
  ```
- **GitHub OAuth App Token:**
  ```sh
  prowler iac --scan-repository-url https://github.com/user/repo.git \
    --oauth-app-token <oauth_token>
  ```
- If not provided via CLI, the following environment variables will be used (in order of precedence):
    - `GITHUB_OAUTH_APP_TOKEN`
    - `GITHUB_USERNAME` and `GITHUB_PERSONAL_ACCESS_TOKEN`
- If neither CLI flags nor environment variables are set, the scan will attempt to clone without authentication or using the credentials provided in the [git URL](https://git-scm.com/docs/git-clone#_git_urls).

##### Mutually Exclusive Flags
- `--scan-path` and `--scan-repository-url` are mutually exclusive. Only one can be specified at a time.

#### Specify Scanners

To run only specific scanners, use the `--scanners` flag. For example, to scan only for vulnerabilities and misconfigurations:

```sh
prowler iac --scan-path ./my-iac-directory --scanners vuln misconfig
```

#### Exclude Paths

```sh
prowler iac --scan-path ./my-iac-directory --exclude-path ./my-iac-directory/test,./my-iac-directory/examples
```

### Output

Use the standard Prowler output options, for example:

```sh
prowler iac --scan-path ./iac --output-formats csv json html
```
