# Open Source Vulnerabilities (OSV) step configuration

You can scan your code repositories using [Open Source Vulnerabilities (OSV)](https://google.github.io/osv-scanner/) and ingest your results into Harness STO. OSV supports a [variety of languages and lockfiles](https://google.github.io/osv-scanner/supported-languages-and-lockfiles).

### Important notes for running OSV scans in STO <a href="#important-notes-for-running-osv-scans-in-sto" id="important-notes-for-running-osv-scans-in-sto"></a>

#### Root access requirements <a href="#root-access-requirements" id="root-access-requirements"></a>

If you want to add trusted certificates to your scan images at runtime, you need to run the scan step with root access.

You can utilize custom STO scan images and pipelines to run scans as a non-root user. For more details, refer [Configure your pipeline to use STO images from private registry](/security-testing-orchestration/troubleshooting-and-resources/sto-use-cases/set-up-sto-pipelines/configure-pipeline-to-use-sto-images-from-private-registry.md).

#### For more information <a href="#for-more-information" id="for-more-information"></a>

The following topics contain useful information for setting up scanner integrations in STO:

* [What's supported in STO](/security-testing-orchestration/new-to-sto/sto-whats-supported/sto-deployments.md)
* [Security Testing Orchestration FAQs](/security-testing-orchestration/troubleshooting-and-resources/faqs.md)
* [Optimize STO pipelines](/security-testing-orchestration/troubleshooting-and-resources/sto-use-cases/set-up-sto-pipelines/optimize-sto-pipelines.md)

### OSV step settings for STO scans <a href="#osv-step-settings-for-sto-scans" id="osv-step-settings-for-sto-scans"></a>

The recommended workflow is to add an OSV step to a Security or Build stage and then configure it as described below.

#### Scan <a href="#scan" id="scan"></a>

**Scan Mode**

This integration supports the following scan modes.

* **Orchestration** Configure the step to [run a scan](/security-testing-orchestration/new-to-sto/key-concepts/run-an-orchestrated-scan-in-sto.md) and then ingest, normalize, and deduplicate the results.
* **Ingestion** Configure the step to [read scan results from a data file](/security-testing-orchestration/new-to-sto/key-concepts/ingest-scan-results-into-an-sto-pipeline.md) and then ingest, normalize, and deduplicate the data.

**Scan Configuration**

The predefined configuration to use for the scan. All scan steps have at least one configuration.

#### Target <a href="#target" id="target"></a>

**Type**

* **Repository** Scan a codebase repo.

  In most cases, you specify the codebase using a code repo connector that connects to the Git account or repository where your code is stored. For information, go to [Configure codebase](/continuous-integration/use-harness-ci/use-harness-ci/codebase-configuration/create-and-configure-a-codebase.md).

**Target and Variant Detection**

When **Auto** is enabled for code repositories, the step detects these values using `git`:

* To detect the target, the step runs `git config --get remote.origin.url`.
* To detect the variant, the step runs `git rev-parse --abbrev-ref HEAD`. The default assumption is that the `HEAD` branch is the one you want to scan.

Note the following:

* **Auto** is not available when the **Scan Mode** is **Ingestion**.
* By default, **Auto** is selected when you add the step. You can change this setting if needed.

**Name**

The identifier for the [target](/security-testing-orchestration/new-to-sto/key-concepts/targets-and-baselines.md), such as `codebaseAlpha` or `jsmith/myalphaservice`. Descriptive target names make it much easier to navigate your scan data in the STO UI.

It is good practice to [specify a baseline](/security-testing-orchestration/new-to-sto/key-concepts/targets-and-baselines.md#every-target-needs-a-baseline) for every target.

**Variant**

The identifier for the specific variant to scan. This is usually the branch name, image tag, or product version. Harness maintains a historical trend for each variant.

#### Ingestion <a href="#ingestion" id="ingestion"></a>

**Ingestion File**

The path to your scan results when running an [Ingestion scan](/security-testing-orchestration/new-to-sto/key-concepts/ingest-scan-results-into-an-sto-pipeline.md), for example `/shared/scan_results/myscan.latest.sarif`.

* The data file must be in a [supported format](/security-testing-orchestration/new-to-sto/sto-whats-supported/scanners.md#supported-ingestion-formats) for the scanner.
* The data file must be accessible to the scan step. It's good practice to save your results files to a [shared path](/continuous-integration/new-to-harness-ci/key-concepts.md#stages) in your stage. In the visual editor, go to the stage where you're running the scan. Then go to **Overview** > **Shared Paths**. You can also add the path to the YAML stage definition like this:

  ```yaml
      - stage:
        spec:
          sharedPaths:
            - /shared/scan_results
  ```

#### Log Level <a href="#log-level" id="log-level"></a>

The minimum severity of the messages you want to include in your scan logs. You can specify one of the following:

* **DEBUG**
* **INFO**
* **WARNING**
* **ERROR**

#### Additional CLI flags <a href="#additional-cli-flags" id="additional-cli-flags"></a>

Use this field to run the [`osv`](https://google.github.io/osv-scanner/usage/) scanner with flags such as:

`--lockfile=/path/to/your/package-lock.json --lockfile=/path/to/another/Cargo.lock`

With these flags, the `osv` scanner scans vulnerabilities in the two specified lockfiles.

{% hint style="warning" %}
Passing additional CLI flags is an advanced feature. Harness recommends the following best practices:

* Test your flags and arguments thoroughly before you use them in your Harness pipelines. Some flags might not work in the context of STO.
* Don't add flags that are already used in the default configuration of the scan step.

  To check the default configuration, go to a pipeline execution where the scan step ran with no additional flags. Check the log output for the scan step. You should see a line like this:

  `Command [ scancmd -f json -o /tmp/output.json ]`

  In this case, don't add `-f` or `-o` to **Additional CLI flags**.
  {% endhint %}

#### Fail on Severity <a href="#fail-on-severity" id="fail-on-severity"></a>

Every STO scan step has a **Fail on Severity** setting. If the scan finds any vulnerability with the specified [severity level](/security-testing-orchestration/new-to-sto/key-concepts/severities.md) or higher, the pipeline fails automatically. You can specify one of the following:

* **`CRITICAL`**
* **`HIGH`**
* **`MEDIUM`**
* **`LOW`**
* **`INFO`**
* **`NONE`** — Do not fail on severity

The YAML definition looks like this: `fail_on_severity : critical # | high | medium | low | info | none`

#### Settings <a href="#settings" id="settings"></a>

You can use this field to specify environment variables for your scanner.

#### Additional Configuration <a href="#additional-configuration" id="additional-configuration"></a>

The fields under **Additional Configuration** vary based on the type of infrastructure. Depending on the infrastructure type selected, some fields may or may not appear in your settings. Below are the details for each field

* Override Security Test Image
  * [Container Registry](/security-testing-orchestration/troubleshooting-and-resources/sto-use-cases/set-up-sto-pipelines/configure-pipeline-to-use-sto-images-from-private-registry.md#step-level-override)
  * [Image Tag](/security-testing-orchestration/troubleshooting-and-resources/sto-use-cases/set-up-sto-pipelines/configure-pipeline-to-use-sto-images-from-private-registry.md#step-level-override)
* [Privileged](/continuous-integration/use-harness-ci/use-harness-ci/manage-dependencies/background-step-settings.md#privileged)
* [Image Pull Policy](/continuous-integration/use-harness-ci/use-harness-ci/manage-dependencies/background-step-settings.md#image-pull-policy)
* [Run as User](/continuous-integration/use-harness-ci/use-harness-ci/manage-dependencies/background-step-settings.md#run-as-user)
* [Set Container Resources](/continuous-integration/use-harness-ci/use-harness-ci/manage-dependencies/background-step-settings.md#set-container-resources)
* [Timeout](/continuous-integration/use-harness-ci/use-harness-ci/run-step-settings.md#timeout)

#### Advanced settings <a href="#advanced-settings" id="advanced-settings"></a>

In the **Advanced** settings, you can use the following options:

* [Conditional Execution](/harness-ai/use-harness-platform/pipelines/step-skip-condition-settings.md)
* [Failure Strategy](/harness-ai/use-harness-platform/pipelines/failure-handling/define-a-failure-strategy-on-stages-and-steps.md)
* [Looping Strategy](/harness-ai/use-harness-platform/pipelines/looping-strategies/looping-strategies-matrix-repeat-and-parallelism.md)
* [Policy Enforcement](/harness-ai/use-harness-platform/governance/policy-as-code/harness-governance-overview.md)

### Configure OSV as a Built-in Scanner <a href="#configure-osv-as-a-built-in-scanner" id="configure-osv-as-a-built-in-scanner"></a>

The OSV scanner is available as a [built-in scanner](/security-testing-orchestration/use-sto/set-up-sto-scans/built-in-scanners.md) in STO. Configuring it as a built-in scanner enables the step to automatically perform scans using the free version without requiring any licenses. Follow these steps to set it up:

1. Search for **SCA** in the step palette or navigate to the **Built-in Scanners** section and select the **SCA** step.
2. Select **OSV** from the list of scanners.
3. Expand the **Additional CLI Flags** section if you want to configure optional CLI flags.
4. Click **Add Scanner** to save the configuration.

The scanner will automatically use the free version, detect scan targets, and can be further configured by clicking on the step whenever needed.

### Proxy settings <a href="#proxy-settings" id="proxy-settings"></a>

This step supports private network connectivity if you're using Harness Cloud infrastructure. For information on connectivity options, see [Private network connectivity options](/harness-ai/use-harness-platform/references/private-network-connectivity/private-network-connectivity.md). When using proxy configurations, the `HTTPS_PROXY` and `HTTP_PROXY` variables are automatically set to route traffic through the secure tunnel. If there are specific addresses that you want to bypass the proxy, you can define those in the `NO_PROXY` variable. This can be configured in the **Settings** of your step.

If you need to configure a different proxy, you can manually set the `HTTPS_PROXY`, `HTTP_PROXY`, and `NO_PROXY` variables in the **Settings** of your step.

**Definitions of Proxy variables:**

* `HTTPS_PROXY`: Specify the proxy server for HTTPS requests, example `https://sc.internal.harness.io:30000`
* `HTTP_PROXY`: Specify the proxy server for HTTP requests, example `http://sc.internal.harness.io:30000`
* `NO_PROXY`: Specify the domains as comma-separated values that should bypass the proxy. This allows you to exclude certain traffic from being routed through the proxy.
