# GitLab Secure **(ULTIMATE)**

GitLab can check your application for security vulnerabilities that may lead to unauthorized access,
data leaks, denial of services, and more. GitLab reports vulnerabilities in the merge request so you
can fix them before merging. The [Security Dashboard](security_dashboard/index.md) provides a
high-level view of vulnerabilities detected in your projects, pipeline, and groups. The [Threat Monitoring](threat_monitoring/index.md)
page provides runtime security metrics for application environments. With the information provided,
you can immediately begin risk analysis and remediation.

<i class="fa fa-youtube-play youtube" aria-hidden="true"></i>
For an overview of application security with GitLab, see
[Security Deep Dive](https://www.youtube.com/watch?v=k4vEJnGYy84).

## Quick start

Get started quickly with Dependency Scanning, License Scanning, Static Application Security
Testing (SAST), and Secret Detection by adding the following to your [`.gitlab-ci.yml`](../../ci/yaml/README.md):

```yaml
include:
  - template: Security/Dependency-Scanning.gitlab-ci.yml
  - template: Security/License-Scanning.gitlab-ci.yml
  - template: Security/SAST.gitlab-ci.yml
  - template: Security/Secret-Detection.gitlab-ci.yml
```

To add Dynamic Application Security Testing (DAST) scanning, add the following to your
`.gitlab-ci.yml` and replace `https://staging.example.com` with a staging server's web address:

```yaml
include:
  - template: Security/DAST.gitlab-ci.yml

variables:
  DAST_WEBSITE: https://staging.example.com
```

To ensure the DAST scanner runs *after* deploying the application to the staging server, review the [DAST full documentation](dast/index.md).

To add Container Scanning, follow the steps listed in the [Container Scanning documentation](container_scanning/index.md#requirements).

To further configure any of the other scanners, refer to each scanner's documentation.

### SAST configuration

You can set up and configure Static Application Security Testing
(SAST) for your project, without opening a text editor. For more details,
see [configure SAST in the UI](sast/index.md#configure-sast-in-the-ui).

### Override the default registry base address

By default, GitLab security scanners use `registry.gitlab.com/gitlab-org/security-products/analyzers` as the
base address for Docker images. You can override this globally by setting the variable
`SECURE_ANALYZERS_PREFIX` to another location. Note that this affects all scanners at once.

## Security scanning tools

GitLab uses the following tools to scan and report known vulnerabilities found in your project.

| Secure scanning tool                                                         | Description                                                            |
|:-----------------------------------------------------------------------------|:-----------------------------------------------------------------------|
| [Container Scanning](container_scanning/index.md) **(ULTIMATE)**             | Scan Docker containers for known vulnerabilities.                      |
| [Dependency List](dependency_list/index.md) **(ULTIMATE)**                   | View your project's dependencies and their known vulnerabilities.      |
| [Dependency Scanning](dependency_scanning/index.md) **(ULTIMATE)**           | Analyze your dependencies for known vulnerabilities.                   |
| [Dynamic Application Security Testing (DAST)](dast/index.md) **(ULTIMATE)**  | Analyze running web applications for known vulnerabilities.            |
| [API fuzzing](api_fuzzing/index.md) **(ULTIMATE)**                           | Find unknown bugs and vulnerabilities in web APIs with fuzzing.        |
| [Secret Detection](secret_detection/index.md)                                | Analyze Git history for leaked secrets.                                |
| [Security Dashboard](security_dashboard/index.md) **(ULTIMATE)**             | View vulnerabilities in all your projects and groups.                  |
| [Static Application Security Testing (SAST)](sast/index.md)                  | Analyze source code for known vulnerabilities.                         |
| [Coverage fuzzing](coverage_fuzzing/index.md) **(ULTIMATE)**                 | Find unknown bugs and vulnerabilities with coverage-guided fuzzing.    |

### Use security scanning tools with Pipelines for Merge Requests

The security scanning tools can all be added to pipelines with [templates](https://gitlab.com/gitlab-org/gitlab/-/tree/master/lib/gitlab/ci/templates/Security).
See each tool for details on how to use include each template in your CI/CD configuration.

By default, the application security jobs are configured to run for branch pipelines only.
To use them with [pipelines for merge requests](../../ci/merge_request_pipelines/index.md),
you may need to override the default `rules:` configuration to add:

```yaml
rules:
  - if: $CI_PIPELINE_SOURCE == "merge_request_event"
```

## Security Scanning with Auto DevOps

When [Auto DevOps](../../topics/autodevops/) is enabled, all GitLab Security scanning tools are configured using default settings.

- [Auto SAST](../../topics/autodevops/stages.md#auto-sast)
- [Auto Secret Detection](../../topics/autodevops/stages.md#auto-secret-detection)
- [Auto DAST](../../topics/autodevops/stages.md#auto-dast)
- [Auto Dependency Scanning](../../topics/autodevops/stages.md#auto-dependency-scanning)
- [Auto License Compliance](../../topics/autodevops/stages.md#auto-license-compliance)
- [Auto Container Scanning](../../topics/autodevops/stages.md#auto-container-scanning)

While you cannot directly customize Auto DevOps, you can [include the Auto DevOps template in your project's `.gitlab-ci.yml` file](../../topics/autodevops/customize.md#customizing-gitlab-ciyml).

## Maintenance and update of the vulnerabilities database

The scanning tools and vulnerabilities database are updated regularly.

| Secure scanning tool                                         | Vulnerabilities database updates          |
|:-------------------------------------------------------------|-------------------------------------------|
| [Container Scanning](container_scanning/index.md)            | Uses `clair`. The latest `clair-db` version is used for each job by running the [`latest` Docker image tag](https://gitlab.com/gitlab-org/gitlab/blob/438a0a56dc0882f22bdd82e700554525f552d91b/lib/gitlab/ci/templates/Security/Container-Scanning.gitlab-ci.yml#L37). The `clair-db` database [is updated daily according to the author](https://github.com/arminc/clair-local-scan#clair-server-or-local). |
| [Dependency Scanning](dependency_scanning/index.md)          | Relies on `bundler-audit` (for Ruby gems), `retire.js` (for NPM packages), and `gemnasium` (the GitLab tool for all libraries). Both `bundler-audit` and `retire.js` fetch their vulnerabilities data from GitHub repositories, so vulnerabilities added to `ruby-advisory-db` and `retire.js` are immediately available. The tools themselves are updated once per month if there's a new version. The [Gemnasium DB](https://gitlab.com/gitlab-org/security-products/gemnasium-db) is updated at least once a week. See our [current measurement of time from CVE being issued to our product being updated](https://about.gitlab.com/handbook/engineering/development/performance-indicators/#cve-issue-to-update). |
| [Dynamic Application Security Testing (DAST)](dast/index.md) | The scanning engine is updated on a periodic basis. See the [version of the underlying tool `zaproxy`](https://gitlab.com/gitlab-org/security-products/dast/blob/master/Dockerfile#L1). The scanning rules are downloaded at scan runtime. |
| [Static Application Security Testing (SAST)](sast/index.md)  | Relies exclusively on [the tools GitLab wraps](sast/index.md#supported-languages-and-frameworks). The underlying analyzers are updated at least once per month if a relevant update is available. The vulnerabilities database is updated by the upstream tools. |

Currently, you do not have to update GitLab to benefit from the latest vulnerabilities definitions.
The security tools are released as Docker images. The vendored job definitions that enable them use
major release tags according to [Semantic Versioning](https://semver.org/). Each new release of the
tools overrides these tags.
The Docker images are updated to match the previous GitLab releases, so users automatically get the
latest versions of the scanning tools without having to do anything. There are some known issues
with this approach, however, and there is a
[plan to resolve them](https://gitlab.com/gitlab-org/gitlab/-/issues/9725).

## Interacting with the vulnerabilities

> Introduced in [GitLab Ultimate](https://about.gitlab.com/pricing/) 10.8.

Each security vulnerability in the merge request report or the
[Security Dashboard](security_dashboard/index.md) is actionable. Click an entry to view detailed
information with several options:

- [Dismiss vulnerability](#dismissing-a-vulnerability): Dismissing a vulnerability styles it in
  strikethrough.
- [Create issue](#creating-an-issue-for-a-vulnerability): Create a new issue with the title and
  description pre-populated with information from the vulnerability report. By default, such issues
  are [confidential](../project/issues/confidential_issues.md).
- [Automatic Remediation](#automatic-remediation-for-vulnerabilities): For some vulnerabilities,
  a solution is provided for how to fix the vulnerability.

![Interacting with security reports](img/interacting_with_vulnerability_v13_3.png)

### View details of a DAST vulnerability

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/36332) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 13.1.

Vulnerabilities detected by DAST occur in the live web application. Rectification of these types of
vulnerabilities requires specific information. DAST provides the information required to
investigate and rectify the underlying cause.

To view details of DAST vulnerabilities:

1. To see all vulnerabilities detected:

   - In a project, go to the project's **{shield}** **Security & Compliance** page.
   - Only in a merge request, go the merge request's **Security** tab.

1. Click on the vulnerability's description. The following details are provided:

| Field            | Description                                                        |
|:-----------------|:------------------------------------------------------------------ |

| Solution         | Details of a recommended solution to the vulnerability (optional). |

#### Hide sensitive information in headers

HTTP request and response headers may contain sensitive information, including cookies and
authorization credentials. By default, content of specific headers are masked in DAST vulnerability
reports. You can specify the list of all headers to be masked. For details, see
[Hide sensitive information](dast/index.md#hide-sensitive-information).

### View details of an API Fuzzing vulnerability

> Introduced in [GitLab Ultimate](https://about.gitlab.com/pricing/) 13.7.

Faults detected by API Fuzzing occur in the live web application, and require manual investigation
to determine if they are vulnerabilities. Fuzzing faults are included as vulnerabilities with a
severity of Unknown. To facilitate investigation of the fuzzing faults, detailed information is
provided about the HTTP messages sent and received along with a description of the modification(s)
made.

Follow these steps to view details of a fuzzing fault:

1. You can view faults in a project, or a merge request:

   - In a project, go to the project's **{shield}** **Security & Compliance > Vulnerability Report**
     page. This page shows all vulnerabilities from the default branch only.
   - In a merge request, go the merge request's **Security** section and click the **Expand**
     button. API Fuzzing faults are available in a section labeled
     **API Fuzzing detected N potential vulnerabilities**. Click the title to display the fault
     details.

1. Click the fault's title to display the fault's details. The table below describes these details.

| Field            | Description                                                        |
|:-----------------|:------------------------------------------------------------------ |
| Description      | Description of the fault including what was modified.              |
| Project          | Namespace and project in which the vulnerability was detected.     |
| Method           | HTTP method used to detect the vulnerability.                      |
| URL              | URL at which the vulnerability was detected.                       |
| Request          | The HTTP request that caused the fault.                       |
| Unmodified Response | Response from an unmodified request. This is what a normal working response looks like. |
| Actual Response  | Response received from fuzzed request.                             |
| Evidence         | How we determined a fault occurred.                                |
| Identifiers      | The fuzzing check used to find this fault.                         |
| Severity         | Severity of the finding is always Unknown.                          |
| Scanner Type     | Scanner used to perform testing.                                   |

### Dismissing a vulnerability

To dismiss a vulnerability, you must set its status to Dismissed. This dismisses the vulnerability
for the entire project. Follow these steps to do so:

1. Select the vulnerability in the Security Dashboard.
1. Select **Dismissed** from the **Status** selector menu at the top-right.

You can undo this action by selecting a different status from the same menu.

#### Adding a dismissal reason

> Introduced in [GitLab Ultimate](https://about.gitlab.com/pricing/) 12.0.

When dismissing a vulnerability, it's often helpful to provide a reason for doing so. Upon setting a
vulnerability's status to Dismissed, a text box appears for you to add a comment with your
dismissal. Once added, you can edit or delete it. This allows you to add and update context for a
vulnerability as you learn more over time.

![Dismissed vulnerability comment](img/adding_a_dismissal_reason_v13_4.png)

#### Dismissing multiple vulnerabilities

> Introduced in [GitLab Ultimate](https://about.gitlab.com/pricing/) 12.9.

You can dismiss multiple vulnerabilities at once, providing an optional reason.
Selecting the checkboxes on the side of each vulnerability in the list selects that individual vulnerability.
Alternatively, you can select all the vulnerabilities in the list by selecting the checkbox in the table header.
Deselecting the checkbox in the header deselects all the vulnerabilities in the list.
Once you have selected some vulnerabilities, a menu appears at the top of the table that allows you to select a dismissal reason.
Pressing the "Dismiss Selected" button dismisses all the selected vulnerabilities at once, with the reason you chose.

![Multiple vulnerability dismissal](img/multi_select_v12_9.png)

### Creating an issue for a vulnerability

You can create an issue for a vulnerability by visiting the vulnerability's page and clicking
**Create issue**, which you can find in the **Related issues** section.

![Create issue from vulnerability](img/create_issue_from_vulnerability_v13_3.png)

This creates a [confidential issue](../project/issues/confidential_issues.md) in the project the
vulnerability came from, and pre-populates it with some useful information taken from the vulnerability
report. Once the issue is created, you are redirected to it so you can edit, assign, or comment on
it.

Upon returning to the group security dashboard, the vulnerability now has an associated issue next
to the name.

![Linked issue in the group security dashboard](img/issue.png)

### Automatic remediation for vulnerabilities

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/5656) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.7.

Some vulnerabilities can be fixed by applying the solution that GitLab
automatically generates. Although the feature name is Automatic Remediation, this feature is also commonly called Auto-Remediation, Auto Remediation, or Suggested Solutions. The following scanners are supported:

- [Dependency Scanning](dependency_scanning/index.md):
  Automatic Patch creation is only available for Node.js projects managed with
  `yarn`.
- [Container Scanning](container_scanning/index.md)

When an automatic solution is available, the button in the header shows **Resolve with merge request**:

![Resolve with Merge Request button](img/vulnerability_page_merge_request_button_v13_1.png)

Selecting the button creates a merge request with the solution.

#### Manually applying the suggested patch

To manually apply the patch that GitLab generated for a vulnerability:

1. Select the **Resolve with merge request** dropdown, then select **Download patch to resolve**:

   ![Resolve with Merge Request button dropdown](img/vulnerability_page_merge_request_button_dropdown_v13_1.png)

1. Ensure your local project has the same commit checked out that was used to generate the patch.
1. Run `git apply remediation.patch`.
1. Verify and commit the changes to your branch.

#### Creating a merge request from a vulnerability

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/9224) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.9.

In certain cases, GitLab allows you to create a merge request that automatically remediates the
vulnerability. Any vulnerability that has a
[solution](#automatic-remediation-for-vulnerabilities) can have a merge
request created to automatically solve the issue.

If this action is available, the vulnerability page or modal contains a **Create merge request** button.
Click this button to create a merge request to apply the solution onto the source branch.

![Create merge request from vulnerability](img/create_mr_from_vulnerability_v13_4.png)

### Managing related issues for a vulnerability

Issues can be linked to a vulnerability using the related issues block on the vulnerability page.
The relationship is uni-directional. The vulnerability page shows related issues, but the issue page
doesn't show the vulnerability it's related to. An issue can only be related to one vulnerability at
a time. Issues can be linked across groups and projects.

#### Adding a related issue

You can link an issue by clicking the **{plus}** button in the **Related Issues** block.

![Vulnerability related issues add button](img/vulnerability_related_issues_add_button_v13_2.png)

A text box appears that lets you type an issue number or paste an issue link. You can enter multiple
issues at once. Pressing the space bar after each issue number or link converts them to tags that
you can remove by clicking the **{close}** icon to the tag's right. Typing `#` followed by a number
shows an autocomplete menu. Click an issue in the menu to add it as a tag. When you're finished
entering issues, click the **Add** button to link the issues to the vulnerability. Alternatively,
click **Cancel** to exit without linking any issues.

![Vulnerability related issues text box tags animation](img/vulnerability_related_issues_text_box_tags_v13_2.gif)

### Removing a related issue

Click the **{close}** icon to right of an issue to remove it as a related issue. Note that this only
removes it as a related issue of the vulnerability; it doesn't modify or remove the issue itself.
You can link it to the vulnerability again if desired.

![Vulnerability related issues remove issue animation](img/vulnerability_related_issues_remove_v13_2.gif)

## Security approvals in merge requests

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/9928) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 12.2.

Merge Request Approvals can be configured to require approval from a member of your
security team when a merge request would introduce one of the following security issues:

- A security vulnerability
- A software license compliance violation

The security vulnerability threshold is defined as `high`, `critical`, or `unknown` severity. The
`Vulnerability-Check` approver group must approve merge requests that contain vulnerabilities.

When GitLab can assess vulnerability severity, the rating can be one of the following:

- `unknown`
- `low`
- `medium`
- `high`
- `critical`

The rating `unknown` indicates that the underlying scanner doesn't contain or provide a severity
rating.

### Enabling Security Approvals within a project

To enable the `Vulnerability-Check` or `License-Check` Security Approvals, a [project approval rule](../project/merge_requests/merge_request_approvals.md#adding--editing-a-default-approval-rule)
must be created. A [security scanner job](#security-scanning-tools) must be enabled for
`Vulnerability-Check`, and a [license scanning](../compliance/license_compliance/index.md#configuration)
job must be enabled for `License-Check`. When the proper jobs aren't configured, the following
appears:

![Unconfigured Approval Rules](img/unconfigured_security_approval_rules_and_jobs_v13_4.png)

If at least one security scanner is enabled, you can enable the `Vulnerability-Check` approval rule. If a license scanning job is enabled, you can enable the `License-Check` rule.

![Unconfigured Approval Rules with valid pipeline jobs](img/unconfigured_security_approval_rules_and_enabled_jobs_v13_4.png)

For this approval group, you must set the number of approvals required to greater than zero. You
must have Maintainer or Owner [permissions](../permissions.md#project-members-permissions)
to manage approval rules.

Follow these steps to enable `Vulnerability-Check`:

1. Navigate to your project's **Settings > General** and expand **Merge request approvals**.
1. Click **Enable**, or **Edit**.
1. Add or change the **Rule name** to `Vulnerability-Check` (case sensitive).

![Vulnerability Check Approver Rule](img/vulnerability-check_v13_4.png)

Once this group is added to your project, the approval rule is enabled for all merge requests.

Any code changes cause the approvals required to reset.

An approval is required when the latest security report in a merge request:

- Contains a vulnerability of `high`, `critical`, or `unknown` severity that is not present in the
  target branch. Note that approval is still required for dismissed vulnerabilities.
- Is not generated during pipeline execution.

An approval is optional when the security report:

- Contains no new vulnerabilities when compared to the target branch.
- Contains only new vulnerabilities of `low` or `medium` severity.

### Enabling License Approvals within a project

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/13067) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 12.3.

`License-Check` is a [security approval rule](#enabling-security-approvals-within-a-project)
you can enable to allow an individual or group to approve a merge request that contains a `denied`
license. For instructions on enabling this rule, see
[Enabling license approvals within a project](../compliance/license_compliance/index.md#enabling-license-approvals-within-a-project).

## Working in an offline environment

It is possible to run most of the GitLab security scanners when not
connected to the internet, in what is sometimes known as an offline,
limited connectivity, Local Area Network (LAN), Intranet, or "air-gap"
environment.

Read how to [operate the Secure scanners in an offline environment](offline_deployments/index.md).

## Using private Maven repos

If you have a private Apache Maven repository that requires login credentials,
you can use the `MAVEN_CLI_OPTS` environment variable
to pass a username and password. You can set it under your project's settings
so that your credentials aren't exposed in `.gitlab-ci.yml`.

If the username is `myuser` and the password is `verysecret` then you would
[set the following variable](../../ci/variables/README.md#create-a-custom-variable-in-the-ui)
under your project's settings:

| Type | Key | Value |
| ---- | --- | ----- |
| Variable | `MAVEN_CLI_OPTS` | `--settings mysettings.xml -Drepository.password=verysecret -Drepository.user=myuser` |

```xml
<!-- mysettings.xml -->
<settings>
    ...
    <servers>
        <server>
            <id>private_server</id>
            <username>${private.username}</username>
            <password>${private.password}</password>
        </server>
    </servers>
</settings>
```

## Outdated security reports

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/4913) in GitLab 12.7.

When a security report generated for a merge request becomes outdated, the merge request shows a warning
message in the security widget and prompts you to take an appropriate action.

This can happen in two scenarios:

1. Your [source branch is behind the target branch](#source-branch-is-behind-the-target-branch).
1. The [target branch security report is out of date](#target-branch-security-report-is-out-of-date).

### Source branch is behind the target branch

This means the most recent common ancestor commit between the target branch and the source branch is
not the most recent commit on the target branch. This is by far the most common situation.

In this case you must rebase or merge to incorporate the changes from the target branch.

![Incorporate target branch changes](img/outdated_report_branch_v12_9.png)

### Target branch security report is out of date

This can happen for many reasons, including failed jobs or new advisories. When the merge request shows that a
security report is out of date, you must run a new pipeline on the target branch.
You can do it quickly by following the hyperlink given to run a new pipeline.

## Troubleshooting

### Getting error message `sast job: stage parameter should be [some stage name here]`

When [including](../../ci/yaml/README.md#includetemplate) a `.gitlab-ci.yml` template
like [`SAST.gitlab-ci.yml`](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/gitlab/ci/templates/Security/SAST.gitlab-ci.yml),
the following error may occur, depending on your GitLab CI/CD configuration:

```plaintext
Found errors in your .gitlab-ci.yml:

* sast job: stage parameter should be unit-tests
```

This error appears when the included job's stage (named `test`) isn't declared in `.gitlab-ci.yml`.
To fix this issue, you can either:

- Add a `test` stage in your `.gitlab-ci.yml`.
- Change the default stage of the included security jobs. For example, with SpotBugs (SAST):

  ```yaml
  include:
    template: Security/SAST.gitlab-ci.yml

  spotbugs-sast:
    stage: unit-tests
  ```

[Learn more on overriding SAST jobs](sast/index.md#overriding-sast-jobs).
All the security scanning tools define their stage, so this error can occur with all of them.

### Getting warning messages `… report.json: no matching files`

This is often followed by the [error `No files to upload`](../../ci/pipelines/job_artifacts.md#error-message-no-files-to-upload),
and preceded by other errors or warnings that indicate why the JSON report wasn't generated. Please
check the entire job log for such messages. If you don't find these messages, retry the failed job
after setting `SECURE_LOG_LEVEL: "debug"` as a
[custom environment variable](../../ci/variables/README.md#custom-environment-variables).
This provides useful information to investigate further.

### Getting error message `sast job: config key may not be used with 'rules': only/except`

When [including](../../ci/yaml/README.md#includetemplate) a `.gitlab-ci.yml` template
like [`SAST.gitlab-ci.yml`](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/gitlab/ci/templates/Security/SAST.gitlab-ci.yml),
the following error may occur, depending on your GitLab CI/CD configuration:

```plaintext
Found errors in your .gitlab-ci.yml:

    jobs:sast config key may not be used with `rules`: only/except
```

This error appears when the included job's `rules` configuration has been [overridden](sast/index.md#overriding-sast-jobs)
with [the deprecated `only` or `except` syntax.](../../ci/yaml/README.md#onlyexcept-basic)
To fix this issue, you must either:

- [Transition your `only/except` syntax to `rules`](#transitioning-your-onlyexcept-syntax-to-rules).
- (Temporarily) [Pin your templates to the deprecated versions](#pin-your-templates-to-the-deprecated-versions)

#### Transitioning your `only/except` syntax to `rules`

When overriding the template to control job execution, previous instances of
[`only` or `except`](../../ci/yaml/README.md#onlyexcept-basic) are no longer compatible
and must be transitioned to [the `rules` syntax](../../ci/yaml/README.md#rules).

If your override is aimed at limiting jobs to only run on `master`, the previous syntax
would look similar to:

```yaml
include:
  - template: Security/SAST.gitlab-ci.yml

# Ensure that the scanning is only executed on master or merge requests
spotbugs-sast:
  only:
    refs:
      - master
      - merge_requests
```

To transition the above configuration to the new `rules` syntax, the override
would be written as follows:

```yaml
include:
  - template: Security/SAST.gitlab-ci.yml

# Ensure that the scanning is only executed on master or merge requests
spotbugs-sast:
  rules:
    - if: $CI_COMMIT_BRANCH == "master"
    - if: $CI_MERGE_REQUEST_ID
```

If your override is aimed at limiting jobs to only run on branches, not tags,
it would look similar to:

```yaml
include:
  - template: Security/SAST.gitlab-ci.yml

# Ensure that the scanning is not executed on tags
spotbugs-sast:
  except:
    - tags
```

To transition to the new `rules` syntax, the override would be rewritten as:

```yaml
include:
  - template: Security/SAST.gitlab-ci.yml

# Ensure that the scanning is not executed on tags
spotbugs-sast:
  rules:
    - if: $CI_COMMIT_TAG == null
```

[Learn more on the usage of `rules`](../../ci/yaml/README.md#rules).

#### Pin your templates to the deprecated versions

To ensure the latest support, we **strongly** recommend that you migrate to [`rules`](../../ci/yaml/README.md#rules).

If you're unable to immediately update your CI configuration, there are several workarounds that
involve pinning to the previous template versions, for example:

  ```yaml
  include:
    remote: 'https://gitlab.com/gitlab-org/gitlab/-/raw/12-10-stable-ee/lib/gitlab/ci/templates/Security/SAST.gitlab-ci.yml'
  ```

Additionally, we provide a dedicated project containing the versioned legacy templates.
This can be useful for offline setups or anyone wishing to use [Auto DevOps](../../topics/autodevops/index.md).

Instructions are available in the [legacy template project](https://gitlab.com/gitlab-org/auto-devops-v12-10).

#### Vulnerabilities are found, but the job succeeds. How can I have a pipeline fail instead?

This is the current default behavior, because the job's status indicates success or failure of the analyzer itself.
Analyzer results are displayed in the [job logs](../../ci/jobs/index.md#expand-and-collapse-job-log-sections),
[Merge Request widget](sast/index.md)
or [Security Dashboard](security_dashboard/index.md).
There is [an open issue](https://gitlab.com/gitlab-org/gitlab/-/issues/235772) in which changes to this behavior are being discussed.

### Enable or disable the basic security widget **(CORE ONLY)**

The basic security widget is under development but ready for production use.
It is deployed behind a feature flag that is **enabled by default**.
[GitLab administrators with access to the GitLab Rails console](../feature_flags.md)
can opt to disable it.

To enable it:

```ruby
# For the instance
Feature.enable(:core_security_mr_widget)
# For a single project
Feature.enable(:core_security_mr_widget, Project.find(<project id>))
```

To disable it:

```ruby
# For the instance
Feature.disable(:core_security_mr_widget)
# For a single project
Feature.disable(:core_security_mr_widget, Project.find(<project id>))
```
