Scan execution policies (ULTIMATE)

• Group-level security policies were introduced in GitLab 15.2.
• Group-level security policies were enabled on GitLab.com in GitLab 15.4.

Group, subgroup, or project owners can use scan execution policies to require that security scans run on a specified schedule or with the project (or multiple projects if the policy is defined at a group or subgroup level) pipeline. Required scans are injected into the CI pipeline as new jobs with a long, random job name. In the unlikely event of a job name collision, the security policy job overwrites any pre-existing job in the pipeline. If a policy is created at the group-level, it will apply to every child project or subgroup. A group-level policy cannot be edited from a child project or subgroup.

This feature has some overlap with compliance framework pipelines, as we have not unified the user experience for these two features. For details on the similarities and differences between these features, see Enforce scan execution.

NOTE: Policy jobs are created in the test stage of the pipeline. If you modify the default pipeline stages, you must ensure that the test stage exists in the list. Otherwise, the pipeline fails to run and an error appears that states chosen stage does not exist.

Scan execution policy editor

NOTE: Only group, subgroup, or project Owners have the permissions to select Security Policy Project.

Once your policy is complete, save it by selecting Create via merge request at the bottom of the editor. You are redirected to the merge request on the project's configured security policy project. If one does not link to your project, a security policy project is automatically created. Existing policies can also be removed from the editor interface by selecting Delete policy at the bottom of the editor.

Most policy changes take effect as soon as the merge request is merged. Any changes that do not go through a merge request and are committed directly to the default branch may require up to 10 minutes before the policy changes take effect.

Scan execution policies schema

The YAML file with scan execution policies consists of an array of objects matching scan execution policy schema nested under the scan_execution_policy key. You can configure a maximum of 5 policies under the scan_execution_policy key. Any other policies configured after the first 5 are not applied.

When you save a new policy, GitLab validates its contents against this JSON schema. If you're not familiar with how to read JSON schemas, the following sections and tables provide an alternative.

Field	Type	Possible values	Description
scan_execution_policy	array of scan execution policy		List of scan execution policies (maximum 5)

Scan execution policy schema

Field	Type	Possible values	Description
name	string		Name of the policy. Maximum of 255 characters.
description (optional)	string		Description of the policy.
enabled	boolean	true, false	Flag to enable (true) or disable (false) the policy.
rules	array of rules		List of rules that the policy applies.
actions	array of actions		List of actions that the policy enforces.

pipeline rule type

This rule enforces the defined actions whenever the pipeline runs for a selected branch.

Field	Type	Possible values	Description
type	string	pipeline	The rule's type.
branches	array of string	* or the branch's name	The branch the given policy applies to (supports wildcard).

schedule rule type

This rule enforces the defined actions and schedules a scan on the provided date/time.

Field	Type	Possible values	Description
type	string	schedule	The rule's type.
branches	array of string	* or the branch's name	The branch the given policy applies to (supports wildcard).
cadence	string	CRON expression (for example, 0 0 * * *)	A whitespace-separated string containing five fields that represents the scheduled time.
agents	object		The name of the GitLab agents where cluster image scanning will run. The object key is the name of the Kubernetes cluster configured for your project in GitLab. You can use the optional value of the object to select and scan specific Kubernetes resources.

GitLab supports the following types of CRON syntax for the cadence field:

• A daily cadence of once per hour at a specified hour, for example: 0 18 * * *
• A weekly cadence of once per week on a specified day and at a specified hour, for example: 0 13 * * 0

Other elements of the CRON syntax may work in the cadence field, however, GitLab does not officially test or support them. The CRON expression is evaluated in UTC by default. If you have a self-managed GitLab instance and have changed the server timezone, the CRON expression is evaluated with the new timezone.

agent schema

Use this schema to define agents objects in the schedule rule type.

Field	Type	Possible values	Description
namespaces	array of string		The namespace that is scanned. If empty, all namespaces will be scanned.

Policy example

- name: Enforce Container Scanning in cluster connected through gitlab-agent for production and staging namespaces
  enabled: true
  rules:
  - type: schedule
    cadence: '0 10 * * *'
    agents:
      gitlab-agent:
        namespaces:
        - 'production'
        - 'staging'
  actions:
  - scan: container_scanning

scan action type

This action executes the selected scan with additional parameters when conditions for at least one rule in the defined policy are met.

Field	Type	Possible values	Description
scan	string	dast, secret_detection, sast, container_scanning, dependency_scanning	The action's type.
site_profile	string	Name of the selected DAST site profile.	The DAST site profile to execute the DAST scan. This field should only be set if scan type is dast.
scanner_profile	string or null	Name of the selected DAST scanner profile.	The DAST scanner profile to execute the DAST scan. This field should only be set if scan type is dast.
variables	object		A set of CI variables, supplied as an array of key: value pairs, to apply and enforce for the selected scan. The key is the variable name, with its value provided as a string. This parameter supports any variable that the GitLab CI job supports for the specified scan.

Note the following:

• You must create the site profile and scanner profile with selected names for each project that is assigned to the selected Security Policy Project. Otherwise, the policy is not applied and a job with an error message is created instead.
• Once you associate the site profile and scanner profile by name in the policy, it is not possible to modify or delete them. If you want to modify them, you must first disable the policy by setting the active flag to false.
• When configuring policies with a scheduled DAST scan, the author of the commit in the security policy project's repository must have access to the scanner and site profiles. Otherwise, the scan is not scheduled successfully.
• For a secret detection scan, only rules with the default ruleset are supported. Custom rulesets are not supported.
• A secret detection scan runs in normal mode when executed as part of a pipeline, and in historic mode when executed as part of a scheduled scan.
• A container scanning scan that is configured for the pipeline rule type ignores the agent defined in the agents object. The agents object is only considered for schedule rule types. An agent with a name provided in the agents object must be created and configured for the project.
• The Dependency Scanning and SAST scans use the default templates and run in a child pipeline.

Example security policies project

You can use this example in a .gitlab/security-policies/policy.yml file stored in a security policy project:

---
scan_execution_policy:
- name: Enforce DAST in every release pipeline
  description: This policy enforces pipeline configuration to have a job with DAST scan for release branches
  enabled: true
  rules:
  - type: pipeline
    branches:
    - release/*
  actions:
  - scan: dast
    scanner_profile: Scanner Profile A
    site_profile: Site Profile B
- name: Enforce DAST and secret detection scans every 10 minutes
  description: This policy enforces DAST and secret detection scans to run every 10 minutes
  enabled: true
  rules:
  - type: schedule
    branches:
    - main
    cadence: "*/10 * * * *"
  actions:
  - scan: dast
    scanner_profile: Scanner Profile C
    site_profile: Site Profile D
  - scan: secret_detection
- name: Enforce Secret Detection and Container Scanning in every default branch pipeline
  description: This policy enforces pipeline configuration to have a job with Secret Detection and Container Scanning scans for the default branch
  enabled: true
  rules:
  - type: pipeline
    branches:
    - main
  actions:
  - scan: secret_detection
  - scan: sast
    variables:
      SAST_EXCLUDED_ANALYZERS: brakeman
  - scan: container_scanning

In this example:

• For every pipeline executed on branches that match the release/* wildcard (for example, branch release/v1.2.1), DAST scans run with Scanner Profile A and Site Profile B.
• DAST and secret detection scans run every 10 minutes. The DAST scan runs with Scanner Profile C and Site Profile D.
• Secret detection, container scanning, and SAST scans run for every pipeline executed on the main branch. The SAST scan runs with the SAST_EXCLUDED_ANALYZER variable set to "brakeman".

Example for scan execution policy editor

You can use this example in the YAML mode of the scan execution policy editor. It corresponds to a single object from the previous example.

name: Enforce Secret Detection and Container Scanning in every default branch pipeline
description: This policy enforces pipeline configuration to have a job with Secret Detection and Container Scanning scans for the default branch
enabled: true
rules:
  - type: pipeline
    branches:
      - main
actions:
  - scan: secret_detection
  - scan: container_scanning
