Policies

Version history

Policies in GitLab provide security teams a way to require scans of their choice to be run whenever a project pipeline runs according to the configuration specified. Security teams can therefore be confident that the scans they set up have not been changed, altered, or disabled. You can access these by navigating to your project’s Security and Compliance > Policies page.

GitLab supports the following security policies:

Security policy project

All security policies are stored as YAML in a separate security policy project that gets linked to the development project, group, or sub-group. This association can be a one-to-many relationship, allowing one security policy project to apply to multiple development projects, groups, or sub-groups:

  • For self-managed GitLab instances, linked projects are not required to be in the same group or the same subgroup as the development projects to which they are linked.
  • For GitLab SaaS, the security policy project is required to be in the same top-level group as the development project, although, it is not necessary for the project to be in the same subgroup.

Security Policy Project Linking Diagram

Although it is possible to have one project linked to itself and to serve as both the development project and the security policy project, this is not recommended. Keeping the security policy project separate from the development project allows for complete separation of duties between security/compliance teams and development teams.

All security policies are stored in the .gitlab/security-policies/policy.yml YAML file inside the linked security policy project. The format for this YAML is specific to the type of policy that is stored there. Examples and schema information are available for the following policy types:

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.

Managing the linked security policy project

note
Only project Owners have the permissions to select, edit, and unlink a security policy project.

As a project owner, take the following steps to create or edit an association between your current project and a project that you would like to designate as the security policy project:

  1. On the top bar, select Main menu > Projects and find your project.
  2. On the left sidebar, select Security and Compliance > Policies.
  3. Select Edit Policy Project, and search for and select the project you would like to link from the dropdown list.
  4. Select Save.

To unlink a security policy project, follow the same steps but instead select the trash can icon in the modal.

Security Policy Project

Viewing the linked security policy project

All users who have access to the project policy page and are not project owners will instead view a button linking out to the associated security policy project. If no security policy project has been associated then the linking button does not appear.

Policy management

The Policies page displays deployed policies for all available environments. You can check a policy’s information (for example, description or enforcement status), and create and edit deployed policies:

  1. On the top bar, select Main menu > Projects and find your project.
  2. On the left sidebar, select Security and Compliance > Policies.

Policies List Page

Policy editor

Introduced in GitLab 13.4.

You can use the policy editor to create, edit, and delete policies:

  1. On the top bar, select Main menu > Projects and find your group.
  2. On the left sidebar, select Security and Compliance > Policies.
    • To create a new policy, select New policy which is located in the Policies page’s header. You can then select which type of policy to create.
    • To edit an existing policy, select Edit policy in the selected policy drawer.

The policy editor has two modes:

  • The visual Rule mode allows you to construct and preview policy rules using rule blocks and related controls.

    Policy Editor Rule Mode

  • YAML mode allows you to enter a policy definition in .yaml format and is aimed at expert users and cases that the Rule mode doesn’t support.

    Policy Editor YAML Mode

You can use both modes interchangeably and switch between them at any time. If a YAML resource is incorrect or contains data not supported by the Rule mode, Rule mode is automatically disabled. If the YAML is incorrect, you must use YAML mode to fix your policy before Rule mode is available again.

When you finish creating or editing your policy, save and apply it by selecting the Configure with a merge request button and then merging the resulting merge request. When you press this button, the policy YAML is validated and any resulting errors are displayed. Additionally, if you are a project owner and a security policy project has not been previously associated with this project, then a new project is created and associated automatically at the same time that the first policy merge request is created.

Managing projects in bulk via a script

You can use the Vulnerability-Check Migration script to bulk create policies or associate security policy projects with development projects. For instructions and a demonstration of how to use the Vulnerability-Check Migration script, see this video.

Troubleshooting

Branch name 'update-policy-<timestamp>' does not follow the pattern '<branch_name_regex>'

When you create a new security policy or change an existing policy, a new branch is automatically created with the branch name following the pattern update-policy-<timestamp>. For example: update-policy-1659094451.

If you have group or instance push rules that do not allow branch name patterns that contain the text update-policy-<timestamp>, you will get an error that states Branch name 'update-policy-<timestamp>' does not follow the pattern '<branch_name_regex>'.

The workaround is to amend your group or instance push rules to allow branches following the pattern update-policy- followed by an integer timestamp.
